1. Computational and Experimental Models for the Prediction of Intestinal Drug Solubility and Absorption
Sammanfattning : New effective experimental techniques in medicinal chemistry and pharmacology have resulted in a vast increase in the number of pharmacologically interesting compounds. However, the number of new drugs undergoing clinical trial has not augmented at the same pace, which in part has been attributed to poor absorption of the compounds. LÄS MER
2. ATP-Binding-Cassette Transporters in Biliary Efflux and Drug-Induced Liver Injury
Sammanfattning : Membrane transport proteins are known to influence the absorption, distribution, metabolism, excretion and toxicity (ADMET) of drugs. At the onset of this thesis work, only a few structure-activity models, in general describing P-glycoprotein (Pgp/ABCB1) interactions, were developed using small datasets with little structural diversity.

3. Experimental and Computational Predictions of Drug Solubility in Human Gastrointestinal Fluids
Sammanfattning : The aqueous solubility of a drug is viewed as a pivotal property for its oral absorption since only dissolved molecules can permeate the gut wall and reach the systemic circulation. The fluids in the intestine, however, do not only consist of water and therefore poor water solubility may not necessarily imply a poor solubility in the intestinal fluids and resulting low bioavailability.

4. Insights into the small intestinal colloids and their impact on drug solubility
Sammanfattning : Oral administration is the preferred route for drug delivery because it has high patient compliance and is cost effective. The aqueous solubility of modern drug candidates is often poor, but a drug delivered orally must dissolve in the intestine so that it can be absorbed into the circulation. LÄS MER
5. Predicting oral performance of lipid-based formulations using in vitro methods
Sammanfattning : Oral administration of drugs is widely considered preferable to other methods by end-users and healthcare providers alike; however, not all drug compounds are inherently suited for it because some molecules are not well-absorbed by the intestine. Good absorption requires both dissolution and permeation. LÄS MER
