HU-210 is a synthetic cannabinoid that was first synthesized in 1988 from (1R,5S)-Myrtenol^[3] by the group led by Professor Raphael Mechoulam at the Hebrew University.^[4][5][6] HU-210 is 100 to 800 times more potent than natural THC from cannabis and has an extended duration of action.^[7] HU-210 is the (–)-1,1-dimethylheptyl analog of 11-hydroxy- Δ⁸- tetrahydrocannabinol, in some references it is called 1,1-dimethylheptyl- 11-hydroxytetrahydrocannabinol. The abbreviation HU stands for Hebrew University.

The (+) enantiomer of HU-210 has almost all of the cannabinoid activity, with the (-) enantiomer HU-211 being inactive as a cannabinoid but instead acts as an NMDA antagonist having neuroprotective effects.^[8][9]

Per a 2005 article in the Journal of Clinical Investigation, HU-210 promotes proliferation, but not differentiation, of cultured embryonic hippocampal NS/PCs likely via a sequential activation of CB1 receptors, G(i/o) proteins, and ERK signaling. It was also indicated by this increased neural growth to entail antianxiety and antidepressant effects.^[10]

HU-210, alongside other synthetic cannabinoids like WIN 55,212-2 and JWH-133, is implicated in preventing the inflammation caused by Amyloid beta proteins involved in Alzheimer's Disease, in addition to preventing cognitive impairment and loss of neuronal markers. This anti-inflammatory action is induced through the activation of cannabinoid receptors which prevents microglial activation that elicits the inflammation. Additionally, cannabinoids completely abolish neurotoxicity related to microglia activation in rat models.^[11]

HU-210 is a potent analgesic with many of the same effects as natural THC.

Illicit use

According to the U.S. Customs and Border Protection, HU-210 was discovered in Spice Gold products seized at the US border in January 2009. Over 100 pounds of Spice products were seized based on this finding,^[12]. HU-210 was also detected in three Spice products in the UK, as reported in June 2009.^[13].

Legal status

United States

HU-210 is currently a schedule I controlled substance under the Controlled Substances Act. ^[1]
