专利号:WO-2024258613-A9 优先权日:2023-06-16 标题:Tetrachlorovancomycin and derivatives 发明人:BOGER DALE 权利人:SCRIPPS RESEARCH INST 摘要:A total synthesis of a new class of vancomycin analogues of reduced synthetic complexity was developed. The synthesis, achieved by the addition of two aryl chloride substituents to provide tetrachlorovancomcyin aglycon (Compound II), tetrachlorovancomcyin (Compound I ), and their derivatives, permitted a streamlined total synthesis of the new class of glycopeptide antibiotics by removing atropisomer stereochemical control and enabled the simultaneous and further activated SNAr macrocyclizations that establish the tricyclic skeleton of Compound I. In addition to the antimicrobial evaluation of tetrachlorovancomycin (Compound I), the preparation of key binding pocket and peripherally-modi fied derivatives, which overcome vancomycin resistance and introduce independent and synergistic mechanisms of action, revealed their exceptional antimicrobial potency and provide the foundation for use of this new class of synthetic glycopeptide analogues. Also disclosed are a pharmaceutical composition containing bactericidal amount of tetrachlorovancomycin, a derivative thereof or a salt of either dissolved or dispersed in a pharmaceutically acceptable diluent.
