产品介绍
Lefamulin acetate是具有口服活性的抗生素。它是用于人体细菌感染的全身研究的半合成截短侧耳素。它与 50S 细菌核糖体的肽基转移酶peptidyl Transferase中心结合抑制蛋白质合成,并阻止了转移RNA与肽转移的结合。

产品描述

Lefamulin acetate (formally BC-3781 acetate) is a novel pleuromutilin antibiotic and is the first to be used for the systemic treatment of bacterial infections in humans. Lefamulin acetate (BC-3781 acetate) inhibits protein synthesis by binding to the peptidyl transferase center of the 50S bacterial ribosome, preventing the binding of transfer RNA for peptide transfer. Lefamulin acetate (BC-3781 acetate) is an orally active antibiotic for community-acquired bacterial pneumonia (CABP) treatment.
