具体实施方式
下面将结合实施例对本发明的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。需要说明的是:本发明中,如果没有特别的说明,本文所提到的所有实施方式以及优选实施方法可以相互组合形成新的技术方案。本发明中,如果没有特别的说明,本文所提到的所有技术特征以及优选特征可以相互组合形成新的技术方案。本发明中,如果没有特别的说明,所涉及的各组分或其优选组分可以相互组合形成新的技术方案。本发明中,除非有其他说明,数值范围“a~b”表示a到b之间的任意实数组合的缩略表示,其中a和b都是实数。例如数值范围“1.5~2.5”表示本文中已经全部列出了“1.5~2.5”之间的全部实数,“1.5~2.5”只是这些数值组合的缩略表示。本发明所公开的“范围”以下限和上限的形式,可以分别为一个或多个下限,和一个或多个上限。本发明中,除非另有说明,各个反应或操作步骤可以顺序进行,也可以按照顺序进行。优选地,本文中的反应方法是顺序进行的。除非另有说明,本文中所用的专业与科学术语与本领域熟练人员所熟悉的意义相同。此外,任何与所记载内容相似或均等的方法或材料也可应用于本发明中。
在对本发明的实施例进行说明之前,先做如下说明介绍:基质金属蛋白酶(Matrix metalloproteinases, MMPs)是一类含有Zn2+、活性依赖Ca2+,能够降解细胞外基质(Extracelleular matrix, ECM)蛋白包括胶原蛋白和非胶原性大分子等成分的蛋白酶类,基质金属蛋白酶(MMPS)属于ECM水解酶类的一类高度保守的内源性蛋白酶,是martrixin家族的一支,在正常情况下,通常是在细胞内以未激活的酶原形式产生并经加工和修饰,将含有前肽区且无活性的前体蛋白分泌出胞外,参与生物体的生理生化过程,通常MMPS蛋白的一级结构包含一系列的结构元件,包括信号肽、前肽结构域、催化区域、铰链区结构域和类血红素结构域,目前为止已经发现30余种MMPS,其中在人类基因组中的MMPS有20种以上,一般来说MMPS都是通过分泌到细胞外或者是结合在细胞膜固定的催化位点上来发挥作用,根据MMPS的自身结构特点以及其特异性底物,可以将MMPS分为以下几个大类:胶原酶(MMPS-1,MMPS-8,MMPS-13);明胶酶(MMPS-2,MMPS-9);基质溶解酶(MMPS-3,MMPS-10,MMPS-11,MMPS-12);基质分解素(MMPS-7,MMPS-26)等。基质金属蛋白酶抑制剂(matrixmetalloproteinases inhibitors,MMPIS)分为体内天然的抑制剂以及人工合成的抑制剂,双麟酸( Bisphosphonates, BPs )是一类具有特征性 P-C-P 键的化合物,并具有抑制破骨细胞活性的功能,因此该类化合物作为抗骨质疏松药物已被广泛地应用于骨相关疾病以及溶骨性肿瘤转移的治疗中,例如,Boissier 发现了5种双脚酸化合物(Clodronate ,Ibandronate , Zoledronate 等)对 MMP-2 MMP-9 都有一定的抑制效果,它们的半数抑制浓度(IC 50)值都在 50-200 µM,且目前都己商品化。另外,双磷酸类化合物具有良好的水榕性、体内稳定性,而且经过多年的临床使用已被证明其具有毒性低和耐受性好等特点,因而可以利用双磷酸类化合物抑制MMP-13的活性,与其活化体形成稳定复合物,避免细胞外基质(如明胶)被降解。OAC1是一种能够激活Octamer-binding transcription factor 4(OCT4)的化合物,OCT4是一种转录因子,OCT4基因也被称为Oct3、POU5F1、Oct3或Oct4,是POU转录因子家族中的一员,人的OCT4基因位于6号染色体上(6p21.31),长度为16.40kb,具有多个转录起始位点,转录不同的mRNA亚型(Isoform),从而翻译成多种蛋白质,OCT4Isoform 1是转录的主要亚型之一,具有5个外显子,4个内含子,翻译的蛋白质含有一个保守的DNA结合结构域——POU结合域,它能与含八聚体基序(octamer motif)的DNA结合从而调控下游靶基因的转录,OCT4蛋白能够增强自体肤成纤维细胞(HDFs)的增殖能力。
具体实施例1:本发明提出一种用于阴道填充的填充物制备方法,其中胶原蛋白浓度固定为35mg/mL,BP1为5.0 µM,OAC1浓度为1.0 µM,利用胶原蛋白与金属蛋白酶抑制剂及OAC1联用,形成一种新的女性阴部注射用填充物,本发明的填充物中的金属蛋白酶抑制剂够防止填充部位的胶原蛋白被分解,同时联用OAC1能够激活体内的OCT4,进而能够促进自体成纤维细胞增殖,产生更多的胶原蛋白,使得私处能够恢复青春,且增强了自体的胶原蛋白产生能力,使得填充效果更为持久,本发明的阴道填充物制备方式如下:
首先是对胶原蛋白缓冲液的配制:A液(0.2M磷酸二氢钠水溶液): 取NaH2 PO4 ・H2O 27.6g,溶于蒸馏水中,稀释至1000mL,B液(0.2M磷酸氢二钠水溶液):取Na2 HPO4 ・7H2 O53.6g (或Na2 HPO4 ・12 H2 O 71.6g或Na2 HPO4 ・2 H2 O 35.6g ) 加蒸馏水溶解,加水至1000mL,然后,取A液19mL和B液81mL进行混合,即可得到pH=7.4的磷酸盐缓冲液,再向其中加入0 .3%(w/v)的盐酸利多卡因,即可得到胶原蛋白缓冲液;其次是对化合物母液的配制:使用称量天平称取0.237g OAC1化合物,溶于100mL蒸馏水中,配制得到浓度为10 mM的OAC1化合物母液,然后,使用称量天平称取3.32 gBP1化合物溶于1L蒸馏水中,配制得到浓度为10mM的BP1化合物母液;在总体积为50mL、工作浓度为35mg/mL胶原蛋白缓冲液中使用移液枪加入5.0微升的OAC1化合物母液;而后使用磁力搅拌器进行搅拌1 h,搅拌需在恒温箱中进行,温度设置为4℃;而后使用移液枪向其中加入BP1化合物母液25.0微升,而后使用磁力搅拌器进行搅拌1 h,搅拌需在恒温箱中进行,温度设置为4℃,最后进行分装30 mL注射器中,置于4℃环境下待用。
