The present invention provides a novel heterocyclic compound. A heterocyclic compound represented by general formula (1) wherein, R1 and R2, each independently represent hydrogen; a phenyl lower alkyl group that may have a substituent(s) selected from the group consisting of a lower alkyl group and the like on a benzene ring and/or a lower alkyl group; or a cyclo C3-C8 alkyl lower alkyl group; or the like; R3 represents a lower alkynyl group or the like; R4 represents a phenyl group that may have a substituent(s) selected from the group consisting of a 1,3,4-oxadiazolyl group that may have e.g., halogen or a heterocyclic group selected from pyridyl group and the like; the heterocyclic group may have at least one substituent(s) selected from a lower alkoxy group and the like or a salt thereof.
本发明提供了一种新的杂环化合物。该杂环化合物由通式(1)表示,其中,R1和R2分别独立地表示氢;苯基较低烷基基团,可能在苯环和/或较低烷基基团上具有选自较低烷基基团等的取代基;或环C3-C8烷基较低烷基基团;或类似物;R3表示较低炔基基团或类似物;R4表示苯基,可能在其中具有选自1,3,4-噁二唑基团(例如,卤素或选自吡啶基团等的杂环基团)的取代基;该杂环基团可以具有至少一个选自较低烷氧基等的取代基或其盐的取代基。
