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, <CHEM> Äwherein, T<1> 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 <CHEM> represents a double bond or a single bond; X<3> denotes an oxygen atom or a sulfur atom; X<1> denotes a C2-6 alkynyl group which may have substituents; Z<1> denotes a nitrogen atom or the formula -CR<3>=; Z<2> and Z<3> each independently denote a nitrogen atom, the formula -CR<1>=, a carbonyl group, or the formula -NR<2>-; R<1>, R<2>, R<3>, and X<2> each independently denote a C1-6 alkyl group which may have substituents, and suchÜ. |
