αamylase

α-Amylase, a hydrolase enzyme, catalyzes the hydrolysis of internal α-1,4-glycosidic linkages in starch, producing glucose and maltose.

Amylase (Diastase) is any one of a group of enzymes which catalyses the breakdown of starch into maltose.

Pinocembrin 7-O-[3''-O-galloyl-4'',6''-hexahydroxydiphenoyl]-β-D-glucoside can moderately inhibit α-amylase activity, with an IC50 value of 0.03 µmol ml.

7,4'-Di-O-methylapigenin (4',7-DIMETHOXY-5-HYDROXYFLAVONE) can inhibit α-glucosidase and α-amylase enzymes and enhance 2-NBDG uptake in L6 cells, it has hypolipidemic effect on mouse pre-adipocyte (3T3L1) cell lines.

Isookanin shows strong diphenyl(2,4,6-trinitrophenyl)iminoazanium (DPPH) radical-scavenging activity with the IC50 value of 7.9 ± 0.53 μM. Isookanin is a potent inhibitor of α-amylase (IC50=0.447 mg/ml).

Irilone is a flavonoid with α-amylase inhibitory activity and highly selective inhibition of CYP3A4. In addition, Irilone enhances progesterone receptor (PR) signaling via estrogen receptor (ER) and glucocorticoid receptor (GR) when combined with progesterone.Irilone has potential anti-inflammatory activity and inhibits nitric oxide (NO) production by lipopolysaccharide (LPS)-induced RAW264.7 in mouse macrophages.
