Pharmacology

Tetrahydrocannabivarinic acid (THCVA) is the acid precursor of THCV, produced in cannabis from CBGVA by THCV synthase. In this acid form, it interacts only very weakly with the CB1 and CB2 receptors; it is its decarboxylation by heat or light that releases THCV, described in the literature as an antagonist at the CB1 receptor and a partial agonist at the CB2 receptor. It belongs to the varinic series, with a propyl chain.

Biosynthetic pathway

In the plant, divarinolic acid condenses with geranyl pyrophosphate to form cannabigerovarinic acid (CBGVA), the common precursor of the varinic series. THCV synthase then cyclises CBGVA into tetrahydrocannabivarinic acid (THCVA). Under the effect of heat or light, THCVA decarboxylates into THCV.

Structural classification

Class
Major phytocannabinoid
Origin

Status
Narcotic: generic clause

Cannabinoïde phytocannabinoïde de type THC (noyau tétrahydrobenzo[c]chromène, ou dibenzopyrane), sous sa forme acide carboxylique. Il appartient à la série varinique, caractérisée par une chaîne latérale propyle en C3 : deux carbones de moins que la chaîne pentyle des cannabinoïdes classiques.

Pharmacokinetics

Comme les autres cannabinoïdes acides, le THCVA est thermolabile : il se convertit en THCV lors du chauffage, ce qui conditionne fortement l'exposition réelle selon le mode de consommation.

Detection and analysis

En laboratoire, le THCVA se distingue du THCV par chromatographie (HPLC à froid) qui préserve la forme acide, alors que la chromatographie gazeuse, en chauffant l'échantillon, le décarboxyle en THCV.
