acrylamide derivatives with differently substituted indoles at the 3-position as the core scaffold were designed and synthesized. In addition, the actions of these compounds at the enzyme and cellular levels were evaluated. An MTT assay with different kinds of cells was used to assess the cytotoxic activities of compounds 14e and 14n, which displayed potent hIMPDH2 inhibitory activities (IC50 = 4.207
肌苷 5'-单磷酸脱氢酶 (IMPDH; EC1.1.1.205) 是 GMP 生物合成的限速酶。抑制 IMPDH 会限制肿瘤的生长和存活。在对临床IMPDH抑制剂进行系统总结的基础上,设计合成了38种以3位不同取代吲哚为核心支架的丙烯酰胺衍生物。此外,还评估了这些化合物在酶和细胞水平上的作用。使用不同种类细胞的 MTT 测定来评估化合物14e和14n的细胞毒活性,它们显示出有效的h IMPDH2 抑制活性(IC 50 = 4.207 和 2.948 μM,分别)。生物学评价表明目标化合物14e和14n对 SW480 人结肠癌细胞表现出最显着的作用(IC 50 分别 = 15.34 ± 0.06 和 15.31 ± 0.09 μM),并且确定这些化合物是有效且有价值的 IMPDH 抑制剂,可用于癌症干预。
