This study describes the design and synthesis of endomorphin-1 analogs containing C-terminal aromatic α-methyl-β-amino acids and an N-terminal native tyrosine or 2,6-dimethyl-tyrosine. We show that, in comparison with the parent peptide, these analogs exhibit improved bioactivity and blood–brain barrier penetration after intravenous administration, and have a lower tendency to induce constipation and
这项研究描述了含有C末端芳香族α-甲基-β-氨基酸和N末端天然酪氨酸或2,6-二甲基酪氨酸的内啡肽-1类似物的设计和合成。我们显示,与母体肽相比,这些类似物在静脉内给药后表现出更高的生物活性和血脑屏障渗透性,并且比吗啡具有更低的诱发便秘和镇静作用的趋势。
