Abstract
本发明提供了一类具有甲基转移酶抑制活性的化合物,具体地,本发明提供了一类具有PRMT5抑制活性的化合物。所述的化合物是可以被用于制备治疗PRMT5活性相关的疾病的药物组合物。
Description
技术领域
本发明涉及药物化合物领域,具体地,本发明提供了一类用于抑制PRMT5的化合物,及其用于药物组合物的用途。
背景技术
基因表达的表观遗传调控是蛋白质产生和细胞分化的重要生物学决定因素,在许多人类疾病中起着重要的致病作用。
表观遗传调控涉及遗传物质的可遗传修饰而不改变其核苷酸序列。通常,表观遗传调控由DNA和蛋白质(例如组蛋白)的选择性和可逆修饰(例如甲基化)介导,这些修饰控制染色质转录活性和非活性状态之间的构象转变。这些共价修饰可以由甲基转移酶(例如PRMT5)等酶控制,其中许多与可能导致人类疾病的特定遗传改变有关。PRMT5在增殖性疾病、代谢性疾病和血液疾病等疾病中发挥作用。
PRMT5是一种已知的细胞必需基因,条件性PRMT5敲除和siRNA敲除研究表明,正常组织中的PRMT5抑制与一系列疾病相关(例如,全血细胞减少症、不孕症、骨骼肌丧失、心脏肥大)。因此,需要新的策略来利用这种代谢脆弱性并优先针对MTAP无效肿瘤中的PRMT5,同时在正常组织中保留PRMT5(MTAPWT)。用MTA协同小分子抑制剂靶向PRMT5可以优先靶向PRMT5的MTA结合状态,富含MTAP无效肿瘤细胞,同时提供优于MTAP完整且MTA水平低的正常细胞的治疗指数。
因此,本领域需要提供新的靶向MTAP无效肿瘤中的PRMT5的小分子化合物。
