Abstract
本发明提供了一种多肽活性化合物,特别是羟脯氨酸的三肽化合物及其制备方法,以及所述化合物的医药用途,特别是皮肤美容,包括治疗皱纹的应用。本发明涉及的化合物具有很好的抗皱纹作用,其活性高于市场现在使用的同类产品,并且通过本发明的制备方式制备,得到产品的产率高,非常适用于市场普及推广。所述多肽活性化合物结构式如下:
Description
技术领域
本发明属于医药领域,特别涉及一种多肽化合物和其制备方法,以及和其医药应用,特别是皮肤美容的应用。
背景技术
皱纹的产生与年龄、表情肌和重力等密切相关。当表情肌收缩时,皮肤会收缩而出现皱纹。正常的、年轻的皮肤具有一定的弹性和张力,当表情肌松弛后,皮肤会很快复原,使皱纹消失。人进入中年后,人体各项机能活跃度逐渐下降,皮肤作为人体最大的器官也开始明显老化,皮肤变薄、变硬、干燥、张力降低。真皮弹力纤维、断裂,使皮肤的张力和弹性降低,这样,当表情肌松弛后,皮肤不能很快复原,久之则使皱纹“凝固”下来,表情肌不收缩皱纹依然存在。随年龄增大,皮肤和皮下组织更加松弛,加上面部支持组织的萎缩或缺失,以及肌肉的松软,皮肤将会在重力的作用下发生滑坠,形成更深的皱纹。
目前通常采用侵入式的方法祛除皱纹,如采用注射肉毒杆菌毒素(Botox)使面部表情肌麻痹松弛而达到迅速祛皱的功效。Botox作用于胆碱能运动神经末梢,神经肌肉接头即突触处,抑制突触前膜神经介质—乙酰胆碱的释放,使肌肉纤维不能收缩,肌张力减低,因而肌肉麻痹。这种肌松弛时间是有限的,只能维持3~6个月。这种方式也伴随着很大的风险,如感染、疼痛、注射不当引起面瘫等。
在此基础上,彭特法姆股份公司申请的专利CN101061134A公开了一种Dipeptidediaminobutyroyl benzylamide diacetate,其具有良好的对抗皱纹的作用。其不具有Botox的风险,局部外用即可取得较好效果。与Botox不同,Dipeptide diaminobutyroylbenzylamide diacetate作用于突触后膜,是肌肉烟碱乙酰胆碱受体(nmAChR)可逆转的拮抗剂。其与nmAChR的ε亚单位结合从而阻滞神经递质乙酰胆碱与受体的结合,使兴奋传递减弱,肌肉受到刺激减少而松弛。
随着市场的增长,人们对祛皱抗衰产品的需求也在逐渐增长,虽然Dipeptidediaminobutyroyl benzylamide diacetate具有较好的祛皱效果,但并不能满足市场的需求,加之其昂贵的价格,也限制了其在市场的推广应用。
发明内容
本发明的目的是寻找祛皱效果更好,成本低,适合市场推广普及的化合物。通过大量实验在Dipeptide diaminobutyroyl benzylamide diacetate的基础上进行结构改造而得到本发明优选化合物,偶然发现在Dipeptide diaminobutyroyl benzylamidediacetate杂环上引进一个羟基,也即将其脯氨酸改成羟脯氨酸,得到了一系列具有优越活性的羟脯氨酸的三肽化合物。
根据药效试验测试,在建立的人肌细胞和来自小鼠胚胎的脊髓的神经元的共培养模型中分别加入本发明的化合物和Dipeptide diaminobutyroyl benzylamidediacetate,观察培养模型的肌肉收缩频率(详见表5),发现本发明的化合物NO.3等化合物与Dipeptide diaminobutyroyl benzylamide diacetate相比(P<0.05),有显著性差异,证明了本发明的化合物NO.3等化合物具有更强的活性,更优秀的祛皱效果。
发明人推测本发明化合物具有更好的祛皱效果是由于结构中引进的羟基增加了化合物的极性,或者与受体形成氢键,使其与肌肉烟碱乙酰胆碱受体结合更牢固,从而延长作用时间增强拮抗阻断效果。
本发明化合物具有以下通式:
其中
X表示碳键或NH-CH(C=O)-(CH2)3+n-NH-R5
n表示0、1或2,
R1、R4和R5彼此独立地表示氢、任选经取代的C1-C6-烷基、脒基或四-C1-C6-烷鎓
R2表示氢或任选经取代的C1-C6-烷基,
或者
R1和R2与它们所结合的残基一起表示5-至7-元的饱和环,
R3表示C1-C12-烷氧基、C1-C12-烷基氨基、任选经取代的芳基-C1-C6-烷基氨基、任选经取代的杂芳基-C1-C6-烷基氨基、任选经取代的芳基-C1-C6-烷氧基或任选经取代的杂芳基-C1-C6-烷氧基,并且
R6表示氢,或者当n是1时,也表示氨基,或者与R1以及R6和R1所结合的残基一起表示5-至7-元的饱和环。
本发明进一步涉及前面定义的化合物和盐作为可皮肤外用的活性物,可以制成各种剂型皮肤外用。
