The objective of this invention is to provide novel compounds that show excellent DPPIV-inhibiting activity. The present invention provides compounds represented by the general formula (I), salts thereof, or hydrates thereof,
[wherein,
T1 stands for a monocyclic or bicyclic 4 to 12-membered heterocycle having 1 or 2 nitrogen atoms in the ring, which may have substituents; in formula (I), the following formula
represents a double bond or a single bond; X3 denotes an oxygen atom or a sulfur atom; X1 denotes a C2-6 alkyl group which may have substituents; Z1 denotes a nitrogen atom or the formula —CR3=; Z2 and Z3 each independently denote a nitrogen atom, the formula —CR1=, a carbonyl group, or the formula —NR2—; R1, R2, R3, and X2 each independently denote a C1-6 alkyl group which may have substituents, and such].
本发明的目的是提供具有出色的DPPIV抑制活性的新化合物。本发明提供了由通式(I)表示的化合物,其盐或水合物,其中,T1代表具有1或2个氮原子的单环或双环4到12成员杂环,该环可能具有取代基;在式(I)中,以下式表示双键或单键;X3表示氧原子或硫原子;X1表示C2-6烷基,该烷基可能具有取代基;Z1表示氮原子或公式—CR3=;Z2和Z3各自独立地表示氮原子,公式—CR1=,羰基或公式—NR2—;R1、R2、R3和X2各自独立地表示C1-6烷基,该烷基可能具有取代基。
