Bicyclomycin, discovered in 1972, has a structure that is unique among antibiotics. Currently used to treat nonspecific diarrhea, it has a low toxicity, and no cross-resistance with other antibiotics has yet been found. It is effective against many Gram-negative bacteria. Bicyclomycin is also effective against the Gram-positive bacterium Micrococcus luteus.[1] It is the only known selective inhibitor of Rho.


Mode of Action

Bicyclomycin inhibits Rho by being a reversible, noncompetitive inhibitor of ATP.[1]
