The 7-benzylidenenaltrexone (BNTX) derivatives 2a–v, 3a–c, 13a–c, and 14a were synthesized from naltrexone (1) and evaluated for their antitrichomonal activity. The structure-activity-relationship studies found that 4-iodo-BNTX (2g) showed the highest activity (IC50 = 10.5 µM) and the affinity for the opioid receptor was less important for antitrichomonal activity against Trichomonas vaginalis. The
从纳曲酮(1)合成了7-亚苄基纳曲酮(BNTX)衍生物2a–v,3a–c,13a–c和14a,并评估了其抗滴虫活性。结构-活性-关系研究发现,4-碘-BNTX(2g)表现出最高的活性(IC 50 = 10.5 µM),对阿片样物质受体的亲和力对阴道毛滴虫的抗滴虫活性的重要性较小。。带有迈克尔受体双键和酚羟基的吗啡喃骨架将是开发抗滴虫剂的特定模板。此外,BNTX衍生物的抗滴虫活性机制可能与标准药物甲硝唑不同。
