Avenanthramide B
Avenanthramide B is an oat phytoalexin, a porcine liver esterase inhibitor, and an amyloglucosidase inhibitor, with an IC50 of 4.4 mg/mL against Aspergillus niger amyloglucosidase. Avenanthramide B increases the activation status of Akt1 and the expression level of eNOS, elevates the levels of NO and cGMP, and reduces the level of superoxide anions. Avenanthramide B acts on amyloglucosidase via a competitive mixed mechanism, functions as a fluorescence quencher, and exerts bidirectional regulatory effects on protein thermal stability. Avenanthramide B serves as a substrate for oat leaf peroxidase. Avenanthramide B can be used in research related to type 2 diabetes.

Akt1 |
Avenanthramide B (1 µM; 24 h) significantly increases intracellular NO levels and cGMP production, reduces superoxide anion generation, enhances Akt1 activation, and upregulates the protein expression level of eNOS in HUVEC cells[2].
Avenanthramide B (50 µM; 10 min) significantly inhibits the activity of porcine liver esterase[1].
Avenanthramide B (31.3-1000 μg/mL) inhibits amyloglucosidase derived from Aspergillus niger via a competitive-dominant mixed-type mechanism, with an IC50 value of 4.4 mg/mL[3].
