A Novel Glucosamine-Based Cannabidiol Complex Based on Intermolecular Bonding with Improved Water Solubility

Area of Science:

• Pharmacology
• Biochemistry
• Materials Science

Background:

• Cannabidiol (CBD) is a non-psychoactive compound with therapeutic potential, but its poor water solubility limits its bioavailability.
• Developing water-soluble formulations is crucial for improving the delivery and efficacy of CBD in biological systems.

Purpose of the Study:

• To synthesize and characterize a novel, patented water-soluble cannabidiol (CBD) complex.
• To evaluate the physicochemical properties and membrane permeability of the new CBD complex compared to conventional CBD.

Main Methods:

• Complex synthesis involving cannabidiol and glucosamine.
• Characterization using chromatography, thermal analysis, NMR, and FTIR spectroscopy.
• In vitro permeability tests across lipophilic membranes.

Main Results:

• The CBD-glucosamine complex exhibited significantly enhanced water solubility compared to conventional CBD.
• Permeability studies showed a five-fold decrease in membrane permeability and reduced membrane mass retention for the complex.
• The complex demonstrated a nearly four-fold higher equilibrium concentration, indicating improved bioavailability.

Conclusions:

• The novel water-soluble CBD complex offers improved physicochemical properties and enhanced bioavailability.
• This patented formulation presents a promising candidate for future biological and clinical investigations of CBD.
• The glucosamine-based complex represents a significant advancement in CBD drug delivery systems.
