Cannabis Compounds Show Promise in Treating Neuroblastoma Cancer

For centuries, Cannabis has been used to treat everything from pain and nausea to insomnia and inflammation. But today, researchers are diving deeper into the plant’s potential, exploring its ability to affect change in our approach to cancer treatments.  Promisingly, a new study¹ published in Pharmaceuticals has just revealed multiple new insights involving the flowers of Cannabis sativa L. that could pave the way for new therapies, particularly for neuroblastoma, a childhood nervous system cancer.

Details of the Study – New Cannabis Compounds Discovered in the Lab

In this study, scientists from Korea’s Wonkwang University managed to isolate eleven distinct compounds from cannabis flowers, including:

• Two never-before-seen compounds.  One of these is a brand-new cannabinoid named cannabielsoxa.
• Three chlorin-type compounds, usually found in green plants, were identified in cannabis for the first time.
• Six well-known cannabinoids, such as CBD, CBDA, and Δ8-THC.

After isolating these compounds, they were then tested against SK-N-SH neuroblastoma cells to gauge any response – a standard model for studying aggressive pediatric cancers.  Upon doing so, the researchers found that seven out of the eleven compounds effectively reduced the growth of neuroblastoma cells. Cannabinoids had the strongest effects, with the most promising ones being:

• CBDA (Cannabidiolic Acid)
• CBDA Methyl Ester
• CBD (Cannabidiol)
• Δ8-THC (Delta-8 Tetrahydrocannabinol)
• CBC (Cannabichromene)

It was noted that compounds containing double bonds in their chemical structure appeared to produce the most potent anticancer effects.  These cannabinoids performed better than the newly discovered chlorin-type compounds, although two also showed promise.

Testing Cancer Cell Death at Lower Concentrations

Notably, the researchers went one step further in an attempt to confirm that the anticancer effects were not simply due to high doses.  To that end, the compounds were also tested at various lower concentrations: 2.5, 5, and 10 micromolar.

Even at the 5 micromolar level, several compounds – especially CBD and its acidic forms – significantly reduced the growth of cancer cells.  This is particularly intriguing, as it suggests that further research could see the development of new cancer treatments with these compounds, which may be effective in small, manageable doses.

Molecular Docking Shows How Cannabinoids Work

So we know there are promising benefits, but how does it all work?  To better understand this, the researchers used a computer simulation technique called molecular docking.  This approach is used to predict how well a molecule fits into the structure of a protein, similar to how a key fits into a lock.

They found that compounds like CBDA, CBDA methyl ester, and CBD showed strong binding to a protein associated with neuroblastoma (PDB ID: 4KUM).  In fact, their interactions were comparable to those of temozolomide, a chemotherapy drug often used for brain cancers.

Are These Cannabis Compounds Safe for Humans?

In addition to looking at effectiveness, the researchers also examined how these compounds might behave in the human body by predicting their expected absorption, metabolism, and potential toxicity.  It was found that:

• The top-performing cannabinoids showed high gastrointestinal absorption, which may work well as oral medications.
• CBD was predicted to cross the blood-brain barrier, a valuable trait for treating cancers in the nervous system.
• None of the tested compounds were flagged for problems such as drug resistance or toxicity concerns.

Overall, these cannabinoids appeared to be good candidates for further development as potential medications.

What Other Studies Say About Cannabis and Cancer

Notably, this latest research only adds to a growing body of evidence pointing to the potential for cannabis to play an expanded in cancer care.  This means not just by treating symptoms, but potentially by targeting tumors themselves.

A recent large observational study found that cannabis use led to significant improvements in quality of life for over 3,000 cancer patients.  Many reported reduced pain, better sleep, and less anxiety, with minimal side effects.

While there are undoubtedly benefits to be had, though, it would be foolish to think cannabis use is entirely without risk.  Another study on colon cancer patients found that individuals with Cannabis Use Disorder had poorer survival outcomes.  This suggests that overuse or dependency can interfere with effective cancer treatment, especially when cannabis is not used under medical supervision.

For now, the most common usage of cannabis among those living with cancer is for appetite stimulation.  For those wondering why cannabis makes people hungry, there is an explanation.  Cannabis increases levels of ghrelin, the hormone responsible for stimulating appetite.  While not ideal in every case, this helps many who are struggling to eat due to chemotherapy, particularly when weight gain or metabolic health is a concern.

Final Thoughts: Could Cannabis Become a Cancer Treatment?

Overall, this research is just the latest to offer a compelling glimpse into cannabis’s future in cancer care.  The fact that researchers were able to uncover not just one, but multiple previously unknown compounds is a stark reminder of how much we still have to learn about this plant.  While CBD and THC tend to dominate the spotlight, this study shows that cannabis harbors a much wider toolbox of compounds with the potential to impact serious diseases like neuroblastoma.

Though these findings are based on lab tests and more research is needed before clinical applications, the implications are exciting.  Each newly discovered compound expands our understanding of how cannabis might be used—not just for symptom relief, but as a targeted treatment.
