Starting with a lead [1,5-a]pyrimidin-7(4H)-one-containing molecule (1), we generated potent, selective and orally bioavailable KDM5 inhibitors. Using structure- and property-based approaches, we designed 48 with improved cell potency (PC9 H3K4Me3 EC50=0.34muM). Furthermore, 48 maintained suitable physiochemical properties and displayed an excellent pharmacokinetic (PK) profile in mice. When dosed
从含[1,5-a]嘧啶-7(4H)-一的先导分子(1)开始,我们生成了有效的,选择性的和口服可生物利用的KDM5抑制剂。使用基于结构和属性的方法,我们设计了48个具有改善的细胞效能的(PC9 H3K4Me3 EC50 =0.34μM)。此外,48维持适当的理化特性,并在小鼠中显示出出色的药代动力学(PK)档案。当每天两次以50mg / kg的剂量在小鼠中口服给药(BID)时,48的最大血浆浓度(Cmax)超过其细胞EC50的15倍,从而为研究KDM5体内生物学功能提供了强大的化学探针。
