thiosemicarbazones, semicarbazones, dithiocarbazates and hydrazide/hydrazones compounds. The minimal inhibitory concentration (MIC) of these compounds against Mycobacterium tuberculosis was determined. Their in vitro cytotoxicity to J774 cells (IC50) was determined to establish a selectivity index (SI) (SI = IC50/MIC). The best compounds were the thiosemicarbazones (2, 3 and 4) and the hydrazide/hydrazones (14, 15
这项研究的目的是从以前合成的化合物中鉴定出一种候选药物,用于开发抗结核治疗药物,该化合物是基于硫代半咔唑,半咔唑,二硫代咔唑和酰肼/ hydr化合物。确定了这些化合物对结核分枝杆菌的最小抑制浓度(MIC)。确定它们对J774细胞的体外细胞毒性(IC 50)以建立选择性指数(SI)(SI = IC 50 / MIC)。最好化合物是缩氨基硫脲(2,3和4)和酰肼/腙(14,15,16和18)。结果与通常用于治疗结核病的“一线”或“二线”药物相当或更好,表明这些化合物可作为抗结核药物的候选药物。
