Summary
ADSB-FUB-187, an indazole-based synthetic cannabinoid, exhibits remarkable potency as a CB1 receptor agonist, boasting an impressively low binding affinity with a Ki value of 0.09 nM and an EC50 of 1.09 nM. Pfizer’s 2009 patent, WO 2009/106982, introduced this compound as example 187. While it stands out as the most tightly binding substance within this patent in terms of Ki, it’s essential to note that it doesn’t rank as the most potent compound in terms of producing a CB1-mediated pharmacological effect. At least 17 other compounds from the same patent exhibit lower EC50 values in this regard.
