New 2-aminobenzamide-type histone deacetylase (HDAC) inhibitors were synthesized. They feature a sulfur-containing bicyclic arylmethyl moiety—a surface recognition domain introduced to increase in cellular uptake—and a substituted tert-amino group which affects physicochemical properties such as aqueous solubility. Compound 22 with a (2-hydroxyethyl)(4-(thiophen-2-yl)benzyl)amino group reduced the
合成了新型的2-氨基苯甲酰胺型组蛋白脱乙酰基酶(HDAC)抑制剂。它们具有含硫的双环芳基甲基部分(一种引入表面识别结构域以增加细胞摄取的功能)和取代的叔氨基基团,其影响物理化学性质(如水溶性)。具有(2-羟乙基)(4-(噻吩-2-基)苄基)氨基的化合物22通过以45 mg / kg的口服剂量将裸鼠中人结肠癌HCT116异种移植的体积降低至T / C 67%,与阳性对照MS-275的比率(T / C 62%)相当。Western blot分析以及通过流式细胞术进行的细胞周期和TUNEL分析表明,这两种化合物通过相似的机制抑制癌细胞的生长。
