Two types of pyridoxal analogs, azido pyridoxal (PL-N3) and carboxyl pyridoxal (PL-COOH), were developed as novel bifunctional bioorthogonal molecules. These molecules showed fast imine formation with hydrazinyl groups and stable covalent linkages via azido/carboxyl groups, and thus were of great use for site-specific peptide and protein modifications.
已开发出两种类型的吡molecules醛类似物,叠氮基吡ido醛(PL-N 3)和羧基吡ido醛(PL-COOH),作为新型的双功能生物正交分子。这些分子显示具有肼基的快速亚胺形成以及通过叠氮基/羧基的稳定共价键,因此对于位点特异性肽和蛋白质修饰非常有用。
