Inhibition of histone deacetylases (HDACs) has been an important emerging therapy for the treatment of multiple cancers. However, the application of HDAC inhibitors is restricted by the limited potency against solid tumors. In order to discover novel HDAC inhibitors with potent antitumor activities, nitrogen mustard group was introduced to the structure of CI994. The derived molecule N-(2-aminophe
组蛋白脱乙酰酶(HDAC)的抑制已成为治疗多种癌症的重要新兴疗法。然而,HDAC抑制剂的应用因对抗实体瘤的效力有限而受到限制。为了发现具有有效抗肿瘤活性的新型HDAC抑制剂,在CI994的结构中引入了氮芥基团。衍生分子 N-(2-氨基苯基)-4-(双(2-氯乙基)氨基)苯甲酰胺 (NA) 对 HDAC1、HDAC2、和HDAC3,分别。在抗增殖测定中,NA 对 A2780 和 HepG2 细胞生长的抑制作用分别比辛二酰苯胺异羟肟酸 (SAHA)(27.3 和 19.5 μM)高 10.3 倍(2.66 μM)和 11.3 倍(1.73 μM)。进一步基于 HepG2 细胞的细胞周期和细胞凋亡研究表明,诱导 G2/M 期停滞和细胞凋亡有助于 NA 的抗肿瘤作用。建议NA可以作为先导化合物来开发用于治疗实体瘤的双功能HDAC抑制剂。
