effects, which justify the efforts to find new antileishmanial drugs. Cinnamic acid derivatives have shown several pharmacological activities, including antiparasitic action. Therefore, in the present study, the biological evaluation of cinnamic acid and thirty-four derivatives against L. infantum is reported. The compounds were prepared by several synthesis methods and characterized by spectroscopic
婴儿利什曼原虫是南美洲、地中海盆地以及西亚和中亚的内脏利什曼病 (VL) 的病原体。受影响最严重的国家巴西在 2017 年报告了 4297 例 VL 病例。L. infantum 由雌性白蛉在连续吸血期间传播。没有经过验证的疫苗可以预防感染,治疗依赖于经常出现严重副作用的药物,这证明了寻找新的抗利什曼病药物的努力是合理的。肉桂酸衍生物已显示多种药理活性,包括抗寄生虫作用。因此,在本研究中,报道了肉桂酸和 34 种衍生物对婴儿乳杆菌的生物学评价。这些化合物是通过几种合成方法制备的,并通过光谱技术和高分辨率质谱法进行了表征。结果表明,化合物 32(N-(4-异丙基苄基)肉桂酰胺)是最有效的抗利什曼病药物(IC50 = 33.71 μM),选择性指数最高(SI > 42.46),其次是化合物 15(胡椒基肉桂酸酯),IC50 = 42.80 μM 和 SI > 32.86。与两性霉素 B 相比,化合物
