Definitions
- the present invention relates to the technical field related to skin repair, and more particularly, the present invention provides a hypoxia-induced targeted anti-aging repair method.
- Aging represents all the physiological changes in the body that occur over time, and the state and speed of aging varies from individual to individual and is affected by a variety of causes. Even within an individual, aging manifests differently for each organ, so individual-oriented aging studies have limitations. As the first and most easily detected aging process in the human body, skin aging is the comprehensive result and external manifestation of the overall function beginning to age.
- Skin aging reduces the skin's ability to protect and regulate the body.
- the skin cannot adapt to changes in the internal and external environment, and changes in overall appearance such as color, lustre, shape, texture, etc., will lead to fine wrinkles, decreased elasticity, and loose skin. , Rough, yellowish or grayish-yellow skin discoloration, telangiectasia, formation of pigmented spots, etc.
- Three major skin changes can induce the above aging phenomena: thinning of the epidermis leads to skin sensitivity and hyperpigmentation; thinning of the dermis leads to increased fine lines and dark lines and decreased skin elasticity; cell dehydration leads to dry and rough skin.
- the present invention realizes the targeted and precise delivery of substances and energy, as well as the precise induction and activation of damaged and aging skin cells in a hypoxic environment, and uses functional factors to synergize with it. In this process, it can effectively affect cell growth, proliferation, differentiation and damage repair, protect cells from free radical damage, inhibit lipid It can also improve the microcirculation of the skin, promote the metabolism of the skin, better promote the production of collagen, and solve the problem of skin aging.
- a first aspect of the present invention provides a hypoxia-induced targeted anti-aging repair method, including the processes of channel recognition (Channel), vesicle transport (Transport), induced activation (Activation) and damage repair (Repair).
- Channel channel recognition
- Transport vesicle transport
- Activation induced activation
- Repair damage repair
- Transmembrane transport can communicate the connections between inside and outside cells and between various organelles in cells, ensure the normal exchange of substances in life activities such as metabolism, and is also the basis of biofilm energy conversion and information transmission. It is divided into two categories, one is the transmembrane transport of small molecules and ionic substances, including active transport and passive transport, and the other is the membrane vesicle transport of macromolecules and granular substances, including endocytosis and exocytosis.
- the "channel recognition" described in the present invention includes the transmembrane transport of small molecular substances, and according to the type of substances transported across the membrane, the channel recognition includes small molecular channel recognition; wherein the small molecules such as water molecules, small molecules of collagen etc.; and moisture is very important for the skin, and the lack of human skin moisture will inevitably cause problems such as skin dryness and aging; preferably, in the present invention, the water molecule channel is studied.
- the present invention utilizes a natural moisturizing factor to increase the recognition and transport of water on the skin surface by skin cell aquaporins
- the moisturizing factor is a substance well known in the art, such as selected from hyaluronic acid, collagen, vitamins, hyaluronic acid, cholesterol, fatty acids, phospholipids , linoleic acid, glycosaminoglycan, glycerin, amino acids, polyamino acids, amino acid surfactants, pyrrolidone carboxylic acid and its salts, N-acetylglucosamine, animal and plant polysaccharides, coenzyme Q10, rice flour, white Gelatin, oligosaccharides, monosaccharides, saponins, vegetable peptides, phospholipids, sericin, albumin, chondroitin, ceramides, collagen, chitin and chitosan, etc.
- amino acids for example, aspartic acid, threonine, serine, glutamic acid, citrulline, proline, glycine, alanine, cysteine, valine, methionine, isoleucine acid, leucine, tyrosine, phenylalanine, tryptophan, lysine, ornithine, histidine, arginine, etc.
- animal and plant polysaccharides (1) as plant polysaccharides, for example, guar gum, locust bean gum, quince seed gum which are seed polysaccharides, carrageenan which is seaweed polysaccharide, alginic acid , are resin polysaccharides of arabic rubber, tragacanth, etc.; (2) as animal polysaccharides, such as collagen peptides extracted from fish intestines and fish scales.
- saponins for example, tea, licorice, ginseng, bamboo ginseng, soybean, Bupleurum, horse chestnut, loofah, Polygala, bellflower, Polygala, Ophiopogon, Mutong, thyme, Achyranthes, Substances derived from plants contained in smilax smilax and the like.
- the present invention preferably uses hyaluronic acid as a moisturizing factor; in order to further promote skin metabolism, cell hydration and skin elasticity, the hyaluronic acid selected in the present invention includes high molecular weight hyaluronic acid, medium molecular weight hyaluronic acid, and hyaluronic acid.
- hyaluronic acid and low molecular weight hyaluronic acid the synergistic effect of three different types of hyaluronic acid can promote the synthesis of collagen and ceramide, as well as the migration and proliferation of skin cells, and can also lock moisture, replenish moisture and The effect of nourishing the stratum corneum can also regulate the activity of immune cells.

Description
本发明涉及皮肤修复相关的技术领域,更具体地,本发明提供一种低氧诱导靶向抗衰修护方法。
衰老表示随着时间流逝而出现的身体的所有生理变化,而衰老状况和速度因个体情况而不同,并且受到多种原因的影响。即使在一个个体中,衰老对于每个器官也表现出不同的状况,因此面向个体的衰老研究具有局限性。皮肤的衰老作为人体最先和最容易被察觉的衰老过程,是整体机能开始走向老化的综合结果和外部体现。
皮肤衰老使得皮肤对机体的防护能力、调节能力等减退,由此皮肤不能适应内外环境的变化,出现颜色、色泽、形态、质感等外观整体状况的改变,会出现细小皱纹、弹性下降、皮肤松弛、粗糙、淡黄或灰黄色的皮肤变色、毛细血管扩张、色素斑形成等。三大皮肤改变可诱使以上衰老现象的产生:表皮变薄导致皮肤敏感和色素沉着;真皮变薄导致细纹暗纹增多和皮肤弹性下降;细胞失水导致皮肤干燥粗糙。
而皮肤细胞的物质和能量供应不足,致使皮肤损伤无法被及时修复,是造成皮肤衰老的主要原因,当细胞生长和修复所需的各种养分、生长因子和氧气供应不足时,皮肤自我修复和新生的能力会逐渐减弱,皮肤就会失去活力,目前皮肤修护的相关研究中,大部分会采用各种营护肤组分实现对皮肤的修护,但是实际使用过程中,由于较难保证营养护肤组分的运输有效性以及其对靶向细胞的修复、传递精准性,导致皮肤对护肤组分的有效成分的利用率低,不能很好地对损伤和衰老皮肤细胞进行有效修复与保护。
发明内容
本发明为解决上述问题,即皮肤抗衰老以及修护过程中,实现物质与能量的靶向精准送达,以及对低氧环境下损伤和衰老皮肤细胞的精准诱导激活,利用功能因子与之协同作用,实现对损伤、衰老细胞的高效、精准修复,实现有效组分的高效利用,在该过程中能有效影响细胞生长、增殖、分化以及损伤修复,保护细胞免受自由基的伤害,抑制脂质过氧化、保护生物膜结构的完整性和皮肤脂质 屏障的完整性;也能够改善皮肤微循环,促进皮肤的新陈代谢,更好促进胶原蛋白的产生,解决皮肤衰老问题。
本发明的第一方面提供了一种低氧诱导靶向抗衰修护方法,包括通道识别(Channel)、囊泡转运(Transport)、诱导激活(Activation)以及损伤修复(Repair)的过程。
在皮肤保养以及修护过程中所需要的物质,例如水分、生长因子、氧气等,进入人体被吸收从而发挥其应有的功能是需要多种形式的跨膜运输协同来实现的。跨膜运输可以沟通细胞内外及细胞内各细胞器之间的联系,保证新陈代谢等生命活动中的正常物质交换,也是生物膜能量转换和信息传递等功能的基础;而物质跨膜运输的方式可分为两大类,一类是小分子和离子物质的跨膜运输,包括主动运输和被动运输,另一类是大分子和颗粒物质的膜泡运输,包括胞吞作用和胞吐作用。
在本发明中所述的“通道识别”包括小分子物质的跨膜运输,根据跨膜运输的物质种类,通道识别包括小分子通道识别;其中所述的小分子例如水分子、小分子胶原蛋白等;而水分对于皮肤来说是至关重要的,人体皮肤水分的缺失会不可避免地引起皮肤干瘪、衰老等问题;优选地,本发明中针对水分子通道进行了研究,通道识别过程中,利用天然保湿因子促进水分子通道的开放,调节基础代谢,提高了皮肤对水分的吸收能力,同时调节了细胞的基础代谢环境,可以促进后源营养物质的进入。
本发明利用天然保湿因子增加皮肤细胞水通道蛋白对皮肤表面水分的识别与运输,保湿因子为本领域熟知的物质,例如选自透明质酸、胶原蛋白、维生素、玻尿酸、胆固醇、脂肪酸、磷脂质、亚麻油酸、葡萄胺聚糖、甘油、氨基酸、聚氨基酸、氨基酸类表面活性剂、吡咯烷酮羧酸及其盐、N-乙酰氨基葡糖、动植物性多糖类、辅酶Q10、米粉、白明胶、低聚糖、单糖类、皂角苷类、植物性肽、磷脂、丝胶、清蛋白、软骨素、神经酰胺、胶原、几丁质及壳聚糖等。
作为氨基酸,例如天冬氨酸、苏氨酸、丝氨酸、谷氨酸、瓜氨酸、脯氨酸、甘氨酸、丙氨酸、半胱氨酸、缬氨酸、甲硫氨酸、异亮氨酸、亮氨酸、酪氨酸、苯基丙氨酸、色氨酸、赖氨酸、鸟氨酸、组氨酸、精氨酸等。
作为动植物性多糖类,(1)作为植物性多糖类,例如种子多糖类的瓜尔豆胶、 刺槐豆胶、温柏籽胶、是海藻多糖类的角叉胶、褐藻酸、是树脂多糖类的阿拉伯橡胶、黄芪胶等;(2)作为动物性多糖类,例如鱼肠、鱼鳞等提取的胶原肽。

为进一步最大限度利用水分子通道,本发明优选透明质酸作为保湿因子;为进一步促进皮肤的新陈代谢、细胞水合以及皮肤的弹性,本发明选用的透明质酸包括高分子量的透明质酸、中分子量的透明质酸以及低分子量的透明质酸,三种不同种类的透明质酸协同作用,能促进胶原和神经酰胺的合成以及皮肤细胞的迁移与增殖,又可以在皮肤表面实现锁水、补水以及营养角质层的效果,还可以调节免疫细胞活性。
优选地,本发明中所述“高分子量的透明质酸”是指透明质酸钠;所述“中分子量的透明质酸”是指羟丙基三甲基氯化铵透明质酸;所述“低分子量的透明质酸”是指水解透明质酸。申请人发现水解透明质酸、羟丙基三甲基氯化铵透明质酸作为低分子和中分子类透明质酸与大分子类透明质酸,如透明质酸钠协同作用,既能满足低分子或中分子类透明质酸被细胞吸收,从而促进胶原和神经酰胺的合成,以及皮肤细胞的迁移与增殖;同时也具有在肌肤表面锁水、补水,营养角质层的功效。优选地,低分子量的透明质酸、超低分子量的透明质酸以及高分子量的透明质酸的重量比为(0.5~1.5):(0.5~1.5):(0.5~1.5)。
本发明对透明质酸钠、水解透明质酸、羟丙基三甲基氯化铵透明质酸的来源不做特别限定,一种实施方式中,透明质酸钠购自Q.P.Corporation,HYALURONSAN HA-LQH;水解透明质酸购自Q.P.Corporation,
羟丙基三甲基氯化铵透明质酸购自Q.P.Corporation,
在本发明体系中,采用了不同跨膜运输方式的协同作用,即本发明体系中还包括“囊泡转运”形式的跨膜运输方式,实现大分子和颗粒物质的膜泡运输,利用囊泡转运与水分子通道协同作用,实现物质的跨屏障运输。一般而言,大分子物质及颗粒性物质不能穿过细胞膜,则需要以膜泡转运的方式实现,即物质在进出细胞的转运过程中都是由膜包裹、形成囊泡、与膜融合或断裂来完成的,但是 在完成膜泡转运过程中实现物质的跨膜运输也是困难重重,细胞膜的脂肪酸外层尾部具有一定程度的疏水作用,脂溶性高的物质容易扩散以及被吸收,而脂溶性低或非脂溶性的物质则较难通过,更难与细胞膜融合,这样就会使得部分营养物质不能被皮肤细胞吸收,从而影响护肤产品在使用时的吸收效果。
本发明基于上述问题的考虑,优选地,在膜泡转运过程中,优先采用囊泡转运方式,在囊泡转运过程中,采用囊泡仿生成分将其承载的有效成分包裹形成纳米微脂囊小球;所述囊泡仿生成分包括但不限于卵磷脂,其成分包括有磷酸、胆碱、脂肪酸、甘油、糖脂、甘油三酸酯以及磷脂。申请人也发现在本发明体系中利用微脂囊小球可实现更好的膜融合,从而实现营养物质的有效包裹与吸收,可能是在本体系中微脂囊小球可以将水溶性的大分子包裹于其间隙中,而脂溶性或者同时具有水溶性与脂溶性的物质结合在其脂质双分子中或亲脂基团中,从而在其与细胞膜融合过程中可以将其承载的有效成分输送至细胞内部,从而实现营养物质的高效吸收。
一般而言,纳米微脂囊小球可以承载用于皮肤修护的各种营养大分子或小分子物质,本发明基于对皮肤抗衰老以及皮肤修护效果的考虑,优选地,纳米微脂囊小球的承载的有效成分包括功能因子以及水分子;进一步,功能因子包括细胞活性促进因子、组织修复因子、低氧诱导调节因子、抗氧化因子中的任一种或多种组合。
在具体工作过程中,囊泡转运可以与水通道识别形式的跨膜运输协同作用,首先在保湿因子作用下,更高效打开水分子通道实现补水,其与纳米微脂囊小球协同作用,实现功能因子的跨屏障高效运输,避免对皮肤屏障的胁迫和损害,又可以在一定程度上促进和修复皮肤的屏障功能。
人体皮肤细胞衰老时,也会伴随着皮肤细胞变差、细胞内氧化压力增大而导致的氧化损伤,同时也会出现细胞呼吸受阻、细胞内氧气含量降低,而氧气感知几乎存在于所有细胞中,表皮的角质形成细胞能在低氧状态下对外界环境做出反应,从而影响促红细胞生成素的产生,调节红细胞的产生和血液的携氧能力。在本发明研究过程中,申请人发现在诱导激活过程中,低氧诱导调节因子通过低氧诱导类物质间接激活细胞活性,这样可以避免出现细胞内活性氧和自由基含量上升,也避免了DNA结构损伤和蛋白酶活性的降低。
进一步地,为实现对损伤和衰老细胞的精准激活,调控皮肤的氧化还原环境,减少皮肤细胞活性的下降以及胶原蛋白的合成受阻等问题。在本发明研究过程中,优选地,采用低氧诱导调节因子在低氧诱导信号下,介导微脂囊小球与靶向细胞膜融合,并释放功能因子以及水分子。在实际工作中,低氧诱导调节因子可以激活损伤和衰老的细胞,从而保证有效的靶向修复,在低氧诱导调节因子作用下,可以与纳米微脂囊小球协同作用,实现其承载的功能因子的靶向精准释放,这是因为在损伤、衰老的皮肤中,细胞呼吸不畅,损伤和衰老的皮肤细胞活力不足,处于低氧状态,可以触发低氧信号,诱导生成低氧诱导因子-1(HIF-1);而这一低氧诱导信号可以被低氧诱导调节因子迅速捕捉,进而调节HIF-1并参与皮肤细胞的呼吸链过程,实现囊泡的靶向送达与精准释放,再利用其包裹的功能因子,从而提高营养物质的高效利用;实现对损伤、衰老细胞的快速、精准、高效修复;所述低氧诱导调节因子为能感知低氧信号,调节细胞呼吸的物质;例如植物提取物、动物提取物、微生物提取物、脂溶性醌类中的一种或几种组合;作为植物提取物,例如丹参提取物、菊花提取物、泽兰提取物、天麻提取物、人参提取物、黄岑提取物、三七提取物、绿茶提取物、银杏叶提取物、南蛇藤提取物;作为动物提取物,例如蝎毒多肽提取物等;作为微生物提取物,例如酵母提取物等;优选为泛醌,其为一种脂溶性醌类,带有由不同数目(6~10)异戊二烯单位组成的侧链。
基于对膜融合高效性的考虑,本发明采用细胞活性促进因子与微脂囊小球协同作用,促进高活效融合,其能有效促进纤维芽细胞的活性,激活真皮层胶原蛋白生成,同时也参与了红细胞的组成,与铁协同作用,促进组织和黏膜的形成,从而实现与目标细胞膜的高效融合。细胞活性促进因子可以为本领域熟知的组分,例如视黄醇及其衍生物,视黄醇是一种可溶于脂肪的脂溶性维生素,耐高温,而视黄醇衍生物经体内活性代谢产物视黄酸介导两大类视黄酸受体RARs(α、β、γ)和RXRs(α、β、γ)调控基因的表达,形成皮肤的结构蛋白、酶以及细胞外基质等,视黄醇衍生物例如视黄醇棕榈酸酯。
在低氧诱导与囊泡转运相互配合,完成微脂囊小球与目标细胞的融合,实现营养物质的释放之后,需要进行损伤修复的过程;在研究中发现,在损伤修复的过程中,氧化应激通路的信号分子活化蛋白激酶和转录因子进行细胞内的信号传 导,进一步地,纳米微脂囊小球的承载物质对细胞实现靶向修复;为进一步实现皮肤的修复效果,优选地,氧化应激通路的信号分子包括组织修复因子;组织修复因子可以为本领域熟知的组分,选自生长因子、提取物、神经酰胺中的一种或几种组合;作为生长因子,例如表皮生长因子、成纤维细胞生长因子、血管内皮生长因子等;作为提取物包括植物提取物、动物提取物、微生物提取物,例如雪藻提取物、凤尾草提取物、木豆叶提取物、大翅蓟属提取物、乳香提取物、银杏叶提取物、木豆叶提取物、艾叶提取物、动物水解蛋白、蚕丝提取物、蜂胶提取物、鹿茸提取物、胎盘水解物、龟板提取物、美洲大蠊水提取物、酵母提取物等。

为进一步优化靶向皮肤修护与抗衰老的效果,申请人发现当采用抗氧化因子与本发明中的其他功能性因子协同作用,可以更好的实现皮肤修护与抗老的效果,申请人在研究中发现清除老化代谢产物以及提高抗氧化酶的活性可以有效延缓皮肤老化以及进行皮肤修护,生育酚能有效减少自由基产生,同时又可以与自由基或活性氧形成稳定态,避免自由基或活性氧对细胞的伤害,还有利于增强细胞端粒酶的活性,促进细胞的修复。抗氧化因子可以为本领域熟知的组分,具有抗氧化自由基作用的物质,选自植物提取物、动物提取物、微生物提取物、维生素、肽类物质、酚类物质、酶中的一种或几种组合;作为植物提取物,例如泽泻提取物、沙棘叶提取物、当归提取物、女贞子提取物、夏枯草提取物、黄岑根提取物、五味子提取物、甘草根提取物、丹参根提取物、木槿花提取物、金盏花提取物等;作为动物提取物,例如美洲大蠊提取物等;作为微生物提取物,例如乳酸菌提取物等;作为维生素类物质,例如维生素A、维生素C、维生素D、维生素E等;作为抗氧化因子为肽类物质,例如米糠肽、还原型谷胱甘肽、大豆肽、 乳蛋白肽等;作为酚类物质,例如生育酚、绿茶多酚、叔丁基对苯二酚等;进一步地,抗氧化因子优选为生育酚,即维生素E的水解产物。
