Optical Properties and Molecular Modeling of Cyclic Dipeptides

Background: Most drugs in use today were discovered empirically. Lead compounds were generated by screening large numbers of synthetic or natural products for a desirable effect in some test system. The test system might, or might not, be a good model for the human illness under study.

Once a lead compound has been identified, its activity can be improved and its side effects reduced through systematic molecular modifications. The entire process, however, is largely trial and error.

The modern approach to studying human illness, based on molecular biology, identifies the origins of clinical observations at the molecular level. For example, the three-dimensional structure of an enzyme and its active site, perhaps vital to viral replication, is identified. A drug which can block this active site can be rationally designed. Viral replication is stopped. This is where computers, via molecular modeling, become useful.

Molecular modeling is the process of predicting three-dimensional structure and other chemical properties of molecules using computational methods. All molecular modeling methods require the use of data derived from experimental measurements on known molecules. A mathematical format for generalizing this experimental data allows measurements from known systems to be extended to unknown systems.

How reliable is the modeling software in cases where a high degree of accuracy is essential? Through the use of circular dichroism (CD) spectroscopy, an experimental technique to determine the conformation of molecules in solution, and cyclic dipeptides, which serve as model compounds, I was able to shed some light on this question.
