BHT-920-induced contractions were inhibited by the alpha (2)-adrenoceptor antagonist yohimbine (17-Hydroxy-yohimban-16-carboxylic acid methyl ester hydrochloride; pA (2)=8.7+/-0.5), but not by the alpha (1)-adrenoceptor antagonist prazosin (1-[4-Amino-6,7-dimethoxy-2-quinazolinyl]-4-[2-furanylcarbonyl]-piperazine hydrochloride; 300 nM).

In contrast, ARC-239 (2-(2,4-(o-piperazine-1-yl)-ethyl-4,4-dimethyl-1,3-(2H, 4H) disoguinolinedione chloride), a selective alpha (2B)-antagonist, had no effect on the release and failed to prevent the effect of dexmedetomidine.

J Med Chem. 2006 Oct 19;49(21):6351-63.

The 3-position on the piperazine ring was also found to play an appreciable role, as substitutions in that position exerted a significant and stereospecific beneficial effect on the alpha (2C)-adrenoceptor affinity and potency.
