权利人:WARNER LAMBERT CO
摘要:The present invention relates to novel tri- and tetrasubstituted pyrones and related structures which potently inhibit the HIV aspartyl protease blocking HIV infectivity. The pyrone derivatives are useful in the development of therapies for the treatment of bacterial and viral infections and diseases, including AIDS. The present invention is also directed to methods of synthesis of multifunctionalized pyrones and of related structures.
