  • Title: Synthesis and receptor binding studies of some new arylcarboxamide derivatives as sigma-1 ligands.
    Author: Zampieri D, Laurini E, Vio L, Golob S, Fermeglia M, Pricl S, Mamolo MG.
    Journal: Bioorg Med Chem Lett; 2014 Feb 15; 24(4):1021-5. PubMed ID: 24486131.
    Abstract:
    We describe here the synthesis and the binding interaction with σ1 and σ2 receptors of a series of new arylcarboxamide derivatives variously substituted on the aromatic portions. Maintaining a partial scaffold of a series of compounds previously synthesized by us, we evaluate the effect of the substitution on σ binding. The synthesized compounds have been tested to estimate their affinity and selectivity toward σ1 and σ2 receptors. Two out of 16 derivatives showed an interesting σ1 affinity (21.2 and 13.6 nM-compounds 2m and 2p) and a good selectivity (Ki(σ2)/Ki(σ1) >140 and >40, respectively).
