Description

Application of phenethyl and styryl resorcinol glycoside compounds in melanin generation inhibitor
Technical Field
The invention relates to the technical field of biology, and in particular relates to a phenethyl and styryl resorcinol glycoside compound and application thereof in preparation of a melanin generation inhibitor.
Background
Most Asian women pay attention to the fair and beautiful skin of the Asian women, and in the development history of China, the modern whitening cosmetics are close to the development history of the modern whitening cosmetics, the Asian women go through a whitening stage depending on physical covering, wherein the Asian women are most commonly used with white powder and lead powder, but the Asian women can cause cyan marks on the skin after long-term use, so that the appearance is influenced; the skin is then transferred to the "bleaching stage" where the whitening is achieved by erosion, exfoliation of the stratum corneum, which if used for a long period of time, destroys the skin barrier and makes the skin sensitive. With the progress of science and technology, people continuously deepen the understanding of whitening, and the currently accepted melanin production pathway in the world is as follows: tyrosine → dopa acid → dopaquinone → dopachrome (or dihydroxyindole acid) → melanin oligomer → melanin, so we have entered the "synergistic whitening" stage of achieving the purpose of whitening by adding inhibitors such as melanin production, melanin transfer, tyrosinase, etc., and the ingredients that are excellent in this stage are: hydroquinone, kojic acid, Vc, and the like. However, these molecules are directed only to the downstream melanogenesis pathway, and the cells often have a large stimulation or side effect due to the stress pathological compensatory function.
The nature of the melanin biosynthetic pathway is formed by a series of enzymatic and non-enzymatic reactions, Tyrosinase (TYR) is a key enzyme in the process, and its abnormal over-expression also has a great influence on melanin production. The existing whitening substances mainly affect the activity of tyrosinase and have small influence on the expression quantity of the tyrosinase. The compound which can inhibit the activity of tyrosinase and the expression level of tyrosinase is searched, so that the inhibition effect on the generation of melanin can be greatly improved, and the whitening effect is improved. In addition, molecules with whitening activity, such as kojic acid, phenethyl resorcinol, etc., which are currently on the market, have the disadvantages of poor stability, large cytotoxicity and irritation. Although the stability of the lipid carrier can be improved by the lipid carrier technology, the irritation is not improved at all. Therefore, the finding of the compound which can inhibit the tyrosinase activity and remarkably inhibit the expression quantity of the tyrosinase, has good stability and small irritation and has important application significance.
Research shows that USF1 (upstream stimulating factor 1) is a key transcription regulator for tyrosinase synthesis, and our research finds that USF1 can promote tyrosinase expression by forming a transcription complex with regulatory interferon regulator 1(IRF1) under ultraviolet or inflammation induction. And proline 4 hydroxylase beta polypeptide (P4HB) can regulate ubiquitination of IRF1 so as to regulate tyrosinase expression. The activity of P4HB is enhanced, IRF1 ubiquitination is increased, so that the formation of IRF1/USF1 transcription complex is reduced, and the effect of inhibiting TYR transcription and expression is further exerted. The small molecules capable of enhancing the activity of P4HB are found to be capable of inhibiting the expression of TYR protein and well inhibiting the generation of melanin.
