This study reports the design, synthesis and evaluation of a series of histone deacetylase (HDAC) inhibitors containing purine/purine isoster as a capping group and an N-(2-aminophenyl)-benzamide unit. In vitro cytotoxicity studies reveal that benzamide 14 suppressed the growth of triple-negative breast cancer cells MDA-MB-231 (IC50 = 1.48 μM), MDA-MB-468 (IC50 = 0.65 μM), and liver cancer cells HepG2
这项研究报告了一系列组蛋白脱乙酰基酶(HDAC)抑制剂的设计,合成和评估,该抑制剂含有嘌呤/嘌呤等位基因作为封端基团和N-(2-氨基苯基)-苯甲酰胺单元。体外细胞毒性研究表明,苯甲酰胺14抑制三阴性乳腺癌细胞MDA-MB-231(IC50 = 1.48μM),MDA-MB-468(IC50 = 0.65μM)和肝癌细胞HepG2(IC50 = 2.44μM),优于MS-275(5)和Chidamide(6)。与著名的HDAC抑制剂SAHA相比,14种在三种白血病细胞系K-562,KG-1和THP-1中显示出更高的毒性(IC50 = 0.33μM)。此外,发现14在HDAC敏感和耐药胃细胞系YCC11和YCC3 / 7中分别具有同等毒性,表明14有克服HDACi耐药性的潜力。此外,14个化合物对HDAC1、2和3个亚型表现出比MS-275(5)和Chidamide(6)更显着的抑制作用,IC50值分别为0
