New (Z)- and (E)-1-alkyl-3-(2-hydroxyphenyl)-4-styryl-1H-pyrazoles and (Z)- and (E)-3(5)-(2alkyloxyphenyl)-4-styryl-1H-pyrazoles were prepared by alkylation of (Z)- and (E)-3(5)-(2hydroxyphenyl)-4-styryl-1H-pyrazoles with a long chain alkyl bromide in basic medium. The affinity of these alkylated pyrazoles to both human CB1 and CB2 type cannabinoid receptors was evaluated. The results showed that some
