Surotomycin

Surotomycin has been used in trials studying the treatment of Diarrhea and Clostridium Difficile Infection. It is a benzenebutanoic acid derivative patented by Cubist Pharmaceuticals, Inc. as antibacterial agents for the treatment of Gram-positive infections. Surotomycin has a fourfold greater in vitro potency than vancomycin against C. Difficile and other Gram-positive bacteria with minimal impact on the Gram-negative organisms of the intestinal microbiota. Surotomycin, given orally, has been shown to be highly effective against both initial and relapsing hamster Clostridium difficile-associated diarrhea, with a potency similar to vancomycin. Surotomycin is non-inferior to vancomycin and offers a promising alternative for the treatment and prevention of C. diff infection.
