JWH-133 is a potent selective CB2 receptor agonist with a Ki of 3.4nM and selectivity of around 200x for CB2 over CB1 receptors. It was discovered by and named after, John W. Huffman.

JWH-133, alongside WIN 55,212-2 and HU-210, is responsible for preventing the inflammation caused by Amyloid beta proteins involved in Alzheimer's disease, in addition to preventing cognitive impairment and loss of neuronal markers .[citation needed] This anti-inflammatory action is induced through agonist action at the CB2 receptor, which prevents microglial activation that elicits the inflammation. Additionally, cannabinoids at this receptor completely abolish neurotoxicity related to microglia activation in rat models.[citation needed]

It may be linked with anti-cancer properties, according to pre-trial data from a 2010 study in Madrid.[1]

Legal Status[edit]

As the U.S. Drug Enforcement Administration criminalizes any extract "containing one or more cannabinoids," JWH-133 is a scheduled substance in the U.S.[2] This is despite the low potential for abuse relative to its sister compounds such as JWH-018, as JWH-133 is selective for the non-psychoactive CB2 receptor and thus lacks significant psychoactive effects.
