Fatty acid amide hydrolase inhibitors. Surprising selectivity of chiral azetidine ureas.

We report the discovery of a novel, chiral azetidine urea inhibitor of Fatty Acid Amide Hydrolase (FAAH,) and describe the surprising species selectivity of VER-156084 versus rat and human FAAH and also hCB1.

Antagonists of the human A 2A receptor. Part 5: Highly bio-available pyrimidine-4-carboxamides

A novel series of antagonists of the human A(2A) receptor have been identified and have been shown to display good potency and high degrees of selectivity over other receptor sub-types. Displaying in vivo potency in commonly used disease models and high oral bio-availability, this class of compounds may serve as clinically useful treatments for the relief of the symptoms associated with Parkinsons disease.

Fatty acid amide hydrolase inhibitors. 3: Tetra-substituted azetidine ureas with in vivo activity

We describe here our attempts to optimise the human fatty acid amide hydrolase (FAAH) inhibition and physicochemical properties of our previously reported tetrasubstituted azetidine urea FAAH inhibitor, VER-156084. We describe the SAR of a series of analogues and conclude with the demonstration of in vivo dose-dependant FAAH inhibition in an anandamide-loading study in rats.
