| Hazard Information | Back Directory | [Description]
B-HT 933 is an agonist of α2-adrenergic receptors (α2-ARs) with an EC50 value of 0.65 μM for contraction of canine sapheneous veins. It induces concentration-dependent inhibition of the twitch response in rat vas deferens and guinea pig ileum. B-HT 933 induces sedation and reduces motor activity in mice, an effect that is reversed by the α2-AR antagonist yohimbine . B-HT 933 decreases blood pressure and cardiac output in cats injected with 30 μg/kg intracisternally. It also exhibits antinociceptive effects in mice with ED50 values of 12.5, 20.5, and 6.1 mg/kg for the tail-immersion, tail-pinch, and acetic acid writhing tests, respectively. | [Uses]
B-HT 933 Dihydrochloride is a selective α2-adrenoceptor agonist and has less potent inhibitory effect on the sympathetic vasopressor responses in diabetic rats. | [in vitro]
b-ht 933, a selective α2-adrenoceptor agonist, contracts human subcutaneous resistance arteries by a mechanism largely dependent on the influx of extracellular ca2+, probably through voltage-operated calcium channels. this action involves a pertussis toxin-sensitive g protein, possibly gq [1]. | [in vivo]
the dose-related effects of the selective α2-adrenoceptor agonist b-ht 933 on the body temperature of untreated and reserpine-treated mice were investigated. in untreated mice b-ht 933 induced a dose-related hypothermia. the highest dose of b-ht 933 elicited a marked hypothermia, whereas the maximal hypothermic effect of clonidine was less pronounced and reached a plateau at a dose of 0.5 mg/kg [2]. | [IC 50]
