Provided herein is macrolide compound and its use of treatment chronic respiratory disease. Specifically, it provides the compounds of formula (I) or pharmaceutically acceptable salts, stereoisomers and application thereof. The compounds are useful for treating chronic respiratory disease.
Structural factors behind erm macrolide resistance were studied through synthesis of new macrolide derivates possessing truncated desosamine sugar moieties and subsequent determination of their antibacterial activity. Synthesized compounds with 2'-deoxy and 3'-desmethyl desosamine rings demonstrated decreased antibacterial activity on the native Staphylococcus aureus strain and were inactive against constitutively resistance S. aureus. The obtained results indicate that steric repulsion between the dimethylated A2058 and desosamine ring cannot be considered as a primary reason for erm-resistance. (C) 2012 Published by Elsevier Ltd.
