Synthesis of novel 15-membered 8a-azahomoerythromycin A acylides: Consequences of structural modification at the C-3 and C-6 position on antibacterial activity
New series of acylides were designed and synthesized. Analogs were evaluated against a variety of susceptible and resistant pathogens. Acylide 15na showed an excellent, well balanced antibacterial activity. In vivo efficacy of compound 15na was superior to telithromycin (1). In addition 15na exhibited good oral bioavailability (average F = 42%).
