Description
本申请要求申请日为2021年4月30日的中国申请CN202110485677.9的优先权。本申请引用上述中国申请的全文。
本发明涉及药物化学领域,更具体而言,涉及具有Wee-1激酶抑制作用的化合物、及其制备方法和该类化合物在抗肿瘤药物制备中的用途。
Wee-1蛋白激酶是细胞周期检查点中重要的负调控蛋白。细胞周期检查点包括G1(细胞静息期)到S期(DNA合成期)转变的G1期检查点,G2(细胞分裂准备期)到M(细胞分裂期)期转变的G2期检查点以及M期metaphase(细胞分裂期中期)到anaphase(细胞分裂期后期)转变的纺锤体检查点。Wee-1蛋白激酶在G2期检查点中发挥了重要的作用。细胞进入M期依赖于CDK1激酶活性,Wee-1通过磷酸化CDK1蛋白的Tyr 15,抑制CDK1的活性,阻止细胞进入M期(细胞分裂期)。而Polo kinase激酶磷酸化Wee-1,激活Wee-1蛋白的降解,促进细胞进入M期。由此可见,Wee-1激酶活性决定了G2检查点的活性,进而调节细胞G2到M期的转变。
细胞周期检查点主要在DNA损伤后激活,对细胞中DNA的修复发挥了重要作用。细胞周期检查点的正常激活阻滞细胞周期促进DNA修复。抑制检查点的功能,DNA损伤无法修复,细胞发生凋亡。与正常细胞相比,多种肿瘤细胞由于G1期检查点重要蛋白p53蛋白的功能受损,主要依赖于G2期检查点的激活修复DNA损伤,规避凋亡。因此,抑制G2期检查点,可以选择性的杀伤肿瘤细胞。而Wee-1激酶活性在G2期检查点中的重要作用,提示Wee-1激酶决定了DNA损伤后肿瘤细胞的修复或死亡,抑制Wee-1活性可以促进DNA损伤后未修复的肿瘤细胞进入M期,诱发凋亡。
研究表明,除了在G2检查点中的作用以外,Wee-1还参与了DNA合成,DNA同源修复,染色体组蛋白翻译后修饰等与肿瘤发生和发展密切相关的功能。在大量包括肝癌,乳腺癌,宫颈癌,黑色素瘤和肺癌等肿瘤中,Wee-1表达大大升高。而Wee-1的高表达与肿瘤的发展和预后较差成正相关,提示Wee-1激酶可能参与了肿瘤的发生和发展。体外细胞模型和体内动物模型的研究表明在诱发DNA损伤的同时抑制Wee-1活性能够显著抑制多种肿瘤的生长。
因此,开发特异性的高活性Wee-1激酶的小分子抑制剂对于肿瘤治疗,尤其是靶向诸如P53缺失的G1检查点受损的肿瘤具有重要的临床价值。
目前,AstraZeneca的Wee-1抑制剂AZD1775(MK-1775,Adavosertib)已进入临床2期研究阶段,有超过30项临床试验正在开发。与AZD1775相关的专利有US20070254892、WO2007126122、EP2213673、WO2008133866、WO2011034743等。Abbott和Abbvie对Wee-1抑制剂也展开过研究,相关专利主要有US2012220572、WO2013126656、WO2013012681、WO2013059485、WO2013013031等。Almac公司关于Wee-1抑制剂的专利包括WO2014167347、WO2015019037、WO2015092431、WO2018011570、WO2018062932、WO2019138227等。Girafpharma公司的Wee-1专利包括WO2019074979和WO2019074981。Zeno公司关于Wee-1研究的专利包括WO2018028008和WO2019173082。
研究中的Wee-1抑制剂仍然存在一些问题,单药的治疗效果较差,而和其它化疗药物联用的细胞活性也不够强,因此临床上联用效果也不够理想。靶向治疗到后期通常会产生耐药性,化疗成为晚期肿瘤治疗的常用手段,单用化疗药物治疗往往产生较大的副作用,病人耐受性差,因此发明和化疗药物具有很好联用效果的Wee-1抑制剂具有非常重要的意义。

化合物的进一步形式
“药学上可接受”这里指一种物质,如载体或稀释液,不会使化合物的生物活性或性质消失,且相对无毒,如,给予个体某物质,不会引起不想要的生物影响或以有害的方式与任何其含有的组分相互作用。
术语“药学上可接受的盐”指一种化合物的存在形式,该形式不会引起对给药有机体 的重要的刺激,且不会使化合物的生物活性和性质消失。在某些具体方面,药学上可接受的盐是通过通式(1)化合物与酸反应获得,如盐酸、氢溴酸、氢氟酸、硫酸、磷酸、硝酸、碳酸等无机酸,甲酸、乙酸、丙酸、草酸、三氟乙酸、丙二酸、琥珀酸、富马酸、马来酸、乳酸、苹果酸、酒石酸、柠檬酸、苦味酸、甲磺酸、苯磺酸、对甲苯磺酸等有机酸以及天冬氨酸、谷氨酸等酸性氨基酸。
应理解药学上可接受的盐的参考包括溶剂添加形式或结晶形式,尤其是溶剂化物或多晶型。溶剂化物含有化学计量或非化学计量的溶剂,且是在与药学上可接受溶剂如水,乙醇等,结晶化过程中选择性形成的。当溶剂是水时形成水合物,或当溶剂是乙醇时形成醇化物。通式(1)化合物的溶剂化物按照本文所述的方法,很方便的制得或形成。举例说明,通式(1)化合物的水合物从水/有机溶剂的混合溶剂中重结晶而方便的制得,使用的有机溶剂包括但不限于,四氢呋喃、丙酮、乙醇或甲醇。此外,在此提到的化合物能够以非溶剂化和溶剂化形式存在。总之,对于在此提供的化合物和方法为目的,溶剂化形式被认为相当于非溶剂化形式。
在其他具体实施例中,通式(1)化合物被制备成不同的形式,包括但不限于,无定形,粉碎形和毫微-粒度形式。此外,通式(1)化合物包括结晶型,也可以作为多晶型。多晶型包括化合物的相同元素组成的不同晶格排列。多晶型通常有不同的X-射线衍射光谱、红外光谱、熔点、密度、硬度、晶型、光和电的性质、稳定性和溶解性。不同的因素如重结晶溶剂,结晶速率和贮存温度可能引起单一晶型为主导。
在另一个方面,通式(1)化合物可能存在手性中心和/或轴手性,并因此以消旋体、外消旋混合物、单一对映体、非对映异构体化合物和单一非对映体的形式、和顺反异构体的形式出现。每个手性中心或轴手性将独立地产生两个旋光异构体,并且所有可能的旋光异构体和非对映体混合物以及纯或部分纯的化合物包括在本发明的范围之内。本发明意味着包括这些化合物的所有这种异构形式。
本发明的化合物可以在一个或多个构成该化合物的原子上包含非天然比例的原子同位素。例如,可用放射性同位素标记化合物,比如氚(
3H)、碘-125(
125I)和C-14(
14C)。又例如,可用重氢取代氢原子形成氘代化合物,氘与碳构成的键比普通氢和碳构成的键更坚固,相比于未氘代药物,通常氘代药物具有降低毒副作用、增加药物稳定性、增强疗效、延长药物体内半衰期等优势。本发明的化合物的所有同位素组成的变换,无论放射性与否,都包含在本发明的范围之内。

3000个/孔MIA PaCa-2细胞铺于384孔板并加入20nM Gemcitabine,过夜贴壁后,加入DMSO或者最高浓度为100nM,1:5梯度稀释的化合物。加药后72小时,通过测定细胞内ATP含量,评价细胞存活。与DMSO组相比,计算化合物抑制细胞存活的百分比,进而计算IC
50值,结果见下列表5。
表5本发明化合物单药或联合GMC对MIA PaCa-2细胞的抗增殖活性
从表5数据可见本发明化合物对MIA PaCa-2细胞都具有较强的抗增殖活性,如化合物1、化合物2、化合物7、化合物36和化合物42对MIA PaCa-2细胞的抗增殖活性IC
50小于100nM,与对照药物MK-1775相比,提高了10倍以上。特别是本发明化合物具有更强的和GMC联用活性,如化合物1、化合物2、化合物10、化合物12、化合物13、化合物32和化合物42的IC
50小于2nM。本发明化合物具有很强的和GMC联用活性,预示其在临床上和化疗药物联用可能具有更好的效果。
虽然以上描述了本发明的具体实施方式,但是本领域的技术人员应当理解,这些仅是举例说明,在不背离本发明的原理和实质的前提下,可以对这些实施方式做出多种变更或修改。因此,本发明的保护范围由所附权利要求书限定。
