Description
发明领域
本发明涉及2-取代的4-杂芳基-嘧啶,它们的制备,含有它们的药物组合物,及它们在治疗如癌症、白血病、牛皮癣等的增殖性疾病中的用途
背景技术
某些具有抗哮喘性能的4,5,6-取代的-N-(取代的苯基)-2-嘧啶被公开在EP-A-233,461。某些具有抗增殖性能和抑制蛋白激酶C的,结合表皮生长因子结合的4-杂芳基-N-(3-取代的苯基)-2-吡啶胺、结合表皮生长因子受体的酪氨酸蛋白激酶(EGF-R-TPK)、以及CDK1/细胞周期蛋白B已被公开在WO95/09847,其中杂芳基的例子均是吡啶基的吲哚基。
Paul,R.等人在J.Med.Chem.(1993)Vol.36,p2716-2725中还公开了一类具有抗炎活性的苯基氨基嘧啶。这些化合物包括在嘧啶环的4-位上有单取代的2-噻吩基团和在这位置上的二甲基-3-呋喃基团。
本发明的目的是要提供另一类N-苯基-2-嘧啶抗增殖性化合物。人们出于意料地发现,本发明化合物原来并不是蛋白激酶C抑制剂。正如下面所讨论的,它们的活性可以由它们能抑制细胞系的细胞增殖和/或抑制细胞周期蛋白依赖性激酶来证实。在统篇说明书中“噻吩基(thienyl)”与“噻吩(thiophene)”是互换使用的。

根据细胞测定显示,以下该化合物是更有效的抗增殖剂:[4-(2,4-二甲基-噻唑-5-基)-嘧啶-2-基]-(4-碘-苯基)-胺。
现已研究发现式I化合物具有抗增殖活性,因此它们被认为能用于治疗增殖性疾病,例如癌症、白血病和其它与非细胞控制性增殖有关的疾病,例如牛皮癣和再狭窄。如前面定义中所述,本发明化合物的抗增殖效果可通过以下两种途径来验证:在体外全细胞测定中,例如用A549、HT29、Saos-2、Hela或MCF-7的任一种细胞系测定抑制细胞增殖的能力;或者在某种专门的测定中可显示CDK酶(如CDK2或CDK4)的抑制作用。这些测定它们性能的方法在实施例23中作了较为详细的说明。使用这样的细胞系测定和酶测定,可以确定一种化合物是否本发明所述的抗增殖化合物。
虽然没有理论上的解释,但本发明化合物被认为是以非蛋白激酶C(PKC)依赖性的方式发挥它们的抗增殖作用。本发明这些化合物中有许多化合物对于与细胞系调节有关的细胞周期蛋白依赖性激酶的一些酶(CDKs)有抑制作用。这些CDKs包括CDK2和CDK4以及尤其是它们分别与细胞周期蛋白E和D1之间的相互作用。本发明的这些化合物还被确认为具有对于增殖性疾病中所含有的一些CDK酶是有选择性的优点。所谓“选择性”是指该化合物对其它酶(如PKC)虽然也有某种抑制作用,但其优选的是抵抗与增殖性疾病有关的酶。
本发明化合物可抑制细胞周期中的任何步骤或阶段,例如,细胞核外膜的形成、细胞周期退出非活性阶段(GO)、G1步态、染色体解凝聚、核外膜破损、细胞周期调控、DNA复制的引发、DNA复制的进程、DNA复制的终止、中心体重复、G2进程、有丝分裂或减数分裂功能的活化、染色体的凝聚、中心体分离、微管成核、纺锤体形成和功能的产生、与微管动力蛋白之间的相互作用、染色单体分离、有丝分裂功能的灭活、收缩环的形成、和胞质分裂功能的产生。特别是,本发明化合物可影响某些基因的功能,例如染色质的结合、复制复合体的形成、复制许可、磷酸化或其它次级修饰活性、蛋白水解、微管结合、肌动蛋白结合、浓毒性蛋白(septin)结合、微管结构中心成核活性以及与细胞周期信号途径中的组分结合。
因此本发明另一优选的实施方案是涉及式I的一种或多种化合物在治疗增殖性疾病中的用途。优选的是,该增殖性疾病是癌症或白血病。“增殖性疾病”这是一个广义词,它包括任何一种需要控制细胞周期的疾病,例如:心血管病如再狭窄和心脏病、自身免疫障碍如肾小球肾炎和风湿性关节炎、皮肤病如牛皮癣、抗炎性、抗真茵性、抗寄生性疾病如疟疾、气肿和脱发。在这些疾病中,本发明化合物可根据需要诱导细胞凋亡或停滞在所需的细胞内。
在一个特别优选的实施方案中,本发明涉及式I的一种或多种化合物在治疗CDK依赖性或敏感性疾病中的用途。CDK依赖性疾病关系到上述一种或多种CDK酶活性的正常水平。该疾病主要与CDK2和/或CDK4活性的非正常水平有关。CDK敏感性疾病是这样的一种病,其CDK水平的失常不是主要病因,而主要是代谢失常而代谢水平低下。在这样的情况下,CDK2和/或CDK4可被认为是部分的敏感性代谢的途径,因此CDK抑制剂可以有治疗这些疾病的活性。这些疾病主要是癌症或白血病。
本发明第二方面涉及下式I的一种或多种化合物及其药学上可接受的盐在制备用于治疗增殖性疾病的药物中的用途,
其中:
X1是CH和X2是S;或
X1和X2之一是S,而X1和X2之另一是N;
Z是NH,NHCO,NHSO2,NHCH2,CH2,CH2CH2,或CH=CH;
R1,R2,和R3各自是H,烷基,芳基,芳烷基,杂环基,卤素,NO2,CN,OH,烷氧基,芳氧基,NH2,NH-R’,N-(R’)(R”),NH-芳基,N-(芳基)2,COOH,COO-R’,COO-芳基,CONH2,CONH-R’,CON-(R’)(R”),CONH-芳基,CON-(芳基)2,SO3H,SO2NH2,CF3,CO-R’,或CO-芳基,其中烷基,芳基,芳烷基和杂环基团可以进一步被一个或多个选自卤素,NO2,CN,OH,O-甲基,NH2,COOH,CONH2和CF3的基团取代;
R4,R5,R6,R7,和R8各自是H,取代或不取代的低级烷基,卤素,NO2,CN,OH,取代或不取代的烷氧基,NH2,NH-R’,N-(R’)(R”),COOH,COO-R’,CONH2,CONH-R’,CON-(R’)(R”),SO3H,SO2NH2,或CF3,但除了当R5,R6和R7都是甲氧基以及R4和R8都是氢之外或者当R6和R7都是甲氧基以及R4,R5和R8都是氢之外;
其中R’和R”各自是烷基,它们可以相同或不同。
“增殖性疾病”的含义前面已经讨论,它与本发明第一方面所用的定义相同。
本发明这一方面的优选实施方案与上述第一方面的实施方案相同。
在一个特别优选的实施方案中,本发明的一种或多种化合物与一种或多种其它抗癌药联合施用。在此情况下,本发明的一种或多种化合物可与一种或多种其它抗癌药依次、同时、或连续地联合施用。
这里所用的短语“药物的制备”,除了它用在筛选抗癌药的程序中或在制备这种药的任一阶段之外还包括用式I化合物直接作为药物。
本发明化合物(第一和第二方面)可以盐或酯,特别是以药学上可接受的盐或酯的形式存在。
本发明化合物的药学上可接受的盐(第一和第二方面)包括其适当的酸加成盐或碱式盐。合适的药用盐可见Berge等人在J Pharm Sci,
66,1-19(1977)中的综述。用以下的酸形成盐,例如,用强无机酸如硫酸、磷酸或盐酸等的无机酸;用强有机羧酸如未取代或取代的(如卤代)1-4碳原子的烷羧酸如乙酸;用饱和或不饱和的二羧酸如草酸、丙二酸、琥珀酸、马来酸、富马酸、邻苯二甲酸或均苯四甲酸;用羟基羧酸如抗坏血酸、乙醇酸、乳酸、苹果酸、酒石酸、或柠檬酸;用氨基酸如天冬氨酸或谷氨酸;用苯甲酸;或用有机磺酸如未取代或取代(例如卤代)的(C1-C4)-烷基-或芳基-磺酸例如甲磺酸或对甲苯磺酸。
酯是用有机酸或用醇/氢氧化物形成的,取决于被酯化的官能基。所用的有机酸包括羧酸,例如未取代或取代的(如卤代)1-12碳原子的烷羧酸如乙酸;饱和或不饱和的二羧酸如草酸、丙二酸、琥珀酸、马来酸、富马酸、邻苯二甲酸或均苯四甲酸;羟基羧酸如抗坏血酸、乙醇酸、乳酸、苹果酸、酒石酸、或柠檬酸;氨基酸如天冬氨酸或谷氨酸;苯甲酸;或者有机磺酸如未取代或取代的(例如卤代)(C1-C4)-烷基-或芳基磺酸例如甲磺酸或对甲苯磺酸。合适的氢氧化物包括无机氢氧化物,例如氢氧化钾、氢氧化钠、氢氧化钙、氢氧化铝。醇包括1-12碳原子的烷醇,可以是未取代的或取代的(如卤代)。
在前面讨论的本发明的所有方面中,在适当情况下本发明包括式I化合物的所有的对映异构体和互变异构体。本领域技术人员会识别所有具有光学性能(一个或多个手性碳原子)或互变异构特征的化合物。这些相应的对映体和/或互变异构体可以用本领域已知的方法制备。
本发明还涉及各种结晶形式、多晶形式和无定型形式的本发明(第一和第二方面)化合物或它们的用途。通过稍改变一下从合成制备这些化合物时所用的溶剂中纯化或分离的方法,可以将化合物分离成这些形式中的任何一种形式,在制药工业中已较完善地建立了这样的方法。
本发明还包括前药形式的本发明化合物(第一和第二方面)或它们的用途。这些前药通常是式I中的一个或多个适当的基团已被修饰的化合物,而该修饰在人体或动物体服药后是可以逆转的。这种逆转通常是通过体内天然存在的酶进行的,虽然与这种前药一起服用第二种药使体内进行这种逆转也是可能的。这种修饰物的例子包括酯(例如,上述的任一种酯),其中可进行该逆转的是酯酶等的物质。其它的体系的物质是本领域技术人员众所周知的。
本发明也包括含有本发明化合物(第一和第二方面)的药物组合物。关于这一点,尤其是对人的治疗来说,本发明化合物(包括它们的药学上可接受的盐、酯和药学上可接受的溶剂化物)即使能被单独服用,但通常也总是与根据用药途径和标准的用药实践所选择的药用载体、赋型剂或稀释剂一起混合服用。
因此,本发明也涉及含有式I的一种或多种化合物或其药学上可接受的盐或酯与至少一种药学上可接受的赋型剂、稀释剂或载体一起的药物组合物。
作为举例,在本发明的药物化合物中,本发明的化合物可以与任何一种或多种合适的粘结剂、润滑剂、混悬剂、包衣剂、和/或增溶剂混合。适合于这里所述的各种不同剂型药物组合物的赋型剂的例子可以在Wade和PJWeller出版的“药物赋型剂手册”第2版(1994)中找到。
本发明的药物组合物可采用口服、直肠、阴道、肠胃外、肌肉、腹膜内、动脉内、鞘内、支气管内、皮下、皮内、静脉内、鼻、向颊或舌下的途径给药。
对于口服来说,具体的是使用压制的片剂、小丸、凝胶、滴剂、和胶囊。组合物中活性成分的含量优选为每剂1-250mg,更优选为10-100mg。
其它给药剂型有:溶液或乳液,它们可以是静脉内、动脉内、鞘内、皮下、皮内、腹膜内或肌内注射的,它们可从无菌的或灭菌的溶液制备。本发明的药物组合物也可以是栓剂、阴道栓剂、混悬剂、乳剂、洗剂、软膏、霜膏、凝胶、喷雾剂、溶液或粉剂的形式。
另一种透皮给药的方式是用皮肤贴剂。例如,可将活性成分掺入由聚乙二醇或液体石蜡的含水乳液组成的膏剂中。该活性成分也可按1-10%重量浓度将其掺到由白腊或白色的软石腊与可要求使用的稳定剂和防腐剂一起组成的软膏中。
注射剂型中可含10-1000mg,优选10-250mg/每剂的活性组分。
组合物可以配制成单剂量形式,即每一份含单位剂量的形式,或者多剂量或小剂量的单位剂型。
本领域技术人员很容易确定给患者服用适当剂量的某种组合物而无需做任何试验。通常,医生确定的对某一患者最合适的实际剂量可根据年龄、体重和反应的不同而变化。本发明所公开的剂量例子是各种情况的平均值。对于个别情况当然要考虑更高的剂量或更低的剂量,这些也应当属于本发明的范围。
在典型的实施方案中,对于治疗恶性肿瘤来说,将给患者服用每天一剂或多剂的10-150mg。
本发明的药物给合物还可含有一种或多种另外抗癌药,例如在市场上现成有售的抗癌药。
几种抗癌药联合施用通常更为有效。尤其是为了避免多重的主要毒性作用机理和抗药性机理,需要进行联合疗法。而且,大多数药物需要在每次剂量之间最短的时间间隔里以最大的耐受剂量服用。几种化疗药物联合施用的主要优点是它可以通过生物化学的反应来促进加倍的或协同的作用,并且也可降低早期肿瘤细胞中耐药性的恢复,而这些肿瘤细胞对起初用单一药物化疗已经有了反应。在选择联合用药中利用生物化学反应的例子是服用亚叶酸来提高5-氟尿嘧啶的活性胞内代谢物与它的靶物即胸苷酸合酶的结合能力,从而提高它的胞毒作用。
最近,治疗癌症和白血病使用了许多联合用药的方法。医学实践中对此的更深入的评述可见Springer出版的E.E.Vokes和H.M.Golomb编的“肿瘤治疗”。
对于某一种特定的初期癌症或由该癌症衍生的细胞系的治疗是用一些已知的或尚不能确定是否有效的药物来对受试化合物产生抑制活性进行研究,通过该研究可以提出一些有效的联合用药方案。这种方法也能被用来确定几种药物传送的次序是先、后还是同时给药。这样的时间上安排可能是本发明鉴定所有药物轮流发生作用的一个特点。
可以与至少一种本发明化合物联合用药的合适的抗增殖剂包括:DNA破坏剂、抗代谢药、抗肿瘤的抗生素、天然产物或它们的类似物、二氢叶酸还原酶、嘧啶类似物、嘌呤类似物、细胞周期蛋白依赖性激酶抑制剂、胸苷酸合酶抑制剂、DNA螯合剂、DNA剪切剂、拓朴异构酶抑制剂、氨茴环霉素、长春花属药物、丝裂霉素、博来霉素、细胞毒素核苷、蝶啶类药物、二炔烯(diynenes)、足叶草毒素、含铂药物、分化诱发剂、和taxans。这些类别中特别有用的成员包括,例如,氨甲蝶呤、二氯蝶呤、二氯氨甲蝶呤、5-氟尿嘧啶、6-巯嘌呤、三取代的嘌呤如olomoucine、roscovitine、bohemine和purvalanol、flavopiridol、staurosporin、阿糖胞苷、美洁仑、环氧长春碱、放线菌素、柔红霉素、阿霉素、丝裂霉素D、mitomycin A、caminomycin、氨基喋呤、fallysomycin、足叶草毒素(及其衍生物)、足叶乙甙、顺铂、carboplatinum、长春(花)碱、长春新碱、长春碱酰胺、paclitaxel、docetaxel、taxotere retinoic acid、butyric acid、乙酰精脒、他莫昔芬、innotecan和喜树碱。该药物部分最优选的是选自氨甲蝶呤、足叶草毒素(及其衍生物)、足叶乙甙、喜树碱、paclitaxel、阿霉素、roscovitine和bohemine。
本发明的化合物是能合成的,例如可用Traube合成法(A.R.Katritzky,I.Taher,Can.J.Chem.1986,64,2087,这里引用的参考文献),也即,如以下反应示意图中所示,通过1,3-羰基化合物1或者丙烯酸酯2或3,与脒4之间的缩合反应可以合成本发明的化合物。
反应式1
其中二羰基化合物1可用许多现有技术中已知的方法制备(J.March,In:Advanced Organic Chemistry:Reactions,Mechanism,and Structure,4th Ed.,John Wiley & Sons,Inc.,New York,1992,p.1283)。适用于本发明目的的具体的丙烯酸酯2和3可从杂环甲酮5通过其分别与二甲基甲酰胺二甲基乙缩醛6和醛7缩合而制得,(反应式2)。
反应式2
根据通式结构中Z的定义,二氨基化合物4将是脒4a或胍4b。脒(HN=CRNH2)可以从容易得到的胺前体通过与例如烯酮亚胺缩合或者通过氨与合适的腈或亚胺酯(imidates)加成而得到。胍4b(反应式3)能用现有技术中已知的许多方法精制而成。对于本发明目的而言,最有用的途径是氨腈8与苯胺9的胺化方法。
反应式3
或者,通式I化合物也可从适当的嘧啶前体直接得到,例如从2,4-二取代的(卤素、胺等)嘧啶通过逐位取代反应而制得。以下参考附图举例进一步说明本发明。

下列实验表明了某些化合物诱导人肿瘤细胞中的细胞周期停滞和细胞程序死亡的能力实施例25 在人肿瘤细胞中有丝分裂停滞和细胞程序死亡的诱导
人的骨肉瘤细胞(Saos-2)用1μM的化合物28处理48h。用相差显微镜(图1)观察有丝分裂细胞的积累和细胞程序死亡的出现。化合物28诱发的有丝分裂细胞的积累用有丝分裂指数的HitKit(Cellomix)进一步加以定量。实施例26
用有丝分裂指数的HitKit(Cellomix)研究了化合物28对有丝分裂指数的影响。用长春花碱作为实验的对照。按丝分裂指数的HitKit中的指示来制备A549细胞的板,得到的结果在图3和4中表示。实施例27
图5表示化合物28对有丝分裂指数的影响。图5中的数据是在每一孔的6个场中所观察到的,它们表明了受试化合物对于有丝分裂细胞的百分数的影响。化合物28使该有丝分裂细胞百分数从在未处理孔中样品的2.6%(未表示出数据)提高到在4.4μM浓度时的最大值17%。在这个浓度以上观察到有丝分裂细胞数量增加,这与细胞总数增加有关。这表明了发生了毒性,也表明了这些细胞正在从板底脱离。长春花碱在22nM浓度下使有丝分裂细胞百分数增加到31%同时在此浓度以上又出现了毒性。实施例28
除了诱发细胞程序死亡之外,本发明的某些化合物能使诱导编程性细胞死亡的形式易于从形态学的标准上与细胞程序死亡加以区别。化合物28以细胞质空胞化为特征的诱导编程性细胞死亡表示在图6。将人的肺癌细胞(A549)用10μM的化合物28处理16h。在经过处理的细胞(A)中观察到大范围的细胞质空胞化现象,而在对照细胞(B)中没有观察到。
