A series of 2-oxaisocephems with a thio-substituted methyl group at the 3-position and a [2-(5-amino-1,2,4-thiadizol-3-yl)-2-(Z)-alkoxyimino]acetamido moiety at 7-position were synthesized and tested for their antibacterial activities. The analogs 17c and 17f have well-balanced potency and significantly enhanced activity as compared with the reference compound ceftazidime.
一系列 2-氧代异头孢烯类化合物,其 3-位具有硫取代甲基,7-位具有 [2-(5-氨基-1,2,4-噻二唑-3-基)-2-(Z)-烷氧基亚氨基]乙酰胺基部分,被合成并测试了它们的抗菌活性。与参比化合物头孢他啶相比,类似物 17c 和 17f 具有平衡的效力和显著增强的活性。
