The present invention provides a compound of the formula:
wherein ring A is an optionally substituted aromatic hydrocarbon ring or aromatic heterocyclic ring; ring B is an optionally substituted aromatic hydrocarbon ring or aromatic heterocyclic ring; Z is an optionally substituted cyclic group or linear hydrocarbon group; R1 is a hydrogen atom, an optionally substituted hydrocarbon group or heterocyclic ring; R2 is an optionally substituted amino group; D is a bond or an optionally substituted divalent hydrocarbon group; E is a bond, —CON(Ra)—, —N(Ra)CO—, —N(Rb)CON(Rc)—, —N(Rd)COO—, —N(Re)SO2—, —COO—, —N(Rf)—, —O—, —S— —SO—, —SO2—,
(in which Ra, Rb, Rc, Rd, Re and Rf are respectively a hydrogen atom or an optionally substituted hydrocarbon group); G is a bond or an optionally divalent substituted hydrocarbon group; L is a divalent group;
ring B may form an optionally substituted non-aromatic condensed nitrogen-containing heterocyclic ring by combining with R2; X is two hydrogen atoms, an oxygen atom or a sulfur atom; is a single bond or a double bond, and Y is a nitrogen atom when is a double bond, or an oxygen atom, —N(R4)— (in which R4 is a hydrogen atom, an optionally substituted hydrocarbon group or an acyl group) or S(O)n (in which n is 0, 1 or 2) when is a single bond, or a salt thereof, which have somatostatin receptor agonistic action.
