Cannabinoid ester constituents from high-potency Cannabis sativa

Area of Science:

• Phytochemistry
• Natural Products Chemistry
• Pharmacology

Background:

• Cannabis sativa is a source of diverse cannabinoids with potential therapeutic applications.
• Understanding the chemical composition of high-potency Cannabis varieties is crucial for exploring novel compounds.
• Cannabinoid esters and acids represent a less explored class of cannabis-derived molecules.

Purpose of the Study:

• To isolate and characterize novel cannabinoid esters and known cannabinoid acids from a high-potency Cannabis sativa variety.
• To evaluate the antimicrobial activity of the isolated compounds.
• To assess the binding affinity of isolated compounds to the CB-1 receptor.

Main Methods:

• Isolation of cannabinoids using chromatographic techniques.
• Structure elucidation through extensive spectroscopic analyses (NMR, MS, etc.).
• Antimicrobial activity testing against Candida albicans.
• CB-1 receptor binding assays.

Main Results:

• Eleven new cannabinoid esters and three known cannabinoid acids, including Delta9-tetrahydrocannabinol (Delta9-THC), were successfully isolated.
• Compound 8 (4-terpenyl cannabinolate) exhibited moderate antimicrobial activity against Candida albicans (IC50 = 8.5 microg/mL).
• The isolated cannabinoid acids and ester-containing fractions displayed low affinity for the CB-1 receptor.

Conclusions:

• The study expands the known repertoire of cannabis-derived cannabinoids, particularly cannabinoid esters.
• The findings suggest potential antimicrobial applications for specific cannabinoid derivatives.
• The low CB-1 receptor affinity of these compounds indicates distinct pharmacological profiles compared to classical cannabinoids.
