Certain aralkyl diazabicycloalkyl compounds are disclosed for treatment of CNS disorders, such as cerebral ischemia, psychosis, and convulsions. For example, compounds of interest are of the formula:

Aralkyl diazabicycloalkane derivatives for CNS disorders

The present invention relates to a class of compounds having affinity for certain cancer cells, e.g. lung carcinomas, colon carcinomas, renal carcinomas, prostate carcinomas, breast carcinomas, malignant melanomas, gliomas, neuroblastomas and pheochromocytomas. The compounds of the present invention can also bind with high specificity to cell surface sigma receptors and can therefore be used for diagnostic imaging of any tissue having an abundance of cells with sigma receptors. The present invention provides such compounds as agents for diagnostic imaging and for detecting and treating tumors containing the cancer cells described above.

Certain aralkyl diazabicycloalkyl compounds are disclosed for treatment of CNS disorders, such as cerebral ischemia, psychosis and convulsions. Compounds of particular interest are of the formula: ##STR1## wherein m is three or four; wherein z is selected from the group consisting of ##STR2## wherein when Z is ##STR3## n and p are integers of from one to four, with a sum of four or five, and when Z is ##STR4## n and p are integers of from one to three, with a sum of three or four; wherein A is selected from the group consisting of aryl, heteroaryl, aryloxy, heteroaryloxy, aralkoxy, heteroaralkoxy, arylamino, heteroarylamino, aralkylamino, heteroaralkylamino, arylthio, heteroarylthio, aralkylthio, and heteroaralkylthio; wherein any of the foregoing A groups can be further substituted with one or more substituents independently selected from the group consisting of hydrido, hydroxy, alkyl, cycloalkyl, cycloalkylalkyl, aralkyl, aryl, alkoxy, aryloxy, aralkoxy, alkoxyalkyl, halo, haloalkyl, hydroxyalkyl, cyano, amino, monoalkylamino, dialkylamino, carboxy, carboxyalkyl, alkanoyl, alkenyl and alkynyl; or a pharmaceutically acceptable salt thereof.

Methods for cancer imaging and therapy using benzamine compounds

Certain nitrogen-containing cyclohetero cycloalkylaminoaryl compounds are described for treatment of CNS disorders such as cerebral ischemia, psychoses and convulsions. Compounds of particular interest are of the formula: ##STR1## wherein each of R.sup.1, R.sup.4, R.sup.5, R.sup.6 and R.sup.7 is independently selected from hydrido, lower alkyl, benzyl, and haloloweralkyl;
