AbstractThe structural diversity of synthetic cannabinoid receptor agonist (SCRA) new psychoactive substances (NPS) has increased since the first examples were reported a decade ago. 5F-PY-PICA and 5F-PY-PINACA were identified in 2015 as putative SCRA NPS, although nothing is known of their pharmacology. 5F-PY-PICA, 5F-PY-PINACA, and analogues intended to explore structure-activity relationships within this class of SCRAs were synthesized and characterized by nuclear magnetic resonance spectroscopy and liquid chromatography–quadrupole time-of-flight–mass spectrometry. Using competitive binding experiments and fluorescence-based plate reader membrane potential assays, the affinities and activities of all analogues at cannabinoid type 1 and type 2 receptors (CB1 and CB2) were evaluated. All ligands showed minimal affinity for CB1 (pKi < 5), although several demonstrated moderate CB2 binding (pKi = 5.45–6.99). At 10 μM none of the compounds produced an effect > 50% of CP55,950 at CB1, while several compounds showed a slightly higher relative efficacy at CB2. Unlike other SCRA NPS, 5F-PYPICA and 5F-PY-PINACA did not produce cannabimimetic effects in mice at doses up to 10 mg/kg.

Original Reference

An index of fatal toxicity for new psychoactive substances has been developed based solely on information provided on death certificates. An updated index of fatal toxicity (Tf), as first described in 2010, was calculated based on the ratio of deaths to prevalence and seizures for the original five substances (amphetamine, cannabis, cocaine/crack, heroin and 3,4-methylenedioxymethylamphetamine)*. These correlated well with the 2010 index. Deaths were then examined for cases both where the substance was and was not found in association with other substances. This ratio (sole to all mentions; S/A) was then calculated for deaths in the period 1993 to 2016. This new measure of fatal toxicity, expressed by S/A, was well-correlated with the index Ln (Tf) of the original reference compounds. The calculation of S/A was then extended to a group of new psychoactive substances where insufficient prevalence or seizure data were available to directly determine a value of Tf by interpolation of a graph of Tf versus S/A. Benzodiazepine analogues had particularly low values of S/A and hence Tf. By contrast, γ-hydroxybutyrate/γ-butyrolactone, α-methyltryptamine, synthetic cannabinoid receptor agonists and benzofurans had a higher fatal toxicity.
