Description

W146 is a selective antagonist of sphingosine-1-phosphate receptor 1 (S1PR1) with an EC50 value of 398 nM.

IC50 & Target

EC50: 398 nM (S1PR1)[1].

In Vitro

W146 is a S1PR1 antagonist with a Ki of ~70-80 nM[1].
W146 pretreatment significantly increases activated cleaved caspase-3 levels. The reduced EPCs apoptosis which induced by S1P is completely abolished after treatment with W146[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Apoptosis Analysis[2]

Cell Line: Endothelial progenitor cells (EPCs).
Concentration: 10 μM.
Incubation Time: 30 min before the addition of S1P.
Result: Increases activated cleaved caspase-3 levels.
In Vivo

W146 (5 mg/kg, ip, prior to AMD3100 administration) pre-treatment shows approximately 8-fold increase of KSL-HSPC mobilization, measured by the CFU-G/M colony forming assays, compared to that in mice treated with AMD3100 alone[3]
The W146-mediated augmentation of KSL-HSPC mobilization is specific, because pretreatment of mice with W140 is unable to produce any effect on AMD3100-stimulated KSL-HSPC mobilization. Injections of W146, W140, JTE013, or Cay10444 do not alter the basal WBC count in mice[3].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Mice (4-6-week-old)[3]
.
Dosage: 5 mg/kg.
Administration: IP, 1 hour prior to AMD3100 (ADM) administration.
Result: Significantly increased in KSL-HSPC mobilization compared to that in mice pretreated with dextran followed by AMD3100 administration.

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.
