Improving our mechanistic knowledge of the influence of specific molecular descriptors of bRo5 drugs on oral absorption
Details
- Funder: Vinnova
Research scientist: Prosper Emeh, MSc.
Principal investigator: Professor Christel Bergström, Department of Pharmacy, Uppsala University.
Scientific and industrial context: The oral delivery of macromolecular drugs, beyond Lipinski’s Rule of 5 chemical space, such as peptides, proteins, and oligonucleotides, even when co-administered with transient permeation enhancers (TPEs), still presents the problem of a low (single digit) and variable bioavailability.

Aim: The project aims to study the physicochemical characteristics of beyond-the-rule-of-5 (bRo5) drugs and TPEs, explaining their interaction and the interplay with gastrointestinal barriers to improving oral bioavailability.
Outcome: We expect to improve our mechanistic knowledge of the influence of specific molecular descriptors of bRo5 drugs on oral absorption. The generated data could provide more insight into the macromolecule/permeation enhancer axis, possibly enabling a rational selection of TPEs while considering the physical-chemical properties of the orally administered macromolecule.
