title: Structural modifications of the cannabinoid side chain towards C3-aryl and 1',1'-cycloalkyl-1'-cyano cannabinoids.
abstract: The compounds reported in this study are Delta(8)-THC analogues in which the C3 five-carbon linear side chain of Delta(8)-THC was replaced with aryl and 1',1'-cycloalkyl substituents. Of the compounds described here analogues 2d (CB(1), K(i)=11.7 nM. CB(2), K(i)=9.39 nM) and 2f (CB(1), K(i)=8.26 nM. CB(2), K(i)=3.86 nM) exhibited enhanced binding affinities for CB(1) and CB(2), exceeding that of Delta(8)-THC. Efficient procedures for the synthesis of these novel cannabinoid analogues are described.
