The present invention relates to compounds which are derivatives of cytisine or acetylcholine which exhibit activity as agonists, partial agonists or antagonists of nicotinic acetylcholine receptors and may be used in modulating these receptors and in treating mood disorders in patients in need of therapy.
Phenylcarbamate derivatives were synthesized and evaluated in radioligand binding assays for different nicotinicacetylcholinereceptor (nAChR) subtypes. Carbamate derivatives bearing a pyrrolidine or piperidine moiety 8-20 exhibited much lower affinity for alpha7* nAChR than the analogues in the quinuclidine series 21-25, although the same structural elements are present. Furthermore, in contrast
