A series of derivatives were synthesized and studied with the aim to investigate the structure-activity relationships of the two P-glycoprotein (P-gp) modulators elacridar and tariquidar. Then, different aryl-substituted amides were inserted, and to explore the effects of varying the amide function, the corresponding isosteric ester derivatives and some alkylamine analogues were synthesized. The new
为了研究两种P-糖蛋白(P-gp)调节剂elacridar和tariquidar的结构-活性关系,合成并研究了一系列衍生物。然后,插入不同的芳基取代的酰胺,并探讨改变酰胺功能的影响,合成了相应的等位酯衍生物和一些烷基胺类似物。对新化合物进行了研究,以评估其与其他两种ABC转运蛋白(多药耐药相关蛋白1(MRP-1)和乳腺癌耐药蛋白(BCRP))的P-gp相互作用谱和选择性。对酰胺和酯衍生物对自发或酶促水解的化学稳定性的研究表明,这些化合物在磷酸盐缓冲液和人体血浆中稳定。这项研究使我们能够评估在三个外排泵上三个系列的选择性,并提出定义P-gp相互作用曲线的结构要求。我们确定了两种P-gp底物,一种P-gp抑制剂和三种对BCRP具有活性的酯衍生物,这为开发对该泵具有活性的配体开辟了新的前景。
