First described
Décrite en 2007 dans le Journal of Medicinal Chemistry par Khanolkar, Lu, Ibrahim et leurs collègues du laboratoire d'Alexandros Makriyannis, sous le code interne AM-1714. Elle y figure comme chef de file de la famille des cannabilactones, aux côtés de son analogue 9-méthoxylé AM-1710.
Origin
An entirely synthetic molecule, absent from cannabis and from every living organism. It was prepared in a university laboratory as a pharmacological tool, in order to separate effects mediated by the CB2 receptor from those of the CB1 receptor. It circulates only as a research reagent and has never been formulated for human use.

In plain terms

AM-1714 is a laboratory molecule, developed by university chemists in the 2000s and entirely absent from hemp. It binds almost exclusively to the CB2 receptor, the one found mainly in immune cells, and only very weakly to the CB1 receptor that carries the psychoactive effects of THC. It has never been studied in human beings and is found in no consumer product.

Pharmacology

AM-1714 belongs to the cannabilactone class, tricyclic cannabinoids close to cannabinol in which the pyran ring is replaced by a lactone. The binding assays published in 2007 give a sub-nanomolar affinity for the CB2 receptor (Ki of 0.82 nM on mouse splenic membranes) against 400 nM for the CB1 receptor (rat brain synaptosomes), that is roughly 490-fold selectivity in favour of CB2; agonist activity is confirmed by inhibition of forskolin-stimulated cAMP and by [35S]GTPγS binding. In a rat model of paclitaxel-induced neuropathy, the anti-allodynic effect is abolished by the CB2 antagonist SR144528 but not by the CB1 antagonist SR141716, which establishes mediation by the CB2 receptor. This is the fundamental difference from the synthetic cannabinoids of the black market, which owe their hazard to full agonism at the CB1 receptor where THC is only a partial agonist: AM-1714 has only a weak affinity for CB1 and its intrinsic efficacy at that receptor has not been characterised. The literature stops there. No data exist on TRPV1, GPR55, PPARγ or 5-HT1A, no metabolism or toxicity study has been published, and human data are entirely lacking.

Origin (pharmaceutical research → illicit market)

No biological pathway: the molecule derives from no plant or animal precursor. It is obtained by total synthesis of the benzo[c]chromen-6-one skeleton, the route published in 2020 relying on a Suzuki cross-coupling followed by a one-pot demethylation-cyclisation.

Status
Unscheduled

Cannabilactone : squelette 6H-benzo[c]chromén-6-one (dibenzo[b,d]pyran-6-one) hydroxylé en positions 1 et 9, portant une chaîne latérale 1,1-diméthylheptyle en position 3. La charpente tricyclique est celle du cannabinol, la fonction lactone remplaçant le groupement gem-diméthyle du cycle pyranique des cannabinoïdes classiques.

Pharmacokinetics

Aucune donnée humaine. Chez le rat, une administration systémique modifie les seuils de retrait de la patte dès la première demi-heure, l'effet maximal étant relevé environ trente minutes après l'injection puis décroissant au cours de l'heure et demie suivante. Ni la biodisponibilité, ni la demi-vie, ni le passage de la barrière hémato-encéphalique n'ont été quantifiés.

Toxicology and risks

Le profil de toxicité n'est pas documenté : aucune étude de toxicité répétée, aucune donnée de génotoxicité ou de reproduction, aucun cas humain rapporté. Les seules observations disponibles sont comportementales, chez le rongeur, où aucun déficit moteur n'a été relevé au rotarod dans les conditions où l'effet antinociceptif était mesuré. Cette absence de signal chez l'animal ne renseigne en rien sur la sécurité chez l'être humain, et un composé non classé n'est pas pour autant un composé sûr.

Detection and analysis

Aucune méthode analytique dédiée n'a été publiée pour cette molécule, qui ne figure ni dans les listes de l'EUDA ni dans celles de l'ONUDC recensant les cannabinoïdes de synthèse saisis. Elle n'est donc pas recherchée par les criblages toxicologiques de routine : sa mise en évidence supposerait un étalon de référence et une analyse ciblée par spectrométrie de masse.
