New Treatment to Prevent Skin Inflammation and atopic dermatisis
Thématique :


The invention refers to novel tocotrienol derivatives that specifically inhibit 5-lipoxygenase (5-LOX) activity and leukotrienes synthesis. Leukotrienes promote inflammation. Novel tocotrienol derivatives strongly inhibit 5-LOX activity at very low concentrations (nanomolar levels) thus preventing leukotrienes synthesis and inflammation.

A screening step has revealed many secondary metabolites isolated from Garcinia amplexicaulis and Garcinia kola as potential anti-inflammatory agents. In vitro tests highlighted 2 hits : garcinoïc acid and α-amplexichromanol. As a consequence, additional tests were realized on an atopic dermatitis Reconstructed Human Epidermis model (RHE) by SYNELVIA in Toulouse : α-amplexichromanol proved to prevent atopic dermatitis. Its anti-inflammatory activity is close to that of dexamethasone, a strong dermocorticoid with huge side-effects.

Reactive/sensitive skin and atopic dermatitis are major hurdles in the field of dermo-cosmetology and represent huge markets. Many companies are looking for innovative technologies and natural ingredients to prevent skin inflammation. Tocotrienol derivatives proved to be efficient molecules targeting inflammation. RHE in vitro tests confirmed their ability to prevent inflammation and atopic dermatitis. Moreover raw materials sourcing are clearly identified and processes are easy to scale-up.
