摘要:
A process for preparing a compound represented by formula (Y1) or (Y2) [wherein Rx is an optionally substituted carbocyclyl lower alkyl, or the like] or a salt thereof, using a novel process for preparing a pyridone derivative represented by formula (X4) [wherein R1d is hydrogen, halogen, or the like; R2d is hydrogen, a lower alkyl optionally substituted with substituent E, or the like; R4d is a lower alkyl optionally substituted with substituent E, or the like; and R6d is a lower alkyl group optionally substituted with substituent group E, or the like].
摘要:
The invention relates to oxyimino compounds of (Formula I), and pharmaceutically acceptable salts, prodrugs and solvates thereof, wherein: Y is CO or SOm; Z is hydrogen, each optionally substituted lower alkyl, lower alkenyl, aryl, heterocyclyl etc. R1 and R2 are each independently hydrogen, each optionally substituted lower alkyl, lower alkenyl, cycloalkyl, aryl, heterocyclyl etc., each X is independently ═O, optionally substituted lower alkyl, cyano, nitro etc., m is 1 or 2, p is O, 1 or 2 and q is O or 1. The invention is also directed to the use compounds of Formula I to treat, prevent or ameliorate a disorder responsive to the blockade of calcium channels, and particularly N-type calcium channels. Compounds of the present invention are especially useful for treating pain.
