Escitalopram
Based on 11 publication(s) in Google Scholar
Escitalopram ((S)-Citalopram), the S-enantiomer of racemic Citalopram, is a selective serotonin reuptake inhibitor (SSRI) with a Ki of 0.89 nM. Escitalopram has ∼30 fold higher binding affinity than its R(-)-enantiomer and shows selectivity over both dopamine transporter (DAT) and norepinephrine transporter (NET). Escitalopram is an antidepressant for the research of major depression.

Chronic administration of Escitalopram (daily; drinking water for a total of 4 months) significantly reduces plaque load by 28% and 34% at 2.5 and 5 mg/d, respectively [4].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Male Sprague-Dawley rats[3]
-
Dosage:10 mg/kg
-
Administration:I.p.; daily for 28 days
-
Result:Could selectively decrease phosphorylated tau accumulation in the hippocampus of stressed rats and could distinctly alleviate the hyperactivity of the HPA axis in both depressive and resistant rats.
-
Animal Model:APP-PS1 hemizygous female mice (4 months of age)[4]
-
Dosage:2.5-5 mg/kg
-
Administration:Daily; drinking water for a total of 4 months
-
Result:At both doses significantly reduced plaque burden within the brains of these mice compared to littermate controls that drank only water. Hippocampal plaque load was significantly reduced by 28.7% and 34.4 % for ESC 2.5 mg/day and 5 mg/day, respectively.
