專利名稱::黑色素皮質(zhì)激素受體七肽類激動劑及其制備方法和用途的制作方法
技術(shù)領(lǐng)域:
:本發(fā)明涉及具有MC-Rs激動活性的七肽衍生物,非天然氨基酸的制備方法,含它們的藥物組合物及它們用于制備治療肥胖及相關(guān)疾病以及性功能障礙等疾病的藥物的用途。
背景技術(shù):
:隨著生活節(jié)奏的加快、工作壓力的加大,肥胖和性功能障礙都日益凸顯出來,嚴重影響人們的生活質(zhì)量。其中,肥胖是眾所周知的導(dǎo)致動脈硬化、高血壓、心臟病以及II型糖尿病等常見疾病的因素之一,而性功能障礙也嚴重影響到患者的身心健康和家庭幸福。僅僅是輕微肥胖就會增加患糖尿病、高血壓等疾病的幾率,然而目前市場上用于治療肥胖的有效藥物只有少數(shù)幾個,例如西布曲明(Sibutramine)和奧利司他(0rlistat);治療性功能障礙的一線藥物為西地那非等磷酸二酯酶抑制劑,但此類藥物對女性患者無效,而且部分患者報道響應(yīng)逐漸消失。因此新的治療肥胖和性功能障礙的藥物的研發(fā)是必須和當(dāng)務(wù)之急的,具有十分廣闊的前景。ot-MSH是一種源于前阿黑皮素(P0MC)的線形十三肽。早在20世紀50年代,人們就發(fā)現(xiàn),對狗、猴、貓以及兔子等中樞給予ot-MSH后能引起其性興奮,其作用機理是通過作用于黑皮素受體亞型MC-RS而產(chǎn)生調(diào)節(jié)性行為效應(yīng)。研究表明,MC-Rs激動劑在治療肥胖以及性功能障礙等方面有潛在的應(yīng)用價值。ot-MSH是一個線狀十三肽,C-端含有酰胺結(jié)構(gòu),N端乙?;t-MSH的一級結(jié)構(gòu)如下Ac-Ser^Tyr2-Ser3-Met4-Glu5-His6-Phe7-Arg8-Trp9-Gly"-Lys"-Pro"-Val13-NH2后來人們研究發(fā)現(xiàn),ot-MSH的最小活性序列為His6-Phe7-Arg8-Trp9。圍繞著此核心序列,人們設(shè)計合成了一系列此類化合物,包括線性肽和環(huán)肽,在治療肥胖以及性功能障礙方面有一定的效果。其中,PT-141等化合物對男女性功能患者都有較好療效,甚至對部分西地那非無響應(yīng)患者也有效,現(xiàn)即將進入三期臨床研究階段;而針對MC-Rs,也有許多用于治療肥胖的候選藥物在研發(fā)當(dāng)中。本發(fā)明的目的是尋找新的MC-Rs激動劑。
