专利号:US-2023212216-A1 优先权日:2019-12-20 标 题:Synthesis of lactone derivatives and their use in the modification of proteins 发明人:MORRIS ALEXANDER REDFERN; SUTOV GRIGORIJ; BRUNE KARL DIETRICH 权利人:GENIE BIOTECH UK LTD 摘要:Site-specific modifications of proteins are desirable in biotechnological applications such as biopharmaceuticals, immunotherapy, vaccines, and are useful in chemical biology. Gluconoylation is a non-enzymatic, covalent, post-translational modification commonly observed on N-terminal His-Tags bearing proteins. We synthesized glucono-1,5-lactone derivatives, including azido variants for selective acylation. High yield acylation is achieved by simply mixing derivatives with target protein amidst diverse conditions of temperatures, aqueous buffers, excipients, or complex cell lysate.
