生物活性

Escitalopram ((S)-Citalopram) oxalate, the S-enantiomer of racemic Citalopram, is a selective serotonin reuptake inhibitor (SSRI) with a Ki of 0.89 nM. Escitalopram oxalate has ~30 fold higher binding affinity than its R(-)-enantiomer and shows selectivity over both dopamine transporter (DAT) and norepinephrine transporter (NET). Escitalopram oxalate is an antidepressant for the research of major depression[1][2].

IC50 & Target

Ki: 0.89 nM (serotonin transporter), 10500 nM (DAT), 8150 nM (NET)[1]

體內(nèi)研究
(In Vivo)

Escitalopram oxalate (10 mg/kg;腹腔注射;每日一次,持續(xù) 28 天) 改善應(yīng)激大鼠的認(rèn)知障礙并選擇性減弱磷酸化 tau 蛋白的積累[3]。
長(zhǎng)期服用 Escitalopram oxalate (每日一次;飲用水;總共 4 個(gè)月) 以 2.5 和 5 mg/d 的劑量分別顯著降低斑塊負(fù)荷 28% 和 34%[4]

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.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
