series of coumarin inhibitors of gyrase B bearing a N-propargyloxycarbamate at C-3' of noviose is presented. Replacement of the 5-methylpyrrole-2-carboxylate of coumarin drugs with an N-propargyloxycarbamate bioisostere leads to analogues with improved antibacterial activity. Analysis of crystal structures of coumarin antibiotics with the 24 kDa N-terminal domain of the gyrase B protein provides a
介绍了一系列在新出生的C-3'处带有N-炔丙氧基氨基甲酸酯的促旋酶B香豆素抑制剂的合成和体外生物学特性。用N-炔丙氧基氨基甲酸酯生物甾醇替代香豆素药物的5-甲基吡咯-2-羧酸酯可产生具有改善的抗菌活性的类似物。分析具有回旋酶B蛋白的24 kDa N末端结构域的香豆素抗生素的晶体结构,为C-3'N-烷氧基氨基甲酸酯的出色抑制能力提供了一个合理的理由。
