Key Points

This research aims to improve the oral bioavailability of a CK2 inhibitor through the use of amino acid prodrugs.
Investigated dose proportionality and pharmacokinetics of the CK2 inhibitor in a controlled trial.
Utilized portal vein cannulation to assess intestinal first-pass bioconversion of prodrugs.
Analyzed systemic exposure levels of the prodrug compared to standard administration.
Achieved a 64.6% improvement in dose proportionality.
Demonstrated that the prodrug undergoes significant intestinal first-pass bioconversion, leading to minimal systemic exposure.
Positioned amino acid prodrugs as effective for enhancing oral bioavailability of drugs with poor solubility.

Implication

Explores amino acid prodrugs to overcome poor solubility in drug delivery, suggesting a new method for improving medication effectiveness.

Abstract

= 64.6%) with improved dose proportionality. Mechanistic investigation via portal vein cannulation revealed predominant intestinal first-pass bioconversion, explaining the minimal systemic prodrug exposure. These findings position amino acid prodrugs as a practical, low-risk strategy for unlocking oral bioavailability of dissolution-limited kinase inhibitors, offering broad applicability in contemporary drug discovery and development.
