title: Chemical modification of tylosin. Thioether derivatives of tylosin and demycarosyltylosin.
abstract: Thioether derivatives of tylosin and demycarosyltylosin were synthesized by Michael-type addition of thiol to C-11 of the enone moiety on the aglycone. Some of tylosin derivatives were effective to macrolide resistant Staphylococcus aureus, and their in vivo activities were same or superior than that of tylosin.
