Design, Synthesis and Discovery of Picomolar Selective α4β2 Nicotinic Acetylcholine Receptor Ligands
摘要:
Developing novel and selective compounds that desensitize alpha 4 beta 2 nicotinic acetylcholine receptors (nAChRs) could provide new effective treatments for nicotine addiction, as well as other disorders. Here we report a new class of nAChR ligands that display high selectivity and picomolar binding affinity for alpha 4 beta 2 nicotinic receptors. The novel compounds have K-i; values in the range of 0.031-0.26 nM and properties that should make them good candidates as drugs acting in the CNS. The selected lead compound 1 (VMY-2-95) binds with high affinity and potently desensitizes alpha 4 beta 2 nAChRs. At a dose of 3 mg/kg, compound 1 significantly reduced rat nicotine self-administration. The overall results support further characterizations of compound 1 and its analogues in preclinical models of nicotine addiction and perhaps other disorders involving nAChRs.
