Oligonucleotide for modulating an isoform C beta-1 protein-kinase in the form of a skin depigmentation agent
US Patent 8252753
Publication date: Aug. 28, 2012
Assignee: LVMH Recherche
The purpose of this invention is an oligonucleotide with between 7 and 25 nucleotides, preferably 20, that is capable of specifically hybridizing with genes or products of genes coding for protein kinase C beta-1 (PKC beta-1). This invention also relates to the use of these oligonucleotide sequences as a depigmenting or bleaching agent for the skin in a cosmetic composition or in a topical pharmaceutical composition. According to the inventors, this invention solves the problems encountered in prior work by modulating the activation of the enzyme by phosphorylation instead of directly inhibiting the enzyme after it has been activated to obtain the depigmenting effect. Furthermore, these oligonucleotides according to the invention are not cytotoxic.
