Circumventing P-glycoprotein-mediated cellular efflux of quinidine by prodrug derivatization.

Abstract

The objective of this study is to investigate whether transporter-targeted prodrug derivatization of quinidine, a model P-glycoprotein (P-gp) substrate, can circumvent P-gp-mediated efflux. The L-valine ester of quinidine (val-quinidine) was synthesized in our laboratory. Uptake and transport studies were carried out using the MDCKII-MDRI cell line at 37… (More)
