oroxin a

Oroxin A (Baicalin-7-glucoside) is a partial PPARγ agonist that can activate PPARγ transcriptional activation in vitro and in vivo. Oroxin A also exhibited inhibitory activity against α-glucosidase and antioxidant capacity.

Oroxin A (Baicalein 7-O-glucoside) has antitussive and expectorant effects.

Oroxin B (Hypocretin-2) has antioxidant activity.

Oroxylin A-7-O-glucuronide (Oroxylin A Glucoronide) and wogonoside should also be served as the chemical markers together with baicalin for the quality control of herbs and proprietary traditional Chinese medicine (PTCM) products of radix Scutellariae. Oroxylin A 7-O-glucuronide, Oroxin A, and Oroxin B can bind to the stem region of α-hemolysin (α-HL), when inhibiting the hemolytic activity of α-HL. Oroxylin A 7-O-glucuronide and 4', 5, 7-trihydroxy-6-methoxyflavone at a concentration of 100 microM inhibit 34 and 43% of total prolyl oligopeptidase (POP) activity, respectively.
