Unraveling STS-135: A Synthetic Cannabinoid

Chemistry of STS-135

STS-135, scientifically termed N-(adamantan-1-yl)-1-(5-fluoropentyl)-1H-indole-3-carboxamide, belongs to the class of synthetic cannabinoids. Its chemical structure comprises a substituted indole group. Specifically, the indole moiety is substituted at R1 with a fluoropentyl chain, a feature shared with compounds like 5F-PB-22, THJ-2201, and 5F-AKB48. Furthermore, the indole is substituted at R3 with a carboxamide group, with the terminal amine group of this carboxamide being N-substituted with an adamantane group—a unique structural motif composed of four fused cyclohexane rings, forming what is termed a diamondoid. STS-135 can be considered an analog of 5F-AKB48, where the core indazole structure is substituted with an indole base.

Pharmacological Insights

Although formal studies regarding STS-135 are limited, structural analysis suggests similarities in its binding profile to that of other cannabinoids, including Δ9-THC. In vitro studies have indicated that STS-135 acts as a potent agonist for cannabinoid receptors, exhibiting an EC50 of 51 nM for human CB2 receptors and 13 nM for human CB1 receptors. Experimental evidence in rats has shown that STS-135 induces bradycardia and hypothermia at doses ranging from 1 to 10 mg/kg, further suggesting cannabinoid-like activity. However, the precise mechanisms underlying these interactions and their role in producing the subjective experience associated with cannabinoids remain poorly understood.
