N.; Whipple, David A.; Widlicka, Daniel W.; Wishka, Donn G.; Wolkowski, Joanna P.; Flanagan, Mark E. published the article 《Discovery of Azetidinyl Ketolides for the Treatment of Susceptible and Multidrug Resistant Community-Acquired Respiratory Tract Infections》 about this compound( cas:1569-17-1 ) in Journal of Medicinal Chemistry. Keywords: antibacterial azetidinyl ketolide preparation structure activity respiratory tract infection; crystal structure antibacterial azetidinyl ketolide preparation structure activity. Let’s learn more about this compound (cas:1569-17-1).
Respiratory tract bacterial strains are becoming increasingly resistant to currently marketed macrolide antibiotics. The current alternative telithromycin (1) from the newer ketolide class of macrolides addresses resistance but is hampered by serious safety concerns, hepatotoxicity in particular. We have discovered a novel series of azetidinyl ketolides that focus on mitigation of hepatotoxicity by minimizing hepatic turnover and time-dependent inactivation of CYP3A isoforms in the liver without compromising the potency and efficacy of 1.
