Abstract

Abstract: This contribution provides detailed insights regarding permeability properties of published cyclohexapeptides related to their conformation. The study includes data on oral bioavailability and PK parameters including application of a known enhancer. Interestingly, the latter did not show an effect, neither on the cyclic peptide exhibiting low oral uptake nor on the similar molecule showing a 30 % oral bioavailability in mice. These results are discussed in the context of exposed polar surface area for the preferred conformation and structural data obtained by NMR and X-ray crystallography.
