halomethylated choline analogs (series III). Assessments of their in vitro cytotoxicity in human promonocytic cells U-937 and antileishmanial activity in axenic amastigotes of L. (Viannia) panamensis (M/HOM/87/UA140-pIR-eGFP) were carried out using the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide) micromethod. Antileishmanial activity was also tested in intracellular amastigotes of L. (V) panamensis
这项工作描述了一系列季铵盐的合成以及它们的体外抗菌活性和细胞毒性的评估。还包括对化合物的结构-活性关系的初步讨论。制备了三个系列的季铵盐:(i)卤甲基化的季铵盐(系列I);(ii)非卤化季铵盐(II系列)和(iii)卤甲基化胆碱类似物(III系列)。使用MTT(3-(4 (5-5-二甲基噻唑-2-基)-2,5-二苯基-溴化四唑)微方法。还对L.的胞内变形虫测试了抗利什曼活性。(五)巴拿马流式细胞仪。大多数化合物对人U937细胞具有高毒性,其致命浓度50(LC50)值在9至46μg/ mL范围内。大多数化合物证明具有抗菌活性。在轴突性吻合动物中,抗菌活性从14到57μg/ mL不等,而在细胞内的吻合动物中,其活性从17到50μg/ mL不等。N-氯甲基-N,N-二甲基-N-(4,4-二苯基丁-3-烯-1-基)碘化铵(1a),N-碘甲基-N,N-二甲基-N-(4,4-二苯基丁-3-烯-1-基)
