E6801 is a novel selective 5-HT6 receptor agonist with a wide range of biological activities.E6801 can be used in the study of dementia, Parkinson's disease, depression, obesity epilepsy, anxiety, and many other diseases.

E-6801 (1.25-10 mg/kg; i.p.) produced significant and mostly dose-dependent increases in novel object exploration, indicative of memory enhancement. Furthermore, sub-effective doses of E-6801 (1 mg/kg) when co-administered with either SB-271046 (3 mg/kg), donepezil (0.1 mg/kg), or memantine (5 mg/kg) significantly enhanced object-recognition memory. Additionally, using a 1-min inter-trial delay, E-6801 (2.5 and 5 mg/kg) was as effective as donepezil (0.3 and 1 mg/kg) in reversing a scopolamine-induced (0.5 mg/kg) impairment in object recognition. This study demonstrates that E-6801, a potent 5-HT(6) receptor agonist, improves recognition memory by combining cholinergic and glutamatergic neurotransmission modulation.[1]
