ABSTRACT
Abstract N-(9,13b-dihydro-1H-dibenzo[c,f]imidazo[1,5-a]azepin-3-yl)-2-hydroxybenzamide (DDIAHB) is a new drug developed through molecular modelling and rational drug design by the molecular association of epinastine and salicylic acid. The present study was designed to assess the possible antinociceptive effects of DDIAHB on different pain models in male ICR mice. DDIAHB exerted the reductions of writhing numbers and pain behavior observed during the second phase in the formalin test in a dose-dependent manner. Moreover, DDIAHB increased the latency in the hot-plate test in a dose-dependent manner. Furthermore, intragastric administration DDIAHB caused reversals of decreased pain threshold observed in both streptozotocin-induced diabetic neuropathy and vincristine-induced peripheral neuropathy models. Additionally, intragastric pretreatment with DDIAHB also caused reversal of decreased pain threshold observed in monosodium urate-induced pain model. We also characterized the possible signaling molecular mechanism of the antinociceptive effect-induced by DDIAHB in the formalin model. DDIAHB caused reductions of spinal iNOS, p-STAT3, p-ERK and p-P38 levels induced by formalin injection. Our results suggest that DDIAHB shows an antinociceptive property in various pain models. Moreover, the antinociceptive effect of DDIAHB appear to be mediated by the reductions of the expression of iNOS, p-STAT3, p-ERK and p-P38 levels in the spinal cord in the formalin-induced pain model.
