Plant Extracts Stabilizing FGF-2 Against Degradation

The patent employs plant-derived compounds (such as flavonoids, phenolic acids, and terpenoids) as intermediary substances that bind to FGF-2 and form protective complexes. These intermediary compounds shield the growth factor from thermal and enzymatic degradation at the skin level, thereby enhancing its stability and biological activity without requiring structural modification of FGF-2 itself.

The patent utilizes plant extracts containing multiple bioactive compounds that alter the chemical environment around FGF-2, changing parameters such as pH, oxidation-reduction potential, and molecular interactions. These parameter changes create a protective microenvironment that prevents degradation while maintaining FGF-2's biological function for skin regeneration.

The patent replaces complex, potentially problematic heparan sulfate proteoglycans with simpler, naturally occurring plant-derived compounds that are readily biodegradable and metabolized. These plant compounds (such as quercetin, catechins, and other polyphenols) provide temporary but effective protection during the critical period of FGF-2 action, then are safely eliminated without accumulating in the system.

The patent identifies and utilizes plant compounds that replicate or mimic the protective binding characteristics of heparan sulfate proteoglycans without requiring the complex proteoglycan structure. These simplified molecular copies achieve similar protective effects through analogous binding mechanisms, reducing complexity while maintaining functionality.

The patent employs plant-derived compounds that provide partial protection to FGF-2, allowing it to remain stable long enough to exert its beneficial effects on skin cell proliferation and collagen synthesis, but not so stable that it accumulates to problematic levels. The plant compounds create a balanced protection that extends duration of action to the optimal therapeutic window without excessive persistence.

The patent utilizes the body's natural metabolic pathways to regulate the duration of FGF-2 action. Plant-derived compounds facilitate this self-regulation by being metabolized and eliminated through normal physiological processes, allowing the body to control the duration of FGF-2 activity and prevent unwanted accumulation or prolonged effects.
