Summary

5F-CUMYL-PINACA, also recognized as SGT-25 and occasionally marketed in e-cigarette form as C-Liquid, is a synthetic cannabinoid with an indazole-3-carboxamide base.
This compound acts as a potent agonist for cannabinoid receptors. According to the initial patent, it displayed approximately fourfold selectivity for CB1 receptors, boasting an EC50 of <0.1 nM for human CB1 receptors and 0.37 nM for human CB2 receptors. However, more recent assays using different techniques have yielded varying results. Some studies indicate an EC50 of 0.43 nM at CB1 and 11.3 nM at CB2, suggesting a roughly 26-fold CB1 selectivity. Alternatively, another data set suggests 15.1 nM at CB1 and 34.8 nM at CB2 with only 2.3 times selectivity. It’s worth noting that these figures cannot be directly compared due to the differing assay techniques used in each case.
