- Formula:C21H23NO5
- Molecular Weight:369.41
IUPAC Name: 2,3,9,10-tetramethoxy-5,6-dihydroisoquinolino[3,2-a]isoquinolin-7-ium hydroxide
InChIKey: FQXRAAFEBRSBND-UHFFFAOYSA-M
SMILES: COC(C=C1C2=CC3=CC=C4OC)=C(C=C1CC[N+]2=CC3=C4OC)OC.[OH-]
Biological Activity: Palmatine hydroxide is an orally active and irreversible indoleamine 2,3-dioxygenase 1 (IDO-1) inhibitor with IC50s of 3 μM and 157μM against HEK 293-hIDO-1 and rhIDO-1, respectively. Palmatine hydroxide can also inhibit West Nile virus (WNV) NS2B-NS3 protease in an uncompetitive manner with an IC50 of 96 μM. Palmatine hydroxide shows anti-cancer, anti-oxidation, anti-inflammatory, neuroprotection, antibacterial, anti-viral activities[1][2][3][4][5].
