4'''-N-demethylspiramycin derivatives: synthesis and evaluation of effectiveness against drug-resistant bacteria

J Antibiot (Tokyo). 2008 Mar;61(3):175-84. doi: 10.1038/ja.2008.127.

Abstract

18-amino-4''-O-benzoyl-4'''-N-demethyl-18-deoxospiramycins were designed and synthesized. Synthetic strategy involved selective demethylation of the dimethylamino group in forosamine, benzoylation of the hydroxyl group at the C4'' position and reductive N-amination of the formyl group. Antibacterial characteristics of spiramycin derivatives were tested. The derivatives exhibited promising activity against drug-resistant bacterial strains.
