46 nM (KB-7D). Dual inhibitory potential of compound 9 was found as it demonstrated significant inhibitory potential against HDAC1, 2 and 6 in comparison to MS-275 (6). Some key interactions of 9 with the amino acid residues of the active site of tubulin and with amino acid residues of HDAC 1 isoform have been figured out by molecular modeling. Compound 9 also demonstrated significant in vivo efficacy in
我们报告基于1-芳基磺酰基
吲哚的苯甲酰胺的结构活性关系。苯甲酰胺(9)表现出显着的微管蛋白抑制作用,IC 50值为1.1μM,优于康培他汀A-4(3),并且对多种癌细胞具有显着的抗增殖活性,包括具有IC的MDR阳性
细胞系50值分别为49 nM(KB),79 nM(A549),63 nM(MKN45),64 nM(KB-VIN10),43 nM(KB-S15)和46 nM(KB-7D)。化合物的双重抑制潜力9被发现,因为它显示出在比较针对H
DAC1,2和6显著抑制潜力到MS-275(6)。9的一些关键交互通过分子建模已经找出了具有微管蛋白活性位点的
氨基酸残基和具有H
DAC 1同工型的
氨基酸残基的化合物。化合物9在人非小细胞肺癌A549异种移植模型以及B细胞淋巴瘤BJAB异种移植肿瘤模型中也显示出显着的体内功效。
