4-Hydroxycoumarin

Research use only, not for human use.

4-Hydroxycoumarin, a coumarin derivative.4-Hydroxycoumarin serves as an immediate precursor of 4-hydroxycoumarin (4HC) type anticoagulants (for example, warfarin).?4-Hydroxycoumarin derivatives ?are employed as the anticoagulant, antibacterial, antifungal, antiviral, antitumor, antiprotozoal, insecticidal, antimycobacterial, antimutagenic, antioxidant, anti-inflammatory agents, HIV protease inhibitors and tyrosine kinase inhibitors.

METHODS AND RESULTS:Six 3-aryl-4-Hydroxycoumarin derivatives were synthesized from 4-Hydroxycoumarin as precursor in order to evaluate changes in their antioxidant properties due to C3-aryl substituent nature. Free radical scavenging capacities of these compounds against two different species DPPH(·) and ABTS(·+) and the protecting ability towards the β-carotene-linoleic acid co-oxidation enzymatically induced by lipoxygenase were measured. In addition, the relationship between the activities of these molecules against DPPH radical and the bond dissociation energy of O-H (BDE) calculated using methods of computational chemistry was evaluated.
