Abstract
本发明涉及一类杂代吡啶并嘧啶酮衍生物、及其作为治疗上有效的周期蛋白依赖性蛋白激酶(CDK)抑制剂的应用。具体的,本发明涉及一种通式(I)所示的新的杂代吡啶并嘧啶酮类衍生物、及其药物组合物,作为选择性CDK4/6抑制剂在预防或治疗与CDK4/6相关疾病中的用途。
Description
技术领域
本发明涉及药物制备技术领域,特别是涉及一种杂代吡啶并嘧啶酮衍生物作为CDK抑制剂及其应用。
背景技术
周期蛋白依赖性蛋白激酶(cyclin-dependent kinase,CDK)和周期蛋白(cyclin)是细胞周期调控中的重要因子。CDK可以和cyclin结合形成异二聚体,其中CDK为催化亚基,cyclin为调节亚基,形成各种cyclin-CDK复合物,使不同底物磷酸化,对细胞周期不同的时相起推进和转化作用。
在哺乳动物中至少存在9种CDK。细胞由G1期向S期转化主要受G1期CDK激酶控制。与G1期细胞周期蛋白(cyclin)结合的CDK激酶主要包括CDK2、CDK4和CKD6。Cyclin D主要与CDK4和CKD6结合并调节后者活性;cyclin E在G1/S期与CDK2结合,呈现CDK 2的激酶活性促进细胞进入S期。G2/M期主要受CDK1激酶调控,Cyclin A、CyclinB与CDK1结合,CDK1使底物蛋白磷酸化,如将组蛋白H1磷酸化则导致染色体凝缩,如将核纤层蛋白磷酸化则使核膜解体。在M期,M期促发因子(MPF)激活后期促进因子APC,将泛连接在Cyclin A和Cyclin B上,通过多泛素化作用,使它们被蛋白酶体降解,完成一个细胞周期(Malumbres M.etal.Nat Cell Biol 11:1275,2009;Malumbres M.etal.NatRev Cancer 9:153,2009)。
过去十年来,CDK抑制剂作为抗肿瘤新药开发为全球药业的一个热点,有超过20个CDK抑制剂进入临床开发。尽管CDK抑制剂抗肿瘤临床前药效学结果显著,但是早前多数临床试验结果不尽人意。主要问题包括在实体瘤缺乏疗效和毒性较大。(Guha M.Nat Rev Drug Dis11:892,2012)。而在分析产生严重毒副作用时发现,部分CDK抑制剂药物对CDK亚型缺乏选择性,因此产生了较大的毒副作用。
CDK4和CDK6是两个密切相关的激酶,在肿瘤细胞周期中与Cyclin D结合促使G1期进入S期,是DNA复制细胞分裂的细胞周期进程必需的。而超过90%的人类肿瘤中,均发现通过各种的基因和生化适应导致G1-S期的过渡控制机制改变。P16和人视网膜母细胞瘤抑制蛋白(retinoblastoma,Rb)是重要的肿痛抑制蛋白,其能调控细胞周期。P16基因蛋白抑制CDK4、Cyclin D1和Rb的反馈回路,并通过调节Rb的蛋白活性,从而防止细胞过度增殖,以达到抑制肿瘤的目的。已经证明在人体肿瘤中(如乳腺癌和骨髓瘤),CDK4和CDK6激活导致细胞周期改变发生。而抑制CDK4和CDK6,可阻止肿瘤抑制蛋白Rb的失活和干扰肿瘤细胞周期进展(Choi YJ and Anders L,Oncogene 33:1890-903,2014)。
由于CDK4/6在各种实体肿瘤和血液肿瘤的细胞周期控制失调中起关键作用。目前,选择性CDK4/6抑制剂目前有多个处于临床阶段(如Palbociclib、LY2835219和LEE011)。这些药物的临床评价还包括转移性乳腺癌、卵巢癌、脂肪肉瘤、非小细胞肺癌、肝癌、胶质母细胞瘤、黑素瘤、多发性骨髓瘤和淋巴瘤等。
虽然有许多CDK抑制剂类化合物已经被公开,但是,由于受CDK介导的病理的原因,仍然需要大量用于治疗与CDK有关的障碍的大量药物,特别是CDK4/6抑制类药物。
发明内容
