using estrogen receptor positive breast cancer cell lines MCF-7 and BT-474. Majority of the compounds exhibited activity against the p53-positive MCF-7 breast cancer cells but not against the p53-negative BT-474 breast cancer cells. Among forskolin derivatives, compounds 11a, 11c, 14a, 14f, 14g, 14h, 15b, 16g and 17b exhibited higher anti-cancer activity against MCF-7 cell line with an IC50 ≤ 1 µM. The
毛喉素Ç 1 -异恶唑衍生物(3,5-位置异构体)(11A - ë,14,15A - ħ和15,16A -克)通过采用1,3-偶极环加成区域选择性合成。使用雌激素受体阳性乳腺癌细胞系MCF-7和BT-474对这些衍生物进行了测试。大多数化合物对p53阳性MCF-7乳腺癌细胞显示活性,但对p53阴性BT-474乳腺癌细胞没有活性。在福斯高林衍生物中,化合物11a,11c,14a,14f,14g,14H,15B,16克和17B与IC表现出对MCF-7细胞系更高的抗癌活性50 ≤1μM。衍生物14f在p53阳性(MCF-7)和p53阴性(BT-474)乳腺癌细胞系中均表现出最高的活性,IC 50为0.5 µM。
