Synthesis and pharmacological evaluation of a new 2-azabicyclo[3.3.0]octane derivative

As part of a research program aiming at the design, synthesis and pharmacological evaluation of a novel lead-candidates of neuroactive compounds, we describe herein the synthesis and the central profile of a new nebracetam analog having a 2-aza-bicyclo[3.3.0]octane system. The new derivative, designed on the basis of the conformational restriction concept, was synthesized in good yields exploring a diastereoselective reductive-amination and cyclization one-pot sequence. The pharmacological profile of this new compound, investigated by using path-clamp techniques on neurons of the CNS, indicated no effects on these cells.
