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 alkynyl 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优异的 DPPIV 抑制活性的新型化合物。本发明提供了通式(I)所代表的化合物、其盐类或其水合物、
其中
T1 代表环中有 1 或 2 个氮原子的单环或双环 4 至 12 元杂环,该杂环可以有取代基;在式(I)中,下式
