William L. Scott Ph.D.
Dr. Scott has extensive experience in both the pharmaceutical and academic environments. He is building on this experience through a project called Distributed Drug Discovery (D3) which is being developed at IUPUI in collaboration with Dr. Marty O'Donnell. At the center of this project is the belief that student learning is more effective when students clearly see the direct application of acquired knowledge to an important challenge.
Distributed Drug Discovery provides this organizing and motivating context as we teach the theory and practice of organic, computational and biological chemistry, and students apply one or more of these skills to the search for drug leads for neglected diseases. D3 proposes that if simple, inexpensive equipment and procedures are developed for each of the core disciplines of drug lead discovery - computational chemistry, synthetic chemistry, and biological characterization - a large problem can be divided into manageable smaller units and carried out by students, in parallel, at multiple academic sites throughout the world. The coordinated and recombined results of these distributed resources can accelerate the identification of leads in the early stages of the drug discovery process. Simultaneously, this effort provides educational opportunities in both the developed and developing worlds, while building cultural bridges for the common good.
D3 creates an opportunity for students to learn synthetic organic chemistry, computational chemistry and biology in a setting that incorporates key elements of the research environment normally absent in traditional lab courses. It engages beginning students with a research challenge that is scientifically important and socially relevant. A small subset of these students may choose to pursue scientific research and become actively involved with faculty in the development of future undergraduate laboratories. Some of them go further to teach (as teaching assistants in the undergraduate lab), relaying their in-depth expertise to their peers and serving as role models. Because drug discovery is the premier example of a challenge requiring integrated scientific expertise, students participating in these contextualized laboratories, whatever their ultimate role in society, will come away with a deeper understanding and appreciation of the integral place science plays in their lives.
D3 requires powerful yet student accessible tools to permit them to learn and participate in a meaningful way in all aspects of drug lead discovery. We want them to learn skills that can have a direct and major impact. This is a key challenge for the program. All the disciplines required of D3 share this same imperative. Our synthetic chemistry component is most developed. It has been implemented at sites in Russia, Spain and Poland, along with a number of academic institutions in the United States.
The focus of Dr. Scott’s basic research is the development of simple and inexpensive equipment and combinatorial synthetic methodologies to quickly make large numbers of “drug-like” molecules that facilitate the Distributed Drug Discovery project. These compounds can be screened in biological assays to generate leads for drug discovery. His synthetic focus is on the solid-phase synthesis of conformationally constrained peptidomimetic molecules, other general classes of biomimetic molecules, and unnatural amino acids.
