Using a rational design strategy for isoform-selective inhibition of PI3Kα, two series of novel 2,3,4,5-tetra-substituted thiophene derivatives containing either diaryl urea or N-Acylarylhydrazone scaffold were designed and synthesized. The most promising compound 12k was demonstrated to bear nanomolar PI3Kα inhibitory potency with 12, 28, 30, 196-fold selectivity against isoforms β, γ, δ and mTOR
使用合理的设计策略对
PI3Kα进行同工型选择性抑制,设计并合成了两个系列的新型二,3,4,5-四取代
噻吩衍
生物,它们既包含二芳基
尿素,也包含N-酰基芳基hydr骨架。事实证明,最有希望的化合物12k具有纳摩尔
PI3Kα抑制能力,对同工型β,γ,δ和mTOR具有12、28、30、196倍的选择性。此外,它在针对一组人类肿瘤细胞的细胞增殖以及A
DME分析中也显示出良好的可显影性。我们在此报告其设计,合成,
SAR和潜在的可开发性。
