Description

用于糖尿病治疗的蛋白、蛋白缀合物及其应用
本申请是申请号为201380018643.2、申请日为2013年5月17日、发明名称为“用于糖尿病治疗的蛋白、蛋白缀合物及其应用”的发明专利申请的分案申请。
技术领域
本发明属于生物制药领域,涉及一种用于糖尿病治疗的蛋白、蛋白缀合物及其应用。
背景技术
细胞因子是细胞内存在或分泌的有生物活性的大分子,大多为多肽类物质,如各种白介素、干扰素、集落刺激因子(CSF)、肿瘤坏死因子(TNF)。在正常机体内低表达或不表达,在异常状态(疾病、防御)时转录、翻译。细胞因子调节或修饰炎症或免疫反应中的细胞应答。它们通过与敏感细胞表面的特殊受体结合而激活生物应答。细胞因子往往在多种靶细胞上都有受体,因此反应多效性是细胞因子的普遍性质。同时,也可通过其它细胞因子或细胞因子受体产生第二介导。
对于一个高活性的细胞因子,必须存在控制其释放和限制其活性的机制。细胞因子的生物合成和释放可以通过其它细胞因子或外源因素来严格调节。现已发现了两种控制其活性的机制:一是受体拮抗剂(Ⅰ型抑制蛋白),它的结构与细胞因子同源,能与受体分子结合而不激发信号的传导,通过与细胞因子竞争而产生抑制作用;二是可溶性受体分子(Ⅱ型抑制蛋白),它同细胞受体竞争与细胞因子结合,从而产生抑制作用。大量实验证明这两种抑制反应有生理相关性。现在认为Ⅱ型抑制剂有着类似缓冲液的中和作用,从而限制细胞因子的全身作用。同时又允许细胞因子在局部达到高浓度,从而加强劳分泌样的作用。它们的重组表达形式具有药理活性。
白细胞介素1(IL-1)参与多种生理过程。IL-1通过诱发中性蛋白酶和其它细胞因子(肿瘤坏死因子TNF)的分泌,刺激各种造血细胞和其它细胞的增生,调节促炎反应,介导炎症中的组织损伤,包括刺激滑膜细胞和软骨细胞增殖并产生PGE2、胶原酶、磷脂酶A等,引起关节炎症;促进骨髓释放中性粒细胞,诱导单核细胞和多核粒细胞趋化浸润到炎性部位,在局部释放溶酶体酶,引起嗜碱性粒细胞和肥大细胞脱颗粒,释放炎性介质等。IL-1可以直接损害胰岛中生产胰岛素的β细胞。与IL-1相关的疾病包括:类风湿性关节炎、糖尿病、系统性红斑狼疮、硬皮病等其他免疫性疾病。
IL-1包括两个相关因子:IL-1α和IL-1β。另外还有一种相关多肽为IL-1受体拮抗剂(IL-lRa)。IL-1α、IL-1β均是通过与细胞表面的IL-1受体(IL-1R)结合,通过信号转导系统将信号传入细胞内发挥其生物活性。现已发现了两种类型的IL-1R:Ⅰ型受体(IL-1RI)和Ⅱ型受体(IL-1RⅡ)。Ⅰ型受体,又称T细胞受体,具有信号转导功能;Ⅱ型受体,又称B细胞受体,它可以和IL-1结合,但不转导信号。事实上,IL-1RⅡ承担了IL-1衰减子的作用,可称之为“诱捕”受体。当IL-1结合IL-1RⅠ时,即形成一个复合物,然后该复合物即与IL-1R附属蛋白(LI-1R AcP)形成一种高亲和力的结合。可能是由于IL-1RⅠ胞内部分与IL-1R-AcP结合形成的异源二聚体激发了IL-1信号的转导。另外,IL-1R的胞外部分,又称为可溶性受体,即Ⅰ型可溶性受体(sIL-1RⅠ)和Ⅱ型可溶性受体(sIL-1RⅡ),它们在机体的正常状态和疾病情况下均存在于循环体系中,可与IL-1α、IL-1β或IL-lRa结合而成为一种天然的"缓冲剂"。
Arend等(“Interleukin 1receptor antagonist:A new member of theinterleukin 1family.”J Clin Invest,1991,88(5):1445-1451)发现在细胞培养上清液和体液中有抑制IL-1活性的物质,将其命名为IL-1Ra。Eisenberg等(“Interleukin1receptor antagonist is a member of the interleukin 1gene family:evolution ofa cytokine control mechanism.”PNAS,1991,88(12):5232-5236)通过分子克隆技术分析IL-1Ra的基因长1.8kb,有编码177个氨基酸的开放阅读框;成熟的IL-1Ra蛋白有152个氨基酸,还有一个25个氨基酸的先导序列。其与IL-1β有26%~30%同源性,与IL-1α有19%同源性,基因结构与IL-1相似。因此,可以推测IL-lRa与IL-1结构相似的部分起到与受体结合的作用,但它不能引发跨膜转导信号。在疾病状态下,许多组织如滑膜、皮肤组织中的巨噬细胞都可产生IL-1Ra。人的正常皮肤、培养的角质细胞及单核细胞皆有IL-1Ra mRNA表达。IL-1Ra与IL-1受体结合后,本身无激动作用,但可消除或减轻IL-1的生物效应,从而影响机体的病理生理过程。IL-1和IL-1Ra之间的平衡决定IL-1在炎症过程中的作用。
大量实验证明,IL-1Ra具有抑制前列腺素生成、引起血清NO浓度、减低环氧合酶-2和胶原酶-1的表达量、阻止白细胞浸润及关节软骨蛋白聚糖的降解、拮抗IL-1β的促神经生长因子表达等功能,预示IL-1Ra在治疗类风湿性关节炎、淀粉样变性病、骨关节炎、过敏性脑脊髓炎等炎症疾病中有着广阔的应用前景。IL-1Ra也可改善肾炎、皮炎及呼吸道炎症,降低脓毒休克死亡率,提高热休克存活率,抑制骨髓瘤生长,提高角膜同种移植成功率。一些诱导IL-1Ra表达的物质,其中包括人血清IgA、皮质类固醇、非类固醇抗炎药物mofezolac、IL-4、IL-13、IFN、TGF-β、IL-6及其它经gp130转导信号的细胞因子,同样可用于治疗IL-1所致疾病。
IL-1Ra商品名为Kineret。Kineret(Anakinra,阿那白滞素)是一种重组的非糖基化的人IL-1Ra(rhIL-1Ra),由153个氨基酸组成,分子量为17.3KD,由美国Amgen公司开发。Kineret与天然的人IL-1Ra的区别在于它的氨基端增加了一个蛋氨酸残基。2001年11月14日,Kineret获得美国FDA的批准上市,用于治疗对一种或多种DMARD无效的中至重度的活动期成人类风湿性关节炎患者,以减轻其症状。欧洲专利药评估署于2001年11月21日批准Kineret在欧洲上市,与MTX联用治疗对单用MTX疗效欠佳类风湿性关节炎患者。目前,Kineret正在进行用于炎症性肠病(IBD)、气喘和移植物排异的临床试验。
糖尿病的发生与胰岛β细胞功能受损有关,随着患病时间的延长,胰岛β细胞功能将进行性衰退。目前已经发现,在由胰岛β细胞炎症引发β细胞破坏和功能损伤而导致的1型糖尿病中,前炎症因子IL-1β在抑制胰岛β细胞功能和促其凋亡的过程中发挥了重要作用。在2型糖尿病患者中,也观察到胰岛β细胞IL-1表达增强,同时IL-1Ra的表达减弱。IL-1Ra的不足似乎是遗传特性,因为编码IL-1Ra的基因其基因多态性和改变的血清IL-1Ra含量是相关联的。IL-1β可以促进胰岛炎症细胞因子表达,并增加免疫细胞的浸润从而引发组织炎症,并影响β细胞功能和胰岛素敏感性。在体外研究中,长期暴露于高浓度葡萄糖和由脂肪组织分泌的肽激素瘦素会诱使β细胞及胰岛产生并释放IL-1β,继而引起功能受损及β细胞凋亡。外源性添加IL-1受体拮抗剂,如IL-1Ra,可以保护β细胞免受高浓度葡萄糖和瘦素的损伤,并减少2型糖尿病患者的炎症标识。类似研究也证实,胰岛内生成的炎性介质与糖尿病密切相关(

等,“Increased Interleukin(IL)-1βMessenger RibonucleicAcid Expression inβ-Cells of Individuals with Type 2Diabetes and Regulationof IL-1βin Human Islets by Glucose and Autostimulation.”J Clin EndocrinolMetab,2008,93(10):4065-4074;Donath等,“Islet Inflammation Impairs thePancreatic {beta}-Cell in Type 2Diabetes.”Physiology(Bethesda).2009,24:325-331)。
在一项研究中(Ehses等,“IL-1antagonism reduces hyperglycemia and tissueinflammation in the type 2diabetic GK rat”,PNAS,2009,106(33):13998-14003),研究者着重探讨IL-1对胰岛炎症细胞因子产生以及对胰岛素作用的周围组织炎症的影响。研究者选择GK大鼠为研究对象。该大鼠是一种自发性非肥胖的2型糖尿病模型大鼠,会发生胰岛的炎症和周围组织的(肝脏、骨骼肌和脂肪组织)胰岛素抵抗。研究者发现,GK大鼠胰岛和肝脏组织大量表达IL-1β,体外给予大鼠IL-1Ra可以特异性阻断IL-1活性,降低胰岛炎症细胞因子的释放。体内试验也证实IL-1Ra可以改善GK大鼠的高血糖,改善β细胞功能和胰岛素抵抗。此外,IL-1Ra可以降低胰岛来源的前炎细胞因子如IL-1β、IL-6、TNFα、KC、MCP-1和MIP-1α水平并减少胰岛CD68+、MHC II+和CD53+免疫细胞的浸润。肝脏组织细胞因子表达也减少。因此,IL-1Ra能够改善β细胞功能,有可能治疗2型糖尿病。
瑞士苏黎世大学MarcY.Donath等人利用阿那白滞素进行了一项临床双盲试验,结果发现,阻断IL-1可以改善患者的高血糖及胰岛β细胞功能,同时降低血液中炎性标志物的水平。此外,Marc Y.Donath等人还利用抗IL-1抗体XOMA 052进行临床双盲试验,以了解其安全性和药代动力学,试验中患者对该药有很好的耐受性,未发现药物相关的严重不良反应。
在一个研究中,70名A1C>7.5%且BMI>27kg/m2的2型糖尿病患者被随机安排接受为期13周的阿那白滞素或安慰剂治疗。在撤销阿那白滞素39周后,与安慰剂组病人的数据对比,发现通过阿那白滞素阻滞IL-1可以带来PI/I比值及系统性炎症标识的改善,而这一改善在治疗撤除之后依然可以持续39周(Larsen等,“Sustained Effects of Interleukin-1Receptor Antagonist Treatment in Type 2Diabetes”,Diabetes Care 2009,32:1663-1668)。
综上所述,炎症因子是糖尿病发生的重要因素之一。除目前的传统治疗外,抗炎治疗可能成为治疗糖尿病的新途径。
由于微量的IL-1就可以引起完全的生物学效应,IL-1ra的浓度往往需要高于IL-1100倍以上才能有效地抑制IL-1的生物学效应。在类风湿性关节炎治疗过程中,阿那白滞素的用量高达100~150mg/d,因而对生物制药下游工艺和生产有很高的要求,对生物制药企业是一个挑战。IL-1Ra理论上可以作用于体内任何部位的IL-1受体,没有选择性。长期、大剂量使用是否会使病人因为免疫抑制导致感染增加也是一个疑问;尤其是糖尿病人本身就容易受到感染,而且不易治愈。频繁用药加重了病人的身体、心理和经济负担。另外,IL-lRa在体内半衰期只有4-6小时,消弱了效果,增加了使用剂量。因此,设计新型靶向性IL-1ra,改善糖尿病治疗效果,减少不必要免疫抑制,降低剂量,延长体内作用时间是新药开发的方向。

GLP-1、GLP-1类似物及GLP-1受体结合多肽:
胰高血糖素原包含有两种胰高血糖素样肽,即GLP-1和GLP-2。GLP-1主要由末端空肠、回肠和结肠的Langerhans细胞分泌,主要包括GLP-1(7-37)和GLP-1(7-36)-NH2两种形式。GLP-1(7-36)-NH2是人体内的GLP-1的自然存在形式,在GLP-1肽中,它的促进胰岛素分泌作用最强。
GLP-1(7-36)-NH2序列为:
HAEGTFTSDVSSYLEGQAAKEFIAWLVKGR-NH2
GLP-1(7-37)序列为:
HAEGTFTSDVSSYLEGQAAKEFIAWLVKGRG。
GLP-1在体内的表达和活性受到严密的调控。当N端第二位丙氨酸被二肽基肽酶(DPP-Ⅳ)水解后,形成无活性的GLP-1(9-36)-NH2,成为GLP-1R的体内天然拮抗剂。在体内,GLP-1经酶切后的几个代谢产物包括GLP-1(9-36)、GLP-1(7-35)和GLP-1(7-34)。GLP-1(9-36)-NH2是GLP-1的主要分解代谢产物,在体内的浓度可以高达GLP-1(7-36)-NH2的10倍。GLP-1在体内的半衰期不足5分钟,其新陈代谢的速率为12~13分钟。在生理状态下,完整的GLP-1主要是通过肾脏的排泄,由肾外组织协助排除。
GLP-1能够促进胰岛素分泌,而且这种促进作用是葡萄糖依赖性的,血糖越高,作用越强。GLP-1与胰岛β细胞细胞膜上的受体结合,通过增加细胞内cAMP,使K+-ATP酶磷酸化,导致K+通道关闭,细胞膜去极化,Ca2+通道开放,Ca2+内流,刺激胰岛素从细胞排出,从而促进胰岛素分泌。这种作用又是全方位的,影响前胰岛素基因的转录、翻译及剪切等各个功能环节。此外,GLP-1也能够上调β细胞中与糖代谢密切相关的基因(如葡萄糖激酶和葡萄糖转运蛋白-2),但胰岛素基因启动子可以部分不依赖PKA的方式被激活。
GLP-1也能够刺激胰岛β细胞增生,抑制其凋亡。研究发现GLP-1在非-STZ模型大鼠中能刺激β细胞新生,改善成年大鼠血糖的自身稳定。在新生GK大鼠中,经GLP-1或Exendin-4注射5日,血糖恒定状态显著改善,胰岛素水平升高,β细胞实体增大。继续应用上述药物,大鼠β细胞持续增加,成年时血糖控制能力显著提高。体外细胞培养发现,GLP-1能诱导小鼠成肌细胞株和胚胎干细胞分化为胰岛素表达细胞。在Zucker糖尿病大鼠模型中,β细胞凋亡的比例最高达20%以上,GLP-1的治疗能使凋亡细胞比例显著下降。研究发现,GLP-1能抑制链脲佐菌素(STZ)诱导的小鼠β细胞凋亡,而GLP-1R基因敲除小鼠的β细胞对STZ诱导凋亡的敏感性显著升高。
在血糖调节中,胰升糖素的作用和胰岛素相反,通过促进肝糖原分解增加血糖的浓度。在健康人、1型糖尿病和2型糖尿病患者中均证实,GLP-1能抑制胰升糖素的释放,但在健康人体中其作用程度小于糖尿病患者。给C肽阴性的狗注射GLP-1能降低血浆胰高血糖素水平,提示GLP-1抑制胰高血糖素的作用至少部分是不依赖于胰岛素的。
在对鼠、猪和人的一系列研究中发现,GLP-1可抑制胃肠道蠕动和胃液分泌,延迟胃排空。在人体,无论是正常人还是糖尿病患者,应用GLP-1均可使其产生短暂的饱胀感觉和食欲下降。
GLP-1受体(GLP-1R)是一个与G蛋白偶联的7个跨膜结构,以cAMP为主要第二信使。它属于G蛋白偶联受体B家族(分泌素家族)中的胰高血糖素受体亚家族,该家族最明显的特征是相对较长的胞外N端序列,通过3个二硫键形成一个球状结构域。人GLP-1受体与鼠受体有90%的同源性。解剖学的证据表明:鼠、猪和人肠道各段都可见GLP-1R细胞,不同种属间分布密度不同,分布规律相同,即从小肠和大肠的近端向远端细胞逐渐增大。
胰高血糖素原72-117的氨基酸序列参照Bell等,Nature 304 368-371(1983)。胰高血糖素原片段72-108通常称为GLP-l(l-37)。GLP-1(7-20)是已知的最短的促胰岛素的GLP-1类似物。
“GLP-1类似物”定义为GLP-l(l-37)的一个或多个氨基酸残基缺失或被另外的氨基酸残基取代,或者有一个或多个氨基酸残基插入原多肽序列。在一个优选的实施方式中,GLP-1类似物和对应的GLP-l(l-37)的不同氨基酸残基总数不超过20个,或不超过15个、10个、5个、4个、3个、2个,最好是1个。GLP-1类似物可以是GLP-l(l-37)的截断片段。GLP-1类似物也可以是GLP-1的N末端或C末端延伸后得到的序列。在某些实施方式中,GLP-1类似物包括C末端1-20个氨基酸的延长。在一种实施方式中,C末端的延伸序列是PSSGAPPPS-NH2或GPSSGAPPPS-NH2。在一种实施方式中,C末端延长包括1-6个带正电荷的氨基酸,如精氨酸、赖氨酸。在一种实施方式中,C末端延长包括1-6个带负电荷的氨基酸,如谷氨酸、天冬氨酸。在某些实施方式中,GLP-1类似物可以是修饰产物,例如烷基取代、酰化、聚乙二醇修饰等。
不同的GLP-1有不同的生物活性。GLP-1(7-36)-NH2刺激[14C]-氨基比林蓄积的能力是GLP-1(1-37)和GLP-1(1-36)-NH2的100倍;GLP-1(7-36)-NH2和GLP-1(7-37)-NH2有相当的活性和效果。GLP-1(9-36)-NH2对β细胞没有效果,在某些研究中甚至是腺苷酸环化酶的拮抗剂;而GLP-1(7-35)-OH和GLP-1(7-34)-OH明显是激动剂。GLP-1(7-35)-OH或GLP-1(7-37)-OH升高血浆中胰岛素水平的能力低于GLP-1(7-36)-NH2
GLP-1(7-36)-NH2与受体结合的部分主要是氨基酸残基7-21,尽管全长序列都可以在受体结合中起到协同作用。除氨基酸长链的骨架之外,序列第7(组氨酸)、10(甘氨酸)、12(苯丙氨酸)、13(苏氨酸)和15(天冬氨酸)的侧链都直接与受体作用。而序列第28(苯丙氨酸)和第29(异亮氨酸)对GLP-1形成能够被受体识别的构象很关键。有些研究表明序列第10(甘氨酸)、15(天冬氨酸)和17(丝氨酸)的氨基酸残基以及C末端对于GLP-1的促胰岛素作用很重要。C末端酰胺化和C末端最后的氨基酸残基对GLP-1作用的重要性不如N末端。
GLP-1受体拮抗剂主要来源于GLP-1(7-36)-NH2或exendin-4的N端删除或取代后的序列,包括但不局限于以下序列:

“Exendin-3类似物”定义为exendin-3的一个或多个氨基酸残基缺失或被另外的氨基酸残基取代,或者有一个或多个氨基酸残基插入原多肽序列。Exendin-3类似物包括那些与exendin-3序列有1-15个氨基酸残基差异的多肽。
“Exendin-4类似物”定义为exendin-4的一个或多个氨基酸残基缺失或被另外的氨基酸残基取代,或者有一个或多个氨基酸残基插入原多肽序列。在一种优选的实施方式中,exendin-4类似物和exendin-4的不同氨基酸残基总数可以是不超过15个、10个、5个、4个、3个、2个,最好是1个,例如亮氨酸14,苯丙氨酸25-exendin-4。Exendin-4类似物可以是exendin-4的截断片段,例如exendin-4(1-28)-NH2、exendin-4(1-30)、exendin-4(1-30)-NH2、亮氨酸14、苯丙氨酸25-exendin-4(1-28)-NH2、亮氨酸14、丙氨酸22、苯丙氨酸25-exendin-4(1-28)-NH2

GIP及GIP受体结合多肽
胃泌素抑制肽又称葡萄糖依赖性促胰岛素分泌多肽,简称GIP。当血糖浓度高时,GIP可以通过促进胰岛素分泌调节血糖。另外,GIP在脂肪细胞和脂肪代谢过程中起到重要作用。
人GIP序列:YAEGTFISDYSIAMDKIHQQDFVNWLLAQKGKKNDWKHNITQ。
“GIP类似物”定义为GIP的一个或多个氨基酸残基缺失或被另外的氨基酸残基取代,或者有一个或多个氨基酸残基插入原多肽序列。在一种实施方式中,GIP类似物与人GIP的序列至少有25%、30%、40%、50%、60%、70%、80%、90%相同。在一种优选的实施方式中,GIP类似物和人GIP的不同氨基酸残基总数可以是不超过20个、15个、10个、5个、4个、3个、2个,最好是1个。在某些实施方式中,氨基酸取代可以是第1、2、3、7、10、12、15、16、17、18、19、20、21、23、24、27、28和29位。GIP类似物可以是GIP(1-42)的截断片段。在一个实施方式中,GIP类似物包括GIP(1-42)从C末端去除1-12个氨基酸残基后的序列,例如GIP(1-38)、GIP(1-39)、GIP(1-30)-NH2等。在一种实施方式中,GIP类似物包括GIP(1-42)从N末端起至少12个氨基酸残基的多肽序列。在某些实施方式中,GIP类似物包括C末端1-20个氨基酸的延长。在一种实施方式中,C末端延长包括1-6个带正电荷的氨基酸,如精氨酸、赖氨酸。在一种实施方式中,C末端延长包括1-6个带负电荷的氨基酸,如谷氨酸、天冬氨酸。在某些实施方式中,GIP类似物可以是修饰产物,例如烷基取代、酰化、聚乙二醇修饰等。
GIP类似物及其衍生物可以见于多种文献。部分GIP激动剂可见于出版物,例如Salhanick等,Bioorg Med Chem Lett 2005,15(18):4114-4117;Green等,Diabetes 2005,7(5):595-604;Gault等,Biochem J 2002,367(Pt3):913-920;Gault等,J Endocrin 2003;176:133-141;Irwin等,Diabetes Obes Metab 11(6):603-610(epub 2009)等。其它GIP类似物的例子有N-AcGIP(LysPAL37)(Irwin等“A Novel,Long-Acting Agonist of Glucose-Dependent Insulinotropic Polypeptide Suitable for Once-Daily Administrationin Type 2 Diabetes”,J Pharmacol Exp Ther,2005vol.314no.3 1187-1194)、GIP(1-40)、GIP(1-30)-NH2、GIP(19-30)-NH2、GIP(1-14)(Hinke等,“Identification of abioactive domain in the amino-terminus of glucose-dependent insulinotropicpolypeptide(GIP)”,Biochimica et Biophysica Acta 2001,Vol.1547 143-155)。由于GIP的C末端片段有较强的促进脂肪生成能力,因此部分或全部去掉C末端是降低GIP激动剂在这方面作用的方法之一,例如GIP(1-30)-NH2。构效关系研究表明,GIP的19-30片段是胰岛素反应的关键(“The insulinotropic region of gastric inhibitory polypeptide;fragment analysis suggests the bioactive site lies between residues 19and30.”Can J Physiol Pharmacol.1996Jan;74(1):65-72)。
GIP活性的一个重要决定因素是多肽N-端被DPP-4酶水解为没有活性的GIP(3-42)。对GIP N末端端第1、2或3位的适当修饰,可以抵抗DPP-4的降解,甚至使GIP类似物的生物活性提高。与天然GIP相比,[D-Ala2]-GIP(1-42)在正常小鼠体内GIP受体是超级激动剂,而且这种超常活性与其对血液胰岛素的效果并不完全相关(“Dipeptidyl Peptidase IV-Resistant[D-Ala2]Glucose-Dependent Insulinotropic Polypeptide(GIP)ImprovesGlucose Tolerance in Normal and Obese Diabetic Rats”,Diabetes 2002 51:652-661)。
去除GIP的N末端氨基酸残基往往得到GIP受体拮抗剂。GIP(10-30)-NH2、GIP(6-30)-NH2和GIP(7-30)-NH2是GIP受体拮抗剂,其中GIP(6-30)-NH2与GIP受体的结合能力与GIP(1-42)相当(Gelling等,“GIP(6-30amide)contains the high affinity bindingregion of GIP and is a potent inhibitor of GIP1-42 action in vitro.”RegulPept.1997,69(3):151-154;“Postprandial stimulation of insulin release byglucose-dependent insulinotropic polypeptide (GIP).Effect of a specificglucose-dependent insulinotropic polypeptide receptor antagonist in the rat”,J Clin Invest.1996December 1;98(11):2440-2445)。其它GIP拮抗剂包括GIP(15-42)、GIP(15-30)、GIP(16-30)、GIP(17-30)。GIP类似物Pro3-GIP(“Characterization of thecellular and metabolic effects of a novel enzyme-resistant antagonist ofglucose-dependent insulinotropic polypeptide.”Biochem Biophys ResCommun.2002Feb 8;290(5):1420-6)体外在细胞中以及体内在糖尿病肥胖ob/ob小鼠中拮抗GIP作用(“Effects of the novel(Pro(3))GIP antagonist and exendin(9-39)amideon GIP-and GLP-1-induced cyclic AMP generation,insulin secretion andpostprandial insulin release in obese diabetic(ob/ob)mice:evidence that GIPis the major physiological incretin.”Diabetologia.2003Feb;46(2):222-30;“Effects of the novel(Pro(3))GIP antagonist and exendin(9-39)amide on GIP-andGLP-1-induced cyclic AMP generation,insulin secretion and postprandialinsulin release in obese diabetic(ob/ob)mice:evidence that GIP is the majorphysiological incretin.Diabetologia.2003Feb;46(2):222-30)。成年、高脂肪食物喂养的糖尿病小鼠连续50天注射Pro3-GIP后体重降低,脂肪组织堆积减少,葡萄糖、糖化血红蛋白、胰岛素水平显著改善,肌肉和肝脏的甘油三脂水平下降(McClean等,“GIPreceptorantagonism reverses obesity,insulin resistance and associated metabolicdisturbances induced in mice by prolonged consumption of high fat diet.”Am JPhysiol Endocrinol Metab.2007Dec;293(6):E1746-55)。
2型糖尿病的特征包括不同程度的胰岛素抵抗和胰岛β细胞功能障碍。在欧洲和美国,胰岛素抵抗和肥胖是糖尿病患者的主要病理特证。在亚洲,胰岛素分泌能力受损是主要原因。因此,GIP激动剂可能对于胰岛素分泌能力受损的患者,尤其是亚洲患者有益,而GIP抑制剂可能对于胰岛素抵抗的肥胖患者,尤其是欧美患者有帮助。
在某些实施方式中,与白介素-1受体结合多肽组成融合蛋白或二聚蛋白的是GIP激动剂、GIP抑制剂、GLP-1/GIP受体双激动剂、胰高血糖素/GIP受体双激动剂、GLP-1/GIP/胰高血糖素受体三激动剂(如WO/2010/011439、WO2010148089A1、US2012/0172295、US2011/0166062、US2012/0322725中提到的)、GLP-1激动剂/GIP抑制剂,或嵌合多肽(例如HG-GIP(3-30)-NH2、HG-GIP(3-30)-exendin-4(31-39)-NH2、Ser2-GIP(1-30)-NH2、Ser2-GIP(1-30)-exendin-4(31-39)-NH2、dAla2-GIP(1-30)-exendin-4(31-39)-NH2)。在本发明中,GIP受体结合多肽可以是上述任何与GIP受体有结合能力的多肽序列。GIP受体结合多肽包括GIP类似物在内的任何与GIP受体有GIP(1-42)的0.1%、0.2%、0.3%、0.4%、0.5%、0.6%、0.7%、0.8%、0.9%、1%、5%、10%、20%、30%、40%、50%、60%、70%、80%、90%、100%或更高结合能力的多肽序列及其衍生物。
GIP在体外有刺激β细胞增殖、保护β细胞生存的效果(“Glucose-DependentInsulinotropic Polypeptide Is a Growth Factor for beta(INS-1)Cells byPleiotropic Signaling.”Mol Endocrinol.2001Sep;15(9):1559-70;“Mechanisms ofmitogenic and anti-apoptotic signaling by glucose-dependent insulinotropicpolypeptide in beta(INS-1)-cells”,J Endocrinol.2002Aug,174(2):233-46;“Glucose-dependent insulinotropic polypeptide promotes beta-(INS-1)cellsurvival via cyclic adenosine monophosphate-mediated caspase-3inhibition andregulation of p38 mitogen-activated protein kinase”,Endocrinology.2003Oct,144(10):4433-45)。多项研究表明GIP类似物在2型糖尿病大鼠模型和INS-1β细胞中有很强的生存保护能力(“A GIP receptor agonist exhibits beta-cell anti-apoptoticactions in rat models of diabetes resulting in improved beta-cell functionand glycemic control”,PLoS One.2010Mar 9;5(3):e9590;“GIP stimulation ofpancreatic beta-cell survival is dependent upon phosphatidylinositol 3-kinase(PI3-K)/protein kinase B(PKB)signaling,inactivation of the forkheadtranscription factor Foxo1 and downregulation of bax expression.J BiolChem.2005,280(23):22297-307)。
由于GIP对胰岛β细胞的保护作用,GIP与白介素-1受体结合多肽组成融合蛋白、二聚蛋白或交联蛋白能够产生更好的效果。在本发明中,GIP受体结合多肽与白介素-1受体结合多肽的连接方式,可以参照GLP-1受体结合多肽与白介素-1受体结合多肽的连接方式。
白介素-1受体拮抗蛋白:
“白介素-1受体拮抗蛋白”包括白介素-1受体拮抗剂(IL-1ra)及其类似物和衍生物。
IL-1受体家族包括几个受体,因此有几种不同的激动剂和拮抗剂。这些拮抗剂不一定与相同的IL-1家族受体结合。这里IL-1ra用来代表所有IL-1受体家族受体的所有IL-1拮抗剂。IL-1ra包括人IL-1Ra(hIL-1Ra)及其类似物、衍生物或功能等同物。功能等同物具有hIL-1Ra的生物活性,例如可以结合IL-1受体,不产生下游信号传递,并阻止IL-1结合IL-1受体。例子可以参考美国专利号6096728、美国专利号6541623、美国专利号6365726和美国专利号6399573。
优选的IL-lra(包括糖基化和非糖基化的)的制备和使用方法的描述见美国专利号5,075,222、WO 91/08285、WO 91/17184、AU 9173636、WO 92/16221和WO 96/22793。具体而言,美国专利号5,075,222描述了3种形式的IL-1Ra。第一个IL-lRaα的特征是在SDS-PAGE上的分子量为22-23kD,等电点大约是4.8,用大约含52mM NaCl的Tris缓冲液(pH 7.6)从Mono Q FPLC柱洗脱。第二个是IL-1Raβ,是分子量22-23kD的蛋白,用含48mM NaCl的Tris缓冲液从Mono Q FPLC柱洗脱。IL-lRaα和IL-1Raβ都是糖基化的。第三个是IL-lRax,分子量约20kD,用含有大约48mM NaCl的Tris缓冲液从Mono Q FPLC柱洗脱,无糖基化。这三种拮抗剂有类似的功能和免疫学活性。
目前已知IL-1Ra包括一种分泌型亚型(sIL-1Ra)和三种细胞内亚型(icIL-1Ra1、2、3)。

其中第70位和第117位的两个半胱氨酸可以形成二硫键。
本发明中的IL-1ra及其类似物可以使用生物工程技术制备和生产。为了蛋白表达和生产的便利,甲硫氨酸可以根据需要添加到本发明中各蛋白序列的N末端,而不会影响原序列的生物活性。阿那白滞素即是在非糖基化hIL-1Ra的N末端加入甲硫氨酸。
在有些实施方式中,IL-1ra包含一个或多个糖基化基团。
本发明中IL-1ra的氨基酸序列可以改变而不影响其生物活性。例如,一个IL-1ra类似物可以包含一个或多个保守氨基酸取代。保守氨基酸取代是一个氨基酸残基被另一个有相似侧链的氨基酸残基取代。文献中根据氨基酸残基侧链的性质对氨基酸残基进行分类。碱性侧链氨基酸残基包括赖氨酸、精氨酸、组氨酸;酸性侧链及其酰胺侧链氨基酸残基包括天冬氨酸、谷氨酸、天冬酰胺、谷氨酰胺;小脂肪族、非极性或弱极性侧链氨基酸残基包括甘氨酸、丙氨酸、苏氨酸、丝氨酸、脯氨酸;大脂肪族、非极性侧链氨基酸残基包括亮氨酸、异亮氨酸、缬氨酸;芳香族氨基酸残基包括苯丙氨酸、色氨酸、酪氨酸;含硫侧链氨基酸残基包括半胱氨酸、甲硫氨酸。
本发明中涉及的IL-1ra的类似物包括在IL-1ra的氨基酸序列中的部分氨基酸残基缺失(缺失类似物)、被其它天然或非天然氨基酸残基取代(取代类似物)或插入(插入类似物)。IL-1ra缺失类似物通常可以有大约1-50个氨基酸残基的缺失,更常见的是1-10个残基缺失。IL-1ra插入类似物可以包括在IL-1ra的N末端或C末端的融合,以及1个或多个氨基酸残基插入至IL-1ra的内部序列。IL-1ra的末端插入包括嵌合蛋白。在一种实施方式中,嵌合蛋白包括IL-1ra与人免疫球蛋白重链或轻链的所有或部分恒定区。优选的嵌合蛋白的免疫球蛋白部分可以包含除人免疫球蛋白(如IgG,IgA,IgM或IgE)重链恒定区的第一个结构域外的所有恒定区。每个免疫球蛋白部分的任何氨基酸残基都可以缺失或用一个或多个氨基酸残基取代,或可以插入一个或多个氨基酸残基,只要所述IL-1ra仍然拮抗IL-1受体,而且所述免疫球蛋白部分表现出一个或多个其特征性质。IL-1ra末端的嵌合蛋白也可以包括部分或全部人白蛋白序列,白蛋白部分的任何氨基酸残基都可以缺失或用一个或多个氨基酸残基取代,或可以插入一个或多个氨基酸残基。
本发明所述白介素-1受体拮抗蛋白类似物与IL-1Ra大致同源。本文所用的术语“大致同源”是指同源的程度超过60%、70%、80%、90%,甚至超过95%。本文所述同源百分比按Dayhoff(Atlas of Protein Sequence and Structure,5:124(1972),NationalBiochemical Research Foundation,Washington,D.C.)所述方法计算。
IL-1ra可以对白介素-1受体有hIL-1Ra的1%、2%、3%、4%、5%、10%、20%、30%、40%、50%、60%、70%、80%、90%、100%或更高的生物活性。
本领域技术人员可以制备化学或生物修饰的IL-1ra及其类似物、衍生物。用糖基化、非糖基化或去糖基化IL-1ra和IL-1ra类似物可以制备缀合物,所用化学修饰基团包括水溶性聚合物(如聚乙二醇)和脂肪酸。一个IL-1ra类似物可以包含一个或多个修饰基团。化学修饰基团一般通过IL-1ra的氨基酸的α-或ε-氨基或活性硫羟基连接到IL-1ra。具有游离氨基的氨基酸残基包括赖氨酸残基和N末端的氨基酸残基。具有活性硫羟基的氨基酸残基包括半胱氨酸残基。
IL-1ra序列中的氨基酸残基特异性取代可以有特殊用途,比如加入半胱氨酸或赖氨酸对于按下述实施方法连接修饰基团以形成缀合物是有利的。此外,可以在IL-1ra的序列中加入或缺失N-连接或O-连接的糖基化位点。天冬酰胺连接的糖基化识别位点包括一个由适当的细胞糖基化酶识别的三肽序列Asn-Xaa-Ser/Thr,这里Xaa可以是Pro以外的任何天然氨基酸。在成熟的hIL-1Ra中,第84位的天冬酰胺是一个糖基化位点。根据糖基化程度的不同,糖基化IL-1ra的分子量可以不同。融合蛋白、二聚蛋白或交联蛋白中的白介素-1受体拮抗蛋白部分可以通过半胱氨酸侧链巯基与修饰基团(例如聚乙二醇)相连。
成熟hIL-1Ra的氨基酸残基的编号依照以下氨基酸序列,N末端第一个氨基酸残基的位置为第一位,序列为:

上述天然IL-1ra序列有4个半胱氨酸(C66、C69、C116、C122)。根据本发明中的实施方法,与马来酰亚胺或卤代乙酰基(例如I-CH2-CO-)活化的修饰基团(例如单聚乙二醇)反应的IL-1ra特定位点为116位的半胱氨酸(C116)。在人IL-1ra中,其它3个半胱氨酸不易与马来酰亚胺或卤代乙酰基活化的修饰基团反应。为将修饰基团连接到IL-1ra的不同位点,或者使IL-1ra有一个以上的修饰基团,可以用半胱氨酸取代特定位点的氨基酸残基。IL-1ra类似物包括半胱氨酸添加到蛋白的N末端或C末端的序列,或用半胱氨酸取代原位点6、8、9、84或141的氨基酸残基的序列,或者116位的半胱氨酸被丝氨酸取代,或者4个半胱氨酸中一个或多个被丝氨酸取代。除单修饰基团的IL-1ra之外,IL-1ra还可以包括上述变化的组合,从而有一个以上的半胱氨酸与修饰基团反应。

这些IL-1ra类似物都可以用于合成本发明的融合蛋白、二聚蛋白或交联蛋白。
修饰基团
融合蛋白可以包含1个或多个修饰基团。修饰基团能够提供融合蛋白、二聚蛋白或交联蛋白需要的特性。例如,修饰基团可以降低蛋白在各种环境下(如消化道,血液)的降解速率。优选的修饰基团是那些允许蛋白保留相当的与原受体结合活性的基团。优选的修饰基团包括两性基团、水溶性基团或者使修饰后的蛋白比未修饰的蛋白更低亲脂性、更高水溶性的基团。修饰基团可以包含可降解连接基、易于水解的连接基,如丙交酯、乙交酯、碳酸、酯、氨基甲酸酯。这种方法可以使聚合物降解成小分子量片段。
修饰基团可以包括一个或多个亲水基团、亲脂基团、两性基团、成盐基团、间隔基团、连接基团、封端基团或这些基团的组合。各种基团可以以共价键,或以可水解或不可水解的键连接在一起。代表性亲水基团、亲脂基团和两性基团介绍如下。
亲水基团
亲水基团的实例包括PAG基团、多糖、聚山梨醇酯以及这些基团的组合物。
聚亚烷基二醇基团(PAG)由多个亚烷基二醇单体组成。在一个实施例中,所有单体是相同的(例如聚乙二醇(PEG)或聚丙二醇(PPG))。在另一个实施例中,亚烷基二醇单体是不同的。聚合体可以是无规共聚物(例如环氧乙烷和环氧丙烷的共聚物),或者分枝或接枝共聚物。
本文使用的“PEG”或聚乙二醇指任何水溶性聚乙二醇或聚氧化乙烯。聚乙二醇的化学结构式为-(CH2CH2O)n-,其中n可以是从2到2000的整数。PEG的一端通常是相对没有活性的官能团,如烷基或烷氧基等。使用甲氧基封端的PEG命名为mPEG,结构式CH3O(CH2CH2O)n-,但一般仍然称为PEG。PEG20K指分子量为20,000聚乙二醇分子。
PEG另一端通常是活化官能团或者易于形成共价键的官能团,例如氨基、羧基、羟基、巯基、醛等。PEG-马来酰亚胺可以与半胱氨酸侧链的巯基通过迈克尔加成反应接合;PEG-碘代乙酰基(CO-CH2-I)与巯基-SH反应形成稳定的硫醚键;PEG-NHS(琥珀酰亚胺)可以与氨基酸α氨基或赖氨酸侧链ε-氨基通过亲核取代反应(酰化)接合;PEG-醛与多肽上的氨基在还原剂(如氰基硼氢化钠)作用下可以通过还原性烷基化反应接合。
本发明中使用的商业PEG试剂包括,但不局限于,mPEG-SC(甲氧基-PEG-琥珀酰亚胺基碳酸酯)、mPEG-NHS(SCM)(或mPEG-SPA,单甲氧基聚乙二醇丙酸琥珀酰亚胺酯)、NHS-PEG-NHS、mPEG-CHO(甲氧基-PEG-丙醛)、ALD-PEG-ALD(乙醛-PEG-乙醛)、PEG-Ts(甲氧基-PEG-甲苯磺酸)、Ts-PEG-Ts(甲苯磺酸-PEG-甲苯磺酸)、mPEG-CDI(甲氧基-PEG-羰基咪唑)、CDI-PEG-CDI(羰基咪唑-PEG-羰基咪唑)、mPEG-NPC(甲氧基-PEG-硝基苯基碳酸酯)、mPEG-ISC(PEG-异氰酸酯)、ISC-PEG-ISC(异氰酸酯-PEG-异氰酸酯)、mPEG-EPO(甲氧基-PEG-环氧化物)、EPO-PEG-EPO(环氧化物-PEG-环氧化物)、mPEG-Mal(甲氧基-PEG-马来酰亚胺)、Mal-PEG-Mal(马来酰亚胺-PEG-马来酰亚胺)、马来酰亚胺-PEG-NHS、马来酰亚胺-PEG-NH2、马来酰亚胺-PEG-COOH、PEG-乙烯基砜衍生物、(VS-PEG-X、X=NHS、马来酰亚胺、NH2、COOH等)、PEG-碘代乙酰胺(iodo acetyl)衍生物(IA-PEG-X、X=NHS、马来酰亚胺、NH2、COOH等)、mPEG-OPSS(甲氧基-PEG-邻二硫吡啶(orthopyridyl disulfide))、OPSS-PEG-NHS(邻二硫吡啶-PEG-琥珀酰亚胺酯)、OPSS-PEG-NH2、OPSS-PEG-OPSS。
本发明中的PEG分子可以是直链的、支链的、分叉的或哑铃状的PEG。在一个实施例中,支链PEG可以用通式R(-PEG-nOH)m表示,其中R(通常是多羟基的)是核心基团,例如季戊四醇、糖、赖氨酸或甘油;m代表支链数,可以是从2起到核心基团附着位点最大数目;n代表PEG片段的数量,每个支链上的PEG片段的数量可以不等。在另一个实施例中,支链PEG可以用通式(CH3O-PEG-n)pR-Z表示,p等于2或3,R是赖氨酸或甘油,Z代表可以进行反应的活化官能团。在一个实施例中,分叉PEG用通式PEG(-L-X)n表示,L是连接基,X是末端活化官能团。
PEG可以是多分散的,多分散指数小于1.05。PEG基团也可以是单分散的。单分散指PEG具有单一的长度(分子量),而不是各种近似长度(分子量)的混合物。
术语烷基包括饱和的直链或支链烃基。
术语烷氧基包括自由基“烷基-O-”。代表性的例子是甲氧基、乙氧基、丙氧基(例如1-丙氧基和2-丙氧基)、丁氧基(例如1-丁氧基、2-丁氧基和2-甲基-2-丙氧基)、戊氧基、己氧基等。
糖基团
本发明中的多肽或蛋白可以包含糖基化位点。糖基团能够改善药物的药效和药物动力学特征,并在药物寻靶和药物转运中起作用。糖基团可以是O-连接或N-连接。O-连接一般是在丝氨酸或苏氨酸羟基的氧原子上,N-连接是在天冬酰胺侧链酰胺的氮原子上。GLP-1受体结合多肽一般不会被糖基化。但GLP-1-PSSGAPPPS-IgG Fc中,C末端延伸的最后一个氨基酸残基丝氨酸可以被糖基化,而Fc的N末端第11个氨基酸苏氨酸残基(AEPKSCDKTHTCP…)也可以被糖基化。
代表性糖基团包括但不局限于:甘油、单糖、二糖、三糖、寡糖和多糖如淀粉、糖原、纤维素和/或多糖树胶。特别的单糖包括C6及以上(特别是C6和C8)糖如葡萄糖、果糖、甘露糖、半乳糖、核酸糖或景天庚糖;二糖和三糖包括含有二或三个单糖单元(特别是C5至C8)的基团、例如蔗糖、纤维二糖、麦芽糖、乳糖和/或蜜三糖。
其它亲水基团
生物适合的聚阳离子基团包括骨架或侧链上具有多个氨基的聚胺基团,例如聚赖氨酸和其它天然或合成的氨基酸构成的具有多个正电荷的氨基酸聚合物,包括聚鸟氨酸,聚精氨酸,聚组氨酸,非多肽聚胺如聚氨基苯乙烯,聚氨基丙烯酸酯,聚-N甲基氨基丙烯酸酯,季胺聚合物等。生物适合的聚阴离子基团包括骨架或侧链上具有多个羧基的基团,如聚天冬氨酸,聚谷氨酸等。其它亲水基团包括天然或合成多糖,如壳聚糖、葡聚糖等。
聚阴离子生物粘附剂
某些亲水基团有潜在的生物粘附特性。这样的例子可见于美国专利US 6,197,346。这些具有多个羧基的聚合物显示生物粘附特性。降解时显露出多个羧基的快速生物降解聚合物,如乳酸羟基乙酸共聚物(poly(lactide-co-glycolide))、聚酐、聚原酸酯也都是生物粘附剂。这些聚合物可以把多肽或蛋白药物投放到胃肠道。聚合物降解时暴露出来的羧基可以牢固附着在胃肠道,协助投放多肽或蛋白药物。
亲脂性基团
在一个实施例中,修饰基团包括一个或多个亲脂性基团。亲脂性基团可以是本领域人员众所周知的,包括但不限于:烷基、链烯基、炔基、芳基、芳基烷基、烷基芳香基、脂肪酸、胆甾醇以及亲脂性多聚物和低聚物。
烃基可以是饱和、非饱和、直链的、支链的或环烃,具有一个或多个碳原子。在一个实施例中,烃基有1、2、3、4、5、6、7、8、9、10、11、12、13、14、15、16、17、18、19、20、21、22、23、24、25、26、27、28、29、30或更多的碳原子。烃基可以是无取代,或有一个或者多个取代基。
亲脂性基团也可以是脂肪酸,如天然的、合成的、饱和的、不饱和的、直链的或支链的脂肪酸。在一个实施例中,脂肪酸有2、3、4、5、6、7、8、9、10、11、12、13、14、15、16、17、18、19、20、21、22、23、24或更多个碳原子。
结合策略
蛋白与修饰基团的结合程度、结合点的选择、修饰基团的选择要根据需要而变化,例如使缀合物在体内不易降解,从而延长血浆半衰期。结合部位可能包括一个氨基酸残基,比如赖氨酸残基。在一个实施例中,蛋白缀合物是单结合物。在另一个实施例中,蛋白缀合物是多结合物。在另一个实施例中,蛋白缀合物是单结合物、双结合物、三结合物、四结合物等的混合物。修饰基团可以相同,也可以不同。当蛋白缀合物具有多个修饰基团时,一个或多个修饰基团最好通过可水解键与融合蛋白相连而其它一个或多个修饰基团最好通过不可水解键与融合蛋白相连。或者所有修饰基团都通过可水解键与融合蛋白相连,但各个修饰基团在体内的水解速率有快有慢。
理想的结合策略是使缀合物具有原蛋白部分或全部生物活性。优选的胰岛素受体结合多肽的结合部位包括双链胰岛素类似物的B1-N末端、B链C末端原有或取代、插入后引入的赖氨酸侧链氨基或半胱氨酸侧链巯基、A链C末端取代或插入后引入的赖氨酸侧链氨基或半胱氨酸侧链巯基、单链胰岛素类似物的N末端或C末端原有或取代、插入后引入的赖氨酸侧链氨基或半胱氨酸侧链巯基。B1单结合物和B链双结合物是最常用的。另外可以通过在单链胰岛素类似物的C肽连接片段或A链、B链嵌入具有氨基或巯基的天然或非天然氨基酸来创造其它结合位点。白介素-1受体结合多肽最常用的结合位点包括84和116位的半胱氨酸侧链巯基或N末端的氨基。GLP-1类似物的最常用的结合位点包括GLP-1(7-37)-OH或GLP-1(7-36)-NH2从N末端起第10位、20位和28位原有或取代、插入后引入的赖氨酸侧链氨基或半胱氨酸侧链巯基,或C末端取代或插入后引入的赖氨酸侧链氨基或半胱氨酸侧链巯基。Exendin-4类似物的最常用的结合位点包括Exendin-4从N末端起第12位、20位、27位、28位、32位原有、取代或插入后引入的赖氨酸侧链氨基或半胱氨酸侧链巯基,或C末端取代或插入的赖氨酸侧链氨基或半胱氨酸侧链巯基。
修饰基团与蛋白可以通过可水解键(如酯,碳酸,可水解氨基甲酸酯)结合。可水解键使蛋白缀合物具有前药的效果。比如修饰基团的结合部位在蛋白对受体结合区,因此修饰基团与蛋白缀合物没有活性。当一个或多个修饰基团在一段时间内从蛋白缀合物脱离后,释放出活性蛋白。使用可水解键能够提供延时释放或缓释的效果。
在一个实施例中,蛋白通过非水解键(如酰胺键,醚键)与修饰基团相连。必要时,非水解键有助于延长蛋白缀合物在血浆中的循环时间。
蛋白或其类似物、衍生物可以通过各种亲核官能团与修饰基团相连,包括但不局限于亲核羟基或氨基。例如,丝氨酸、苏氨酸、酪氨酸具有亲核羟基,组氨酸、赖氨酸或胰岛素及其类似物的A链、B链N-末端都具有亲核氨基。胰岛素及其类似物也可以通过自由巯基-SH与修饰基团相连,例如形成硫酯、硫醚、磺胺键。
分子量较小的多肽或蛋白化合物在血浆中的循环时间短的一个重要因素就是肾清除。增加多肽或蛋白化合物分子量直至超过40,000道尔顿(Da)这个肾清除临界点,可以显著降低肾清除率,延长多肽在体内作用时间。常用的方法是使多肽或蛋白与天然或合成大分子形成可水解或不可水解键。生物大分子包括白蛋白、多糖(如葡聚糖)、抗体(如IgG)等。白蛋白和IgG占血浆蛋白的90%,有长达几周的体内循环时间。与白蛋白或IgG Fc结合的多肽的体内循环时间也可以显著延长。例如,etanercept就是可溶性TNF2受体结合IgG1Fc的产物。这个150kDa的受体二聚物是一种有效的抗炎物质,每周给药两次(t1/2=102小时)。近期批准的促进血小板生成的romiplostim是IgG融合蛋白的另外一个例子。
白蛋白可以是人白蛋白(HSA)、人白蛋白类似物或人白蛋白的一部分。人白蛋白包含585个氨基酸残基,分子量66500。EP322,094提供了较短的人白蛋白序列,包括HAS(1-373)、HAS(1-388)、HAS(1-389)、HAS(1-369)、HAS(1-419)以及1-369和1-419之间的片段。EP399666提供的序列包括HAS(1-177)、HAS(1-200)以及HSA(1-177)和HAS(1-200)之间的片段。免疫球蛋白的Fc部分可以是人免疫球蛋白的Fc部分、人免疫球蛋白Fc部分的类似物、人免疫球蛋白Fc部分的片段等。Fc可以包括铰链区、CH2、CH3直到C末端。Fc融合蛋白延长体内循环时间的一个主要因素是Fc能够结合FcRn。FcRn分布在内皮细胞的表面,以pH依赖的方式与IgG结合,保护IgG不被降解。在CH2和CH3界面的变异可以延长IgG的半衰期(Hinton PR等,2004.Engineered human IgG antibodies with longer serum half-lives inprimates.J Biol Chem.279(8):6213-6;Vaccaro C.等,2005.Engineering the Fcregion of immunoglobulin G to modulate in vivo antibody levels.NatBiotechnol.23(10):1283-8)。血管中70%的白蛋白是巯基白蛋白(mercaptalbumin),其半胱氨酸-34的侧链巯基是血浆中活性最强的巯基。本发明的蛋白或其类似物、衍生物可以通过一个一端带有马来酰亚胺等活化官能团的连接基与其反应生成融合蛋白-白蛋白缀合物。在一种实施方式中,本发明的蛋白的N-末端或C-末端可以与白蛋白或免疫球蛋白Fc的N-末端或C-末端相连。这种结合策略使小分子量化合物的循环时间达到其结合的血浆蛋白的半衰期,但代价可能是降低的受体结合能力。解决方案之一就是在多肽(或蛋白)与修饰基团之间插入间隔基。间隔基例如β-丙氨酸、γ-氨基丁酸、γ-谷氨酸或聚乙二醇可以用于多肽/蛋白的一个氨基和一个修饰基团之间。Liraglutide的棕榈酸基团(plamitoylgroup)通过一个间隔基与赖氨酸的侧链相连。另外的一个解决办法就是修饰基团通过一个“可逆”(“reversible”)连接基与多肽/蛋白相连。
融合蛋白/二聚蛋白/交联蛋白
本发明中涉及的融合蛋白、二聚蛋白或交联蛋白是GLP-1受体结合多肽、GIP受体结合多肽或胰岛素受体结合多肽与白介素-1受体拮抗蛋白的连接后的产物。两部分多肽/蛋白可以直接相连,也可以通过连接基(或间隔基)相连。融合蛋白/二聚蛋白/交联蛋白可以对白介素-1受体有IL-1RA的1%、5%、10%、20%、30%、40%、50%、60%、70%、80%、90%、100%或更高的生物活性,同时,根据另一部分是GLP-1受体结合多肽、GIP受体结合多肽或胰岛素受体结合多肽,对GLP-1受体、GIP受体或胰岛素受体分别有GLP-1(7-36)-NH2、GIP(1-42)或人胰岛素的0.1%、0.2%、0.3%、0.4%、0.5%、1%、5%、10%、20%、30%、40%、50%、60%、70%、80%、90%、100%或更高的生物活性。
本发明中的融合蛋白、二聚蛋白、交联蛋白及其衍生物可以使用生物工程技术制备和生产。为了蛋白表达和生产的便利,甲硫氨酸可以根据需要添加到本发明中各蛋白序列的N末端。
连接基(或间隔基)可以是化学合成的分子,如长链脂肪酸或聚乙二醇,也可以是天然或非天然氨基酸(如赖氨酸、谷氨酸、天冬氨酸)、短肽(如β-丙氨酸-β-丙氨酸)、蛋白,或一个或多个可选的长链脂肪酸、聚乙二醇、氨基酸、短肽等通过共价键连接而成的长链,或任何将两个活性多肽/蛋白通过共价键连接的结构,或缺失。
连接基可以通过化学反应连接两个原不相连接的多肽/蛋白(一个是白介素-1受体拮抗蛋白,另外一个是GLP-1受体结合多肽、GIP受体结合多肽或胰岛素受体结合多肽)。在一种实施方式中,连接基可以有2个反应基团(例如N-羟基琥珀酰亚胺(NHS酯)或马来酰亚胺),分别与白介素-1受体拮抗蛋白和GLP-1受体结合多肽(或GIP受体结合多肽或胰岛素受体结合多肽)上的氨基或巯基反应,使三个片段连为一体。在一种实施方式中,连接基可以有一个反应基团(例如NHS酯、马来酰亚胺、碘代乙酰基或乙烯砜)和一个功能基团(例如氨基或巯基),分别与白介素-1受体拮抗蛋白和GLP-1受体结合多肽(或GIP受体结合多肽或胰岛素受体结合多肽)上的另外一个功能基团(氨基或巯基)和另外一个反应基团(例如NHS酯、马来酰亚胺、碘代乙酰基或乙烯砜)反应,使三个片段连为一体。在另一种实施方式中,连接基可以有两个功能基团(例如氨基或巯基),分别与白介素-1受体拮抗蛋白和GLP-1受体结合多肽(或GIP受体结合多肽或胰岛素受体结合多肽)上的反应基团(例如NHS、马来酰亚胺、碘代乙酰基或乙烯砜)反应,使三个片段连为一体。反应基团和功能基团位于哪个片段,需要根据具体反应的要求而定。
如果连接基已经与一个具有生物活性的多肽(例如白介素-1受体拮抗蛋白)相连,而要通过化学反应连接另外一个原不相连接的具有生物活性的多肽,反应方式与上述类似。与一个多肽相连的连接基和另一个不相连的多肽一个需要有功能基团(例如氨基或巯基),另外一个需要有反应基团(例如NHS酯、马来酰亚胺、碘代乙酰基或乙烯砜)。至于反应基团和功能基团位于连接基或是多肽,需要根据具体反应的要求而定。

适用的连接片段CL具有三点特征:第一,连接片段需要适当的长度。当B链为30个氨基酸全长时,连接片段长度最好不少于6个氨基酸;当B链为25个氨基酸时,连接片段长度最好不少于10个氨基酸。连接片段长度过长或过短(短于上述氨基酸数目,或者长于60个氨基酸)时,单链类似物的胰岛素受体结合能力有降低趋势。第二,连接片段最好没有二级结构,空间构象可以灵活变化。第三,连接片段本身没有生物活性,但可以提供多肽修饰位点,如酰化、糖基化等。
该连接片段CL可以包含1个或1个以上天冬氨酸、谷氨酸、精氨酸、赖氨酸、半胱氨酸或天冬酰胺。CL可以包括1、2、3、4个天冬氨酸、谷氨酸、精氨酸或赖氨酸以调节多肽序列的电荷平衡,改善溶解度。该序列可以包括1、2、3、4、5个天冬酰胺和相同数量的丝氨酸或苏氨酸,从而组成构成N糖基化所需的N-X-S/T共有序列(X为可编码的天然氨基酸)。进一步地,该肽还可以包含1、2、3或4个赖氨酸或半胱氨酸,其侧链氨基或巯基可以与脂肪酸、聚乙二醇、白蛋白等天然或合成的修饰基团通过水解键或非水解键相连,从而使修饰后的胰岛素类似物具有不同的物理、化学和生物特性。

胰岛素受体结合多肽和白介素-1受体拮抗蛋白能够通过相似或不同的机理保护胰岛β细胞,治疗糖尿病。因此,将两种多肽连接后形成的融合蛋白可以通过两种多肽的协同作用,达到比单独使用其中一种多肽更优异的治疗效果。另外,胰岛素受体的主要分布组织及周边的炎症往往是糖尿病发病的原因之一。胰岛素受体结合多肽可以为融合蛋白起到靶向作用,使白介素-1受体拮抗蛋白富集于这些组织,更有效地发挥消炎等作用。
胰岛素受体结合多肽和白介素-1受体拮抗蛋白通过可选的连接基(或间隔基)相连,有多种连接方式。
(1)胰岛素受体结合多肽与白介素-1受体拮抗蛋白的连接方式为(从左到右对应氨基酸序列从N末端到C末端):

GIP受体结合多肽和白介素-1受体拮抗蛋白能够通过相似或不同的机理保护胰岛β细胞,治疗糖尿病。因此,将两种化合物连接后形成的融合蛋白、二聚蛋白或交接蛋白可以通过两种化合物的协同作用,达到比单独使用其中一种化合物更优异的治疗效果。另外,GIP受体的一个主要分布组织就是胰岛。GIP受体结合多肽可以为融合蛋白、二聚蛋白或交接蛋白起到靶向作用,使白介素-1受体拮抗蛋白富集于胰岛及胰岛周围,更有效地发挥消炎等作用。
GIP受体结合多肽与白介素-1受体拮抗蛋白通过可选的连接基(或间隔基)相连,可以有多种不同的连接方式。

多肽化学合成方法
线性多肽使用Boc固相多肽合成法或Fmoc固相多肽合成法。如果使用Fmoc化学合成C-末端是羧基的多肽,选用Wang树脂;C-末端是酰胺的多肽选用Rink amide树脂。如果使用Boc化学合成C-末端是羧基的多肽,选用Pam树脂;C-末端是酰胺的多肽选用MBHA树脂。缩合剂和活化剂是DIC和HOBT,其他可选肽键缩合剂包括BOP、HBTU、DEPBT等。氨基酸5倍过量。缩合时间为1小时。
Fmoc保护基用50%哌啶/DMF脱除。Boc保护基用TFA脱除。肽键缩合反应用茚三酮(Ninhydrin,2,2-Dihydroxyindane-1,3-dione)试剂监测。
使用Fmoc固相多肽合成法时,通用氨基酸及保护基如下:
Fmoc-Cys(Trt)-OH、Fmoc-Asp(OtBu)-OH、Fmoc-Glu(OtBu)-OH、Fmoc-His(Trt)-OH、Fmoc-Lys(Boc)-OH、Fmoc-Asn(Trt)-OH、Fmoc-Gln(Trt)-OH、Fmoc-Arg(Pmc)-OH、Fmoc-Ser(tBu)-OH、Fmoc-Thr(tBu)-OH、Boc-Trp(Boc)-OH或Fmoc-Tyr(tBu)-OH。
如果赖氨酸的侧链氨基用于酰化反应,赖氨酸的侧链氨基可以使用烯丙氧羰基(aloc)保护。肽链合成完毕,脱除烯丙氧羰基可以用四(三苯基膦)钯(0)和37:2:1比例的DCM、冰醋酸和NMM(15mL/g树脂)在氩气环境,室温条件下搅拌2小时。反应后树脂需要用0.5%DIPEA/DMF(10mL),0.5%三水合二乙基二硫代碳酸钠/DMF(3X10mL),1:1DCM:DMF(5X10mL)清洗。赖氨酸的侧链氨基也可以使用4-甲基三苯甲基(Mtt)。树脂悬浮于DCM,加入TFA/TIS/DCM(1:2:97),震荡10分钟。重复2遍后,树脂用DCM,DMF和异丙醇洗涤。
固相Fmoc化学合成多肽后,常用的切割试剂是TFA。将干树脂放在一个摇瓶中,加入适当量TFA/TIS/H2O(95:2.5:2.5,10-25mL/g树脂),盖上盖子,在室温下进行间歇式旋转震荡。2小时后抽滤树脂,以新的TFA清洗树脂2-3次,合并滤液,滴加8-10倍体积的冰乙醚。最后,离心收集沉淀出来的多肽粗品。
使用Boc固相多肽合成法时,通用氨基酸和保护基如下:Boc-Cys(4-MeBzl)-OH、Boc-Asp(OcHx)-OH、Boc-Glu(OcHx)-OH、Boc-His(Bom)-OH、Boc-Lys(2-Cl-Z)-OH,Boc-Asn(Xan)-OH、Boc-Arg(Tos)-OH、Boc-Ser(Bzl)-OH、Boc-Thr(Bzl)-OH、Boc-Trp(CHO)-OH和Boc-Tyr(2-Br-Z)-OH。
如果赖氨酸的侧链氨基用于合成内酰胺或酰化反应,赖氨酸的侧链氨基可以使用烯丙氧羰基(aloc)保护或Fmoc保护。如果天冬氨酸或谷氨酸的侧链羧基用于内酰胺合成或酰化反应,羧基应该转化为烯丙酯或9-芴基甲基保护。
固相Boc化学合成多肽后,对于PAM,MBHA树脂,一般采用HF切割,每0.1毫摩尔树脂加5毫升HF,同时加入对甲苯酚、对巯基苯酚或苯甲醚等试剂,混合物在冰浴条件下搅拌1小时。HF真空抽干后,多肽用冰乙醚沉淀,离心收集沉淀,经过HPLC分离纯化,冷冻干燥得到最后产品。

参照文献(“Interleukin-1receptor antagonist activity of a humaninterleukin-1inhibitor”,Hannum等,Nature 343,336-340)。简述如下:标准量的比放射性强度(specific Activity)为4000Ci/mmol的35S-标记的IL-1Ra加入96孔板,最终浓度约等于其Kd(150pM)。小鼠EL4胸腺瘤细胞(ATCC,TIB181,每个细胞约5000个受体)或表达人IL-1受体的中国仓鼠卵巢细胞(每个细胞约30,000个受体)和不同浓度的融合蛋白(从20mM到20pM系列稀释)在4℃培养4小时。细胞用Millipore millititer plate过滤系统收获。保留在过滤膜上的放射性用Ambis radioanalytical imaging system计量。野生型活性的百分比定义为IC50(野生型)/IC50(融合蛋白)。野生型IL-1ra的Kd用Cheng-Prusoffrelationship的简化模式估算(Kd=IC50/2),范围在150-400pM,与以前的文献报道一致。
2.胰岛素受体结合分析
(1)125I-胰岛素的制备
文献方法(Cresto等,“Preparation of biologically active mono-125I-insulin of high specific activity”,Acta Physiol Lat Am.1981,31(1):13-24)
(2)化合物的受体结合分析
文献方法(E.K.Frandsen and R.A.Bacchus.“New,simple insulin-receptorassay with universal application to solubilized insulin receptors andreceptors in broken and intact cells.”Diabetes,1987,36,3:335-340)或下述方法之一。如无特别说明,受体制备方法亦如文献方法,使用人胎盘膜。一般情况下,胰岛素受体结合实验使用0.025毫克胎盘膜。
在胰岛素受体结合分析实验中,胰岛素标准的起始浓度和本发明融合蛋白的起始浓度均为100nM,然后将胰岛素和融合蛋白系列3倍稀释,分别得到7个不同浓度的溶液(100nM、33.33nM、11.11nM、3.70nM、1.23nM、0.41nM、0.13nM、0.04nM)。对于本发明中在胰岛素受体的活性低于人胰岛素标准10%的融合蛋白,蛋白起始浓度为500nM。
截断的水溶性受体
胰岛素受体、125I-胰岛素(3pM)和系列3倍稀释的融合蛋白加入缓冲液[100mMHepes,pH 8.0,100mM NaCl,10mM MgCl2,0.5%(w/v)BSA,0.025%(w/v)Triton X-100],总体积200μL,在4℃培养48小时。受体及与受体结合的融合蛋白和配体用0.2%γ-球蛋白和500μL 25%(w/v)PEG 8000沉淀,测量沉淀中的放射性。受体的浓度要调节到在未添加融合蛋白的时候有15-20%的受体与配体结合。
膜结合受体
受体结合分析使用的膜结合受体来自高度表达全长胰岛素受体的BHK细胞。等量的转染BHK细胞(2000-5000)均匀分布在96孔板的每一孔,在包含10%(v/v)胎牛血清的Dulbecco's改良的Eagle's培养基(DMEM)中培养24小时后再进行受体结合分析。细胞先用结合缓冲液(DMEM,含0.50%BSA,20mM Hepes,pH 7.8)洗一遍,加入125I-胰岛素(6.5pM)和溶于结合缓冲液的系列3倍稀释的融合蛋白。在16℃培养3小时,未结合的多肽用吸引器吸出,用1.2ml结合缓冲液洗一遍。细胞溶解于500μL 1%(w/v)SDS,100mM NaCl,25mM Hepes(pH 7.8),然后测量。细胞数量要调整到未加融合蛋白时有16-28%的受体与配体结合。
胰岛素受体:125I-胰岛素(30nCi)、系列3倍稀释的融合蛋白和胎盘膜(0.025mg)在0.05毫升上述缓冲液中,20℃培养1小时。样品用EHWP过滤器过滤,培养管和过滤器用2.5毫升不含牛白蛋白的冷缓冲液洗4遍。没有胎盘膜的情况下,少于5%的融合蛋白附着在过滤器上。对胎盘膜非特异结合可以通过添加过量的非碘化胰岛素(1μM)到培养混合物来测量。非特异结合通常占配体与胎盘膜结合总量的1%以下。
特异结合百分比=(结合放射量-非特异结合放射量/全部结合放射量-非特异结合放射量)x100。全部结合放射量是未添加融合蛋白时测得的放射总量。结合放射量是添加融合蛋白后测得的放射量。融合蛋白的IC50使用Origin软件(OriginLab,Northampton,MA)计算。融合蛋白相对于人胰岛素标准的活性=IC50人胰岛素标准/IC50融合蛋白。
3.GLP-1cAMP分析
表达人胰岛GLP-1受体的BHK(baby hamster kidney)细胞按文献准备(Knudsen和Pridal,1996,Eur.J.Pharm.318,429-435)。质膜按文献准备(Adelhorst等,1994,J.Biol.Chem.269,6275),在缓冲液(10mmol/l Tris-HCl、30mmol/l NaCl,pH 7.4、1mmolDTT、5mg/l亮抑酶肽、5mg/l抑肽素、100mg/l杆菌肽素、16mg/l抑蛋白酶肽)中均化,均匀混合物在一层41w/v%蔗糖上离心。两层之间的白色条带溶解在缓冲液中离心,质膜保存在-80℃。
分析使用96孔微量滴定板,总体积140μl。缓冲液包含50mmol/l Tris-HCl,pH7.4、1mmol/l EGTA、1.5mmol/l MgSO4、1.7mmol/l ATP、20mM GTP、2mmol/l,3-异丁基-1-甲基黄嘌呤、0.01%吐温-20、0.1%人血清白蛋白。被测样品用缓冲液溶解和稀释,加到膜配制中。混合物在37°培养2小时。反应通过添加25μl 0.05mol/l HCl终止。样品稀释10倍后用亲近闪烁检测法(Scintillation Proximity Assay,SPA)测量cAMP。参考文献(Kahl等,“Scintillation Proximity Assay.”February,2005。DOI:10.1002/0471142301.ns0715s30。https://www.currentprotocols.com/WileyCDA/CPUnit/refId-ns0715.html)。
GLP-1(7-37)标准物的EC50是61pM。
4.GIP cAMP分析
根据文献方法(Wheeler等,“Characterization of the carboxyl-terminaldomain of the rat glucose-dependent insulinotropic polypeptide(GIP)receptor:arole for serines 426 and 427 in internalization”J.Biol.Chem.1999,274:24593-24601)。稳定表达GIP受体的CHO细胞转移到96孔微量滴定板,培养48小时。细胞用37℃的HEPES-缓冲的分析缓冲液液(DMEM/F12,15mM HEPES(Sigma-Aldrich),0.1%牛白蛋白(Sigma-Aldrich),pH 7.4)洗涤,预先培养60分钟。在细胞中加入样品(0.001~100nM融合蛋白,溶于10mM HEPES,pH 7.4、150mM NaCl、5mM KCl、2.5mM CaCl2、1.2mM KH2PO4、1.2mMMgSO4、25mM NaHCO3、0.5mM 3-异丁基-1-甲基黄嘌呤和1%(w/v)牛白蛋白)培育30分钟。对于GIP受体拮抗剂,细胞先与培育15分钟,然后加入1nM GIP(1-42)培育30分钟。cAMP量用亲近闪烁检测法测量。
5.GIP受体结合分析
GIP(5μg)以传统的氯胺-T方法碘化并用C-18柱纯化(Sep-Pak;MilliporeCorp.),乙腈梯度是30–45%。放射性标记的GIP的比放射性强度(specific Activity)为10–50μCi/mg。125I-GIP溶于分析缓冲液,浓度为3×105cpm/100μl。表达GIP受体的CHO细胞(1-5×105/孔)用结合缓冲液(DMEM/F12,20mm HEPES、0.1%牛白蛋白、0.5mg/ml杆菌肽素,pH7.4)洗两遍。加入125I-GIP(50000cpm)和0.3–500nM融合蛋白,在4℃培养12-16小时。未与受体结合的125I-GIP用真空分离。微量滴定板用冰冷的含有0.1%(w/v)牛白蛋白的PBS冲洗,在室温干燥。根据情况可以加入30μl Ultima Gold(Perkin-Elmer),用γ射线计数器测量125I-GIP含量。IC50计算方法参见胰岛素受体结合分析。GIP(1-42)标准的IC50是2.1±0.75nM。
实验结果:
通过对本发明的化合物进行GLP-1受体结合力、胰岛素受体结合力、GIP受体结合力和白介素-1受体结合力实验来检测这些化合物的生物活性,使用人GLP-1(7-37)作为GLP-1受体结合力的基准(100%)、人胰岛素作为胰岛素受体结合力的基准(100%)、GIP(1-42)作为GIP受体结合力的基准(100%)和野生型人IL-1Ra作为白介素-1受体拮抗蛋白的基准(100%)。得到的结果分别见表一、表二和表三。

注:表中GI-1~GI-5、GI-11~GI-15、GI-22、GI-24、GI-25、GI-27~GI-29使用cAMP试验。其它蛋白使用GIP受体结合分析试验,在括号中表示的是蛋白在GIP受体结合分析试验中的活性与GIP(1-42)的比值。这些蛋白对GIP受体是抑制剂,因此使用受体结合试验而不是cAMP试验。
动物试验
1、对五周龄C57BL/6J小鼠喂食高脂肪/高蔗糖饲料(其中卡路里58%来自脂肪、26%来自碳水化合物、16%来自蛋白)。小鼠分为四组,每组6只。试验一组每日腹腔内注射生理盐水(0.9%w/v,NaCl),试验二组每日注射IL-1Ra(500nmol/kg),试验三组、四组每日注射融合蛋白G-2和G-20(50nmol/kg),连续12周,随后进行葡萄糖耐量试验。小鼠先禁食12小时,然后腹腔内注射葡萄糖(2mg/g),在0、15、30、60、90、120分钟采集血液,测量血糖。另外,在0和30分钟测量血清胰岛素水平。
在图7所示试验中,IL-Ra组与生理盐水组相比,显示出更好的控制血糖的效果。而G-2和G-20组的小鼠的糖耐量明显增强,不仅血糖高峰低,而且血糖下降速度快。在12周治疗过程中,G-2和G-20的用量仅为IL-1Ra的1/10,表明GLP-1受体结合多肽与白介素-1受体拮抗蛋白的融合蛋白在体内生物活性和治疗效果都显著优于IL-1Ra。
在图8所示试验中,IL-Ra组的空腹血清胰岛素水平明显低于生理盐水组。生理盐水组在糖耐量试验过程中胰岛素水平变化很小,而IL-1Ra组的胰岛素水平是空腹时的2倍。G-2和G-20组的空腹血清胰岛素水平最低,而在糖耐量试验过程中胰岛素水平达到空腹时的2.5-4倍,显示G-2和G-20对胰岛功能的调节、保护作用优于单独使用IL-1Ra。显示出更好的控制血糖的效果。
2、对五周龄C57BL/6J小鼠喂食高脂肪/高蔗糖饲料(其中卡路里58%来自脂肪、26%来自碳水化合物、16%来自蛋白)。小鼠分为四组,每组6只。试验一组(对照组)每日腹腔内注射生理盐水(0.9%w/v,NaCl),试验二组每日注射IL-1Ra(500nmol/kg),试验三组、四组每日餐后注射融合蛋白IN-7和IN-62(30nmol/kg),连续12周,随后进行胰岛素耐量试验。小鼠先禁食5小时,然后腹腔内注射人胰岛素(0.75U/kg),在0、15、30、60、90、120分钟采集血液,测量血糖。
高脂肪食物往往导致高胰岛素血症,造成对胰岛素的敏感性下降,这是很大一部分肥胖的2型糖尿病患者的发病原因。提高胰岛素敏感性是预防甚至治疗糖尿病的重要方法之一。在图9所示试验中,IL-Ra组与生理盐水组相比,显示出较好的胰岛素敏感性。GI-3和GI-7组的小鼠的胰岛素敏感性更优异。在12周治疗过程中,IN-7和IN-62的用量仅为IL-1Ra的1/17,表明胰岛素与白介素-1受体拮抗蛋白的融合蛋白在体内生物活性和治疗效果都显著优于IL-1Ra。
3、对五周龄C57BL/6J小鼠喂食高脂肪/高蔗糖饲料(其中卡路里58%来自脂肪、26%来自碳水化合物、16%来自蛋白)。小鼠分为四组,每组6只。试验一组(对照组)每日腹腔内注射生理盐水(0.9%w/v,NaCl),试验二组每日注射IL-1Ra(500nmol/kg),试验三组、四组每日注射融合蛋白GI-3和GI-7(50nmol/kg),连续12周,随后进行葡萄糖耐量试验。小鼠先禁食12小时,然后腹腔内注射葡萄糖(2mg/g),在0、15、30、60分钟采集血液,测量血糖。
在图10所示试验中,IL-Ra组与对照生理盐水组相比,显示出更好的控制血糖的效果。而GI-3和GI-7组的小鼠的糖耐量明显增强,血糖高峰低。在12周治疗过程中,G-2和G-20的用量仅为IL-1Ra的1/10,表明GIP受体结合多肽与白介素-1受体拮抗蛋白的融合蛋白在体内生物活性和治疗效果都显著优于IL-1Ra。
上述试验中的融合蛋白在各自相应的受体测试中(表一、二、三)并不一定优于标准蛋白(IL-1Ra、GLP(7-37)、人胰岛素、GIP(1-42)),但融合蛋白通过其组成的两种蛋白/多肽的协同作用,在体内表现出更优异的生物活性和治疗效果,证明了融合蛋白的设计和制备方法的正确性。本发明中的融合蛋白有希望作为一类新型化合物应用于糖尿病的预防与治疗。
