标题 :SYNTHESIS OF DGJNAc FROM D-GLUCURONOLACTONE AND USE TO INHIBIT ALPHA-N-ACETYLGALACTOSAMINIDASES
发明人：FLEET GEORGE WILLIAM JOHN; BUTTERS TERRY DOUGLAS
权利人:UNIV OXFORD; FLEET GEORGE WILLIAM JOHN; BUTTERS TERRY DOUGLAS
摘要:A convenient and scalable synthesis of DGJNAc ID from D-glucuronolactone in an overall yield of 20% is provided. DGJNAc is the first highly potent and specific competitive inhibitor of GalNAcases. DGJNAc ID is also a competitive inhibitor of -hexosaminidases. Synthesis and activity of L-DGJNAc IL is also shown. The use of DGJNAc as a potent and specific inhibitor of GalNAcases will allow useful investigation and treatment of a number of diseases, including Schindler Disease.
