Descrizione Rational drug design involves prediction of the selectivity and specificity of drug-protein interactions. Numerous (over 20) atomic resolution structures of FABP exist in the Protein Data Bank (PDB) but they are from different FABPs and animal sources and hence must be refined for human FABP12 through homology modeling based on the existing crystal structure scaffolds. Molecular dynamics will be used to model multiple equilibrated states of the solvated proteins representing their range of flexibility in solution. We will accurately characterize protein-protein and protein-drug interactions, and perform binding free energy analysis using the MM/PBSA method. We will then generate chemical structures in silico (with the Molecular Operating Environment and/or the Schrodinger Drug Discovery software) to create synthetically accessible compounds. Ligand preparation software will generate representative 3D structures and their tautomeric and stereochemical variants, which will be filtered for PK or toxic liabilities using ADME prediction software estimates. We will apply consensus docking methodology (with e.g. AutoDock, Vina, DOCK, etc.) for the target protein and all compounds, ranking them based on their target protein affinity and accounting for molecular weight, lipophilicity, chemical tractability, cell membrane permeability, and patentability. This task will utilize cheminformatics, combinatorial chemistry and molecular modeling.
The student will be able to perform the tasks for the project in collaboration with researchers at the University of Alberta in Edmonton, Canada.
