Abstract excerpt
Multidrug resistance (MDR) is a widely studied mechanism of cellular resistance to structurally unrelated cytotoxic agents. The MDR phenotype is related to the overexpression of the MDR1 gene product, P-glycoprotein (P-gp), a transmembrane drug efflux pump. The capacity to compete with the cytotoxic drug for the active outward transport process, thus inhibiting the activity of the P-gp pump, has been demonstrated...
