The in vitro transport of model thiodipeptide prodrugs designed to target the intestinal oligopeptide transporter, PepT1

A thiodipeptide carrier system is shown to be effective at enabling a range of covalently bound molecules, including benzyl, benzoyl and ibuprofen conjugates, to be transported via the intestinal peptide transporter PepT1, demonstrating its potential as a rational drug delivery target.
