Furo[2,3-b]pyridine-based cannabinoid-1 receptor inverse agonists: synthesis and biological evaluation. Part 1.

The synthesis, SAR and binding affinities of cannabinoid-1 receptor (CB1R) inverse agonists based on furo[2,3-b]pyridine scaffolds are described. Food intake, mechanism specific efficacy, pharmacokinetic, and metabolic evaluation of several of these compounds indicate that they are effective orally active modulators of CB1R.
