Description

SB-224289 was originally developed by SmithKline, now known as GlaxoSmithKline. It was identified as an antagonist of the 5-hydroxytryptamine receptor 1B (5-HT1B) and subsequently investigated for potential antidepressant activity, although no human trials have been reported. Interestingly, SB-224289 was also found to exhibit antagonistic activity for the antifungal mechanism of Marine Depsipeptide Papuamide A in Candida albicans; although the specific mechanism of action remains unknown.

Sample Use Guides

In Vivo Use Guide
The regulation of extracellular 5-HT1B receptors by SB-224289 was investigated in Guinea pigs which were dosed via intraperitoneal injection at a concentration of 4 mg/kg. SB-224289 had no effect on 5-HT levels in frontal cortex or striatum. In the dentate gyrus SB-224289 significantly increased extracellular 5-HT, reaching maxima of 151+/-19% of basal levels.
Route of Administration: Intraperitoneal
In Vitro Use Guide
Human 5-HT1B and 5-HT1D receptors were stably transfected into the Chinese Hamster Ovary (ACC098) cell line. Competition studies were performed to determine the affinity of SB-224289 at both h5-HT1B and h5-HT1D receptor subtypes. SB-224289 was also equal to or greater than 75 fold selective for the h5-HT1B receptor over the other human 5-HT receptor subtypes exhibiting a pKi of 8 for human 5HT1B.
