The present study was designed to investigate further the mechanisms involved in the antinociception caused by diphenyl diselenide in behavioral model of pain in mice. Diphenyl diselenide (1-100 mg/kg), given orally, produced significant inhibition of the biting behavior induced by intrathecal (i.t.) injection of glutamate (175 nmol/site) and N-methyl-d-aspartate (NMDA; 450 pmol/site), with mean ID(50) values of 45.92 (39.74-60.4) and 55.77 (36.52-77.5) mg/kg respectively. However, diphenyl diselenide completely failed to affect the nociception induced by alpha-amino-3-hydroxy-5-mehtyl-4-isoxazolepropionic acid (AMPA; 135 pmol/site), (+/-)-1-aminocyclopentane-trans-1,3-dicarboxylic acid (trans-ACPD; 50 nmol/site) and kainate (110 pmol/site). This compound also reduced the nociceptive response induced by substance P (SP) (135 ng/site, i.t.), interleukin 1beta (IL-1beta; 1 pg/site), tumor necrosis factor-alpha (TNF-alpha; 0.1 pg/site), bradykinin (BK; 0.1 microg/site) and capsaicin (30 ng/site) with mean ID(50) values of 16.22, 7.06, 6.06, 4.18 and 7.90 mg/kg, respectively. Together, these results indicate that diphenyl diselenide produced antinociception at spinal sites, with a possible interaction with glutamatergic pathways, more specifically via interaction with NMDA receptors, peptidergic or vanilloid systems.
