endogenous levels of retinoic acid in the treatment of hyperproliferative disease. Here the synthesis and inhibitory activity of novel 3-(1H-imidazol- and triazol-1-yl)-2,2-dimethyl-3-(4-(phenylamino)phenyl)propyl derivatives in a MCF-7 CYP26A1 microsomal assay are described. The most promising inhibitor methyl 2,2-dimethyl-3-(4-(phenylamino)phenyl)-3-(1H-1,2,4-triazol-1-yl)propanoate (6) exhibited an
维甲酸(RA)是维生素A的生物活性代谢物,在医学上用于治疗过度增生性疾病,包括皮肤病和癌症。RA的抗增殖作用以及毒性和对RA治疗产生抗药性的局限性已得到充分证明。RA代谢抑制剂(RAMBAs或CYP26抑制剂)作为在过度增殖性疾病中增强内源性视黄酸水平的替代方法,引起了越来越多的关注。新型3-(1 H描述了在MCF-7 CYP26A1微粒体测定中的-咪唑-和三唑-1-基)-2,2-二甲基-3-(4-(苯基氨基)苯基)丙基衍生物。最有前途的抑制剂2,2-二甲基-3-(4-(苯基氨基)苯基)-3-(1 H -1,2,4-三唑-1-基)丙酸酯(6)的IC 50为13 nM(与标准Liarozole IC 50 540 nM和R116010 IC 50 10 nM相比),并使用一组CYP进一步评估CYP选择性,发现CYP26的选择性> 100倍,而观察到的CYP1A2、2C9和2D6则为15倍与C
