5 Deazaflavin CAS 26908-38-3

Redox Reactions:
5-Deazaflavin can act as a coenzyme in some flavoproteins, particularly in reactions involving two-electron transfers.
Antitumor Activity:
Certain 5-deazaflavin derivatives have shown promising antitumor activity, including inducing apoptosis and cell cycle arrest.
Radiosensitization:
Some 5-deazaflavin derivatives with sulfonamide moieties have been shown to act as radiosensitizers, increasing the effectiveness of radiation therapy.
PTK Inhibition:
5-Deazaflavins have been identified as potential inhibitors of protein tyrosine kinases (PTKs), which are important drug targets.
Antimicrobial and Anti-inflammatory Activity:
5-Deazaflavin derivatives have also shown potential as antimicrobial and anti-inflammatory agents.
Neurodegenerative Diseases:
A 5-deazaflavin derivative, TND1128, has been investigated for its potential to support energy production in the brain, even in cases of reduced blood flow, which could be relevant for conditions like Alzheimer's disease.
Key Differences from Flavins:
One-electron vs. Two-electron Transfer:
5-Deazaflavin is generally considered a two-electron acceptor/donor, while flavins can participate in both one- and two-electron transfers.
Stability of Radicals:
The 5-deazaflavin radical is generally less stable than the flavin semiquinone radical, leading to faster re-oxidation or disproportionation.
In summary, 5-deazaflavin is a valuable tool for studying flavin-dependent enzymes and has shown potential in various therapeutic applications due to its unique redox properties and structural similarity to flavins.
