 Use of PF-04995274


PF-04995274 is a potent, high-affinity, orally active and partial serotonin 4 receptor (5-HT4R) agonist. PF-04995274 has an EC50 range of 0.26-0.47 nM for human 5-HT4A/4B/4D/4E (Ki range of 0.15-0.46 nM), and has an EC50 range of 0.59-0.65 nM for rat 5-HT4S/4L/4E (Ki of 0.30 nM for rat 5-HT4S). PF-04995274 is brain penetrant and can be used to treat for cognitive disorders associated with Alzheimer's disease[1][2][3].

In Vivo PF-04995274 (3-10 mg/kg; intravenous injection; for 17 days; male 129S6/SvEv mice) treatment results in prophylactic efficacy by attenuating learned fear and decreasing stress-induced depressive-like behavior[1]. Animal Model: Male 129S6/SvEv mice (7-8 weeks) treated with contextual fear conditioning (CFC) and forced swim test (FST)[1] Dosage: 3 mg/kg, 10 mg/kg Administration: Intravenous injection; for 17 days Result: Attenuated learned fear and decreased stress-induced depressive-like behavior.
