Semisynthetic Macrolide Antibacterials Derived from Tylosin. Synthesis and Structure-Activity Relationships of Novel Desmycosin Analogues

A series of 20-O-substituted and 3,20-di-O-substituted derivatives of desmycosin were synthesized and their biological properties were evaluated. In particular, we have synthesized numerous side chain modified analogues of desmycosin as well as some analo
