7,8-didemethyl-8-hydroxy-5-deazariboflavin

7,8-didemethyl-8-hydroxy-5-deazariboflavin, also known as Fo(α)-8-hydroxy-7,8-didemethyl-5-deazariboflavin, is a modified form of the vitamin riboflavin (vitamin B2). It is an organic compound with a chemical formula of C14H14N4O3. This compound is a derivative of the cofactor flavin mononucleotide (FMN), which plays a critical role in various biological processes, including energy production and metabolism. The modification of FMN to form 7,8-didemethyl-8-hydroxy-5-deazariboflavin alters its spectral properties and its ability to participate in electron transfer reactions. 7,8-didemethyl-8-hydroxy-5-deazariboflavin is found in some microorganisms, where it functions as a cofactor in certain enzymatic reactions. It has been studied for its potential as a fluorescent probe for biological imaging, due to its unique optical properties and ability to bind to certain proteins and enzymes. Overall, while 7,8-didemethyl-8-hydroxy-5-deazariboflavin is not well known, its modification of the important cofactor FMN highlights the potential for modifications of essential biological molecules to play important roles in various cellular processes.
