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.

专利号:US-11964260-B2 优先权日:2016-08-08 标题:Method for manufacturing ammonia synthesis catalyst, and method for manufacturing ammonia 发明人:HOSONO HIDEO; KITANO MASAAKI; YOKOYAMA TOSHIHARU; LI JIANG; KAWAMURA SHIGEKI; KISHIDA Kazuhisa 权利人:TOKYO INST TECH; TSUBAME BHB CO LTD 摘要:Provided is a method for manufacturing a catalyst with which it is possible to obtain a supported metal ammonia synthesis catalyst, in which there are restrictions in terms of producing method and producing facility, and particularly large restrictions for industrial-scale producing, in a more simple manner and so that the obtained catalyst has a high activity. This method for manufacturing an ammonia synthesis catalyst includes: a first step for preparing 12CaO·7Al 2 O 3 having a specific surface area of 5 m 2 /g or above; a second step for supporting a ruthenium compound on the 12CaO·7Al 2 O 3 ; and a third step for performing a reduction process on the 12CaO·7Al 2 O 3 supporting the ruthenium compound, obtained in the second step. This invention is characterized in that the reduction process is performed until the average particle diameter of the ruthenium after the reduction process has increased by at least 15% in relation to the average particle diameter of the ruthenium before the reduction process.
