摘要:
A series of novel 4 ''-position modified macrolide derivatives has been synthesized via a facile procedure. Their in vitro antibacterial activities against constitutively erythromycin-resistant strains were evaluated. Among the derivatives tested, compound 8a which has 11,12-carbamate and 4 ''-O-heteroarylcarbamoyl groups was found to have potent activity against most resistant bacteria. (c) 2008 Elsevier Ltd.
