  Synthesis and biological activity of novel 1β-Methylcarbapenems with oxyiminopyrrolidinylamide moiety

  摘要：

  The synthesis and antibacterial activity of novel 1beta-methylcarbapenems 1a-f bearing oxyiminopyrrolidinylamide moiety at C-5 position of pyrrolidine are described. Most compounds exhibited comparable antibacterial activity to meropenem against a wide range of Gram-positive and Gram-negative organisms including Pseudomonas aeruginosa isolates. Of these carbapenems, 1a showed potent and broad spectrum of antibacterial activity and similar stability to DHP-I to meropenem. Against clinical isolates of 40 Gram-negative bacterial species including MDR and ESBL-producing strains, the selected carbapenem 1a possessed excellent in vitro activity except for MDR P. aeruginosa, and was comparable in potency to meropenem.

  H37Rv and drug-resistant clinical isolates. Among them, two compounds 7a and 7b exhibited excellent activity against the three tested strains. Both of them were comparable to the first-line anti-TB agents INH and RIF against MTB H37Rv, and were far more potent than INH and RIF against MDR-TB 16833 and 16995 strains. Thus, both of them could act as leads for further optimization.

  设计，合成了一系列肟官能化的硝基呋喃酰胺，并评估了它们对MTB H37Rv和耐药临床分离株的体外抗分枝杆菌活性。其中，两种化合物7a和7b对三种测试菌株表现出优异的活性。它们两者均与针对MTB H37Rv的一线抗结核病药物INH和RIF相当，并且比针对MDR-TB 16833和16995菌株的INH和RIF更有力。因此，它们两者都可以作为进一步优化的线索。
