What is Ribocil?

Description

Ribocil is a synthetic mimic of riboflavin 5’-monophosphate (FMN; ) that competes with the natural ligand to inhibit FMN riboswitch-mediated expression of ribB, a gene responsible for the synthesis and transport of riboflavin. Ribocil depletes cellular levels of riboflavin with an IC₅₀ value of 0.3 μM and inhibits E. coli growth with an MIC value of 2 μg/ml.
