Abstract
Description
Technical Field
[0001] The present invention belongs to the field of medicine or personal care products, and specifically relates to a composition with moisturizing, repairing, firming, anti-wrinkle and other effects and its application. Background Art
[0002] With increasing demands for skin care, especially in modern life, the skin is prone to dryness, dehydration, sensitivity, and sagging due to a variety of factors, including environmental factors and unhealthy lifestyles. To address these issues, moisturizing, repairing, firming, and anti-wrinkle products are gaining widespread attention. The primary purpose of moisturizing and repairing is to provide the skin with adequate moisture and nutrients, maintaining its water-oil balance and keeping it healthy, smooth, and elastic. Moisturizing and repairing also helps strengthen the skin's barrier function, protecting it from external irritants and reducing skin damage and allergic reactions. Firming and anti-wrinkle products, on the other hand, combat wrinkles and sagging caused by natural aging and photoaging. Wrinkles are primarily caused by a decrease in collagen fibers, disrupted collagen fiber bundles, elastin denaturation, basal membrane damage, and angiogenesis, which in turn lead to water loss and wrinkles. In the pharmaceutical and personal care market, moisturizing, repairing, firming, and anti-wrinkle products are plentiful, including creams, lotions, serums, and facial masks. However, many raw materials only have a single function, so various components must be formulated to achieve the desired effect. Many components cannot be combined with other ingredients, resulting in limitations in the form of pharmaceutical or personal care compositions.
[0003] To overcome the limitations of existing technologies, researchers have begun to focus on the potential applications of annexins in skin care. Annexins are a class of calcium-dependent, phospholipid-binding proteins widely distributed throughout the body, playing important roles in cell signaling, inflammatory responses, cell growth, and differentiation. Annexin A5 (AnxA5) has attracted particular attention. Annexin A5 is a calcium-dependent, phospholipid-binding protein widely present in various cell types. It plays a crucial role in cell signaling, inflammatory responses, apoptosis, and cell differentiation. During apoptosis, Annexin A5 binds to phosphatidylserine (PS) exposed on the outside of the cell membrane, preventing phagocytes from recognizing apoptotic cells and thereby regulating the apoptotic process.
[0004] Annexin A5 has attracted considerable attention for its role in drug delivery. It significantly enhances the absorption and transmembrane transport of liposome-based drug delivery systems, enabling topical delivery of physiological concentrations of drugs and improving drug penetration in the skin (Davies et al., 2014). Annexin A5 also promotes rapid cell membrane repair by forming protective two-dimensional ribbon-like structures, exhibiting significant anti-inflammatory and anti-apoptotic effects, which are crucial for maintaining skin cell function (Bouter et al., 2015). Annexins interact with various intracellular biomolecules to exert their roles in signal transduction and cell protection. They can be incorporated into artificial liposomes or lipid vesicles, enabling better study and observation of their structure and function (Jeong et al., 2020). Application studies have shown that annexin A5 can maximize the protection of skin cells and maintain intact cellular function, demonstrating its potential in addressing skin dryness, allergies, and wrinkles caused by cellular dysfunction. Furthermore, peptide complexes, as derivatives of annexins, have been shown to promote the expression of basement membrane proteins, such as collagen XVII and laminin, in human epidermal keratinocytes, thereby improving the structural integrity and mechanical stability of the skin (Gomes et al., 2020). The application of these proteins in pharmaceuticals or personal care products, particularly through biotechnology extraction and utilization, such as fermentation processes or genetic engineering, can significantly enhance the anti-aging effects of pharmaceuticals or personal care products.
[0005] In summary, the application of annexins, particularly annexin A5, in pharmaceuticals and personal care products holds broad promise. Through advanced biotechnology and delivery systems, annexins and their related active ingredients play a significant role in enhancing the efficacy of pharmaceuticals and personal care products, simplifying formulation complexity, and meeting consumers' multifunctional skin care needs. The present invention aims to leverage the multiple benefits of annexin A5 to develop a pharmaceutical or personal care product with moisturizing, repairing, firming, and anti-wrinkle properties. This approach addresses the high demands of modern consumers for pharmaceuticals and personal care products, addresses skin problems such as dryness, allergies, sagging, and wrinkles, and provides consumers with a more comprehensive and effective skin care solution. Summary of the Invention
[0006] A first aspect of the present invention provides a use of an annexin in the preparation of a pharmaceutical composition or a personal care composition, wherein the pharmaceutical composition or the personal care composition has one or more of the following effects:
[0007] (a) Moisturizing;
[0008] (b) Repair;
[0009] (c) firming;
[0010] (d) Anti-wrinkle.
[0011] Annexins are a widely distributed class of calcium-dependent phospholipid-binding proteins. Based on molecular phylogenetic and comparative genomic analyses, this protein family has been uniformly designated as annexin (abbreviated as Anx), followed by capital letters representing the respective species: A, B, C, D, and E, representing vertebrates, invertebrates, fungi and myxomycetes, plants, and protists, respectively. Currently, the Anx A family has 12 members: A1-A11 and A13 (A12 is unassigned).
[0012] Annexin plays an important role in cell biology. It can bind to phosphatidylserine in the cell membrane and participate in various cellular processes, including membrane repair, signal transduction, cell division, inflammatory response, etc.
[0013] In one embodiment, the annexin protein of the present invention is annexin A (Anx A).
[0014] In one embodiment, the Annexin A is Annexin A5.
[0015] In one embodiment, the Annexin A5 is human Annexin A5.

[0023] Preferably, the annexin protein includes a wild type or a mutant type.
[0024] Annexin A5 (AnxA5) is widely distributed in various tissue cells of the body. In vitro studies have found that AnxA5 has multiple functions such as anti-phospholipase, anti-coagulation, and anti-kinase. It is currently mainly used as a reagent for detecting cell apoptosis.
[0025] During apoptosis, Annexin A5 recognizes and binds to phosphatidylserine exposed on the outer surface of the cell membrane, thereby preventing phagocytes from recognizing apoptotic cells and regulating the apoptotic process. As a marker of apoptosis, it is widely used in scientific research and medicine, and is particularly important in cancer research and treatment. Annexin A5 also plays a role in blood coagulation and anti-inflammatory responses, stabilizing cell membranes and preventing leakage of cellular contents, thereby reducing inflammation.
[0026] The applications of annexins are not limited to their anti-apoptotic and anti-inflammatory properties but also include their potential role in drug delivery systems. For example, annexins can be used to develop novel drug carriers to improve drug targeting and bioavailability. By binding annexins to drugs, drug trafficking and release within cells can be enhanced, thereby improving therapeutic efficacy.
[0027] In the field of medicine and personal care products, the present invention has studied in detail the effects of Annexin A5 as an active ingredient, which reduces skin damage caused by environmental factors and aging by enhancing the stability and repair capacity of cell membranes. It also promotes skin cell renewal and regeneration by regulating intercellular signaling, thereby achieving firming and anti-wrinkle effects. Compared to other skincare ingredients, Annexin A5 is multifunctional and highly effective, capable of simultaneously addressing multiple skin concerns, restoring skin to a healthy, smooth, and elastic state.
[0028] The present invention utilizes these biological properties of annexin A5 to develop pharmaceuticals or personal care products with moisturizing, repairing, firming, and anti-wrinkle properties. The annexin proteins useful in the present invention are not particularly limited and can be derived from any organism, preferably from mammals (such as primates), more preferably from humans, monkeys, or mice. Furthermore, it should be understood that "annexin" includes wild-type and mutant (including truncated) annexins, as long as the mutant annexin retains or maintains the detoxification activity of the wild-type annexin.
[0029] In summary, Annexin A5 has broad application prospects in medicines or personal care products. By combining advanced biotechnology and delivery systems, it can significantly enhance the efficacy of medicines or personal care products and meet consumers' growing demand for multifunctional skin care.

[0154] The present invention will be further described below in conjunction with specific examples. It should be understood that these examples are intended to illustrate the present invention only and are not intended to limit the scope of the invention. The experimental methods in the following examples, for which specific conditions are not specified, are generally based on conventional conditions or the conditions recommended by the manufacturer. Unless otherwise stated, percentages and parts are calculated by weight.
[0155] Unless otherwise specified, the experimental materials and reagents used in the following examples can be obtained from commercial channels.
[0156] Example 1. Cytotoxicity experiment
[0157] This study aimed to evaluate the cytotoxicity of recombinant annexin A5 (AnxA5) at various concentrations in human dermal fibroblasts (hDF). Cell viability was measured to determine the effects of AnxA5 at different concentrations on cell survival, thereby ensuring its safety in pharmaceutical, personal care, and other applications.
[0158] Reagents and materials:
[0159] Cell line: human dermal fibroblasts (hDF);
[0160] Reagents: DMEM (GIBCO), FBS (GIBCO), PBS (GIBCO), 0.25% trypsin (GIBCO), CCK8 (DOJINDO, Japan), etc.
[0161] The experiment included the following groups:
[0162] Blank control group (CON.): only an equal amount of PBS was added to the culture medium.
[0163] Experimental group: Different concentrations of AnxA5 were added to the culture medium, including 5 mg / mL, 1 mg / mL, 500 μg / mL, 50 μg / mL, 5 μg / mL, 1.6 μg / mL, and 500 ng / mL.
[0164] Experimental process:
[0165] Human skin fibroblasts (hDF) were cultured at a rate of 3*10 4 Cells were seeded into 96-well cell culture plates at a density of 100 cells / mL. After 24 hours, the culture medium was replaced with medium containing various concentrations of recombinant A5 protein. An equal volume of PBS was added to the blank control group and incubated for a further 72 hours. CCK8 was then added and incubated in a CO2 incubator for 2 hours. The absorbance was measured at 450 nm using a microplate reader. Cell viability was calculated.
[0166] Cell viability (%) = (A1-A) / (A0-A) × 100%
[0167] Where A1 represents the absorbance of the sample group, A represents the absorbance of the cell-free CCK8 culture medium solution, and A0 represents the absorbance of the blank control group. Statistical analysis was performed using GraphPad Prism, and a sample-cell viability histogram was plotted.
[0168] Result analysis: Figure 1The figure shows the cell viability of different experimental groups. As shown, different concentrations of recombinant annexin A5 (AnxA5) have different effects on human dermal fibroblasts (hDF). A high concentration (5 mg / mL) of AnxA5 significantly reduced cell viability compared to the blank control (CON.), indicating cytotoxicity. Intermediate concentrations (1 mg / mL to 5 μg / mL) and low concentrations (1.6 μg / mL to 500 ng / mL) had little effect on cell viability or no significant toxicity. In particular, within the concentration range below 1 mg / mL, cell viability remained around or above 100%, indicating that AnxA5 has no significant cytotoxicity to cells at these concentrations.
[0169] This example demonstrates that recombinant annexin A5 has no significant cytotoxicity to human dermal fibroblasts (hDF) at concentrations below 1 mg / mL, providing a scientific basis for its safe use in pharmaceuticals, personal care products, and other biological applications.
[0170] Example 2. Preparation of Essence for Human Efficacy Testing
[0171] The serum was prepared according to the following formula: Annexin A5, water, 1,3-butylene glycol, glycerol, 1,3-hexanediol
[0172] (1) Materials:
[0173] Water (Aqua) (70-80%);
[0174] 1,3-Butylene Glycol: As a solvent and humectant, the usage amount is 4% (w / v) (2-5%);
[0175] Glycerin: As a moisturizer, the usage amount is 3% (w / v) (2-5%);
[0176] 1,3-Hexanediol: acts as a solvent and humectant, also acting as a preservative. The usage level is 1% (w / v) (1-2%).
[0177] Annexin A5: As an active ingredient, the usage amount is 0.1% (w / v) (0.01-1%).
[0178] (2) Preparation steps:
[0179] Step 1: Prepare and heat the water phase ingredients
[0180] In a clean container, combine water, 1,3-butylene glycol, glycerin, and 1,3-hexanediol. Heat the mixture to 75°C to 80°C to ensure all ingredients are completely dissolved.
[0181] Step 2: Add active ingredients
[0182] The mixture is cooled to 40°C and annexin A5 is added. This step needs to be performed at a lower temperature to prevent the active ingredient from being denatured by heat.
[0183] Step 3: Homogenization and filling
[0184] Use a high shear homogenizer to process the mixture to ensure that all ingredients are evenly mixed to form a uniform serum. Fill the serum into sterile containers to prevent contamination. If necessary, pH adjusters (such as citric acid) and preservatives can be added to the formula to make it more suitable for skin use.
[0185] Example 3. Human efficacy evaluation experiment
[0186] This example aimed to evaluate the moisturizing, repairing, firming, and anti-wrinkle effects of a serum containing recombinant annexin A5 (AnxA5) on the skin, as well as its effects on improving skin color and pigmentation, through human efficacy evaluation. A comprehensive evaluation of the serum's moisturizing, repairing, firming, and anti-wrinkle effects, as well as its effects on improving skin color and pigmentation, was conducted using test products in subjects, combined with instrumental testing and subjective evaluation.

[0209] Note: D0 is the 0th day from the start of the test, D14 is the 14th day from the start of the test, and the same below.
[0210] 3.6 Statistical Methods: SPSS statistical analysis software was used. If the values showed a normal distribution, the T-test was used for statistical analysis; if the values showed a non-normal distribution, the rank sum test was used for statistical analysis. Two-tailed tests were used, with an α level of 0.05.
[0211] 3.7 Questionnaire Result Statistical Method and Safety Evaluation Method
[0212] 3.7.1 Statistical method for questionnaire results: The percentage of people with a score ≥ 4 was calculated; the binomial distribution method was used for statistical analysis, with the expected value set at 0.5 and the significance level at α = 0.05. If the P value was less than 0.05, it indicated a significant difference.
[0213] 3.7.2 Safety evaluation adopts statistical descriptive method: analyzing the degree and duration of adverse events case by case.
[0214] The formula for calculating the rate of change is as follows:
[0215] Δ(difference) after using the test product for 14 days = D14 - D0
[0216] △ (difference) after using the test product for 28 days = D28 - D0
[0217] △ (difference) after using the test product for 56 days = D56 - D0
[0218]
[0219]
[0220]
[0221] In the formula, D0 is the basic value of skin parameters before using the test product in the test area.
[0222] D14 - Skin parameter values after the test area has been treated with the test product for 14 days.
[0223] D28 - Skin parameter values after the test area has used the test product for 28 days.
[0224] D56 - Skin parameter values after the test area has used the test product for 56 days.
