Description

XR9051 hydrochloride is an orally active and specific modulator of P-glycoprotein-mediated multidrug resistance (MDR)[1].

In Vitro

XR9051 is able to reverse resistance to a variety of cytotoxic drugs, including doxorubicin, etoposide and vincristine, which are associated with classical MDR[1].
XR9051 is highly active and gave at least a 15- to 20- fold decrease in the doxorubicin IC50, in the acquired resistance cell lines[1].

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

In Vivo

XR9051 (20-40 mg/kg, ip) shows significant modulatory activity in mice bearing MDR human ovarian (2780AD and CH1/DOXr) and SCLC (H69/LX) xenografts[2].

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

Animal Model: Female Balb/c mice (20-25 g)[2].
Dosage: I.V.
Administration: 20 mg/kg at various times (5 min to 24 h).
Result: The area under the concentration time curves (AUC) from time 0-∞ for plasma was 11.9 µg. h mL-1. The ratio between AUC for tissue:plasma for liver, heart and brain were 79.6, 16.9 and 0.3 respectively.
Animal Model: MDR 2780AD ovarian carcinoma xenografts[2].
Dosage: I.P.
Administration: 20, 30, 40 mg/kg daily with Epirubicin i.v. (10 mg/kg).
Result: Significantly reduced growth rate of MDR 2780AD ovarian carcinoma xenografts compared with either drug alone.

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.
