Novel 8a-aza-8a-homoerythromycin—4″-(3-substituted-amino)propionates with broad spectrum antibacterial activity
摘要:
Fifteen-membered 8a-aza-8a-homoerythromycins derived from either erythromycin or clarithromycin have been acylated to form 4 ''-O-propenoyl derivative. These functionalized analogues underwent Michael reaction with primary or secondary amines to afford novel 8a-aza-8a-homoerythromycin-4 ''-(3-substituted-amino)propionates. This preparative sequence was adapted so that analogues could be made by parallel synthesis. Among them, 4-quinolone derivatives show particularly good antibacterial potency against macrolide resistant bacteria, comparable or better than azithromycin and telithromycin. (C) 2010 Elsevier Ltd.

[EN] Disclosed are compounds having polybasic functionalities. The compounds inhibit bacterial efflux pump inhibitors and are used in combination with an anti-bacterial agent to treat or prevent bacterial infections. These combinations can be effective against bacterial infections that have developed resistance to anti-bacterial agents through an efflux pump mechanism. [FR] L'invention concerne des composés présentant des fonctionnalités polybasiques. Ces composés sont des inhibiteurs de pompes à efflux bactériennes et sont utilisés en combinaison avec un agent antibactérien pour traiter ou prévenir des infections bactériennes. Ces combinaisons peuvent être efficaces contre les infections bactériennes ayant développé une résistance contre des agents antibactériens par mise en oeuvre d'un mécanisme de pompe à efflux.
