A series of compounds based on 7-{[4-(2-methylphenyl)piperidin-1-yl]methyl} -6,7,8,9-tetrahydro-5H-cyclohepta[b]pyridine-9-ol ((-)-8b), a potent and selective opioid receptor-like 1 (ORL1) antagonist, was prepared and evaluated using structure-activity relationship studies with the aim of removing its affinity to human ether-a-go-go related gene (hERG) K+ channel. From these studies, 101 was identified as an optimized structure with respect to ORL1 antagonist activity, and affinity to the hERG K+channel. Furthermore, 101 showed good in vivo antagonism with a wide therapeutic index in regards to adverse cardiovascular effects.

Provided are cycloalkanopyridine derivatives of formula [I]: [wherein the symbols are the same as those stated in the description]. The compounds act as a nociceptin receptor antagonist, and are useful as medicines for diseases associated with a nociceptin receptor, for example, as a reliever against tolerance to a narcotic analgesic; a reliever against dependence on or addiction to a narcotic analgesic; an analgesic enhancer; an antiobesitic or appetite suppressor; a treating or prophylactic agent for cognitive impairment and dementia/amnesia; an agent for treating developmental cognitive abnormality; a remedy for schizophrenia; an agent for treating neurodegenerative diseases; an anti-depressant or treating agent for affective disorder; a treating or prophylactic agent for diabetes insipidus; a treating or prophylactic agent for polyuria; or a remedy for hypotension.
