Full development drug interactions

At one stage in the development of modern kinetic understanding it was believed that displacement of one drug from its binding site on plasma proteins by another with greater affinity was a common interaction which explained many clinical events. Much of this belief came from experiments in the laboratory where it was easy to demonstrate such displacement. Unfortunately, isolated solutions of plasma proteins do not tell the full story, for, in the body, a rising free fraction of a drug is usually matched by enhanced clearance and the re-establishment of a new steady state. 

NMR spectroscopy is a powerful tool for chemistry and structural biology, especially when NMR is applied to study protein-ligand interactions. In the drug discovery process, NMR is used to study whether a compound binds to a protein up to the determination of the full three-dimensional structure of the complex.Rational drug discovery requires an early appraisal of all factors impacting on the likely success of a drug candidate in the subsequent preclinical, clinical and commercial phases of dug development. Tlie study of absorption, distribution, metabohsm and excretion/pharmacokinetics (ADME/PK) has de-...
