CB2 cannabinoid receptor ligands are known to be therapeutically important for the treatment of numerous diseases. Recently, we have identified the heteroaryl-4-oxopyridine/7-oxopyrimidine derivatives as highly potent and selective CB2 receptor ligands, showing that the pharmakodynamics of the new compounds was controlled by the nature of the heterocycle core. In this paper we describe the synthesis and biological evaluation of 7-oxo-4-pentyl-4,7-dihydro-[1,2,4]triazolo[1,5-a]pyrimidine-6-carboxamide derivatives that led to the identification of novel CB2 receptor inverse agonists. Cyclic AMP experiments on CB2 receptors expressed in CHO cells revealed that introduction of structural modifications at position 2 of triazolopyrimidine template changes the functional activity from partial to inverse agonism. The molecular docking analysis of the novel structures is reported.
