摩尔计算器

Lys-psi(CH2NH)-Trp(Nps)-OMe是一种赖氨酸-色氨酸(Nps)的假二肽类似物。它通过将Lys-Trp(Nps)分子中的肽键替换为氨基亚甲基键而获得，具有镇痛活性。Lys-psi(CH2NH)-Trp(Nps)-OMe在小鼠脑室内给药后可诱导剂量依赖性和纳洛酮可逆的镇痛作用，其镇痛效果比原化合物持续时间更长。它能保护甲硫氨酸脑啡肽免受大鼠纹状体切片的降解，并与低剂量阿片肽结合产生镇痛作用。Lys-psi(CH2NH)-Trp(Nps)-OMe在体内和体外都能有效抑制脑内氨肽酶活性。这种假二肽对蛋白酶水解的抗性增强可能解释了其延长的镇痛活性。

生物活性

Lys-psi(CH2NH)-Trp(Nps)-OMe is a lysine-tryptophan (Nps) pseudodipeptide analog. It is obtained by replacing the peptide bond in the Lys-Trp(Nps) molecule with an aminomethylene bond and has analgesic activity. Lys-psi(CH2NH)-Trp(Nps)-OMe induces a dose-dependent and naloxone-reversible analgesia after intracerebroventricular administration in mice, and its analgesic effect lasts longer than that of the original compound. It protects methionine enkephalin from degradation in rat striatal slices and binds to low-dose opioid peptides to produce analgesia. Lys-psi(CH2NH)-Trp(Nps)-OMe effectively inhibits brain aminopeptidase activity both in vitro and in vivo. The enhanced resistance of this pseudodipeptide to proteolysis may explain its prolonged analgesic activity.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
