A novel series of ester and carbamate derivatives was synthesized and evaluated its activities against Leishmania amazonensis. All compounds exhibited weaker leishmanicidal activity than amphotericin B. However, results indicated that substituents on the aryl–acyl subunit are important for modulation of the leishmanicidal effect. The nitro derivative showed the highest activity of the series with an
合成了一系列新的酯和氨基甲酸酯衍生物,并评价了其对亚马逊利什曼原虫的活性。所有化合物均显示出比两性霉素B弱的杀螨活性。但是,结果表明,芳基-酰基亚基上的取代基对于调节杀螨效果很重要。硝基衍生物显示出该系列的最高活性,IC 50 = 17.24μM,并且具有与3,4-苯并二恶唑酯和氨基甲酸正己酯衍生物相当的效力。所有化合物对人细胞均显示低毒性。这些结果揭示了有趣的新颖胡椒碱样分子模式,可用于寻找和开发有效且低毒的抗衰老药物候选药物。
