ABSTRACT:
The present invention provides bioactive compounds of the general formula: ##STR1## wherein R is H, (C.sub.1 -C.sub.4)alkyl, (C.sub.3 -C.sub.6)cycloalkyl, (C.sub.3 -C.sub.6)cycloalkyl(C.sub.1 -C.sub.4)alkyl, allyl, (C.sub.6 -C.sub.10)aryl or (C.sub.1 -C.sub.4)alkylCO.sub.2 Y; Y is H, (C.sub.1 -C.sub.4)alkyl or (C.sub.6 -C.sub.10)aryl; each X is individually H, (C.sub.1 -C.sub.4)alkyl, (C.sub.6 -C.sub.10)aryl, (C.sub.3 -C.sub.6)cycloalkyl(C.sub.1 -C.sub.4)alkyl, or (C.sub.3 -C.sub.6)cycloatkyl; the bond represented by--is present or is absent; and the pharmaceutically acceptable salts thereof, and methods for using said compounds to stimulate receptors in the mammalian nervous systems.
