O článku:
SNC80 was designed as a highly selective nonpeptide delta opioid receptor (DOR) agonist. Antidepressant-like and antinociceptive effects of this compound were demonstrated in animal models. Naltrindole was synthetized as a highly selective DOR antagonist. Its antitussive and antinociceptive effects were reported. Observed effects of SNC80 and naltrindole may be accompanied by changes in neuronal excitability including modulation of voltage-dependent ion channels. We investigated possible DOR-independent modulation of neuronal sodium, calcium and potassium currents by both agents. NG108-15 cells lacking expression of DOR protein were used as model of neuronal cells. Cells were differentiated into neuronal phenotype by exposure to dibutyryl cyclic-AMP (dbcAMP). Lack of DORs expression in NG108-15 cells and the presence of DOR expression in brain and neuronal cultures were demonstrated by Western blot analysis. Both SNC80 and naltrindole exerted low to moderate modulatory effects on voltage-dependent ion currents. SNC80 weakly inhibited sodium current, potentiated calcium current, and did not act on potassium channels. Naltrindole inhibited sodium current, did not act on calcium current and inhibited potassium current at a high concentration. Such effects should be taken into account when these compounds are used for investigation of DOR-mediated signaling pathways.
