Application

Valspodar/ PSC-833 has been used as a ABCB1 (P-glycoprotein) inhibitor.

Biochem/physiol Actions

Valspodar is a nonimmunosuppressive cyclosporin analog and potent P-glycoprotein (MDR1) inhibitor. Valspodar reverses multidrug resistance (MDR) by inhibiting cellular drug efflux mediated by P-glycoprotein.

The aim of this study was to assess the potential of polymeric micelles to solubilize valspodar and modify its pharmacokinetics following intravenous and oral administration in rat. Drug-loaded methoxy poly(ethylene oxide)-b-poly(epsilon-caprolactone) (PEO-b-PCL) micellar solutions were prepared and administered either intravenously

Valspodar, a non-immunosuppressive analog of cylosporine, is a potent P-glycoprotein (MDR1) inhibitor. As MDR1-mediated efflux of chemotherapeutic agents from leukemic blasts may contribute to drug resistance, a phase 1 study of valspodar combined with mitoxantrone and etoposide in pediatric patients

Stem cells of normal tissues have resistance mechanisms that allow them to survive genotoxic insults. The stem cell-like cells of tumors are defined by their tumor-initiating capacity and may have retained these resistance mechanisms, making them resistant to chemotherapy. We
