HU-210 Kills Cancer Cells in Many Trials


"The synthetic cannabinoid HU-210 might cure some forms of cancer, kick start stem cells into regenerating nerve and other cells, and more, but there might be dangerous overtones...."  - MMJDOCTORONLINE


This article contains takeaway information about the most studied synthetic cannabinoid, HU-210. The information is applicable to both laymen and physicians alike and provide a comprehensive list of research studies that attest to the potential, efficacy and dangers of this very powerful cannabinoid.  Unfortunately, HU-210 is unavailable for prescription at this point, but many researchers believe that megadosing THC may achieve similar results.  


Nuclear Cannabinoids


So, what exactly is HU-210?

HU-210 is a psychoactive synthetic cannabinoid that acts somewhat like THC except it is much stronger. Though HU-210 is not normally found in Spice, a dangerous illegal mix of synthetic cannabinoid due to its poor smokability.  While Cannabinoids found in cannabis can be titrated at home, no one should mess about with HU-210 without a doctor's prescription and supervision.  A doctor's recommendation for medical marijuana does not entitle patients to buy or use HU-210, because it is not a marijuana component.  HU-210 is a pharmaceutical, plain and simple and is not allowed under prescription as a schedule I drug.

HU-210 first synthesized in 1988 at Hebrew University by a group led by Professor Raphael Mechoulam. Dr. Mechoulam was also Cannabis.  HU-210 was subsequently found to be 100 to 800 times more potent !!! than natural THC with an extended duration of activity. The "HU" stands for Hebrew University. 


"Evidence is emerging to suggest that cannabinoids are potent inhibitors of both cancer growth and spreading. Because cannabinoids are usually well tolerated and do not develop the toxic effects of conventional chemotherapeutics, more preclinical studies are warranted to investigate a potential utility of these substances as anticancer therapeutics."

Big Pharma Synthetic Cannabis Kills

Clinical and Scientific studies strongly suggest of find that HU-210

  • Increases blood supply and protects against hypothermia by binding to CB1 receptors, which influence cardiovascular function.
  • Protests against ischemic damage, the restriction in blood supply to tissues, resulting in a shortage of oxygen and glucose.
  • Neuroprotection results from the mirror image of HU-210 molecule, called HU-211 has very similar cannabinoid activity, except it acts as an antagonist (dials down receptor activity.
  • HU-210 promotes rapid cellular reproduction , but not differentiation, of cultured neural stem cells.
  • Increased neural growth led to antianxiety and antidepressant effects.
  • HU-210 is a potent pain killer similar to but more powerful than THC.

HU-210 molecule

  • HU - 210 Molecule - Slight differences in structure(compared to THC) amplify biochemical effects by 100 or more times.  
  • HU-210 was found to prevent inflammation found in Alzheimer's disease; stopped production of amyloid beta proteins.
  • HU-210 reduced cognitive impairment and loss of neuronal markers in Alzheimer's.
  • Cannabinoids including HU-210 completely negated neurotoxicity in rats.
  • HU-210 is a schedule I controlled substance under the CSA.   The drug or other substance has a high potential for abuse ;substance has no currently accepted medical use in treatment in the United States; there is a lack of accepted safety for use of the drug or other substance under medical supervision.


One little bond makes all the difference - HU-211


HU-211 - Nontoxic?  Brain Cancer Treatment?

The mirror image molecule of HU-210, Dexanabinol (HU-211) Unlike other cannabinoid derivatives, HU-211 does not act as a cannabinoid receptor agonist (activator) but instead has antagonist (dials down) effects and does not produce cannabis-like effects, However HU-211 demonstrates anticonvulsant and neuroprotective effects which imply efficacy in treating head injury, stroke, or cancer.   HU-211 was shown to be safe in clinical trials  and is currently studied in clinical trials for the treatment of brain cancer and advanced solid tumors.

Conclusion:  HU-210 study and application might best be focused on extremely difficult to treat and advanced and otherwise untreatable conditions; namely cancer, massive neurological damage and stem cell therapy.
