顶体蛋白的 ^途及制备方法
技术领域
本发明涉及顶体蛋白的用途及制备方法。
背景技术
众所周知, 肿瘤是当前严重影响人类健康, 威胁人类生命的主要疾病之 一, 已成为人类致死的首要原因。 据统计, 中国每年有 160万人死于癌症, 世界上每年有 740万人死于癌症。 虽然目前治疗癌症的药物和治疗手段不断 在更新, 但癌症发病率和死亡率仍在不断增加, 预计 2030年全世界将有超过 1200万人死于癌症。
癌是机体正常细胞快速产生异常细胞, 并发生转移, 扩散到其他器官, 同时异常细胞增生过程中, 吸收营养, 破坏人体免疫力和抵抗力, 导致机体 功能紊乱, 失去平衡, 最终导致人死亡。
目前国际上对癌症病因及发病机理尚未完全认识, 对于癌症的治疗, 常 规疗法无外乎手术治疗、 药物化疗、 放射性治疗和以毒攻毒等。 他们对癌症 的治疗虽能起一定作用, 使部分患者病情暂时好转, 但容易再次复发和转移, 同时正常的组织细胞及机体免疫力不可避免地在治疗过程中受损, 给患者带 来难以忍受的痛苦和食欲不振、 呕吐、 发烧、 大小便失禁、 抑郁、 失眠等症 状, 患者生活质量严重降低。 经过传统的化学治疗后, 患者会头发脱落、 骨 瘦如柴, 不能饮食吞咽。 致使许多患者未死于癌症而死于放化疗和手术。 当 这些弊端日益显现时, 一些人进而转向基因和免疫学等途径, 但迄今未取得 实质性的进展。
专利 CN200710017785.3已描述了动物精液药材在治疗肿瘤、抑郁症等多 种疾病中的药物应用, 专利申请 201010219062.3描述了动物精液冻干粉的制 备方法。 但精液的主要成分为水, 约占 90%以上, 在有形成分中, 除成熟精 子外, 尚有 1%的其他细胞, 如未成熟的精原细胞、 精母细胞以及生殖管道脱 落的上皮细胞和少量白细胞, 除细胞外, 精液内还含有脂肪及蛋白质颗粒、 色素颗粒、 前列腺液的磷脂小体, 无机盐、 酶类、 乳酸及果糖等; 现有技术 并未确定动物精液中何种物质起到治疗肿瘤、 抑郁症等疾病的作用, 直接应 用动物精液制备的药物纯度也较低, 因此效用较差, 患者的服用剂量大。 发明内容
本发明提供的顶体蛋白的用途及提取方法, 主要解决了现有应用动物精 液制备治疗肿瘤、 抑郁症等多种疾病中的药物纯度低、 需服用的剂量大及精 液中的非特异性蛋白、 脂肪和糖类化合物等杂质对治疗效果的干扰的问题; 本发明提供的顶体蛋白的用途及提取方法, 极大地提高了药物的纯度和药效, 突破了现有技术的局限性。
本发明的具体技术解决方案如下:
顶体蛋白可以用于抑制癌细胞的扩散,尤其是用于抑制 MCF-7、 Bel7402、 BGC823、 A2780、 A549或 HCT-8细胞的扩散。
顶体蛋白在制备治疗癌症、 抑郁症的药物中的应用。 癌症包括妇科肿瘤、 消化道肿瘤、 肺癌、 肝癌、 白血病和恶性淋巴瘤; 妇科肿瘤包括子宫肌瘤、 卵巢癌、 乳房瘤、 乳腺癌和宫颈癌; 消化道肿瘤包括食道癌、 胃癌、 大肠癌。
顶体蛋白可以用于制备胶囊、 颗粒、 片剂、 滴丸、 中西药复方制剂、 口 服液或注射液。

3]将经歩骤 3处理所得的蛋白粗提物进行柱层析,用醋酸缓冲溶液平衡洗 脱, 处理完成后收集洗脱液; 一般是用葡聚糖凝胶柱、 羟丙基葡聚糖凝胶柱、 丙烯酰胺凝胶柱或琼脂糖凝胶柱进行柱层析, 其中优选的为葡聚糖凝胶柱和 羟丙基葡聚糖凝胶柱; 醋酸缓冲溶液是 pH=2, O.lmol/L的醋酸缓冲溶液, 醋 酸缓冲溶液平衡洗脱的流速为 0.5ml/min,处理完成后收集在 680nm处有最大 吸收的洗脱液;
4]将洗脱液以 2000r/min〜8000r/min离心 5〜10min, 弃去上清液, 所得沉 淀洗涤后以 2000r/min〜8000r/min继续离心 1〜3次, 每次离心 5〜10min, 收集 沉淀, 即得到顶体蛋白。
本发明的优点在于:
本发明通过大量的实验研究, 突破现有技术应用上的局限性, 获取了顶 体蛋白在治疗子宫肌瘤、 乳房瘤、 胃癌、 肺癌、 肝癌、 白血病、 大肠癌、 卵 巢癌、 乳腺癌、 宫颈癌、 恶性淋巴瘤及治疗抑郁症等疾病的药物中的应用; 极大地提高了该类药物的纯度, 并降低了患者的服用剂量和动物精液冻干粉 中含有的其他物质可能造成的影响。
经检测, 动物精液中顶体蛋白含量约为 0.1%〜0.4%。 经提纯后, 顶体蛋 白含量大于 90%, 与动物精液或其冻干粉相比, 药物浓度得到了很大提高, 并且剔除了精液中的非特异性蛋白、 脂肪和糖类化合物, 从药效上提高抗肿 瘤活性, 并且降低了服用剂量, 更方便临床应用。
可制成可制成胶囊、 颗粒、 片剂、 滴丸、 口服液、 注射液等各种制剂应 用于临床, 优选为胶囊。 本品也可与其他药物制成中西药复方制剂应用。 具体实施方式 顶体蛋白是卵子与精子受精过程中所不可缺少的生物活性物质。 其化学 成分为丝氨酸蛋白溶解类物质, 可溶解卵膜。 当卵子和精子都成功地被输送 到受精部位时, 精子的头部一旦接触到卵子表面时, 位于其头部顶端的细胞 器之一的顶体就随之发生顶体反应, 由顶体部分伸长为顶体丝, 并分泌出多 种酶蛋白, 即顶体蛋白, 顶体蛋白溶解卵膜, 使精子头部穿透卵的放射冠和 透明带, 而进入卵子, 完成受精过程。 因此, 顶体蛋白活性临床上常成为精 液分析评价精子功能的定量指标。
顶体蛋白可通过对冷冻保存的精子使用去垢剂,声处理和低 pH等方法提 取, 并用凝胶过滤, 离子交换层析, 等电聚集, 亲和层析和电泳等生化技术, 可获得纯顶体蛋白。 但不同哺乳动物和采用的不同分离方法所得到的顶体蛋 白分子量差异较大, 如人顶体素为 30KD〜70KD, 而猪的约为 41KD〜56KD。
顶体素分子是由酶原区、 催化区、 尾区三部分组成, 其中酶原区、 催化 区氨基酸序列无种属差异, 尾区有种属差异。
经药效学实验证实, 顶体蛋白对 MCF-7、 Bel7402、 BGC823、 A2780、 A549及 HCT-8六种人癌细胞株有抑制作用,对小鼠 S180肿瘤抑制作用明显, 与动物精液冻干粉相比, 抑瘤作用明显, 同时药用剂量也显著降低。 同时本 品与化疗药物联用能明显增加对化疗药物治疗肿瘤的治疗作用, 提示本品有 应用于治疗肿瘤的广泛前景。 人体临床应用情况表明, 本品治疗癌症有实质 性的临床应用效果; 将动物精液提纯得到顶体蛋白属于重大创新和发明, 有 利于降低患者服药剂量, 为上述疾病的治疗提供了一种新的药用物质。
顶体蛋白可制成胶囊、 颗粒、 片剂、 滴丸、 口服液、 注射液等各种制剂 应用于临床, 优选为胶囊, 顶体蛋白具有较好的稳定性, 优选的胶囊在遮光、 密封条件下可保存 24个月, 可稳定有效的应用于临床。 本品也可与其他药物 制成中西药复方制剂应用。
