The investigation of natural and synthetic cannabinoid ligands, including (
-)-Delta(9)-tetrahydrocannabinol, cannabinol, cannabidiol, HU-210, HU-211,
CT3, CP 55,940, WIN 55,212-2, SR 14,1716A, anandamide, 2-arachidonoylglycer
ol, and numerous novel analogs, has led to important findings that have con
tributed to a better understanding of the role of these compounds in physio
logical processes. Their potential use for medicinal purposes is also bette
r understood as a result.
