resistant cancers (MDR) and attendant resensitization to chemotherapeutic agents represent a promising strategy for treating cancer. We have synthesized four novel pentacyclic Strychnos alkaloids alstolucines B (2), F (3), and A (5) and N-demethylalstogucine (4), in addition to known Strychnos alkaloid echitamidine (16), and we evaluated compounds 1–5 in biochemical assays with ABCC10 and P-glycoprotein
在多药耐药性癌症(MDR)中过表达的ATP结合盒(ABC)外排泵的选择性调节以及随之而来的对化学治疗剂的重新敏化代表了一种有前途的治疗癌症的策略。我们已合成了4和新颖五环马钱子生物碱alstolucines B(2),F(3)和A(5)和Ñ -demethylalstogucine(4)中,除了已知的马钱子生物碱echitamidine(16),和我们评估化合物1 - 5用ABCC10和P-糖蛋白(P-gp)进行生化分析。Alstolucines B(2)和F(3)在12.5μM时抑制ABCC10 ATPase活性,而不会影响P-gp功能;此外,他们将转染了ABCC10的细胞系对10μM的紫杉醇进行了敏化。总而言之,在用于过表达该泵的MDR癌症的ABCC10调节剂的开发中,总醛糖是有希望的主要候选药物。
