Biological Activity

[Description]:

Ro 04-6790 is a potent, competitive and selective 5-HT6 receptor antagonist with pKi values of 7.26, 7.35 for rat and human 5-HT6 receptors, respectively. Ro 04-6790 has no affinity at other receptors[1].

[Related Catalog]:

Research Areas >> Neurological Disease

Signaling Pathways >> GPCR/G Protein >> 5-HT Receptor

Signaling Pathways >> Neuronal Signaling >> 5-HT Receptor

[Target]

Rat 5-HT6 Receptor:7.26 (pKi)

Human 5-HT6 Receptor:7.35 (pKi)

[In Vitro]

Ro 04-6790 has over 100 fold selective for the 5-HT6 receptor compared to other receptor binding sites (IC50>10 μM)[1].

[In Vivo]

Ro 04-6790 (10 mg/kg, SC) produces a modest (50%) increase in ACh outflow in adult male Wistar rats of 250-300 g (this effect is not statistically different from the action of vehicle)[2].
