with activity against methicillin-resistant Staphylococcus aureus (MRSA) are described. The compounds were synthesized using substituted thiopyridones, generated either by cyclization of functionalized precursors, or by direct alkylation of the enolate of 2-methyl substituted pyrones. The most active compound in vitro against a strain of MRSA (A27223) displayed an MIC of 0.5 microg/mL. The most efficacious
描述了十六种具有抗甲氧西林金黄色葡萄球菌(MRSA)活性的新型头孢菌素衍生物。使用取代的硫代吡啶酮合成这些化合物,该取代的硫代吡啶酮是通过官能化的前体的环化或通过2-甲基取代的吡喃酮的烯酸酯的直接烷基化而生成的。体外针对MRSA菌株(A27223)最具活性的化合物的MIC为0.5微克/毫升。体内最有效的化合物的PD50为2.1 mg / kg。
