Application Of Linear Free Energy Relationships In The Prediction Of Triglyceride/Water Partition Coefficients And Lipid Bilayer Permeability Coefficients Of Small Organic Molecules And Peptides, Yichen Cao
University of Kentucky Doctoral Dissertations
Computational methods such as linear free energy relationships (LFERs) offer a useful high-throughput solution to quickly evaluate drug developability, e.g. membrane permeability, organic solvent/water partition coefficients, and solubility. LFERs typically assume the contribution of structural components/functional groups to the overall properties of a given molecule to be constant and independent. This dissertation describes a series of studies in which linear free energy relationships were developed to predict solvation of small organic molecules in lipid formulations, specifically, triglyceride containing solvents and phospholipid-based liposomes. The formation of intermolecular HBs in triglyceride solvents (homogenous with H-bond accepting ability) and intramolecular HBs within the …
