In the present study, a series of novel dual-target histone deacetylase (HDAC) and mammalian target of rapamycin (mTOR) inhibitors were designed and synthesized using pyrimidine-pyrazolyl pharmacophore to append HDAC recognition cap and hydroxamic acid as a zinc-binding motif. Among them, 12l was the optimal lead compound with potent inhibition activities against mTOR and HDAC1 with half-maximal inhibitory
在本研究中,设计并合成了一系列新型双靶组蛋白脱乙酰基酶(HDAC)和哺乳动物雷帕霉素靶(mTOR)抑制剂,并使用嘧啶-吡唑基药效团附加了HDAC识别帽和异羟肟酸作为锌结合基序。其中12l是对mTOR和HDAC1具有强抑制活性的最佳前导化合物,半数抑制浓度分别为1.2和0.19 nM。Western印迹证实12l可以上调H3和α-微管蛋白的乙酰化作用,并下调mTOR相关的下游介体。12l还可以刺激细胞周期停滞在G0 / G1期并诱导肿瘤细胞凋亡。12l在MM1S异种移植模型中显示出与联合用药相当的抗肿瘤活性,肿瘤生长抑制率为72.5%,而不会引起体重和毒性的显着下降。所有结果表明12l可能是治疗血液恶性肿瘤的有希望的双重靶标抑制剂。
