摘要:
Azulene derivatives represented by the following general formula (I) and salts thereof are useful as Na+-glucose cotransporter inhibitors in, for example, remedies for diabetes, etc., in particular, insulin-independent diabetes (type 2 diabetes), insulin-dependent diabetes (type 1 diabetes), etc., and remedies for various diabetes-related diseases such as insulin resistant disease and obesity. These compounds are characterized in that an azulene ring is bonded, either directly or via an optionally halogenated lower alkylene, to a benzene ring and the benzene ring is directly bonded to a sugar residue.
摘要:
A process for producing azulene derivatives useful as Na+-glucose cotransporter inhibitor easily and simply in high yield at a low cost which is industrially advantageous and excellent in environmental protection, characterized by subjecting at least one compound selected from among specific penta- and tetraacyl precursors of the azulene derivatives and salts of the precursors to reduction and deblocking to obtain a C-glycoside compound; and useful intermediates obtained in the above process.
摘要:
It is intended to provide a compound having an excellent effect of inhibiting dipeptidylpeptidase IV, and an excellent remedy for insulin-dependent diabetes (type 1 diabetes), in particular, insulin-independent diabetes (type 2 diabetes), insulin resistance disease and obesity based on the above effect.
