inhibition of the zinc enzyme carbonic anhydrase (CA, EC 4.2.1.1). These coumarins were very weak or ineffective as inhibitors of the housekeeping, offtarget isoforms CA I and II, but some of them inhibited tumor-associated CA IX and XII in the low nanomolar range. They also significantly inhibited the growth of primary tumors by the highly aggressive 4T1 syngeneic mouse mammary tumor cells at 30 mg/kg, constituting
合成了一系列结合了各种糖基部分的7-取代香豆素,并研究了其对锌酶碳酸酐酶的抑制作用(CA,EC 4.2.1.1)。这些香豆素作为管家抑制剂,脱靶亚型CA I和II非常弱或无效,但其中一些在低纳摩尔范围内抑制与肿瘤相关的CA IX和XII。它们还以30 mg / kg的高侵袭性4T1同系小鼠乳腺肿瘤细胞显着抑制了原发性肿瘤的生长,构成了开发概念上新颖的抗癌药物的有趣候选物。由于CA IX在低氧性肿瘤中过表达,并且在正常组织中的表达非常有限,因此此类化合物可用于治疗对经典化学疗法和放射疗法无反应的癌症。
