←Within this dissertation the topic of virtual screening is discussed with regard to three different cancer targets and also a brief introduction of the tools used in virtual screening. In Chapter 1, the reader will be introduced to virtual screening and the programs that are used in virtual screening. In Chapter 2, the first of three projects are discussed. This project consists of the work that was done to find inhibitors of the P53 binding domain of MDMX. In this project the mobility of residues within the binding site of MDMX are discussed and the ways in which we attempted to model how drugs would bind two adjacent pockets within MDMX. In Chapter 3, the virtual screening and modeling work done for RING domain of MDM2 and MDMX is discussed. This work was done in conjunction with Moffitt Cancer Center in order to solve the 60 year old mystery of the mechanism of how thalidomide and possibly its analog lenalidomide caused children to be born limbless. Current thinking is that Cereblon through an unknown teratogenic mechanism activates an increase in FGF8. We suggest a mechanism that may happen in parallel that involves stabilization of MDM2 and the reduction of P63 levels. Chapter 4, the work that was done against the BH3 binding domain of MCL-1 is discussed in conjunction with collaboration with the Manetsch lab. In order to complete this screening the validation of IC50 values and then attempt to modify those products based upon the structure of MCL-1. Chapter 5 discusses the work done to find inhibitors of deoxycytidine kinase. All of these chapters taken together provide a brief overview of the computational work done produce inhibitors of Protein-Protein Interaction against three major cancer targets.
