Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The therapeutic use of cannabinoid compounds, particularly varins, is hindered by the difficulty in obtaining high yields due to challenges in extraction, isolation, and purification from the Cannabis plant, where cannabinoids are present in low quantities and are difficult to separate from terpenes and other plant components.
Innovation Solution
A biphasic solvent system is used, where a cannabinoid precursor is contacted with a cannabinoid synthase in a bioreactor, utilizing immiscible phases to facilitate the production of cannabinoids, with enzymes like CBDA synthase and THCA synthase catalyzing the conversion of substrates into desired compounds like THCVA, CBDVA, and CBCVA.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If extraction and isolation methods are used to obtain cannabinoids from Cannabis plant, then therapeutic compounds can be obtained, but yields are low and separation from terpenes and other plant components is difficult
Solution Approach 1:
The patent divides the synthesis process into two separate phases: Phase 1 performs cyclization of CBGA to CBDA using CBDA synthase, and Phase 2 performs conversion of CBDA to THCA using THCA synthase. This segmentation allows each enzyme to operate under optimized conditions and simplifies the overall process control, resolving the complexity of obtaining high yields through traditional extraction methods
Solution Approach 2:
The patent uses CBGA (cannabigerolic acid) as an intermediary substrate that can be converted to different cannabinoids through enzymatic action. By introducing this intermediate compound and using specific enzyme catalysts (CBDA synthase and THCA synthase), the process achieves high-yield conversion to desired cannabinoid products without the difficulties of plant extraction and purification
2Productivity
If chemical synthesis methods are used to produce cannabinoids, then production scale can be increased, but current chemical methods are not available for many cannabinoids and varins
Solution Approach 1:
The patent replaces traditional chemical synthesis mechanisms with enzymatic catalysis. Specific enzymes (CBDA synthase, THCA synthase) are used to catalyze the conversion of CBGA to CBDA and then to THCA, providing a biologically-based alternative to unavailable chemical synthesis methods for many cannabinoid compounds and varins
Solution Approach 2:
The patent changes the reaction parameters by using aqueous buffer systems (pH 4.5-7.5) and controlled temperature conditions (20-37°C) that optimize enzyme activity. These parameter changes enable high-yield production that is not achievable with traditional chemical synthesis methods, allowing large-scale production of cannabinoids and varins
