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.

| Соединение | CAS No. | Position 5 | Key Difference |
|---|---|---|---|
| 5-деазафлавин | 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.
