COSMETIC COMPOSITION COMPRISING AN ANTAGONIST OF THE NEUROPEPTIDE Y RECEPTOR

摘要

The bacterial strain Bacillus licheniformis SEBR 2464 (A) (deposited at the Pasteur Institute under the number CNCM 1778) and its productive mutants are new. Independent claims are included for: (i) the preparation of an alpha 2-antagonist product (I), by culturing (A) (or its mutant) in a fermentation medium under conventional conditions until the broth has alpha 2-antagonist activity, then extracting the supernatant and concentrating to give a solid extract; (ii) (I) obtained as in (i), where the dry extract is utilized after dilution with a cosmetically acceptable solvent; and (iii) a cosmetic composition containing (I) obtained as above, together with a cosmetic excipient.
