obstructive pulmonary disease (COPD). In this study, conjugates of desmosine and carrier proteins, such as bovine serum albumin (BSA) and keyhole limpet hemocyanin (KLH), with linkers were designed and prepared for the creation of an effective antibody to be used in the development of an enzyme-linked immunosorbent assay (ELISA) system. Synthesis of desmosine along with the linkers having appropriate
Desmosine 是一种弹性蛋白交联氨基酸,有望成为与弹性蛋白降解相关的疾病的有用生物标志物,包括慢性阻塞性肺病 (COPD)。在这项研究中,设计并制备了地氨丝蛋白和载体蛋白(如牛血清白蛋白 (BSA) 和匙孔血蓝蛋白 (KLH))与接头的结合物,用于产生用于开发酶的有效抗体。联免疫吸附试验(ELISA)系统。通过逐步和化学/区域选择性钯催化的 Sonogashira 和 Negishi 交叉偶联反应合成地氨辛以及具有适当长度的接头,该反应从具有保护基团的炔烃开始,经过九个步骤。随后,
