The application of paradime thylaminobenzaldehyde thiosemicarbazones in skin-lightening cosmetic
Technical field
The present invention relates to a kind of paradime thylaminobenzaldehyde thiosemicarbazones, especially relate to the paradime thylaminobenzaldehyde thiosemicarbazones and be applied to skin-lightening cosmetic as brightening agent as tyrosinase inhibitor.
Background technology
Tryrosinase extensively is present in the organism, be the biosynthetic key enzyme of melanocyte (Mayer AM, Harel E.Phenoloxidases and their significance in fruit and vegetables.Food Enzymology, Fox P F.Ed, Elsevier; London, 1998,373-398) in organism, tryrosinase at first hydroxylating tyrosine generates L-DOPA, and oxidation L-DOPA generates the DOPA quinone then, and the DOPA quinone forms melanin through a series of enzyme catalysiss and non-enzymatic catalysis reaction again.Therefore, tryrosinase is the synthetic rate-limiting enzyme of melanocyte, it is active relevant with the melanocyte synthetic quantity, can by regulate and control its vigor regulate and control the growing amount of melanocyte (Friedman M.Food browning and its prevention:an overview[J] .J.Agric.Food Chem., 1996,44 (3): 631-653).At present, the whitening composition in the skin-lightening cosmetic mainly carries out the screening of whitening agent as target spot with tryrosinase.The extract of whitening agent that circulates on the market such as kojic acid, Arbutin and some Chinese herbal medicine all is tyrosinase inhibitors.But existing whitening agent effect is not very good, and some also has certain side effect, therefore, presses for the Synthetic inhibitor of melanin that research efficiently has no side effect.
Studies show that (thiosemicarbazone) compound has multiple biological activitys such as antibacterium, tuberculosis, antiviral, antitumor.(Dobek AS, Klaman DL, Dikson ET, et al.Inhibition of clinically significant bacterial organismsin vitro by 2-acetypyridine thiosemicarbazones[J] .Antimicrob Agents Chemother, 1980,18:27; Shukla HK, Desai NC, Astik RR, et al.Studies on some thiosemicarbazones and1,3,4-thiadiazolines as potential antitubercular and antibacterial agents[J] .J Indian Chem Soc, 1984; 61 (2): 168-169; Wilson HR, Revankar GR, Tolman RL.In vivo activity of certainthiosemicarbazones against Trypanosoma cruzi[J] .J Med Chem, 1974,17 (7): 760-761.) still, it does not have report as yet to tryrosinase and the synthetic inhibitory action of melanin, and this compounds being applied in cosmetics still belongs to blank both at home and abroad.Simultaneously, for designing better and the development of new Synthetic inhibitor of melanin, be necessary to inquire into the inhibitory action mechanism of inhibitor to tryrosinase.At present, the brightening agent of main skin-lightening cosmetic generally adopts natural extract on the market, but the natural extract complicated component causes and extracts and processing difficulties.And the brightening agent of chemosynthesis helps producing in enormous quantities, and its processing technology is simple, and whitening effect is quick and remarkable, but has the problem of safety easily, can not be ignored.
Summary of the invention
Chemical compound-paradime thylaminobenzaldehyde the thiosemicarbazones that the objective of the invention is to have efficient restraint of tyrosinase vigor is as the application of brightening agent in the preparation cosmetics.
Another object of the present invention provides a kind of chemical compound-paradime thylaminobenzaldehyde thiosemicarbazones that will have an efficient restraint of tyrosinase vigor as skin-lightening cosmetic of brightening agent and preparation method thereof.
The chemical structural formula of paradime thylaminobenzaldehyde thiosemicarbazones of the present invention is:
Paradime thylaminobenzaldehyde thiosemicarbazones of the present invention is a kind of chemical compound with efficient restraint of tyrosinase vigor, can be used as brightening agent and is used to prepare cosmetics.
Below providing the chemical compound-paradime thylaminobenzaldehyde thiosemicarbazones that will have efficient restraint of tyrosinase vigor consists of as the raw material of a kind of wrinkle removal whitening astringent of brightening agent:

Plant essence can be selected a kind of in geraniol, Flos Rosae Rugosae quintessence oil, Flos Jasmini Sambac quintessence oil, Garden lavender quintessence oil, rosemary ethereal oil, Flos Pelargonii quintessence oil, clove oil, the lemon extract wet goods for use.
Antiseptic can be selected at least a in Buddhist nun uncle tortoise beetle ester, Ethyl Hydroxybenzoate, the Ni Baijin propyl ester etc. for use.
Below provide the chemical compound-paradime thylaminobenzaldehyde thiosemicarbazones that to have efficient restraint of tyrosinase vigor preparation method, the steps include: as a kind of wrinkle removal whitening astringent of brightening agent
1) it is soluble in water to take by weighing the marine fish collagen peptide by said ratio, marine fish collagen protein peptide solution, be designated as solution A;
2) take by weighing antiseptic and the paradime thylaminobenzaldehyde thiosemicarbazones is dissolved in dehydrated alcohol, solution B;
3) in solution B, add glycerol and propylene glycol, get solution C;
4) solution A and solution C are mixed, add the water mixing, get solution D;
5) add plant essence in solution D, mixing gets target product wrinkle removal whitening astringent.
At least a with in distilled water, deionized water and the pure water etc. of described wet concentration.
Paradime thylaminobenzaldehyde thiosemicarbazones of the present invention is as follows as a kind of effect of cosmetics brightening agent:
The paradime thylaminobenzaldehyde thiosemicarbazones at room temperature can be dissolved in ethanol well, is easy to be applied in the cosmetics.Adopt the enzyme dynamics method, studies show that by inhibition effect tryrosinase, thiosemicarbazides, paradime thylaminobenzaldehyde and paradime thylaminobenzaldehyde thiosemicarbazones are respectively 2.54mmol/L to active half suppression ratio of Mushroom Tyrosinase, 0.665mmol/L, 2.7 μ mol/L (see figure 1)s.With the tryrosinase of slightly carrying mice B16 cell is object of study, then half suppression ratio of paradime thylaminobenzaldehyde thiosemicarbazones is 134.5 μ mol/L, and when paradime thylaminobenzaldehyde concentration was lower than 7.5mmol/L, its suppression ratio to enzymatic activity still only had 54.5% (see figure 2).Double suppression ratio embodied the inhibition strength of inhibitor to enzyme, and half suppression ratio is more little, illustrates that inhibition strength is strong more.At present, detection compound becomes the index of this compounds of measurement as the whitening effect of cosmetics brightening agent to the inhibition activity of tryrosinase.Chemical compound is big more to the inhibition strength of tryrosinase, shows that its whitening effect is good more.Can be shown that by experimental result the paradime thylaminobenzaldehyde thiosemicarbazones has very strong inhibitory action to tryrosinase, its inhibition strength strengthens greatly with respect to its two raw materials.Show by experimental result, the paradime thylaminobenzaldehyde thiosemicarbazones is the reversible inhibitor (see figure 3) of this enzyme, and by this chemical compound the double-reciprocal plot (see figure 4) of the inhibition mechanism research of tryrosinase is shown that this chemical compound is the mixed-type inhibitor of tryrosinase.And can try to achieve the inhibition constant (K of chemical compound by the straight slope of Fig. 5 and Fig. 6 respectively to resolvase
I) be 1.78 μ mol/L, chemical compound is to the inhibition constant (K of resolvase
I) be 6.43 μ mol/L.Chemical compound to the inhibitory action mechanism of Mushroom Tyrosinase referring to table 1.
