Design, synthesis and SAR analysis of novel selective sigma1 ligands (Part 2).

In order to investigate the molecular features involved in sigma receptors (sigma-Rs) binding, new compounds based on arylalkylaminoalcoholic, arylalkenyl- and arylalkylaminic scaffolds were synthesized and their affinity towards sigma(1)- and sigma(2)-Rs subtypes was evaluated. The most promising compounds were also screened for their affinity at micro-opioid, delta-opioid and kappa-opioid receptors. Biological results are herein presented and discussed.
