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 CB1 receptor agonist classes were described. The target compounds elicited highaffinities to the CB1 as well as the CB2receptor and were found to act as CB1 receptor agonists. The key compound 19 elicited potent CB1 agonistic and CB2 inverse
