Dexmedetomidine is a potent agonist of a2 adrenergic and very specific experience of receptor-binding selectivity has a t ratio Ratio A2/A1 of 1600, or four hours Ago than clonidine. It strongly activates all three subtypes of a2-adrenergic receptor, all sensitive to the pertussis toxin Gi / o-coupled receptors are linked. The best known effects of dexmedetomidine in the brain is a AB1010 pr Synaptic inhibition of noradrenaline release and cell firing in noradrenergic neurons, but only a small fraction of a2 adrenergic receptors appears to be pr Synaptic. Consequently, several pharmacological effects of dexmedetomidine independent Ngig by inhibiting the release of norepinephrine. Recognition of this is that Re U 14th December 2007, first February 2008, online at all Published third M accepted March, sent 2008 to: Professor L Peng, College of Basic Medical Sciences, China Medical University, No.

In addition to the effects of hypnotics / sedatives and analgesics, low concentrations of dexmedetomidine, with one exception, have been found repeatedly to neuroprotective properties in experimental cerebral ish Excitotoxic neuronal chemistry and Sch have Apology.
The mechanism of neuroprotection is not known, but the neuroprotective effect of dexmedetomidine can be detected even under conditions where it does not reduce ish Chemistry-induced increase in brain norepinephrine. Target cells in the CNS adrenergic a2 job intersection go Ren astrocytes, which will in particular focus on the expression of subtype A2A / D-adrenoceptors. We previously reported that dexmedetomidine in the concentration range 25 nM, 100 causes phosphorylation of ERK1 and ERK2 in cultured mouse astrocytes, phosphorylation of ERK1 / 2 occurred rapidly, reached at 20 min and decreased 40 min after stimulation. Based on the inhibition of phosphorylation by tyrphostin AG 1478, an inhibitor of tyrosine kinase and by heparin, an antagonist of epidermal growth factor heparin-binding, we suggested that this effect is the result of the receptor transactivation is epidermal growth factor. Trans-activation, activation of the connection of certain G-protein coupled receptors confinement, Lich a2-adrenoceptor with ERK two stages, as demonstrated elegantly in transfected COS-7 cells. In the first step, the BG-subunits of the activation
