Abstract

The synthesis and SAR of 3-alkyl-4-aryl-4,5-dihydropyrazole-1-carboxamides 1-23 and 1-alkyl-5-aryl-4,5-dihydropyrazole-3-carboxamides 24-27 as two novel cannabinoid CB(1) receptor agonist classes were described. The target compounds elicited high affinities to the CB(1) as well as the CB(2) receptor and were found to act as CB(1) receptor agonists. The key compound 19 elicited potent CB(1) agonistic and CB(2) inverse agonistic properties in vitro and showed in vivo activity in a rodent model for multiple sclerosis after oral administration.
