5F-CUMYL-PINACA also recognized as SGT-25 and occasionally marketed in e-cigarette form as C-Liquid, belongs to the category of indazole-3-carboxamide-based synthetic cannabinoids. It exerts its action as a potent agonist on cannabinoid receptors, with the original patent asserting approximately fourfold selectivity for CB1. It exhibits an EC50 of less than 0.1 nM for human CB1 receptors and 0.37 nM for human CB2 receptors.
In more recent assessments employing diverse techniques, 5F-CUMYL-PINACA displayed varying EC50 values, such as 0.43 nM at CB1 and 11.3 nM at CB2, indicating a somewhat elevated CB1 selectivity of 26 times. Alternatively, it was measured at 15.1 nM at CB1 and 34.8 nM at CB2 with only 2.3 times selectivity. However, it’s important to note that these figures cannot be directly compared due to the distinct assay techniques utilized in each case.
