AbstractNicotine acethylcholine receptors (nAChRs) play critical roles in cognitive processes, neuroprotection and inflammation. Results: According to their substituents, 1,3-diphenylpropan-1-one derivatives act as α7 nAChRs negative allosteric modulators (NAM, OMe) or Type I positive allosteric modulators (PAMs, OH). Compounds 7 and 31 were the most effective (989 and 666% enhancement of ACh-induced currents) and potent (EC: 12.9 and 6.85 μM) PAMs. They exhibited strong radical scavenging values. Compound 31, selective over other neuronal nAChR subtypes and with acceptable pharmacokinetic profile, showed antinociceptive effects in a model of inflammatory pain. Conclusion: Compound 31 is a novel, potent and selective α7 nAChR PAM, displaying antioxidant and analgesic activities. The 1,3-diphenylpropan-1-one scaffold could be the base toward more advanced type I PAMs for the treatment of nAChR-mediated diseases.
