previous work, a series of furan derivatives featuring alkyl-substituted phenols and 6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline were designed and synthesized as reversal agents against P-gp in this paper. Compound 16 containing isopropoxy possessed good potency against P-gp mediated MDR in MCF-7/ADR (IC50 (doxorubicin) = 0.73 μM, RF = 69.6 with 5 μM 16 treated).

P-糖蛋白(P-gp)介导的多药耐药性(MDR)是一种现象,其中细胞对结构和机械无关的药物产生耐药性,导致细胞内药物浓度低。这是恶性肿瘤临床治疗中值得注意的问题之一。因此,P-gp蛋白是解决MDR的理想目标之一。基于从我们先前的工作获得的铅化合物5m,设计并合成了一系列具有烷基取代的酚和6,7-二甲氧基-1,2,3,4-四氢异喹啉的呋喃衍生物,作为针对P-gp的逆转剂这篇报告。化合物16含有异丙具有良好的效力针对介导的多药耐药的P-gp MCF-7 / ADR(IC 50(阿霉素)= 0.73μM,RF = 69.6用5μM 16已处理)。Western印迹结果和Rh123积累测定表明16种有效抑制P-gp外排功能,但不抑制其表达。初步的结构-活性关系和对接研究表明,化合物16将是潜在的P-gp抑制剂。最值得一提的是,化合物16与多种抗肿瘤药物(如阿霉素,紫杉醇和长春新碱)合用已取得令人满
