against HDACs. The cytotoxicity was measured by SRB method. The enzyme inhibitory effects of the compounds were evaluated by the fluorescent assay. RESULTS Biological evaluation showed that these hydroxamic acids were generally cytotoxic against four human cancer cell lines (SW620, colon; PC-3, prostate; AsPC-1, pancreas; NCI-H23, lung). Several compounds, e.g. 7g, 11c, and 11g, displayed up to 10-fold
背景技术组蛋白脱乙酰基酶(HDAC)酶正在成为癌症治疗的潜在靶标。在这项研究中,探索了一系列新的异羟肟酸与1-(((1H-1,2,3-三唑-4-基)甲基)-3-取代-2-氧代二氢吲哚。方法使用Autodock Vina程序设计化合物,然后在体外和计算机模拟中合成和评估其对HDAC的抑制活性。通过SRB法测定细胞毒性。通过荧光测定评估了化合物的酶抑制作用。结果生物学评估表明,这些异羟肟酸通常对四种人类癌细胞系(SW620,结肠; PC-3,前列腺; AsPC-1,胰腺; NCI-H23,肺)具有细胞毒性。几种化合物,例如7g,11c和11g,在细胞毒性方面显示出比SAHA(亚磺酰苯胺异羟肟酸,伏立诺他)强10倍的功效。合成的化合物还具有相对于SAHA抑制HDAC2的作用。特别是,化合物11c对HDAC1,HDAC2,HDAC6和HDAC8表现出潜在的抑制作用,其效力与SAHA相当或略高。对四
