HU-243 (AM-4056) is a
synthetic cannabinoid drug that is a single
enantiomer of the hydrogenated derivative of the commonly used reference agonist
HU-210
HU-210 is a synthetic cannabinoid that was first synthesized in 1988 from (1R,5S)-myrtenol by a group led by Raphael Mechoulam at the Hebrew University. HU-210 is 100 to 800 times more potent than natural THC from cannabis and has an extended d ...

The above chemical name ("3-dimethylheptyl-11-hydroxyhexahydrocannabinol") and common ("canbisol") or trade names ("nabidrox") are not the same chemical as HU-243. They identify Canbisol, of which HU-243 is a methylene homologue.
