Aurora B ve cSrc kinazlara özgü inhibitör moleküllerin bulunması

Many cancers have been associated with the deregulation of kinases that have become a prime target for cancer treatment. In this project, we aim to determine Aurora B kinase specific and cSrc kinase specific inhibitors by conducting virtual screening on ZINC database molecules. In our first project, our vision includes different binding site of drugs for the inhibition of Aurora B that have not yet been taken into account in previous reported studies. Indeed not only we aim to find the compounds that inhibit Aurora B but we also want to find drugs that are specific to Aurora B. Those molecules, which are theoretically shown to act as good inhibitors, are also verified experimentally. Promising results are obtained which display that our inhibitors cause reduction in Aurora B activity. As a second project, we identify cSrc specific inhibitors theoretically. The molecules found for cSrc are bound in the ATP pocket and extended into the allosteric site in the inactive conformation of the cSrc kinase. They are bound in conserved ATP pocket by hydrophobic interactions and resided in the allosteric site by making direct hydrogen bonds with residue GLU310. The binding mode of these inhibitors is the same as of type II kinase inhibitors. They bind to less conserved allosteric site and conserved ATP pocket simultaneously.
