OBAA Chemical Properties,Uses,Production

Uses

OBAA is a phospholipase A2 and HSP90 inhibitor.

Biological Activity

A potent inhibitor of phospholipase A 2 (IC 50 = 70 nM). Reduces bronchospasm in guinea pigs in vivo .

in vivo

The immunologically induced bronchospasm in guinea pigs is significantly and dose-dependently inhibited by OBAA (2.5-7 mg/kg i.v.)^[3].

IC 50

PLA2: 70 nM (IC₅₀)
