AB-CHFUPYCA is a compound that was first identified as a component of synthetic cannabis products in Japan in 2015.[1] The pharmacological properties of this compound have not been formally studied or reported in the scientific literature, but its discovery in recreational drug products suggests that it is intended be a cannabinoid agonist. Although AB-CHFUPYCA contains structural elements common to the synthetic cannabinoid designer drugs AB-PINACA and AB-FUBINACA, it can also be considered an analog of the traditional pyrazole cannabinoid receptor 1 antagonist rimonabant.
