We describe here the synthesis and the binding interaction with sigma(1) and sigma(2) 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 r binding. The synthesized compounds have been tested to estimate their affinity and selectivity toward sigma(1) and sigma(2) receptors. Two out of 16 derivatives showed an interesting sigma(1) affinity (21.2 and 13.6 nM-compounds 2m and 2p) and a good selectivity (K-i(sigma(2))/K-i(sigma(1)) >140 and >40, respectively).
