Three series of new cannabinoids were prepared and their affinities for the CB, and CB, cannabinoid receptors were determined. These are the 1-methoxy-3-(1',1'-dimethylalkyl)-, 1-deoxy-11-hydroxy-3-(1',1'-dimethylalkyl)- and 11-hydroxy-1-methoxy-3-(1',1'-dimethylalkyl)-Delta(8)-tetrahydrocannabin ols. which contain alkyl chains from dimethylethyl to dimethylheptyl appended to C-3 of the cannabinoid. All of these compounds have greater affinity for the CB, receptor than for the CB, receptor. however only 1-methoxy-3-(1',1'-dimethylhexyl)-Delta(8)-THC (JWH-229, 6e) has effectively no affinity for the CB, receptor (K-i = 3134+/-110 nM) and high affinity for CB2 (K-i = 18 2 nM).
