Deazaflavin (TND-1128) is a synthetic flavin analog belonging to the 5-deazaflavin family, characterized by the replacement of the nitrogen atom at position 5 of the isoalloxazine ring with a carbon atom. This structural modification fundamentally alters the redox chemistry of the molecule.
Synonyms: Deazaflavin, 5-Deazaflavin, TND-1128, Pyrimido[4,5-b]quinoline-2,4(1H,3H)-dione, NSC 106042, Denitrifying flavin, Deazoflavin, 1H,2H,3H,4H-Pyrimido[4,5-b]quinoline-2,4-dione
Relationship to other deazaflavins:
| Compound | CAS No. | Position 5 | Key Difference |
|---|---|---|---|
| 5-Deazaflavin | 26908-38-3 | Carbon (C) | C at position 5, H at N3? |
| Deazaflavin (TND-1128) | 59997-14-7 | Carbon (C) | Different substitution pattern |
| Natural flavin (riboflavin) | 83-88-5 | Nitrogen (N) | Natural cofactor |
| F420 cofactor | Various | Carbon (C) | Natural deazaflavin (archaea/mycobacteria) |
Unlike natural flavins (riboflavin, FMN, FAD), deazaflavin analogs cannot form the N5-C4a adduct intermediate that is critical for many flavin-catalyzed reactions. This property makes deazaflavins valuable mechanistic probes for studying flavoprotein function.
