NESS-0327

Summary

NESS-0327 is a pharmaceutical substance utilized in scientific investigations, recognized for its remarkable role as a highly potent and exceedingly selective antagonist of the cannabinoid receptor CB1. Its antagonistic potency greatly surpasses the more commonly employed ligand, rimonabant. With an astounding Ki at CB1 measuring a mere 350 femtomolar (0.00035 nanomolar), NESS-0327 exhibits an extraordinary preference for CB1 over CB2, showcasing a selectivity that exceeds 60,000-fold.
It’s worth noting that, independently, two other research groups have reported more modest nanomolar affinities for CB1 concerning this compound, with values of 125 and 18.4 nanomolar. Unlike rimonabant, NESS-0327 doesn’t function as an inverse agonist at higher concentrations. Instead, it is a strictly neutral antagonist, effectively obstructing the CB1 receptor without eliciting any intrinsic physiological responses.
