Broadly speaking, medicinal chemistry involves applying chemical and molecular approaches applied for the purpose of drug discovery. Given the multidisciplinary nature of medicinal chemistry, the College of Pharmacy conceptualizes medicinal chemistry as consisting of four specialized areas of research:  biochemistry, biophysics, bioinformatics, and organic chemistry.  (Our curriculum for the Medicinal Chemistry PhD program is organized around these four areas.  See Curriculum)

Our faculty's research programs are varied, but many share a common focus on elucidating molecular processes involved in ligand interactions with macromolecules, mechanisms of enzyme catalysis, and signal transduction. 
Research groups use both chemical and biochemical techniques to:

  • Design and synthesize organic molecules as probes
  • Determine steady-state and pre-steady-state kinetics to characterize enzyme-catalyzed reactions and interactions of enzymes and receptors with various ligands
  • Investigate biological structure and function by the generation and characterization of mutant macromolecules using molecular, biological, kinetic, and structural (nuclear magnetic resonance and crystallographic) approaches

Once active compounds have been discovered, major research efforts are dedicated to understanding the molecular basis for the modes of action of new compounds.

Students interested in the biochemical aspects of drug design and action can carry out research on some of the most exciting topics in contemporary biology while obtaining excellent training in a rigorous, chemistry-based program.

Biophysics is the application of physical techniques to biological systems. These approaches can be experimental or theoretical. Many of the faculty use nuclear magnetic resonance (NMR) data and X-ray crystallography to gain structural insights into protein-ligand interactions. These data are used to explain the effects of mutagenesis and to direct structure-based drug design. Several labs use spectroscopy of small molecules to gain insights into biological systems. These data can elucidate the conformation of ligand molecules, and analyzing NMR data for labeled substrates/products can explain cryptic mechanisms of pharmacologically relevant proteins.

Computational chemistry, statistical mechanics, and molecular modeling can clarify complex biological data. These techniques are central to computer-aided drug discovery and protein folding prediction. Models of protein-ligand interactions can unlock the biophysical patterns that govern molecular recognition. Key issues include: ligand docking, scoring functions, protein flexibility, protein folding, and the predictive power of the resulting models.

  • Shaomeng Wang (protein simulations, protein-ligand interactions, binding free-energy predictions, and structure-based drug discovery) Lab

Computers run much of our laboratory equipment, store huge databases of genomic and chemical information, and model drugs interacting with biological receptors at the molecular level.  Experts in this field work with computers to develop complex statistical or physical models and validate them against large sets of experimental results.  Many faculty develop mathematical models to analyze physical and biological assay data, and to gain insights into drug mechanisms of action, protein-ligand interactions and ADME-Tox properties.

The large size of the datasets and the programming-intensive techniques for data mining are what set bioinformatics apart from the more theoretical biophysical studies. Bioinformatic studies at the College of Pharmacy focus heavily on research insights, database development, and new mining techniques. The College does not offer masters-level studies for academic librarians.

Faculty investigate a wide variety of challenging problems in synthetic organic chemistry. A common focus is the use of modern synthetic methods to prepare complex organic molecules for use in the study of a number of important biological problems. Students receive excellent training in organic synthesis while learning the biochemical aspects of drug design and evaluation.

For example, the design, synthesis, and biological evaluation of artificial activators of gene expression are an ongoing efforts, as is the stereoselective synthesis of beta-amino acids for a variety of biochemical and synthetic applications. The discovery/development of new transition metal-catalyzed reactions and new synthetic methods for use in the synthesis of complex molecules is also an active area of research. Modern methods of heterocyclic synthesis are being used to make complex drug-like molecules for inhibiting novel targets in infectious diseases and cancer. A more recent effort involves "hit to lead" campaigns, in which a small molecule inhibitor derived from screening against a biological target is optimized synthetically into a drug-like molecule by developing structure-activity relationships (SAR). The design and synthesis of radiopharmaceuticals is an area of research that is rarely found in medicinal chemistry departments.
