In this study, new marine ningalin B analogues containing a piperazine or a benzoloxy group at ring C have been synthesized and evaluated on their P-gp modulating activity in human breast cancer and leukemia cell lines. Their structure-activity relationship was preliminarily studied. Compounds 19 and 20 are potent P-gp inhibitors. These two synthetic analogues of permethyl ningalin B may be potentially used as effective modulators of P-gp-mediated drug resistance in cancer cells.
在本研究中,已合成了在C环含有哌嗪或苯甲氧基的新型海洋宁加林B类似物,并在人乳腺癌和白血病细胞系中评估了它们对P-糖蛋白的调节活性。初步研究了它们的构效关系。化合物19和20是有效的P-糖蛋白抑制剂。这两种全甲基化宁加林B的合成类似物可能潜在地用作癌细胞中P-糖蛋白介导的耐药性的有效调节剂。
