Description

一种二氢吡啶并[2,3-d]嘧啶酮衍生物的盐、其制备方法及用途
本申请要求于2020年7月22日提交中国专利局、申请号为202010711260.5发明名称为“一种二氢吡啶并[2,3-d]嘧啶酮衍生物的盐、其制备方法及用途”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请属于药物化学领域,具体涉及一种二氢吡啶并[2,3-d]嘧啶酮衍生物的盐、其制备方法以及医药用途。
背景技术
磷脂酰肌醇3-激酶(PI3K)及其下游蛋白AKT(又称蛋白激酶B,PKB)和哺乳动物雷帕霉素靶蛋白(mTOR)组成的PI3K/AKT/mTOR通路作为细胞内非常重要的信号转导途径,在细胞的生长、存活、增殖、凋亡、血管生成、自吞噬等过程中发挥着极其重要的生物学功能。该通路的异常激活会引起一系列的疾病,包括癌症、神经病变、自身免疫性疾病和血液淋巴系统疾病。
AKT,是一类丝氨酸/苏氨酸激酶,通过下游众多效应器影响细胞存活、生长、代谢、增殖、迁移和分化。超过50%的人类肿瘤存在AKT过度活化的现象,尤以前列腺癌、胰腺癌、膀胱癌、卵巢癌、乳腺癌为主。AKT过活化可导致肿瘤发生、转移以及耐药性产生。
AKT具有三种亚型:AKT1、AKT2和AKT3。作为典型的蛋白激酶,每种亚型均由氨基末端的PH结构域(Pleckstrin homology domain)、中部结合ATP的激酶结构域以及羧基末端的调节结构域组成。3种亚型约80%的氨基酸序列同源,仅在PH结构域和激酶结构域连接区变化较大。
目前,针对PI3K/AKT/mTOR信号通路的靶向药物主要是PI3K抑制剂和mTOR抑制剂,而AKT处于该信号转导通路的核心部位。抑制AKT活性既可避免抑制上游PI3K造成的严重副作用,也可避免抑制下游mTOR引起的负反馈机制影响药效。例如,CN101631778A公开了一类环戊二烯并[D]嘧啶衍生物,CN101578273A公开了一类羟基化和甲氧基化的环戊二烯并[D]嘧啶衍生物,CN101511842A公开了一类二氢呋喃并嘧啶衍生物,CN101970415A公开了一类5H-环戊二烯并[d]嘧啶衍生物,这些化合物具有小于10μM的抑制AKT1的IC 50。然而,寻找有效和选择性的AKT抑制剂仍然是当前肿瘤靶向药物 研发的重要方向。
