摘要

Compounds represented by the general formula (I): wherein Ar<1> and Ar<2> are each aryl or heteroaryl; R<1> is lower cycloalkyl, -Ar<3>, or a group of the general formula (a), (b) or (c): or and R<2> and R<3> are each hydrogen, lower cycloalkyl, lower alkenyl, or optionally substituted lower alkyl (with the proviso that when R<2> and R<3> are simultaneously hydrogen, Ar<1>, Ar<2> and R<1> do not simultaneously represent unsubstituted phenyl). The compounds are useful as treating agents for various NPY-related diseases, for example, circulatory diseases including hypertension, kidney diseases, cardiac diseases, vasospasm and arteriosclerosis; central nervous system diseases including hyperphagia, depression, anxiety, convulsion, epilepsy, dementia, pain, alcohol dependence, and withdrawal symptoms due to abstinence from drugs; metabolic diseases including obesity, diabetes, hormonal disorders, hypercholesterolemia, and hyperlipidemia; sexual dysfunction and reproductive function disorders; digestive diseases including enterokinetic disorders; respiratory diseases; inflammation; or glaucoma.
