Design, synthesis and evaluation of progesterone-adenine hybrids as bivalent inhibitors of P-glycoprotein-mediated multidrug efflux.
Steroidal bivalent ligands were designed on the basis of the described closer proximity of the ATP-site and the putative steroid-binding site of P-glycoprotein (ABCB1). The syntheses of seven progesterone-adenine hybrids were described. Their abilities to inhibit P-glycoprotein-mediated daunorubicin efflux in K562/R7 human leukemic cells overexpressing P-glycoprotein were evaluated versus progesterone.
