HU-210 is a synthetic cannabinoid that was first synthesized in 1988 by the group led by Professor Raphael Mechoulam at the Hebrew University. HU-210 is 100 to 800 times more potent than natural THC from cannabis and has an extended duration of action. HU-210 is the (-)-1,1-dimethylheptyl analog of 11-hydroxy-Δ-tetrahydrocannabinol, in some references it is called 1,1-dimethylheptyl-11-hydroxytetrahydrocannabinol. The abbreviation HU stands for Hebrew University.
Per a 2005 article in the Journal Of Clinical Investigation, HU-210 with daily high doses over a few weeks stimulates neural growth in rats' hippocampus region, the opposite effect of drugs like alcohol, nicotine, heroin, and cocaine. It was also indicated by this increased neural growth to entail antianxiety and antidepressant effects.
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 agonization of cannabinoid receptors which prevents microglial activation that elicits the inflammation. Additionally, cannabinoids completely abolish neurotoxicity related to microglia activation in rat models.
HU-210 is a potent analgesic with many of the same effects as natural THC.
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,. HU-210 was also detected in three Spice products in the UK, as reported in June 2009..
