Abstract:
Syntheses of 7-hydroxy-10-methyl-5-deazaisoalloxazine (7-HMDI) and 8-hydroxy-10-methyl-5-deazaisoalloxazine (8-HMDI) are described. The physicochemical and biological properties of 8-HMDI, in contrast to those of 7-HMDI, are very analogous to those of F420, a coenzyme found in methanogenic bacteria.
