The present invention provides a sulfonamide- or sulfonylurea-containing heterocyclic compounds. Specifically, it provides a heterocyclic compound represented by the formula (I), a pharmacologically acceptable salt thereof or a hydrate of them. In the formula, A is hydrogen atom, a halogen atom, a C1-C4 alkyl or alkoxy group which may be substituted with a halogen atom, or cyano group; B is an optionally substituted aryl group or monocyclic heteroaryl group, or: (wherein, the ring Q is an aromatic ring which may have nitrogen atom; and the ring M is a ring sharing a double bond with the ring Q, which ring may have a heteroatom; and the rings Q and M may share nitrogen atom); K is a single bond; T, W, X and Y are the same as or different from each other and each is ═C(D)— (wherein, D is hydrogen or a halogen atom) or nitrogen atom; U and V are the same as or different from each other and each is ═C(D)—, nitrogen atom, —CH2—, oxygen atom or —CO—; Z is a single bond or —CO—NH—; and R1 is hydrogen atom, etc.
