Activities of HMR 3787, a new 2-fluoroketolide, and its (des)-fluor derivative, RU 64399, were tested against 111 Haemophilus influenzae and 26 H. parainfluenzae strains and compared with those of telithromycin, erythromycin, azithromycin, and clarithromycin. HMR 3787 and RU 64399 MICs were comparable with those of azithromycin but were less affected by incubation in CO(2). Time-kill studies of 12 strains showed that HMR 3787, RU 64399, and telithromycin were bactericidal against all strains after 24 h at two times the MIC.
对新型2-氟酮内酯类药物HMR 3787及其(去)氟衍生物RU 64399针对111株流感嗜血杆菌和26株副流感嗜血杆菌进行了活性测试,并与泰利霉素、红霉素、阿奇霉素和克拉霉素进行了比较。HMR 3787和RU 64399的最低抑菌浓度(MIC)与阿奇霉素相当,但在二氧化碳环境中孵育时受影响较小。对12株菌株的时间杀菌研究表明,HMR 3787、RU 64399和泰利霉素在两倍MIC浓度下作用24小时后对所有菌株均有杀菌作用。
