Chemotherapy of leishmaniasis. Part XII: Design, synthesis and bioevaluation of novel triazole integrated phenyl heteroterpenoids as antileishmanial agents
A novel series of triazole integrated phenyl heteroterpenoids have been synthesized and screened for their in vitro activity against intracellular amastigote form of Leishmania donovani. Among all tested compounds, compound 3a was found to be the most active with IC50 6.4 μM and better selectivity index (SI) 18 as compared to reference drugs, miltefosine and miconazole. When evaluated in vivo in L
合成了一系列新的三唑结合的苯基杂环化合物,并筛选了其对利什曼原虫胞内鞭炮形式的体外活性。在所有测试化合物中,发现化合物3a与参考药物miltefosine和miconazole相比,活性最高,IC 50为6.4μM,选择性指数(SI)为18。当在多诺氏乳杆菌/仓鼠模型中进行体内评估时,在 治疗后第7天,在50 mg kg -1 ×5天时,3a表现出对寄生虫繁殖的抑制79±11%。
