In plain terms

AS-1269574 is a laboratory molecule, developed in 2010 for diabetes research. It does not exist in hemp and has nothing in common with CBD: it acts on GPR119, a receptor neighbouring the endocannabinoid system that normally responds to fatty substances made by the intestine. In mice, it increases insulin secretion when blood sugar is high, and no trial has been conducted in humans.

Pharmacology

AS-1269574 is a synthetic agonist of GPR119, a Gs-coupled receptor activated by fatty acid amides and esters such as oleoylethanolamide and 2-oleoylglycerol, which attaches it to the periphery of the endocannabinoid system without making it a cannabinoid. At human GPR119 expressed in HEK293 cells, the measured potency is modest, with an EC50 of 2.5 µM, and a cryo-electron microscopy study published in 2026 describes it as a partial agonist: it occupies a restricted pocket of the activation cavity and stabilises a closed extracellular allosteric gate, which curbs the conformational change of the receptor and maintains low-efficacy signalling. The documented functional effects are an elevation of cyclic AMP, glucose-dependent insulin secretion in a pancreatic beta cell line, stimulation of proglucagon gene expression and GLP-1 release in entero-endocrine cells. A second mechanism complicates the reading: in 2016, the GLP-1 release obtained in the STC-1 line was attributed to direct activation of the TRPA1 channel, independently of cyclic AMP, an effect absent from the other GPR119 agonists compared. No activity at CB1 or CB2 has been measured, and anandamide itself does not activate GPR119. All the data remain preclinical and human data are lacking.

Origin (research tool)

No biological pathway: there is no biosynthesis for this molecule. It comes from synthetic chemistry, by amination of a halogenated 2-arylpyrimidine with ethanolamine, and belongs to the series of 4-amino-2-phenylpyrimidine GPR119 agonists.

Status
Unscheduled

4-aminopyrimidine substituée : noyau pyrimidine portant un groupe 4-bromophényle en position 2, un méthyle en position 6 et une chaîne aminoéthanol en position 4. Aucun squelette terpénophénolique de type cannabinoïde, aucune chaîne d'acide gras.

Pharmacokinetics

Aucun paramètre pharmacocinétique n'a été publié pour cette molécule. Son activité par voie orale chez la souris est documentée : une administration unique réduit l'excursion glycémique après charge orale en glucose sans modifier la glycémie à jeun (2010), et un traitement oral quotidien de 28 jours reste actif chez la souris diabétique (2016). Les données humaines manquent entièrement.

Metabolism

Aucune étude de métabolisme ni d'élimination n'a été publiée. Le seul élément disponible provient de la série chimique : une inhibition du cytochrome P450 1A2 (CI50 voisine de 0,66 µM) est enregistrée pour ce composé dans ChEMBL, d'après l'article de relation structure-activité de 2012. Cela signale un risque d'interaction métabolique, non un profil d'élimination.

Toxicology and risks

Le profil toxicologique n'est pas caractérisé et les données humaines manquent. Les travaux animaux publiés n'ont pas rapporté d'effet indésirable notable, mais ils portaient sur l'effet glycémique et non sur la toxicité, avec des effectifs réduits et sans examen histologique systématique. Deux éléments justifient la prudence : l'inhibition du CYP1A2 mesurée in vitro, et l'activation directe du canal TRPA1, canal sensoriel de l'irritation et de la douleur, décrite en 2016 et absente des autres agonistes de GPR119 testés dans la même étude.

Detection and analysis

Aucune méthode analytique dédiée n'est décrite dans la littérature médico-légale et la molécule n'apparaît dans aucun signalement de toxicologie ou de surveillance du marché des substances psychoactives.
