Description and Uses
Spiramycin was found in the culture broth of Streptomyces ambofaciens by Rhone Poulenc in 1954 and its acetate was synthesized by Kyowa Hakko Kogyo Co. in 1965. This antibiotic consists of three closely related macrolide components, I, II, and III, whose ratio is 2 : 1 : 1. Spiramycin shows almost the same antimicrobial spectrum and activity as the other macrolides, but its acetate, acetylspiramycin, has much better pharmacokinetic properties and activity in vivo.
