ABSTRACT
We report the development of molecular hybrids in which a nitrate group serving as nitric oxide (NO) donor is covalently joined to σ receptor ligands to give candidates for double-targeted cancer therapy. The compounds have been evaluated in radioligand binding assay at both σ receptors and selected compounds tested for NO release. Compounds 9, 15, 18, 19, and 21 were subjected to MTT test. Compound 15 produced a significant reduction of MCF-7 and Caco-2 cellular viability with comparable IC50 as doxorubicin, being also not toxic for fibroblast HFF-1 cells. Compound 15 has shown a σ1 receptor antagonist/σ2 receptor agonist profile. Two derivatives of compound 15 lacking the nitrate group did not induce a reduction of MCF-7 cellular viability, suggesting a potential synergistic effect between the σ receptors and the NO-mediated events. Overall, the combination of NO donor and σ receptors ligands provided compounds with beneficial effects for the treatment of cancer.
