1,1-Dimethylheptyl-11-hydroxytetrahydrocannabinol

The Uses of 1,1-Dimethylheptyl-11-hydroxytetrahydrocannabinol

HU 211-d6 is labelled HU-211 (H673505) which is a novel TNF-α inhibitor and an effective neuroprotectant. It might be a useful agent for the treatment of stroke patients, by protecting neuronal lysosomes from nitric oxide (NO)-mediated toxicity.

Biological Activity

NMDA antagonist (IC 50 = 11 μ M for inhibition of [ 3 H]MK-801 binding to rat forebrain membranes). Protects against NMDA- and quisqualate-induced neurotoxicity (EC 50 = 3.8 μ M) and enhances dopamine D 1 receptor activity. Inhibits NF- κ B, reducing TNF- α , IL-6 and nitric oxide production, and acts as a free radical scavenger. Exhibits beneficial effects in experimental models of multiple sclerosis, bacterial meningitis, septic shock, epilepsy, and traumatic and ischemic brain injury. Brain penetrant.
