SB 242084 (hydrochloride) Chemical Properties, Uses, Production

Description

Serotonin (5-hydroxytryptamine, 5-HT) is a neurotransmitter that activates specific receptors located primarily in the gut and central nervous system. SB-242084 is an antagonist of the 5-HT2C receptor (pKi = 9.0), with at least 100-fold more selectivity over other 5-HT, dopamine, or adrenergic receptors. In vivo, it is brain penetrant and has significant anxiolytic activity, without sedative, proconvulsant, or hyperphagic properties. SB-242084 has been used extensively in animal research to evaluate, for example, 5-HT2C receptor agonists and neurotransmitter receptor interactions in mice.

Uses

SB 242084 Hydrochloride is an antagonist of the SR-2C.

Definition

ChEBI: 6-chloro-5-methyl-N-[6-(2-methylpyridin-3-yl)oxypyridin-3-yl]-2,3-dihydroindole-1-carboxamide;dihydrochloride is an organic molecular entity, an indole alkaloid and a pyridine. It has a role as a receptor modulator.

in vivo

SB 242084 dihydrochloride (0.1-1 mg/kg; i.p.; single; 20 min pre-test) improves the behavior of rats in social interaction tests[1].
SB 242084 dihydrochloride (5 mg/kg; i.p.; single; 20 min pre-test) improves mCPP-induced hypophagia in rats[1].
SB 242084 dihydrochloride (5, 10 mg/kg; i.p.; single) increases the levels of basal dialysate dopamine (DA) and dihydroxyphenylacetic acid (DOPAC) in the nucleus accumbens of rats[3].
SB 242084 dihydrochloride (160-640 μg/kg; i.v.; single) dose-dependently and significantly increases the basal firing rate of VTA (ventral tegmental area) dopaminergic neurons, and the bursting activity is also enhanced in the same area, in vivo[3].

Animal Model:Male Sprague-Dawley (CD) rats[1].
Dosage:0.1-1 mg/kg
Administration:Intraperitoneal injection; single; 20 min pre-test
Result:Significantly increased the amount of time rats spent in social interaction over 15 min under brightly lit conditions and in an unfamiliartest box.
Animal Model:Male Sprague-Dawley (CD) rats(mCPP-induced hypophagia model)[1].
Dosage:5 mg/kg
Administration:Intraperitoneal injection; single; 20 min pre-test
Result:Significantly reduced the amount of food consumed by 23 h food-deprivedrats over a 1hr test period from the time of food presentation.
Animal Model:Rats[2].
Dosage:5, 10 mg/kg
Administration:Intraperitoneal injection; single
Result:Significantly increased basal dialysate dopamine (DA) and dihydroxyphenylacetic acid (DOPAC) in the nucleus accumbens.

5-HT2C Receptor: 9.0 (pKi)
