Aminoacetyl-acenaphthenes

A 3,6-bis-basic ketone of acenaphthene having the formula:

• ##STR18## wherein A is a straight or branched alkylene chain having from 1 to 6 carbon atoms;
• and Y is selected from the group consisting of:
• a. ##STR19## wherein R.sub.1 and R.sub.2 are individually selected from the group consisting of hydrogen, lower alkyl having from 1 to 6 carbon atoms, cycloalkyl having from 3 to 6 carbon atoms, alkenyl having from 3 to 6 carbon atoms in which the unsaturation is in a position other than the 1-position of the alkenyl group;
• b. ##STR20## wherein n is an integer of from 4 to 6, and R.sub.3 is selected from the group consisting of hydrogen, lower alkyl having from 1 to 4 carbon atoms, phenyl and benzyl in which said R.sub.3 group is linked to any of the heterocyclic carbon atoms;
• c. ##STR21## wherein X is selected from the group consisting of oxygen and NR.sub.4, in which R.sub.4 represents hydrogen or a lower alkyl group having from 1 to 4 carbon atoms;
• and the pharmaceutically acceptable salts thereof.
