Dexanabinol
Dexanabinol (HU-211 or ETS2101) is a synthetic cannabinoid derivative in development by e-Therapeutics plc. It is the "unnatural" enantiomer of the potent cannabinoid agonist HU-210. Unlike other cannabinoid derivatives, HU-211 does not act as a cannabinoid receptor agonist, but instead has NMDA antagonist effects. 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. It was shown to be safe in clinical trials and is currently undergoing Phase I trials for the treatment of brain cancer and advanced solid tumors.
