Abstract
本发明涉及具有MC-Rs受体激动活性的四肽衍生物,其制备方法,含有它们的药物组合物,以及它们用于制备治疗肥胖及相关疾病以及性功能障碍等的药物的用途。
Description
技术领域
本发明涉及具有MC-Rs激动活性的四肽衍生物,非天然氨基酸的制备方法,含它们的药物组合物及它们用于制备治疗肥胖及相关疾病以及性功能障碍等疾病的药物的用途。
背景技术
随着生活节奏的加快、工作压力的加大,肥胖和性功能障碍都日益凸显出来,严重影响人们的生活质量。其中,肥胖是众所周知的导致动脉硬化、高血压、心脏病以及II型糖尿病等常见疾病的因素之一,而性功能障碍也严重影响到患者的身心健康和家庭幸福。
仅仅是轻微肥胖就会增加患糖尿病、高血压等疾病的几率,然而目前市场上用于治疗肥胖的有效药物只有少数几个,例如西布曲明(Sibutramine)和奥利司他(Orlistat);治疗性功能障碍的一线药物为西地那非等磷酸二酯酶抑制剂,但此类药物对女性患者无效,而且部分患者报道响应逐渐消失。因此新的治疗肥胖和性功能障碍的药物的研发是必须和当务之急的,具有十分广阔的前景。
α-MSH是一种源于前阿黑皮素(POMC)的线形十三肽。早在20世纪50年代,人们就发现,对狗、猴、猫以及兔子等中枢给予α-MSH后能引起其性兴奋,其作用机理是通过作用于黑皮素受体亚型MC-RS而产生调节性行为效应。研究表明,MC-Rs激动剂在治疗肥胖以及性功能障碍等方面有潜在的应用价值。
α-MSH是一个线状十三肽,C-端含有酰胺结构,N端乙酰化。α-MSH的一级结构如下:
Ac-Ser1-Tyr2-Ser3-Met4-Glu5-His6-Phe7-Arg8-Trp9-Gly10-Lys11-Pro12-V
al13-NH2
后来人们研究发现,α-MSH的最小活性序列为His6-Phe7-Arg8-Trp9。围绕着此核心序列,人们设计合成了一系列此类化合物,包括线性肽和环肽,在治疗肥胖以及性功能障碍方面有一定的效果。其中,PT-141等化合物对男女性功能患者都有较好疗效,甚至对部分西地那非无响应患者也有效,现即将进入三期临床研究阶段;而针对MC-Rs,也有许多用于治疗肥胖的候选药物在研发当中。
本发明的目的是寻找新的MC-RS激动剂。

实施例11:受体结合活性评价。
实验方法:cAMP释放实验(I125-cAMP放射免疫分析试剂盒),复管实验。
细胞株:瞬时表达MC3R/MC4R的HEK293细胞。
实验原理:I125-cAMP与cAMP抗血清结合可产生抗原抗体复合物,经离心去除游离未结合的I125-cAMP后,用γ-射线计数仪可测定沉淀中的同位素计数(B0)。药物作用下细胞释放的cAMP可与I125-cAMP共同竞争与cAMP抗血清的结合,由此使I125-cAMP与cAMP抗血清的结合物减少,因此使同位素计数降低(B)。
计算指标:结合抑制百分率=1-B/B0×100%
结合抑制百分率越高表示药物作用下cAMP释放越多,对给定受体而言也即激动活性越强。
药物筛选:选择20nM和100nM两个浓度,每个受试样品重复3次。结果见表1及表2。
