The bacterial deacetylase LpxC is a promising target for the development of antibiotics selectively combating Gram-negative bacteria. To improve the biological activity of the reported benzyloxyacetohydroxamic acid 9 ((S)-N-hydroxy-2-2-hydroxy-1-[4-(phenylethynyl)phenyl]ethoxy}acetamide), its hydroxy group was replaced by a triazole ring. Therefore, in divergent syntheses, triazole derivatives exhibiting
细菌脱乙酰基酶LpxC是开发选择性对抗革兰氏阴性细菌的抗生素的有希望的目标。为了提高已报道的苄氧基乙酰氧肟酸9((S)-N-羟基-2- 2-羟基-1- [4-(苯基乙炔基)苯基]乙氧基}乙酰胺)的生物活性,其羟基被三唑代替环。因此,在不同的合成中,三唑衍生物具有刚性和柔性的亲脂性侧链,在其立体中心具有不同的构型,并且在三唑环上具有各种取代方式,并测试了其抗菌和LpxC抑制活性,并基于此推导了结构-活性关系。对接和约束能的计算。
