    Localization of NPs in H22 bearing tumor tissues. Mice bearing H22 tumors are intravenously injected with PLTM-HMnO2@Cur NPs and PSI-697 pre-treated (20 μg mL-1, 1 h) PLTM-HMnO2@Cur NPs. 24 h later, the tumors were removed and sectioned under frozen conditions followed by staining with an antibody against CD44 (green).

    PSI-697 is an oral P-selectin inhibitor with an IC50 of 125 μM[1].

    IC50 & Target

    IC50: 125 μM (P-selectin)[1]

    In Vitro

    PSI-697 inhibits the binding of a soluble human P-selectin to PSGL-1, in a reproducible concentration-dependent manner inhibiting 50% of binding at a concentration of 125 μM in vitro[1].

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

    In Vivo

    PSI-697 (0-50 mg/kg; p.o.) significantly reduces the number of rolling leukocytes by 39% versus vehicle control[1].
    PSI-697 (100 mg/kg; p.o.) reduces thrombus weight by 18% relative to vehicle, without prolonging bleeding time in a rat venous thrombosis model[1].
    PSI-697 (30 mg/kg; p.o.; daily; 6 days) promotes thrombus resolution and decreases inflammation in a baboon model of venous thrombosis[2].
    PSI-697 ((30 mg/kg; i.g.; daily) decreases vein wall injury in a rat stenosis model of venous thrombosis[2].

    Animal Model: 4-5 weeks male Sprague-Dawley rat (50-100 g)[1]
    Dosage: 0 mg/kg, 30 mg/kg, 50 mg/kg
    Administration: Oral administration
    Result: At an oral dose of 50 mg/kg reduced the number of rolling leukocytes by 39% versus vehicle control.

    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.
