4 Presentation A GP4G is a cosmetic active ingredient extracted from the plankton artemia salina. GP4G is designed for energizing and regenerating skin care products. GP4G also offers a new way to increase cellular defenses against UV stress and shows multiple protective effects : Increases cellular protection against UV aggressions and DNA damage. Stimulates HSP70, proteins implicated in the fight against cellular stress, and increases skin defenses as well as resistance to UV- and heat-stress. Offers an anti-inflammatory action by decreasing the level of inflammatory cytokines such as IL-1a, IL-8 and TNFa. Cyst of Artemia salina with GP4G molecule 4

5 The GP4G Molecule A The originality of GP4G is based on its composition rich in nucleotide energetic messengers, and in particular, in the presence of an unusual nucleotide: Diguanosine tetraphosphate (GP 4 G) 5

6 Origin A 1. Artemia is a plankton that lives in hypermineral lakes since several millions of years. 2. When environmental conditions turn critical (stress), Artemia enters a state of dormancy, encapsulates and accumulates a vital molecule, the Diaguanosine Tetraphosphate (GP4G), a principal source of phosphate bonds with high energetic potential used for DNA protection as well as energy storage. 3. When environmental conditions turn favorable again, Artemia 'awakens', rehydrates and different metabolic activities take place again. Ultimately, GP 4 G is transformed into ATP. 4. GP4G provides Artemia with energy and protection for its survival and development.

10 Energy: GP4G is a stable precursor of ATP B µmoles/g protein 135 µg/ µµ/ GP4G ATP+ GP4G ATP 55 ATP Days GP4G When Artemia is awakened by favorable conditions, GP4G content declines rapidely while a sharp increase in ATP is observed. This is explained by a conversion of GP4G into ATP and a role of the GP4G in the awakening of the quiescent cells. 10

D A damage is evaluated by the size of the tail of the comet, in relation to the head (undamaged D A). GP4G Under low doses of UVB, when cells were treated with GP4G, very little damage was seen, in contrast to untreated cells. 18
