Abstract

A new series of spirocyclic σ receptor (σR) ligands were prepared and studied. Most were found to have a high affinity and selectivity for σ1 R; three compounds were shown to be σ1 R agonists, while another proved to be the only σ1 R antagonist. Only one of the σ1 R agonists (BS148) also exhibited σ2 R selectivity and was able to inhibit the growth of metastatic malignant melanoma cell lines without affecting normal human melanocytes. The antiproliferative activity of this compound suggested an σ2 R agonist profile. Further, preliminary investigations indicated that the mechanism of metastatic malignant melanoma cell death induced by BS148 is due, at least in part, to Apoptosis.
