The present invention provides a oxazole compound represented by Formula (1), or a salt thereof:
wherein R1 is an aryl group which may have one or more substituents; R2 is an aryl group or a nitrogen atom-containing heterocyclic group each of which may have one or more substituents; and W is a divalent group represented by —Y1-A1- or —Y2—C(═O)— wherein Y1 is a group such as —C(═O)—, A1 is a group such as a lower alkylene group, and Y2 is a group such as a piperazinediyl group. The oxazole compound has a specific inhibitory action against phosphodiesterase 4.
本发明提供一种由式(1)表示的噁唑酮化合物或其盐:
其中,R1是一个芳基基团,可能具有一个或多个取代基;R2是一个芳基基团或氮原子含量的杂环基团,每个基团可能具有一个或多个取代基;W是一个由—Y1-A1-或—Y2—C(═O)—表示的二价基团,其中Y1是如—C(═O)—这样的基团,A1是如较低的烷基链这样的基团,Y2是如哌嗪二基基团这样的基团。该噁唑酮化合物对磷酸二酯酶4具有特定的抑制作用。
