  In the present study, a total of 25 novel ningalin B analogues were synthesized and evaluated for their P-gp modulating activity in a P-gp overexpressed breast cancer cell line LCC6MDR. Preliminary structure-activity study shows that A ring and its two methoxy groups are important pharmacophores for P-gp inhibiting activity. Among all derivatives, 23 is the most potent P-gp modulator with EC50 of 120–165 nM

  在本研究中，总共合成了25种新的宁格灵B类似物，并评估了它们在过表达P-gp的乳腺癌细胞LCC6MDR中的P-gp调节活性。初步的结构活性研究表明，A环及其两个甲氧基是抑制P-gp活性的重要药效团。在所有衍生物中，23是最有效的P-gp调节剂，在逆转紫杉醇，DOX，长春碱和长春新碱的抗性方面，EC 50为120-165 nM。与维拉帕米相比，选择指数至少大于606相对安全。机理研究表明，化合物23通过抑制P-gp的转运活性来逆转P-gp介导的耐药性，从而恢复细胞内药物的积累。总而言之，我们的研究表明，宁格灵B类似物23是一种无细胞毒性且有效的P-gp化学增敏剂，可在将来用于逆转P-gp介导的临床癌症药物耐药性。
