Alpha-Arbutin

Ibisobanuro bigufi:

Alpha-Arbutin (4- Hydroxyphenyl- ± -D-glucopyranoside) ni ikintu cyiza, gishonga amazi, ibinyabuzima bikora neza.Alpha-Arbutin ihagarika epidermal melanin synthesis ihagarika okiside ya enzymatique ya Tyrosine na Dopa.Arbutin isa nkaho ifite ingaruka nke ugereranije na hydroquinone yibitekerezo bisa - birashoboka ko irekurwa buhoro buhoro.Nuburyo bwiza cyane, bwihuse kandi butekanye mugutezimbere-kumurika uruhu ndetse nijwi ryuruhu kumoko yose yuruhu.Alpha-Arbutin kandi igabanya ibibara byumwijima kandi yujuje ibisabwa byose kugirango igezweho igaragaze uruhu kandi igabanya uruhu.

Ibicuruzwa

Alpha-Arbutinni biosynetike glycoside ifite uburyo bwiza bwo kumurika uruhu kubwijwi ryuruhu rwiza.Irashobora guhagarika neza synthesis ya melanin mukubuza tyrosinase, iyi ngaruka iragerwaho nubwo haba hake cyane. AlphaArbutinYerekana tirozinase itangaje kandi ikora inshuro icyenda kurenza Beta-Arbutin.Indangagaciro nkeya IC50 yerekana imbaraga zaAlpha-Arbutin.Ingaruka zidasanzwe za Alphar-Arbutin ziterwa nubusabane bwuzuye kurubuga rukora rwa tyrosinase. Alpha-Arbutin ni amazi ashonga kandi byoroshye kwinjizwa mubice byamazi yo kwisiga.Irahamye kurwanya hydhydrolysis nkuko byageragejwe muri pH kuva kuri 3.5 - 6.6.Icyifuzo cyo kwibandaho: 0.2% mugihe cyateguwe hamwe na exfoliant cyangwa penetration yongera, ubundi bigera kuri 2%.
