As a continuation of previous research, fifteen bifendate derivatives bearing 6,7-dihydro-dibenzo [c,e]azepine scaffold were synthesized and evaluated as P-gp-medicated multidrug resistance (MDR) reversal agents. Biological evaluation indicated that compounds 6k and 9c more potently reversed P-gp-mediated MDR than bifendate and verapamil (VRP) by blocking P-gp mediated drug efflux function and not
作为先前研究的延续,合成了15个带有6,7-二氢-二苯并[c,e]氮杂pine骨架的联苯菊酯衍生物,并将其评估为P-gp药物多药耐药性(MDR)逆转剂。生物学评估表明,化合物6k和9c通过阻止P-gp介导的药物外排功能,而不是通过降低K562 / A02 MDR细胞中P-gp的表达,比联苯菊酯和维拉帕米(VRP)更有效地逆转P-gp介导的MDR。有趣的是,伤口愈合和小室迁移分析表明6k和9c可以显着减弱MDA-MB-231细胞的迁移。值得注意的是6k和9c可以显着抑制MDA-MB-231细胞的侵袭活性,从而显示出潜在的抗转移活性。初步的机理研究表明,6k和9c的抗转移活性与其对MMP-2和MMP-9的活性和表达的抑制作用有关。这些结果以及MDR逆转结果表明,化合物6k和9c可能是开发具有P-gp和肿瘤转移抑制活性的新型抗癌药的有希望的先导。
