Understanding Ligand Binding, Selectivity And Functions On The G Protein-Coupled Receptors: A Molecular Modeling Approach, Saheem Zaidi

Theses and Dissertations

The assessment of target protein molecular structure provides a distinct advantage in the rational drug design process. The increasing number of available G protein-coupled receptor crystal structures has enabled utilization of a varied number of computational approaches for understanding the ligand-receptor interactions, ligand selectivity and even receptor response upon ligand binding. The following dissertation examines the results from three different projects with varied objectives – i) structural modeling of human C-C chemokine receptor type 5 (CCR5) and assessment of the ligand binding pocket of the receptor, ii) assessment of the selectivity profile of naltrexone derivatives on the three opioid receptors …
