Penicillin sulfones, which structurally incorporate both a 6-position alkylidene substituent and a 2'beta substituent, have been synthesized and evaluated as inhibitors of class C and class A serine beta-lactamases. Incorporation of the 2'beta-substituent generally improves inhibitory activity. Substituents that improve transport across the bacterial cell membrane have also been incorporated.
已经合成并在结构上结合了6-位亚烷基取代基和2'β取代基的青霉素砜,并被评估为C类和A类丝氨酸β-内酰胺酶的抑制剂。2'β-取代基的掺入通常改善抑制活性。还掺入了改善跨细菌细胞膜运输的取代基。
