专利号:US-2024124910-A1 优先权日:2021-02-02 标题:Ribosome-mediated polymerization of novel chemistries 发明人:JEWETT MICHAEL CHRISTOPHER; LEE JOONGOO; ANSLYN ERIC V; CORONADO JAIME; LIM JONGDOO 权利人:UNIV NORTHWESTERN; UNIV TEXAS 摘要:Disclosed are methods, systems, components, and compositions for synthesis of sequence defined polymers. The methods, systems, components, and compositions may be utilized for incorporating novel substrates that include non-standard amino acid monomers and non-amino acid monomers into sequence defined polymers. As disclosed herein, the novel substrates may be utilized for acylation of tRNA via flexizyme catalyzed reactions. The tRNAs thus acylated with the novel substrates may be utilized in synthesis platforms for incorporating the novel substrates into a sequence defined polymer.
专利号:US-2010273787-A1 优先权日:2007-11-15 标题:Kynurenine-aminotransferase inhibitors 发明人:SCHWARCZ ROBERT; KAJII YASUSHI; ONO SHIN-ICHIRO 权利人:SCHWARCZ ROBERT; KAJII YASUSHI; ONO SHIN-ICHIRO 摘要:Compounds of formula (I): prodrug derivatives and/or pharmaceutically acceptable salt thereof, selectively inhibit the enzyme kynurenine aminotransferase, thereby reducing the synthesis of kynurenic acid. The compounds are used for the treatment of psychiatric and neurological diseases which benefit from an increase in glutamatergic and/or cholinergic neurotransmission, such as schizophrenia, depression, bipolar illness, anxiety and Alzheimer's disease. Furthermore, the compounds of the invention are useful for stimulating attention, memory and other cognitive processes in normal individuals of any age, including children, adolescents and the elderly. Additionally, the compounds of the invention are also useful for treatment of patients suffering from malaria by preventing parasite gametogenesis and fertility based on reduction of xanthurenic acid formation from its bioprecursor 3-hydroxy kynurenine.
参考标题:The Synthesis Of Amino Acids By Reaction Of An Electrophilic Glycine Cation Equivalent With Neutral Carbon Nucleophiles 作者:Martin J. O'Donnell,William D. Bennett |发布日期:1988.1 摘要:Seven Neutral Carbon Nucleophiles (Active Aromatics, Allylsilanes, And A Silyl Enol Ether) Were Reacted With The Glycine Cation Equivalent 12 In The Presence Of Ticl4To Yield α-Substituted Amino Acid Derivatives In Moderate Yield (1 - 61.5 Mmolar Scale). Deprotection Of The Schiff Base Ester Products Led To The Corresponding Amino Acids.
