Pharmacology

Spectinomycin is an aminocyclitol antibiotic produced by a species of soil microorganism designated as Streptomyces spectabilis. In vitro studies have shown spectinomycin to be active against most strains of Neisseria gonorrhoeae (minimum inhibitory concentration <7.5 to 20 mcg/mL). Footprint studies indicate that spectinomycin exerts regional effects on ribosomal structure.

Toxicity
