The synthesis and biological evaluation of a novel series of compounds based on suberoylanilide hydroxamic acid (SAHA) had been designed as potential histone deacetylase inhibitors (HDACis). Molecular docking studies indicated that our derivatives had better fitting in the binding sites of HDAC8 than SAHA. Compounds 1–5 were synthesized through the synthetic routes. In biological test, compounds also
已经设计了一系列基于辛二酰苯胺异羟肟酸(SAHA)的新型化合物的合成和生物学评估,作为潜在的组蛋白脱乙酰基酶抑制剂(HDACis)。分子对接研究表明,我们的衍生物比SAHA具有更好的HDAC8结合位点。化合物1-5是通过合成途径合成的。在生物学测试中,化合物在HDAC酶分析中也显示出良好的抑制活性,并且在人神经胶质瘤细胞系(MGR2,U251和U373)中表现出更强的生长抑制作用。有代表性的化合物,N3F,表现出更好的抑制效果(HDAC,IC 50 = 0.1187 μ米; U251,IC 50 = 0.8949 μ米)和人正常细胞毒性较低(LO2,IC 50 = 172.5 μ米和MRC5,IC 50 = 213.6 μ米与SAHA(HDAC,IC相比)50 = 0.8717 μ米; U251,IC 50 = 8.938 μ米; LO2 ,IC 50 = 86.52
