Occurrence of a novel cannabimimetic molecule 2-sciadonoylglycerol (2-eicosa-5',11',14'-trienoylglycerol) in the umbrella pine Sciadopitys verticillata seeds.

Abstract
The umbrella pine Sciadopitys verticillata seeds were found to contain a substantial amount (16.7 nmol/g) of sciadonic acid (all-cis-5,11,14-eicosatrienoic acid)-containing 2-monoacylglycerol, i.e., 2-sciadonoylglycerol (2-eicosa-5',11',14'-trienoylglycerol). Because the structure of 2-sciadonoylglycerol closely resembles that of 2-arachidonoylglycerol, the endogenous natural ligand for the cannabinoid receptor, we examined whether or not 2-sciadonoylglycerol exhibits cannabimimetic activity using NG108-15 neuroblastomaxglioma hybrid cells which express the cannabinoid CB1 receptor. We found that 2-sciadonoylglycerol induces rapid transient elevation of intracellular free Ca2+ concentration in NG108-15 cells through a cannabinoid CBI receptor-dependent mechanism similar to the case of 2-arachidonoylglycerol, yet the activity of 2-sciadonoylglycerol was apparently lower than that of 2-arachidonoylglycerol. The activity of 2-sciadonoylglycerol was detectable from 3-10 nM, reaching a maximum at around 10 microM. To our knowledge, this is the first report showing the occurrence of a cannabimimetic monoacylglycerol in higher plants.
