8-乙烯亚胺-小白菊内酯盐酸盐及其制备方法与应用 技术领域
本发明涉及药物化学领域,具体涉及一种8-乙烯亚胺-小白菊内酯盐酸盐组合物制备方法和在改善皮肤的护肤品中的应用。
背景技术
8-乙烯亚胺-小白菊内酯盐酸盐是含香内酯的衍生物,是由天然提取物小白菊内酯为原料制取而来,在本文中将其简称为Tanaclear。小白菊内酯是从草本类植物艾菊中纯化出的一种倍半萜烯内酯化合物,具有抗炎、抗肿瘤、抗血小板聚集等特征。通过抑制肿瘤坏死因子(TNF-α)、白介素-1(interleukin-1,IL-1)、IL-12及环氧化酶-2(COX-2)等的表达而具有抗炎作用;通过抑制NF-кB的活化以及磷酸化来促进癌细胞的凋亡,同时抑制IL-8、血管内皮生长因子(vascular endothelial groth factor,VEGF)的产生,起到抗肿瘤的作用;关于Tanaclear目前在临床上主要是用于治疗皮肤感染、偏头痛、风湿病以及治疗肿瘤等疾病。
痤疮等皮肤问题可由炎症引起,通过抑制炎症并改善皮肤状态可有效改善痤疮、皮肤损伤等问题。到目前为止,Tanaclear在护肤品中的应用能够尚无明确报道。
发明内容
本发明的一个目的是提供一种应用价值高的8-乙烯亚胺-小白菊内酯盐酸盐组合物,发明的另一个目的是提供一种制备本发明的8-乙烯亚胺-小白菊内酯盐酸盐组合物的方法,同时提供一种8-乙烯亚胺-小白菊内酯盐酸盐组合物在在抗炎修复、促进表皮成纤维细胞增殖、改善皮层供血的护肤品中的应用。
为实现上述目的,本发明采用如下技术方案,本发明的8-乙烯亚胺-小白菊内酯盐酸盐组合物,其分子结构式为:
Figure PCTCN2020096654-appb-000001
其中,n是2-10000;由于其聚乙烯亚胺作为一种聚合物,本身没有确定分子量,只是一个范围,而已知聚乙烯亚胺的分子量范围就是0-500000,而根据实验明确可知,目前从两个乙二胺聚合到分子量50万的聚乙烯亚胺,基本是2到1万个乙二胺聚合,故结构式中的n是2-10000。
上述8-乙烯亚胺-小白菊内酯盐酸盐的制备方法,包括以下步骤:
1)以聚乙烯亚胺和小白菊内酯为起始原料,以二氯甲烷作为溶剂,经加成反应,得到小白菊内酯胺基加成产物;
2)将步骤1)得到的小白菊内酯胺基加成产物与氯化氢气体或稀盐酸溶液反应成盐,得到目标产物8-乙烯亚胺-小白菊内酯盐酸盐。
进一步改进地,步骤1)中,加成反应结束后,用水将未反应完的聚乙烯亚胺清洗干净。
进一步改进地,步骤2)中,具体为:反应液需边搅拌边通入氯化氢气体,通入氯化氢气体的过程中,逐渐有白色固体析出,通气至不再有白色固体析出,然后再继续搅拌1小时,保证全部小白菊内酯胺基加成产物与氯化氢气体反应得到目标产物8-乙烯亚胺-小白菊内酯盐酸盐。
进一步改进地,步骤2)中,具体为:边搅拌边加入稀盐酸溶液,搅拌期间要测量水溶液的pH值,当水溶液pH值为4-5时,停止滴加盐酸水溶液;保证全部小白菊内酯胺基加成产物与稀盐酸溶液反应得到目标产物8-乙烯亚胺-小白菊内酯盐酸盐。
本发明还提供了上述组合物即8-乙烯亚胺-小白菊内酯盐酸盐在改善皮肤的护肤品中的应用。
在上述应用中,所述改善皮肤的护肤品包含所述8-乙烯亚胺-小白菊内酯盐酸盐、所述8-乙烯亚胺-小白菊内酯盐酸盐在护肤品中可接受的盐、酯或它们的组合以及辅料。
在上述应用中,所述改善皮肤的护肤品包括剂型,且为临床上可接受的任一剂型。
优选地,8-乙烯亚胺-小白菊内酯盐酸盐在抗炎修复、促进表皮层纤维细胞增殖、改善皮层供血的护肤品中的应用。
所述8-乙烯亚胺-小白菊内酯盐酸盐为抗炎修复、促进表皮层纤维细胞增殖、改善皮层供血等护肤的唯一活性成分;或8-乙烯亚胺-小白菊内酯盐酸盐与其他物质一起制备所述抗炎修复、促进表皮成纤维细胞增殖、改善皮层供血等护肤的药物。
本发明与现有技术相比,因为炎症因子TNF-α和NF-κB所在的信号通路是一个正反馈调节过程,本发明的8-乙烯亚胺-小白菊内酯盐酸盐可以显著抑制皮肤表皮细胞分泌TNF-α因子,进而可以抑制细胞内NF-κB因子的表达,从而达到消炎的目的;另外本发明也可以促进表皮成纤维细胞增殖、改善皮层供血应用中的活性。

(2)结果如图4所示,
其中:对照组六名志愿者脸部痘痘在7天内无改善;Tanaclear组祛痘率为83.33%,痘印全部祛除;阳性药克林霉素磷酸酯凝胶组祛痘率为50%,痘印祛 除率为16.67%。改善效果展示如下:
(3)结论:
阳性药克林霉素磷酸酯凝胶对化脓性且中间有显著白点的痘痘改善效果明显,而对红肿性痘痘改善效果有限,表明该阳性药对痘痘的治疗具有选择性,而在痘印祛除方面克林霉素磷酸酯凝胶药效有限,不能很好的祛除痘印。
Tanaclear在两种情况的痘痘的点痘与祛痘印改善中均表现出优异的效果,其对痘痘的治疗效果优于阳性药组。
