One-pot multicomponent synthesis of medicinally important purine quinazolinone derivatives
摘要:
Herein, a protocol that involves microwave-assisted, multicomponent one-pot synthetic strategy for the construction of the medicinally important purine quinazolinone scaffold is reported. A series of compounds are prepared by cyclization and condensation reactions using this approach. The compounds are structural analogs of anticancer agents IC-87114 and CAL-101, which are highly isoform-selective PI3K-delta inhibitors and are presently under clinical investigation for chronic lymphocytic leukemia.

A strategy for construction of medicinally important 1,4-substituted 1H-1,2,3-triazolo-quinazolin-4(3H)-ones has been devised and presented here. The compounds have been synthesized using one-pot multicomponent strategy under microwave assisted conditions. Triazolyl-quinazolinone based D-ring modified analogs are designed based on IC87114 scaffold, which is first known isoform selective inhibitor of
已经设计并提出了构建具有医学重要性的1,4-取代的1 H -1,2,3-三唑并喹唑啉-4(3 H)-ones的策略。这些化合物是在微波辅助条件下使用一锅多组分策略合成的。基于三唑基-喹唑啉酮的D环修饰类似物是基于IC87114支架设计的,该支架是第一个已知的PI3Kδ异构体选择性抑制剂。在本文中,我们基于具有PI3Kγ特异性抑制潜能的相同支架,鉴定了两种三唑基-喹唑啉酮化合物(5a和5l),对这种同工型的选择性得到了计算机模拟的充分支持结果,其中这些化合物对PI3Kγ的活性比对PI3Kδ的相互作用,亲和力和抑制活性更好。从药物化学和药物发现的角度来看,将支架从PI3Kδ转变为PI3Kγ亚型可能非常有用,可以阐明这种新支架在不同细胞途径中的分子相互作用。
