Biosynthesis: The Science That May Unlock the Medical Potential of Cannabis
Attitudes are changing fast on cannabis, and investors are taking note.
With the birth of legal recreational markets in places like California and a growing appreciation for the medical applications of cannabinoids such as CBD, the floodgates are open for companies to pursue new and groundbreaking opportunities in the sector.
Unlike other fields where medical research has been mainstream for many decades, the work behind cannabis – an incredibly complex plant – is only getting started.
Today’s infographic comes from InMed Pharmaceuticals and it explains the medical potential behind the 90+ cannabinoids that we have yet to fully understand.
It also details a scientific process known as biosynthesis, which helped revolutionize the production of insulin for diabetics. A process such as this may be a key in unlocking the medical potential of understudied cannabinoids.
The medical benefits of cannabis are many, and scientific research is being conducted to explore the application of the plant in several disease categories, including multiple sclerosis, seizures, glaucoma, cancer, Alzheimer’s, and migraines.
However, this is just the tip of the iceberg. To understand the full potential of the cannabis plant, you need to know what cannabinoids are, and how they work.
The Human Endocannabinoid System
Like all mammals, the human body is loaded with natural cannabinoid receptors.
These receptors interact with cannabinoids, which occur naturally in the human body, but also in the cannabis plant.
|Type of Cannabinoid||Description|
|Endocannabinoids||Made in the human body|
|Plant cannabinoids||Found in the cannabis plant|
|Synthetic cannabinoids||Manufactured artificially to mimic natural cannabinoids|
|Biosynthesized cannabinoids||Biofermentation process using E. Coli-based system, which creates cannabinoids identical to those found in nature|
Some cannabinoids you may know include THC and CBD – and they have a wide variety of applications. They also make up the majority of cannabinoids (by volume) that can be easily extracted from the plant.
However, there are actually 90+ other cannabinoids that have potential medical benefits as well, and they make up less than 0.1% of total biomass. Because they are so difficult to isolate, they remain understudied in medicinal science.
A Problem of Volume
With only a tiny portion of the cannabis plant having medicinal value (the cannabinoids), a large degree of biomass must be harvested to extract even small amounts of medicine.
For example, 3 lbs (1.36 kg) of hig-CBD flowers may only yield 50 grams of pharmaceutical-grade compounds.
But this ratio is even more strenuous for the 90+ rare cannabinoids that make up less than 0.1% of the plant. With costs in the millions of dollars-per-gram range, it is extremely cost prohibitive to be researching these cannabinoids in any in-depth capacity.
Biosynthesis for Cannabinoids?
The process of biosynthesis could be a clue to maximizing the potential of these understudied cannabinoids.
In fact, this innovation has already helped democratize access to insulin, which originally was an extremely rare and expensive compound. To get just eight ounces of insulin, over 5,000 pig pancreases had to be harvested and processed. With biosynthesis, that is no longer the case.
Biosynthesis is a process that can occur by genetically modifying an organism to produce a pharmaceutically bioactive compounds that it normally would not make. Biosynthesis could thus be used to produce rare cannabinoids that are biologically identical to those produced by the cannabis plant itself.
Here’s how it works:
1) A biosynthetic cluster is inserted into a DNA vector.
2) DNA is inserted into E. Coli bacteria, where it provides instructions to produce cannabinoid compound(s)
3) The process is conducted at a large scale, resulting in materials that can be further processed into purified cannabinoids
The Potential of Biosynthesis
The world’s largest cannabis biotech company, GW Pharmaceuticals, has signed a contract with British Sugar to grow 18 hectares of cannabis for its CBD epilepsy drug, Epidiolex™.
Equivalent to approximately 23 football fields of greenhouse space, this represents a considerable amount of resources and investment needed to grow enough crops to treat 40,000 children with the disease.
If biosynthesis can produce similar quantities of cannabinoids from a much smaller space, it would be disruptive to the industry. Further, it may also make getting other understudied cannabinoids more economic – helping to possibly unleash the full medicinal potential of the cannabis plant.
