Description
Curator's Comment: description was created based on several sources, including: http://www.eisai.com/news/news201464.html

Lorcaserin, currently marketed under the trade name Belviq and previously Lorqess during development, is a weight-loss drug developed by Arena Pharmaceuticals. Lorcaserin is a selective 5-HT2C receptor agonist, and in vitro testing of the drug showed reasonable selectivity for 5-HT2C over other related targets. 5-HT2C receptors are located almost exclusively in the brain, and can be found in the choroid plexus, cortex, hippocampus, cerebellum, amygdala, thalamus, and hypothalamus. The activation of 5-HT2C receptors in the hypothalamus is supposed to activate proopiomelanocortin (POMC) production and consequently promote weight loss through satiety. This hypothesis is supported by clinical trials and other studies. While it is generally thought that 5-HT2C receptors help to regulate appetite as well as mood, and endocrine secretion, the exact mechanism of appetite regulation is not yet known. Lorcaserin has shown 100x selectivity for 5-HT2C versus the closely related 5-HT2B receptor, and 17x selectivity over the 5-HT2A receptor

CNS Activity

Curator's Comment: Lorcaserin acts at 5-HT2C receptors in the central nervous system (CNS), particularly the hypothalamus, to reduce appetite

In Vitro Use Guide
Curator's Comment: Radioligand binding assays for human and rat 5-HT2A, 5-HT2B, and 5-HT2C receptors were developed using the 5-HT2 agonist [125I] DOI asadioligand.
Lorcaserin was evaluated for its ability to inhibit neurotransmitter uptake into rat brain synaptosomes. Lorcaserin weakly inhibited norepinephrine (EC50 = 2500 nM), serotonin (EC50 = 1400 nM), and dopamine (EC50 = 12,000 nM) uptake.
