Val-Val-Pro-Gln (valyl-valyl-prolyl-glutamine) is a small but highly conserved sequence present in all elastins. We describe its synthesis by mixed anhydride solution chemistry as an alternative to solid-phase peptide synthesis (SPPS). The molecular structure of the tetrapeptide in solution was investigated by classical spectroscopy, such as circular dichroism (CD), nuclear magnetic resonance (NMR)
Val-Val-Pro-Gln(缬氨酰-缬氨酰-脯氨酰-谷氨酰胺)是存在于所有弹性蛋白中的一个小但高度保守的序列。我们通过混合酸酐溶液化学描述其合成,作为固相肽合成 (SPPS) 的替代方法。溶液中四肽的分子结构通过经典光谱学研究,例如圆二色性 (CD)、核磁共振 (NMR) 和傅里叶变换红外光谱 (FTIR)。Val-Val-Pro-Gln 的生物活性通过溴脱氧尿苷 (BrdU) 掺入试验与正常人皮肤成纤维细胞进行评估。这种小肽可能在组织分解和重塑期间从弹性蛋白多肽链中释放出来,从而在控制基质代谢方面发挥关键作用。(© Wiley-VCH Verlag GmbH & Co.
