Description

Composition and application thereof in preparation of anti-glycosylation cosmetics

Technical Field

The invention relates to the technical field of cosmetics, in particular to a composition and application thereof in preparing an anti-glycosylation cosmetic.

Background

With age, all organs of the human body undergo degradation, aging changes, and the skin also undergoes great changes in structure and function. Today, most scholars differentiate skin aging into natural aging and photoaging. Wherein natural aging is a natural, unavoidable aging process that occurs in the skin as the human body ages. In the natural aging process, the epidermis is often thinned, the network ridges become flattened, the shared interface area at the junction of the epidermis and the dermis is reduced, and the skin fragility is increased. In the skin, the structure and number of different cells are changed, and the gene expression, biological factors and protein synthesis capacity are reduced. The skin collagen grid becomes compact and the elastic fiber is obviously decomposed, so that the skin is loose, sagged, wrinkled and the like. At the same time, the content of matrix proteoglycan is reduced, so that the hydration capability is reduced, and the skin aging appearance is formed.

The natural aging of skin is a complex process, and there are mainly 5 mechanisms of aging process, namely: oxidative stress, mitochondrial damage, cellular senescence, contaminant damage, and skin glycation. Among them, skin glycation has been widely focused in recent years, and has become a research hotspot. Glucose or other carbohydrate molecules in the body adhere to proteins by mistake, causing protein denaturation, a detrimental reaction that contributes to aging. Specifically, the addition of the reducing amino group at the end of the macromolecule and the aldehyde group in sugar molecules such as glucose form a reversible Schiff base, and the reaction is rapid and highly reversible; after a few days, the unstable Schiff base gradually undergoes a rearrangement reaction and forms a relatively stable aldehyde amine product, and the aldehyde amine product accumulates on the protein to form an early glycosylation product; finally, the product undergoes a series of dehydration and rearrangement reactions to produce highly reactive carbonyl compounds, such as methylglyoxal, which react with the free amino groups of the protein to produce advanced glycation end products (AGEs). The AGEs generated can be combined with free amino groups on adjacent proteins in a covalent bond mode to form an AGE cross-linked structure.

AGEs and their protein addition products are very stable and irreversible, thus disrupting normal protein structure and function. For the human body, glycosylation can thicken and harden the arterial wall, and is easy to break, thereby causing hypertension, heart disease, kidney disease and cerebrovascular disease; can cause adjacent lens proteins to twist together, causing clouding and degeneration of the lens, and causing senile cataract. For human skin tissues, the enzyme activity function becomes low in the glycosylation process, and the oxidative stress sensitivity of cells is enhanced, so that the cells are more vulnerable to damage; in the early glycosylation product forming process, the composition can interact with various cell surface AGE receptors, so that oxidative damage is easy to trigger, and simultaneously, the increase of free radicals is accompanied with inflammatory reaction, so that the balance of the whole physiological process is broken, and metabolism is disturbed. And when the final product of late glycosylation is formed, the free amino groups on proteins important to the skin, such as collagen and elastin, are combined with covalent bonds to form an AGE cross-linked structure. The reaction is irreversible, so that the density of a crosslinked network is improved, and the chemical structure and corresponding biomechanical and physiological functions of the crosslinked network are destroyed. From the appearance of the skin, yellowing, dullness, sagging, wrinkles, etc. of the skin can be observed.

Currently, the mechanisms of the aging process are subdivided, so that the anti-aging and skin repair are performed from different subdivision mechanisms. For the anti-glycosylation process, a single strategy is usually adopted at present, only the final product AGE is focused, and the AGE is decomposed by adopting medicines, so that only partial inhibition effect is usually achieved, and the whole effect is ignored; or limited to the ways of scavenging free radicals, resisting oxidation, etc., and generally deal with symptoms at a certain reaction node, the whole reaction process cannot be comprehensively considered, so that the final anti-glycosylation effect is poor.

Glycosylation is a long-term process with a time effect, with different characteristics at each stage. The Schiff base synthesis stage and the glycosylation early-stage product synthesis stage are characterized in that the generated product has inhibitive performance and reversibility, and the extracellular matrix microenvironment can be changed through the introduction of active substances, so that the inhibition and reversal reaction are carried out; the crosslinking density of fibrin and elastin is obviously improved in the later-stage advanced glycosylation end product forming stage, and the process is difficult to reverse, but can be relieved and partially repaired by means of protein binding competition, degradation and the like. In view of this, in the strategy of considering the anti-glycosylation, the whole process should be comprehensively considered, and according to the characteristics of different stages, appropriate functional substances are respectively adopted to play roles of prevention, reversion and repair; with glycosylation sequence as core, anti-glycation and skin repair are performed in multiple dimensions.

The experimental method comprises the following steps:

1. PBS buffer (pH 7.4) was prepared

2. The glucose concentration is 200mM, the final concentration of bovine serum albumin is 40g.L-1, and the reaction system is subjected to antibiosis by using 2000u.L-1 green streptomycin double-antibody liquid. Incubation was carried out at 37℃for 2-8 weeks, and the effect of glucose on the non-enzymatic glycation reaction of the protein was observed.

3. Determination of early glycated proteins (fructosamine): after incubation of the reaction system at 37℃for 2 weeks, 0.05ml of the reaction mixture was taken, 4ml of NBT was added, the reaction was terminated with 0.1ml of 15% acetic acid and a cold bath after incubation at 37℃for 15 minutes, and absorbance was measured at a wavelength of 530 nm.

TABLE 2

Glycosylation products	Fructosamine product inhibition (%)	Inhibition of AGEs products (%)
			Control sample-1	1.57	0.47
Control sample-2	50.79	19.43
			Control sample-3	60.73	50.24
Control sample-4	28.80	20.38
			Control sample-5	66.49	64.45
Control sample-6	32.46	14.69
			Control sample-7	9.95	9.48
Example sample-1	71.20	67.77
			Example sample-2	82.72	81.52
Example sample-3	94.24	89.57

Conclusion: as can be seen from the control sample-2, the production of fructosamine products was effectively inhibited at the early stage when only glycosylation reaction was prevented, and the inhibition rate was 50.79%, but the production of AGEs, which was a saccharification product, was further increased with the increase of time, and the inhibition rate was decreased. From the control sample-5, it was found that fructosamine and AGEs can be effectively inhibited from being produced when both prevention and repair are simultaneously performed, and the inhibition rates are 66.49% and 64.45%, respectively. It can be seen from example-2 that fructosamine and AGEs can be more effectively inhibited from being generated when three directions of prevention, reversion and repair are combined, and inhibition rates are 82.72% and 81.52%, respectively.

The combination effect is calculated by adopting a golden average method, and the calculation formula is q=E _A+B /(E _A +E _B -E _A *E _B ) Wherein q is increased by more than 1.15 to 20. Control 2 (E) _A ) With control 6 (E) _B ) Comparative example 2 (E) _A+B ) Q values of 1.24 and 2.60 for the inhibited fructosamine and AGEs products, respectively, indicate that the active combination of control 2 has an enhanced active effect compared to the active combination of control 6. Control 3 (E) _A ) With control sample 4 (E) _B ) Comparative example 2 (E) _A+B ) Q values of 1.15 and 1.35 for the inhibited fructosamine products and AGEs products, respectively, were obtained, indicating that the active combination in control 3 had an enhanced active effect with the active combination of control 4.
