PF-514273 is a drug developed byPfizer, which acts as an extremely selectiveantagonist for theCB1receptor, with approximately 10,000x selectivity over the closely relatedCB2 receptor. This very high selectivity makes it useful for scientific research into these receptors, as many commonly usedcannabinoid receptor antagonists also block the CB2 receptor to some extent.[1]
