Dr. Guida's research is focused on computer aided drug design. An area of specific interest to the Guida Lab is the design of inhibitors of enzymes essential for the biosynthesis of polyamines, which are critical for the replication of DNA and are elevated in a number of human tumors. This work has focused on the design of S-adenosylmethionine decarboxylase inhibitors as potential anti-cancer agents and involves a collaboration with Professor Steve Ealick (Cornell University), Professors Anthony Pegg and Diane McCloskey (Hershey Medical Center at Penn State University) and Drs. Jack Secrist and Bill Waud (Southern Research Institute). Through collaboration with investigators at the Moffitt Cancer Center & Research Institute, Dr. Guida has also been involved in the computational design of inhibitors of other enzymes and inhibitors of protein-protein interactions that have therapeutic relevance in cancer. This work includes the following biomolecular targets: farnesyl transferase and geranylgeranyl transferase (in collaboration with Drs. Said Sebti and Nick Lawrence), the 20S Proteasome (with Drs. Said Sebti and Mark McLaughlin), MDM2-p53 and MDMX-p53 (with Drs. Jian-dong Chen and Mark McLaughlin) and Shp2 (with Drs. Jerry Wu and Nick Lawrence). Dr. Guida's lab has also been interested in developing enhanced methods for the docking of inhibitors into protein binding sites in which induced fit effects are important and in applying computational techniques to the problem of elucidating the mechanistic details of enzyme catalysis. Dr. Guida also has an interest in the design, synthesis, and study of model complexes that mimic zinc metalloproteases.
