Chemical Synthesis

Many organic small molecules serve as drug leads for drug discovery and drug development programs. Understanding the structure and mechanism of action of these small molecules is essential for drug lead optimization. Also having a reliable synthetic access to these organic small molecules is important to aid in SAR studies and lead optimization in the search for new drugs for various diseases. Dr. Adu-Ampratwum's area of interest includes exploring novel synthetic methods for the synthesis of small organic molecules as lead compounds for drug discovery. His current research area focuses on designing and synthesizing small molecules to study HIV and cancer biology and as potential therapeutics.

Dr. Antwi's expertise includes the design and synthesis of bioactive molecules for various diseases such as HIV-AIDs, cancer, and neglected tropical diseases. She teaches chemistry-related courses, including biochemistry and medicinal chemistry. She uses active learning techniques and promotes an environment where all students can be successful inside and outside the classroom.

The research in Dr. Fuchs' lab focuses on the design and preparation of bioactive molecules for therapeutic applications against cancer and infectious diseases. His lab utilizes fundamental chemical knowledge and synthetic methodology to facilitate the process of drug discovery and development through the generation of biological probe molecules, the synthesis and modification of lead compounds, and the optimization of drug properties. The overarching goals of these studies are to understand the mechanisms through which small molecules interact with proteins or other biomolecules in the context of disease progression and to improve the potential utility of promising new compounds to help them advance toward the clinic. Recently, the Fuchs lab has collaborated with numerous labs in the areas of natural product drug development for various cancers, the preparation of protein degraders active against leukemia, and HIV-1 capsid and integrase drug development.

Dr. Guo works on both basic research and its subsequent practical applications, focusing on understanding the mechanisms and assembly of viral DNA packaging motor, and using components of the biomotor for various applications. By applying interdisciplinary approaches including chemistry, biophysics, biochemistry, nanotechnology, bioengineering, molecular biology, cell biology, computer modeling, and pharmaceutical sciences, Dr. Guo studies RNA, DNA and proteins and their interaction.

Dr. Guo’s current project areas are:

RNA nanotechnology and its application for the delivery of siRNA/miRNA/drug for the treatment of cancers, viral infection, and genetic diseases
Nanobiotechnology, including structure, function and mechanism of Phi29 DNA-packaging nanomotor
Single molecule imaging and optical instrumentation to study the interaction of RNA, DNA, and protein
Single pore technology for DNA sequencing, macromolecule detection, and disease diagnosis, using channels of variety of viral DNA packaging motors

Dr. Li’s research interest focuses on the design, syntheses and studies of small molecules for cancers and infectious diseases. In the cancer area, our group focus on prostate and pancreatic cancer. Novel molecules are developed using the strategies of drug repurposing and structure-based drug design (in collaboration with Dr. Xiaolin Cheng). In the research of infectious disease, our focus is on the development of small molecules for the treatment of COVID-19. Novel molecules are generated through computational chemistry, molecular modeling and virtual screening targeting the interface of spike protein and human ACE-2 receptor.

Dr. Peterson’s research group works to design, synthesize, and discover small molecules that affect the proliferation of cancer cells and associated immune cells that support malignancy. To identify these compounds, the Peterson laboratory synthesizes fluorescent molecular probes as tools for drug discovery. These probes are used to create target-based or phenotypic drug discovery assays to identify anticancer agents with novel mechanisms of action. To optimize and evaluate these compounds, they use synthetic organic chemistry, medicinal chemistry, and chemical biology approaches. In conjunction with high throughput screening by confocal microscopy, flow cytometry, and other related techniques, his laboratory identifies chemical probes of biological systems, uncovers mechanisms of biologically active agents, and discovers hit and lead compounds for the development of therapeutics.
