Ribocil

Ribocil is a selective inhibitor targeting the bacterial FMN riboswitch, regulating the bacterial riboflavin riboswitch. Ribocil competitively binds to the FMN binding site, mimicking the natural ligand FMN to induce conformational changes in the riboswitch, inhibiting ribB gene expression, reducing riboflavin synthesis, and thus inhibiting bacterial growth. Ribocil strongly inhibits GFP expression (EC50=0.3 μM) . Ribocil exhibits in vivo antibacterial activity in a mouse model and can be used to study antibacterial drugs related to drug-resistant bacterial infections and bacterial riboflavin metabolic pathways[1][2].
