Design, synthesis and evaluation of progesterone-adenine hybrids as bivalent inhibitors of P-glycoprotein-mediated multidrug efflux

Bioorg Med Chem Lett. 2010 May 15;20(10):3165-8. doi: 10.1016/j.bmcl.2010.03.085. Epub 2010 Mar 28.

Abstract

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.
