Daniel Adu-Ampratwum, PhD

Research Assistant Professor

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.

Xiaolin Cheng, PhD

Professor

Dr. Cheng’s laboratory aims to develop an interdisciplinary research program centered on Computer Aided Drug Design and Discovery. Closely collaborating with experimental chemists and biologists, our group utilizes a myriad of computational modeling & simulation, and data analytics techniques to understand molecular basis of drug action and to rationally design new drug molecules. Our group also has long-standing interests in: a) developing and applying multiscale computational techniques to investigate the structure, dynamics and function of complex biomolecular (and cellular ) systems; and b) bridge large-scale molecular simulation with systems biology (cellular metabolism and signaling networks) towards a new drug discovery paradigm.

James Fuchs

Associate Dean for Research and Graduate Studies

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.

Kou-San Ju, PhD

Associate Professor

My interdisciplinary research program is inspired by the metabolic diversity of microorganisms and the vast array of compounds they produce. Working at the interface of chemistry and biology, my group combines approaches in chemistry, biochemistry, bioinformatics, genetics, and systems biology to discover new natural products, identify bioactivity and mode of action, and to decipher the metabolic basis of their biosynthesis. Ultimately, we seek to translate insights gained from our investigations into solutions for modern day challenges facing human health and the environment. These include new antibiotics to counter drug-resistant pathogens, novel herbicides and biocontrol agents to improve pest management and food security, and engineered biocatalysts to facilitate chemical production by green chemistry and industrial biotechnology.

Kwangwoon “Jon” Lee, PhD

Assistant Professor

The Chromatin Design Lab develops engineered proteins and biosensors to study chromatin regulation and transcriptional control. We aim to create custom molecular tools, including mutant-selective binders and sensors that recognize specific combinations of post-translational modifications. These approaches will be used to investigate how histone modifications and transcription factors regulate gene expression, and to design new strategies for targeting diseased epigenetic regulation.

Pui Kai (Tom) Li, PhD

Associate Professor

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.

Blake R. Peterson, PhD

Chair of the Division of Medicinal Chemistry & Pharmacognosy

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.

Liva Rakotondraibe, PhD

Associate Professor

New natural product sources (new and unidentified fungal and bacterial microorganisms, microbial endophytes, new endemic and medicinal plant species, etc.) contain many undiscovered potential bioactive secondary metabolites that can be used to combat world’s deadly diseases including cancer, malaria, viral infections, and chemoresistance. Their investigation must be prioritized in order to discover new pharmacophores for potential drug candidates. My lab focuses on (1) bioassay-guided isolation, structural elucidation and development of bioactive compounds from natural sources, (2) Drug discovery from Madagascan natural products and (3) drug discovery from ethnomedicine. One of our recent ongoing projects is on the development of insecticides that can be used to control mosquito vector of Zika virus from Madagascan endemic plants.
