HU-210 is a synthetic cannabinoid that was first synthesized in 1988 from (1R,5S)-myrtenol[1] by a group led by Professor Raphael Mechoulam at the Hebrew University.[2][3][4] HU-210 is 100 to 800 times more potent than natural THC from cannabis and has an extended duration of action.[5] 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 acting as an NMDA antagonist having neuroprotective effects.[6][7]

HU-210 promotes proliferation, but not differentiation, of cultured embryonic hippocampal neural stem and progenitor cells likely via a sequential activation of CB1 receptors, Gi/o proteins, and ERK signaling. It was also indicated by this increased neural growth to entail antianxiety and antidepressant effects.[8]

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. In addition, cannabinoids completely abolish neurotoxicity related to microglia activation in rat models.[9]

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

Chemistry

HU-210 is the Enantiomer of HU-211 (Dexanabinol). The original synthesis of HU - 210 is based on an acid -catalyzed condensation of (–)-Myrtenol and 1,1-Dimethylheptylresorcinol (3,5-Dihydroxy-1-(1,1-dimethylheptyl)benzol).[10]

HU-210 synthesis

Recreational use

According to the U.S. Customs and Border Protection, HU-210 was discovered in Spice Gold incense products seized at the US border in January 2009. Over 100 pounds of Spice products were seized based on this finding.[11] HU-210 was also detected in three Spice products in the UK, as reported in June 2009.[12]

Legal status

United States

HU-210 is a schedule I controlled substance under the Controlled Substances Act.[13]

Banned in New Zealand as of 8 May 2014.[14]
