compounds have been evaluated against HepG2 cells (hepatoma cancer) for antiproliferative activity. Compounds that showed activity better or comparable to that of 3 versus HepG2 were evaluated against MCF-7 (breast cancer), MIA PaCa-2 (pancreatic cancer), and Bel-7402 (hepatoma/liver cancer) for antiproliferative activity. Of the seven compounds selected for further study five (13b, 13g, 13j, 13k and 13l)
当前对咔唑环上IG-105(3)的优化提供了一系列新的咔唑磺酰胺衍生物13a - 13m。所有化合物均已针对HepG2细胞(肝癌)进行了抗增殖活性评估。与MCP-7(乳腺癌),MIA PaCa-2(胰腺癌)和Bel-7402(肝癌/肝癌)相比,针对HepG2表现出更好或可与之媲美的3种化合物的抗增殖活性进行了评估。在选择用于进一步研究的七种化合物中,发现五种(13b,13g,13j,13k和13l)的IC 50为针对四种细胞系比得上值3。两种化合物(13f和13i)的活性高于3,并且它们对HepG2和MCF-7的活性(IC 50:0.01–0.07μM)接近阳性对照鬼臼毒素(podo)和CA-4。大多数化合物的水溶性(pH 7.4和2.0时为0.11–19.60μg/ mL)优于3。这些有希望的结果保证了作为潜在的潜在抗肿瘤药物候选者的新化合物13f和13i的进一步开发。
