Definitions

  • the present invention relates to a peptide compound, its use and compositions containing the same.
  • ChemR23 is the primary receptor for Chemerin.
  • Owman et al. identified a new cDNA sequence from the B lymphoblastic cDNA library.
  • the encoded protein is highly homologous to the G protein-coupled receptor (GPCRs) family and is named ChemR23 (CMKLR1 chemokine-like receptor 1).
  • ChemR23 is mainly expressed in leukocytes, adipocytes, endothelial cells, epithelial cells, osteoclasts, and vascular smooth muscle cells. ChemR23 has long been considered an orphan receptor because no ligand has been found. In 2003, when Wittamer et al.
  • Chemerin is a chemotactic membrane-bound protein secreted by fat cells.
  • the Chemerin gene is also known as tazarotene-induced gene 2 (TIG2) or retinoic acid receptor responder 2 (RARRES2), which is equivalent to the 1997 culture of psoriasis patients by Nag-pal. Found when skin cells.
  • TAG2 tazarotene-induced gene 2
  • RARRES2 retinoic acid receptor responder 2
  • the human chemerin gene is localized to the E2DL3 gene.
  • the Chemerin gene encodes a protein containing 163 amino acid residues. It is an inactive precursor secreted protein, prochemerin, with a relative molecular mass of 18KDa. This precursor protein has low biological activity and requires coagulation, fibrinolysis, and inflammation.
  • the C-terminus is further lysed outside the cell by plasmin, carboxypeptidase or serine protease to become an active protein.
  • Prochemerin is converted to a relative molecular mass of 16 kDa, a reactive chemerin, which is present in serum, plasma and body fluids after hydrolysis of a carboxy-terminal sequence by extracellular proteases.
  • the carboxy terminus of the Chermerin sequence is critical for its biological activity.
  • many prochemerin indented end-derived peptides were synthesized to observe the effect on ChemR23, and the shortest chemerin bioactive peptide was found to be chemerin-9.
  • the sequence of human chemerin-9 is chemerin149-157, YFPGQFAFS; the sequence of mouse-derived chemerin-9 is chemerin148-156, FLPGQFAFS.
  • Human chemerin-9 has similar biological activity as mouse-derived chemerin-9.
  • CMKLR1 has been found to be expressed in many immune cells, including inflammatory mediators (monocytes, macrophages, plasma cell expression/myeloid dendritic cells and natural killer cells), vascular endothelial cells, and neurons, glial cells. Spinal cord and retina, immature dendritic cells, myeloid dendritic cells, macrophages, and natural killer cells. It plays an important role in innate immunity, acquired immunity, inflammatory response, lipogenesis and lipid metabolism, and cell proliferation.
  • Chemerin and its receptor system play an important role in the pathology of viral pneumonia and are therefore likely to become antiviral and anti-inflammatory therapies.
  • Chemerin has a wide range of functions, such as promoting the chemotaxis of dendritic cells, macrophages and NK cells to the site of inflammation, inhibiting the synthesis of proinflammatory mediators TNF ⁇ and IL-6, increasing the production of adiponectin, and promoting the differentiation of adipocytes. Mature, improve insulin sensitivity to insulin and glucose uptake, regulate lipolysis, increase TNF- ⁇ synthesis, increase NF- ⁇ activity, increase VEGF and MMPs synthesis and regulate neovascularization and angiogenesis, etc. . Therefore, Chemerin plays an important role in immune response, inflammatory response, lipogenesis and lipid metabolism (involving obesity, fatty liver, diabetes and metabolic syndrome), and has a good application prospect.
  • Chemerin is also used in asthma, a chronic inflammatory disease of the respiratory tract. Failure to take any anti-inflammatory measures can result in bronchial obstruction or contracture, and may even be life-threatening due to difficulty breathing. Asthma is listed by the World Health Organization as one of the four major chronic diseases in the disease. It is also the second most dead and disabling disease in the world after cancer. In some developed countries in the West, the incidence of asthma is as high as 20%, and some even as high as 40%. The prevalence of asthma in China is growing very fast.
  • peptide drugs Compared with most organic small molecule drugs, peptide drugs have the characteristics of high biological activity, small dosage, low toxic side effects and amino acid metabolism. Compared with macromolecular proteins or antibody drugs, it has a smaller molecular weight, similar protein activity, more significant functions, chemical synthesis, high product purity, controllable quality, and small peptides with almost no immunogenicity. Drug development The prospects are very good. The research and development of peptide drugs has become an emerging international high-tech field with great market potential.

一种肽类化合物、其应用及含其的组合物

技术领域
本发明涉及一种肽类化合物、其应用及含其的组合物。
背景技术
ChemR23是Chemerin的主要受体。1996年Owman等从B淋巴母细胞cDNA文库中鉴定出一个新的cDNA序列，其编码蛋白质与G蛋白耦联受体(GPCRs)家族高度同源，命名为ChemR23(CMKLRl chemokine-like receptor 1)。ChemR23主要表达于白细胞、脂肪细胞、内皮细胞、上皮细胞、破骨细胞以及血管平滑肌细胞。因未发现其配体，ChemR23曾一直被认为是个孤儿受体。2003年Wittamer等在寻找G蛋白偶联受体chemR23(CMKLR1)的配体时，发现在炎症体液里TIGZ编码的蛋白是其配体，为了便于与chemR23对应，命名为Chemerin。Chemerin在人体的多种组织广泛表达，在脂肪组织、肾上腺、肝脏、肺、胰腺、胎盘、卵巢、皮肤等都有表达，其中主要表达于白色脂肪组织、肝脏和肺。脂肪细胞因子Chemerin是一种由脂肪细胞分泌的具有趋化作用的膜结合蛋白。
Chemerin基因也称他佐罗汀诱导基因2(tazarotene-induced gene2，TIG2)或视黄酸受体反应组件2(retinoicacid receptor responder 2，RARRES2)，由Nag-pal等于1997年培养银屑病患者的皮肤细胞时发现。
人类chemerin基因定位于E2DL3基因。Chemerin基因编码一个含163个氨基酸残基的蛋白质.属无活性前体分泌蛋白，即prochemerin，相对分子质量为18KDa，这种前体蛋白的生物活性很低，需要在凝血、纤溶、炎症级联反应过程中在细胞外进一步经过纤溶酶、羧肽酶或丝氨酸蛋白酶对C末端进行裂解才能成为有活性的蛋白。prochemerin经胞外蛋白酶水解羧基端的一段序列后转变为相对分子质量为16KDa,有活性的chemerin，出现在血清、血浆和体液中。目前认为，内源性活化的chemerin之所以具有如此广泛而多样的生理学效应可能与其胞外存在多种蛋白酶对prochemerin产生不同的酶解方式相关。Chemerin在羧基末端有多个蛋白酶切割位点,研究者也观察到多个酶都能 将chemerin裂解成有活性的蛋白。在某些情况下需要多重裂解以激活chemerin。
Chermerin序列的羧基末端对其保持生物活性至关重要。为研究chemerin的活性肽段，近年来人工合成许多prochemerin缩进末端来源的肽段来观察其对ChemR23的作用，发现最短的chemerin生物活性肽段为chemerin-9。人源chemerin-9的序列为chemerin149-157，YFPGQFAFS；小鼠源chemerin-9的序列为chemerin148-156，FLPGQFAFS。人源chemerin-9和小鼠源chemerin-9有相似的生物活性。
Chemerin最初是以炎症因子被发现的，研究发现chemerin通过其受体CMKLR1促进未成熟的树突细胞和巨噬细胞趋化。目前发现CMKLR1在很多免疫细胞都有表达，包括炎症介质(单核细胞、巨噬细胞、浆细胞表达/髓样树突状细胞和自然杀伤细胞)、血管内皮细胞以及神经元、神经胶质细胞、脊髓和视网膜、未成熟的树突状细胞、髓样树突细胞、巨噬细胞和自然杀伤细胞等。它在先天性免疫，获得性免疫、炎症反应、脂肪生成与脂质代谢、细胞增殖等方面都发挥着重要作用。
Chemerin及其受体系统在病毒性肺炎的病理学中扮演重要角色，因此有可能成为抗病毒和抗炎的疗法。
Chemerin功能广泛，如促进树突细胞、巨噬细胞和NK细胞到炎症位点的趋化作用、抑制促炎介质TNFα和IL-6的合成、增加脂联素的产生、促进脂肪细胞的分化与成熟、提高脂肪细胞对胰岛素的敏感性和葡萄糖的摄取、调节脂解作用、增加TNF-β的合成、提高NF-κβ的活性，增加VEGF和MMPs的合成并调节新生血管生成和血管再生等等。因此，Chemerin在免疫应答、炎症反应、脂肪生成与脂质代谢(涉及肥胖、脂肪肝、糖尿病和代谢综合征)等方面发挥了重要作用，应用前景较好。
Chemerin还可用于哮喘，哮喘是一种呼吸道的慢性炎症疾病。如果没有采取任何抗炎的措施，将会导致支气管阻塞或挛缩，甚至可能因呼吸困难而危及生命。哮喘被世界卫生组织列为疾病中四大顽症之一，它也成为仅次于癌症的世界第二大致死和致残疾病。在西方一些发达国家，哮喘发病率高达20％，有些甚至高达40％。而我国的哮喘患病率增长速度非常快。
体内发现的多种天然趋化素及其酶切产物，都是蛋白质，具有分子量相对较大、制备困难、存在抗原性、稳定性差等缺点，很难大批量生产和开展大动物及人体的实验研究及药物开发。因此，新型的多肽趋化素因子受体1激动剂的研发，预示着治疗一系列炎症和癌症(肿瘤免疫)的新颖方法的开展。
与多数有机小分子药物相比，多肽类药物具有生物活性高、用药剂量小、毒副作用低和代谢终产物为氨基酸等突出特点。与大分子的蛋白质或抗体药相比分子量较小，同 样具有类似蛋白质的活性，功能更显着，可化学合成，产品纯度高，质量可控，较小的肽几乎没有免疫原性，药物开发前景非常好。多肽药物的研究与开发已经成为国际上新兴的生物高科技领域，具有极大的市场潜力。

Figure PCTCN2018093088-appb-000096
若具体序列的右端以氨基酸(XX10)结尾，未明确-P是哪一基团，即表示默认P为-OH。
在本文中使用常规的用于表示氨基酸的单字母或三字母代码来定义本发明所述的肽分子。术语“氨基酸”包括水溶性的、具有与α-碳原子连接的羧基(-COOH)和氨基(-NH 2)基团的有机化合物。氨基酸可以用通式R-CH(NH 2)COOH表示；R基团为氢或有机基团，并且决定了任意具体氨基酸的性质。当R不是氢时，α-碳原子周围的四个不同基团的四面体排列使氨基酸具有光学活性。两种镜像形式被称为L-异构体和D-异构体。通常，仅有L-氨基酸是蛋白质(如真核蛋白质)的组成成分。
除非另作说明，本发明的肽分子包含L-氨基酸。当D-氨基酸存在于本发明的肽分子时，用带有前缀“(D)”的常规单字母氨基酸代码表示。
如所述，本发明的分子可以包含在特定位置具有“任意D-氨基酸”的肽序列或由在特定位置具有“任意D-氨基酸”的肽序列组成。所述“任意D-氨基酸”包括在序列中在特定位置的任意天然或非天然(例如化学修饰的)D-氨基酸。天然D-氨基酸的实例如下：D-丙氨酸；D-天冬氨酸；D-半胱氨酸；D-谷氨酸；D-苯丙氨酸；D-甘氨酸；D-组氨酸；D-异亮氨酸；D-赖氨酸；D-亮氨酸；D-蛋氨酸；D-天冬酰胺；D-脯氨酸；D-谷氨酰胺；D-精氨酸；D-丝氨酸；D-苏氨酸；D-缬氨酸；D-色氨酸；D-酪氨酸。非天然D-氨基酸的实例如下：萘基丙氨酸；D-吡啶基丙氨酸；D-叔丁基丝氨酸；D-鸟氨酸；D-ε氨基赖氨酸；D-高精氨酸；D-α甲基亮氨酸以及用卤素取代(如F)这些和其它非天然氨基酸中的质子。
通过形成肽键，氨基酸结合形成短链(肽)或较长的链(多肽)。已知蛋白质和/或肽由不同流动相比例的大约20种常见氨基酸组成，其序列决定了蛋白质和/或肽的形状、性质和生物学作用。这种肽或多肽链中的氨基酸残基通常用它们在链上的排列位置来表示，第一位(即位点1)指定为链N-末端的氨基酸。

术语“前药”是指包含生物反应官能团的化合物的衍生物，使得在生物条件下(体外或体内)，生物反应官能团可从化合物上裂解或以其他方式发生反应以提供所述化合物。通常，前药无活性，或者至少比化合物本身活性低，使得直到将所述化合物从生物反应官能团上裂解后才能发挥其活性。生物反应官能团可在生物条件下水解或氧化以提供所述化合物。例如，前药可包含可生物水解的基团，可生物水解的基团实例包括但不限于可生物水解的磷酸盐、可生物水解的酯、可生物水解的酰胺、可生物水解的碳酸酯、可生物水解的氨基甲酸酯和可生物水解的酰脲。有关前药的综述参见，例如，J.Rautio et al.,Nature Reviews Drug Discovery(2008)7,255-270 and Prodrugs:Challenges和Rewards(V.Stella et al.ed.,Springer,2007).
本发明的积极进步效果在于：本发明的肽类化合物的稳定性较佳且活性较佳。
具体实施方式
下面通过实施例对本发明进行详细描述，但并不意味着对本发明任何不利限制。本文已经详细地描述了本发明，其中也公开了其具体实施例方式，对本领域的技术人员而言，在不脱离本发明精神和范围的情况下针对本发明具体实施方式进行各种变化和改进将是显而易见的。
可以通过Lu et al(1981)J.Org.Chem.46，3433和其中的参考文献中公开的Fmoc-聚酰胺式固相肽合成法来合成本发明分子的肽序列。用9-芴基甲氧羰基(Fmoc)基团提供临时的N-氨基保护。使用含20％哌啶的N，N-二甲基甲酰胺进行该高度碱不稳定的保护基团的重复去除。可以将侧链官能团保护成其丁基醚(对于丝氨酸、苏氨酸和酪氨酸的情况)、丁基酯(对于谷氨酸和天冬氨酸的情况)、丁基氧羧基衍生物(对于赖氨酸和组氨酸的情况)、三苯甲基衍生物(对于半胱氨酸的情况)和4-甲氧基-2，3，6-三甲基苯磺酰衍生物(对于精氨酸的情况)。当C-末端残基为谷氨酰胺或天冬酰胺时，使用4，4′-二甲氧基二苯甲基基团保护侧链氨基官能团。固相载体基于由二甲基丙烯酰胺(主链单体)、双丙烯酰乙二胺(交联剂)和丙烯酰肌氨酸甲酯(功能化试剂)三种单体组成的聚二甲基-丙烯酰胺聚合物。所使用的肽-树脂可断裂连接剂为酸不稳定的4-羟甲基-苯氧基乙酸衍生物。除了天冬酰胺 和谷氨酰胺之外，全部氨基酸衍生物均作为它们预制的对称酐衍生物加入，而使用反向N，N-二环己基碳二亚胺/1-羟基苯并三唑介导的偶联方法加入天冬酰胺和谷氨酰胺。使用茚三酮、三硝基苯磺酸或吲哚醌(isotin)检测方法来监测所有的偶联和去保护反应。合成完成时，从树脂载体切下肽，同时用含有50％清除剂混合物的95％三氟乙酸处理去除侧链的保护基团。常用的清除剂为乙二硫醇、苯酚、苯甲醚和水，准确的选择取决于所合成的肽的氨基酸组成。通过真空蒸发去除三氟乙酸，接着通过用乙醚研磨而提供粗肽。通过简单的萃取步骤来去除存在的任何清除剂，其中通过冷冻干燥水相提供不含清除剂的粗肽。用于肽合成的试剂通常可购自Calbiochem-Novabiochem(UK)Ltd，Nottingham NG7 2QJ，UK。纯化可以通过例如体积排阻色谱法、离子交换色谱法和(主要地)反相高效液相色谱法等技术中的任意一种或组合来实现。肽的分析可以使用薄层色谱法、反相高效液相色谱法、酸水解后的氨基酸分析以及快速原子轰击(FAB)质谱分析来进行。
还可以使用化学和生物化学领域技术人员所熟知的液相法来合成本发明分子的肽序列。
