The formation efficiency of hydride-induced Meisenheimer complexes of nitroaromatic compounds is consistent with their anti-TB activities exemplied by MDL860 and benzothiazol N-oxide (BTO) analogs. Herein we report that nitro cyano phenoxybenzenes (MDL860 and analogs) reacted slowly and incompletely which reflected their moderate anti-TB activity, in contrast to the instantaneous reaction of BTO derivatives
氢化物诱导的硝基芳香族化合物迈森海默复合物的形成效率与其以 MDL860 和苯并噻唑N-氧化物 (BTO) 类似物为例的抗结核活性一致。在此,我们报道硝基氰基苯氧基苯(MDL860和类似物)反应缓慢且不完全,这反映了它们中等的抗结核活性,而BTO衍生物的瞬时反应定量生成迈森海默复合物,这对应于它们增强的抗结核活性。这些结果得到了分枝杆菌和放射性标记研究的证实,这些研究证实了 BTO 衍生物而非 MDL860 类似物对 DprE1 酶的抑制作用。
