The present invention provides a novel compound having an excellent corticotrophin-releasing-factor receptor antagonistic activity. That is, it provides a compound represented by the following formula or a salt thereof. Wherein R.sup.1 denotes a hydrogen atom, a C.sub.1-6 alkyl group, a C.sub.1-6 alkoxy group and the like; R.sup.2 denotes a halogen atom, a cyano group, a nitro group, a C.sub.1-10 alkyl group, a C.sub.2-10 alkenyl group, C.sub.2-10 alkynyl group and the like; R.sup.3 denotes a C.sub.6-14 aromatic hydrocarbon cyclic group or a 5- to 14-membered aromatic heterocyclic group, each of which may have a substituent; and X, Y and X are independent of each other and each denotes N or CR.sup.4 (wherein R.sup.4 denotes a hydrogen atom, a halogen atom, a cyano group, a nitro group, an optionally halogenated C.sub.1-6 alkyl group and the like) and, in this case, at least two of X, Y and Z denote CR.sup.4.
