There is provided heterocyclic compounds of the following formula (I):
1
in which,
A is optionally substituted alkyl group, optionally substituted aryl group or optionally substituted heterocyclic group;
B
1
and B
2
are, hydrogen atom, alkyl group or hydroxyl group; or combined together to represent carbonyl group;
X is oxygen atom, sulfur atom, carbon atom or nitrogen atom;
dotted line shows either presence or absence of bond;
n is integer of 1 or 2; and
the group —X—Y— represents optionally substituted alkylene or cyclic alkenylene bond;
or a pharmaceutically acceptable salt thereof.
These compounds have good affinity for &agr;4&bgr;2 nicotinic acetylcholine receptors and activate the same to thereby exert a preventive or therapeutic effect on cerebral dysfunction.

Syntheses and evaluation of pyrrolidin-2-imines and 1,3-thiazolidin-2-imines as inhibitors of nitric oxide synthase (NOS) are discussed. An extensive SAR was established for pyrrolidin-2-imines class of compounds. The amidines came out as the most potent inhibitors in addition to displaying selectivity. (C) 2004 Elsevier Ltd.
