and some of them displayed an efficient antileishmanial activity. Among the compounds tested, the catecholic derivative 2‐[2‐(2‐methyl‐5‐nitro‐1H‐imidazol‐1‐yl)ethyl]sulfanyl}ethyl 3,4‐dihydroxybenzoate (9a, LC50 = 13 and 11 µM) and the pyrogallolic derivative 2‐[2‐(2‐methyl‐5‐nitro‐1H‐imidazol‐1‐yl)ethyl]sulfanyl}ethyl 3,4,5‐trihydroxybenzoate (9b, LC50 = 4 and 1 µM) were the most active ones against
通过将 2-[2-(2-甲基-5-硝基-1H-咪唑-1-基)乙硫基]乙醇与不同取代的苯甲酸偶联,合成了一系列新的含硝基咪唑的衍生物。用 m-CPBA 处理后,这些硫酰基化合物中有 12 种被进一步氧化成它们的磺酰基类似物。检查了所有 26 种合成化合物对巴西利什曼原虫 (V.) 和墨西哥利什曼原虫 (L.) 的体外活性,其中一些显示出有效的抗利什曼原虫活性。在测试的化合物中,儿茶酚衍生物 2-[2-(2-methyl-5-nitro-1H-imidazol-1-yl)ethyl]sulfanyl}ethyl 3,4-dihydroxybenzoate (9a, LC50 = 13 and 11 µM ) 和邻苯三酚衍生物 2-[2-(2-methyl-5-nitro-1H-imidazol-1-yl)ethyl]sulfanyl}3,4,5-trihydroxybenzoate (9b
