Application

SB 242084 dihydrochloride hydrate was used to study the role of 5-HT2C on food intake behavior of rats.4,5

Biochem/physiol Actions

SB 242084 is a potent and selective antagonist of 5-HT2C receptor. It increases the basal activity of dopaminergic neurons and affects the behavioral responses mediated by 5-HT2C such as mesolimbic neuron activity and food intake.3,4,5

SB 242084 has a high affinity (pKi 9.0) for the cloned human 5-HT2C receptor and 100- and 158-fold selectivity over the closely related cloned human 5-HT2B and 5-HT2A subtypes respectively. SB 242084 had over 100-fold selectivity over a range of

Electrophysiological techniques and in vivo microdialysis were used to investigate the effect of SB 242084, a potent and selective 5-HT2C receptor antagonist in the control of nigro-striatal and mesolimbic dopaminergic function. Thus, extracellular single unit recordings were performed from neurochemically-identified

Rats consistently reduce their food intake following injections of bacterial lipopolysaccharides (LPS). Because inhibition of serotonergic (5-HT) activity by 8-OH-DPAT (5-HT(1A) activation) attenuates LPS-induced anorexia, we conducted a series of studies to examine whether other 5-HT-receptors are involved in the
6-Chloro-5-methyl-1-[[2-[(2-methyl-3-pyridyl)oxy]-5-pyridyl]carbamoyl]- indoline (SB-242084): the first selective and brain penetrant 5-HT2C receptor antagonist.

LPS, a potent activator of the innate immune system, is commonly used to investigate the acute phase response to infection, including anorexia. Serotonin 2C-receptor signaling has been shown to be involved in the mediation of LPS anorexia. Here we used
