Guineesine (or guineensine) is a compound isolated from long pepper (Piper longum)[1] and black pepper (Piper nigrum).[2]

It was first isolated, studied and named from Piper guineense.[3][4]

Research

Guineensine inhibits the cellular reuptake of anandamide and 2-arachidonoylglycerol in a mouse model (EC50 = 290 nM).[5] [6] This causes an increase in the activity of the two neurotransmitters which are classified as endogenous cannabinoids.

Guineesine can dose-dependently produce cannabimimetic effects in a mouse model[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) inverse agonist rimonabant.[5]

Guineesine is also a monoamine oxidase inhibitor (MAOI) in vitro (IC50 = 139.2 μM).[7]
