Chemical Name:N-(2,6-Diethylphenyl)-4,5-dihydro-1H-imidazol-2-amine
hydrochloride
Biological Activity:
α2-adrenoceptor agonist
that does not cross the blood brain barrier. Displays ~ 120-fold selectivity
for α2 receptors over α1 receptors and acts
predominantly at non-α2A-adrenoceptors which may be of the α2C subtype.
Antinociceptive; increases tail-flick latencies in Sasco and Harlan rats.
