Page/Page column 96, (2009/01/24)
The present invention relates to di(hetero)arylcyclohexane derivatives of the formula (I), in which Ar1, Ar2, R1 and R2 have the meanings indicated in the claims. The compounds of the formula (I) are valuable pharmaceutical active compounds which inhibit ATP-sensitive potassium channels in the heart muscle and are suitable, for example, for the treatment of disorders of the cardiovascular system such as arrhythmias or a decreased contractility of the heart, such as can occur, for example, in coronary heart disease, cardiac insufficiency or cardiomyopathies. In particular, they are suitable for the prevention of sudden cardiac death. The invention furthermore relates to processes and intermediates for the preparation of the compounds of the formula (I), their use and pharmaceutical compositions comprising them.

Investigation of central nervous system activity of phenylcyclohexylamines was continued by preparation of "reversed" analogues.Following the unexpected finding of analgesic activity with 1-(dimethylamino)-1-phenylcyclohexylamine, the SAR of the series was investigated.Synthesis starts by double Michael reaction of acrylate on arylacetonitriles.Following cyclization, decarboxylation, ketalization, and saponification, the geminally substituted acid is rearranged to the isocyanate by means of (C6H5O)2PON3.Isocyanates were then converted to the title compounds.Analgesic activity is very sensitive to the nature and position of the substituent on the aromatic ring.The most potent compounds in this series (p-CH3, p-Br) showed 50percent the potency of morphine.Deletion of the ring oxygen abolishes activity.

A class of new 4-amino-4-arylcyclohexanones, their ketals, and acid addition salts have been synthesized and found to be useful for relieving pain in animals. Their analgesic activity appears to be of high order, and in addition some exhibit narcotic antagonist activity that is useful in modifying the cardiovascular, respiratory, and behavioral depression caused by other analgesics. Several show mixed analgesic and narcotic antagonist activity. Preferred compounds of the class are 4-(m-hydroxyphenyl)-4-dimethylaminocyclohexanone ethylene ketal, and 4-(m-hydroxyphenyl)-4-(n-butylmethylamino)cyclohexanone ethylene ketal as free bases and as their hydrochloride salts. Processes for synthesis and intermediates are described. Unit dosage forms and therapeutic treatments are disclosed.
