Tuberculosis is a serious public health problem worldwide. The search for new antibiotics has become a priority, especially with the emergence of resistant strains. A new family of imidazoquinoline derivatives, structurally analogous to triazolophthalazines, which had previously shown good antituberculosis activity, were designed to inhibit InhA, an essential enzyme for survival. Over twenty molecules were synthesized and the results showed modest inhibitory efficacy against the protein. Docking experiments were carried out to show how these molecules could interact with the protein's substrate binding site. Disappointingly, unlike triazolophthlazines, these imidazoquinoline derivatives showed an absence of inhibition on mycobacterial growth.
结核病是全球严重的公共卫生问题。寻找新的抗生素已成为当务之急,尤其是在耐药菌株出现的情况下。一组新型的咪唑并喹啉衍生物,其结构与三唑并酞嗪类似,先前已显示出良好的抗结核活性,被设计用来抑制 InhA,这是一种生存所必需的酶。合成了二十多个分子,结果表明这些分子对蛋白质具有适度的抑制作用。进行对接实验以表明这些分子如何与蛋白质的底物结合位点相互作用。令人失望的是,与三唑并酞嗪不同,这些咪唑并喹啉衍生物对分枝杆菌的生长没有抑制作用。
