Spiramycin X4281 · Preparation of sterile spectinomycinSpiramycin is a broad spectrum macrolide antibiotic effective against gram negative and gram positive bacteria as well as some Toxoplasma parasites. Spiramycin is a mixture of spiramycin I, II, and III and has been used to study sepsis in mice. Macrolide antibiotics are composed of a macrocyclic lactone ring attached to one or more deoxy sugars. They inhibit bacterial protein synthesis by irreversibly binding the P site of the 50s ribosome, preventing
