30 new potent alpha 7 nAChR ligand synthesized derivatives synthesized.
2 identified leads exhibited a strong affinity (Ki = 2.3 and 3 nM).
Leads exhibit strict selectivity toward the α4β2 nicotinic receptor.
Leads induced a 5HT3 receptors Inhibition with Ki around 3 nM.
Rational design, synthesis, SAR are depicted.
