    Roseoflavin is an antibacterial pigment isolated from Streptomyces davawensis as an anti-metabolite of riboflavin. Roseoflavin has been shown to be an important regulator of bacterial gene expression by binding to untranslated regions of RNA, so-called ribo-switching sites.

    Roseoflavin is soluble in ethanol, methanol, DMF and DMSO.
    Mechanism of ActionRoseoflavin is used as a substrate to mimic riboflavin in flavin biosynthesis, but leading to the formation of inactive flavin co-factors.
    Molecular FormulaC18H23N5O6
