Guineesine (or guineensine) is an alkaloid isolated from long pepper (Piper longum)[1] and black pepper (Piper nigrum).[2]
Biological activities
Reuptake inhibition
Guineenine seems to potently inhibit the cellular reuptake of anandamide and 2-arachidonoylglycerol (EC50 = 290 nM).[3][4] This causes an increase in the activity of the two neurotransmitters which are classified as endogenous cannabinoids.
Cannabimimetic effects
Guineesine can dose-dependently produce cannabimimetic effects[5] which are indicated by potent catatonic, analgesic, hypo-locomotive and hypo-thermic effects. In addition, the analgesic and catatonic effects were reversed by the cannabinoid receptor type 1 (CB1) antagonist rimonabant.[4]
Enzyme activities
Guineesine also appears to possess significant monoamine oxidase inhibitory (MAOI) effects (IC50 = 139.2 μM).[6]
