Compounds inhibiting LpxC in the lipid A biosynthetic pathway are promising leads for novel antibiotics against multidrug-resistant Gram-negative pathogens. We report the syntheses and structural and biochemical characterizations of LpxC inhibitors based on a diphenyl-diacetylene (1,4-diphenyl-1,3-butadiyne) threonyl-hydroxamate scaffold. These studies provide a molecular interpretation for the differential
在脂质 A 生物合成途径中抑制 LpxC 的化合物是针对多重耐药革兰氏阴性病原体的新型抗生素的有希望的线索。我们报告了基于二苯基二乙炔(1,4-二苯基-1,3-丁二炔)苏氨酰异羟肟酸酯支架的 LpxC 抑制剂的合成和结构和生化特征。这些研究为具有取代的远端苯环的化合物的不同抗生素活性以及苏酮基的 C2 位置而非 C3 位置的绝对立体化学要求提供了分子解释。
