OSAJIN Chemical Properties,Uses,Production

Uses

Osajin is an inhibitor of carbonic anhydrase I and II isoenzymes for therapeutic application such as the treatment of glaucoma.

Definition

ChEBI: Osajin is a member of isoflavanones.

in vivo

Osajin and pomiferin attenuates the myocardial dysfunction provoked by ischemia reperfusion. This is confirmed by an increase in both antioxidant enzyme values and total antioxidant activity. The cardioprotection provided by osajin and pomiferin treatment results from the suppression of oxidative stress and this correlates with improved ventricular function^[3].

target

P450 (e.g. CYP17) | Bcl-2/Bax | Caspase
