Probe for diseases with amyloid accumulation, amyloid-staining agent, remedy and preventive for diseases with amyloid accumulation and diagnostic probe and staining agent for neurofibrillary change
The present invention relates to a compound that is useful for treatment of, for example, hypertension, arteriosclerosis, bulimia and obesity because of having an antagonistic action to a neuropeptide Y receptor and is represented by formula (I)
[wherein R
1
represents hydrogen, cyano, or the like;
R represents a group represented by formula (II);
X
1
represents C
1-4
