QMPSB, initially identified as an aryl sulfonamide-based synthetic cannabinoid, found its place in the realm of designer drugs.
In 2007, Nathalie Lambeng and her research team unearthed QMPSB, unveiling its role as a robust full agonist of the CB1 and CB2 receptors, boasting impressive Ki values of 3 nM and 4 nM, respectively. Following this discovery, many related derivatives emerged, primarily focusing on enhancing selectivity for the non-psychoactive CB2 receptor. This pursuit continued earlier endeavors involving sulfamoyl benzamide derivatives, culminating in a patent filing 2004.
Interestingly, the distinct quinoline-8-yl ester motif present in QMPSB’s structure paved the way for the discovery of other designer cannabinoids, including notable compounds like PB-22 and BB-22.
