摘要: 为增加次血红素六肽(DhHP-6)的相对分子质量, 通过聚乙二醇(PEG)修饰合成mPEG-DhHP-6, 调整二甲基亚砜(DMSO)和磷酸盐(PBS)缓冲液的体积比可获得约95%的产率. mPEG-DhHP-6比DhHP-6的稳定性和活性均有提高. mPEG-DhHP-6可显著降低大鼠缺血再灌注后室性心动过速和心室颤动的发生率和持续时间, 可用于保护心血管系统.

Abstract:  In order to increase relative molecular weight of deuterohaemin-β-AlaHisThrValGluLys (DhHP-6), we synthesized mPEG-DhHP-6 through PEGylation, and adjusted the volume ratio of  dimethyl sulfoxide (DMSO)  and phosphate buffered saline (PBS) to achieve a  yield of around 95%. The stability and activity of of mPEG-DhHP-6 have been improved compared to DhHP-6. mPEG-DhHP-6 can significantly reduce the incidence and duration of ventricular tachycardia and ventricular fibrillation after ischemia-reperfusion in rats, and can be used to protect cardiovascular system.

Key words: PEGylation,  , deuterohaemin-β-AlaHisThrValGluLys (DhHP-6),  , myocardial ischemia-reperfusion
