A convergent strategy for the synthesis of peptide-oligonucleotide conjugates (POC) is presented. Chemoselective ligation of peptide to oligonucleotide was accomplished by oxime and thiazolidine formation. Oxime conjugation was performed by treating an oxyamine-containing peptide with an aldehyde-containing oligonucleotide or vice versa. Ligation by thiazolidine formation was achieved by coupling a
提出了一种融合策略,用于合成肽-寡核苷酸共轭物(POC)。通过肟和噻唑烷的形成来实现肽与寡核苷酸的化学选择性连接。通过用含醛的寡核苷酸处理含氧胺的肽进行肟偶联,反之亦然。通过将用半胱氨酸残基酰化的肽偶联至通过醛官能团衍生的寡核苷酸,实现噻唑烷形成的连接。对于这两种方法,不需要保护策略并且在温和的水性条件下以高收率获得缀合物。此外,肟连接被证明可用于直接缀合双链寡核苷酸。结合分子生物学工具,
