Quinolonyl-beta-lactam antimicrobial agents (QLAs) contain quinolones chemically linked to beta-lactams, although the impact of linkage is poorly understood. Genetically defined Escherichia coli strains were used to determine structure-activity characteristics of three quinolone-penem QLAs. Results suggest that the leaving group resulting from beta-lactam hydrolysis may not be free quinolone.
喹诺酮基-β-内酰胺抗菌剂(QLAs)含有化学连接到β-内酰胺的喹诺酮,尽管连接的影响尚不清楚。使用基因定义的大肠杆菌菌株来确定三种喹诺酮-青霉烯QLAs的构效特征。结果表明,β-内酰胺水解产生的离去基团可能不是游离喹诺酮。
