Dexanabinol (HU-211 or ETS2101[1]) is a synthetic cannabinoid derivative in development by e-Therapeutics plc. It is the "unnatural" enantiomer of the potent cannabinoid agonist HU-210.[2] Unlike other cannabinoid derivatives, HU-211 does not act as a cannabinoid receptor agonist, but instead as an NMDA antagonist.[3] It therefore does not produce cannabis-like effects, but is anticonvulsant and neuroprotective, and is widely used in scientific research as well as currently being studied for applications such as treating head injury, stroke, or cancer.[4][5][6] It was shown to be safe in clinical trials[7] and is currently undergoing Phase I trials for the treatment of brain cancer[8] and advanced solid tumors.[9]
Clinical trials
Dexanabinol has been studied in IV administration and oral dosing.[10] e-Therapeutics is evaluating the compound in clinical trials for brain and solid cancers.[11] Phase II studies are planned based on the results of the current trials.
A phase 1b study for hepatocellular carcinoma and pancreatic cancer was started in 2015.[12]
Legal status
HU-211 is not listed in the schedules set out by the United Nations' Single Convention on Narcotic Drugs from 1961 nor their Convention on Psychotropic Substances from 1971,[13] so the signatory countries to these international drug control treaties are not required by said treaties to control HU-211.
United States
HU-211 is not listed in the list of scheduled controlled substances in the USA.[14] It is therefore not scheduled at the federal level in the United States, but it is possible that HU-211 could legally be considered an analog of Delta-8-THC (one of the THC isomers which is in Schedule I under the designation of "Tetrahydrocannabinols"), and therefore sales or possession could potentially be prosecuted under the Federal Analogue Act.[15]
HU-211 is a Schedule I controlled substance in Alabama.[16]
HU-211 is a Schedule I controlled substance in the state of Florida making it illegal to buy, sell, or possess in Florida.[17]
Effective January 1, 2016, HU-211 is a regulated drug in Vermont designated as a "Hallucinogenic Drug."[18]
