Natural Products: From Discovery to Therapeutic Applications

Wednesday, March 18, 2020, 8:30 AM - 5:20 PM

The New York Academy of Sciences, 7 World Trade Center, 250 Greenwich St Fl 40, New York

Presented By

The Chemical Biology Discussion Group

The New York Academy of Sciences

 

Naturally occurring compounds have been used medicinally for centuries and continue to be a rich source of novel therapeutics, including antibiotics and cancer drugs. However, it is often challenging to determine the targets of these molecules and elucidate their mechanisms of action. Moreover, detailed understanding of the complex chemistry underlying the biosynthesis of these compounds is critical for functional studies as well as to derive optimized drugs. This one day symposium will discuss the latest research in natural products with a focus on their discovery, mechanisms of action and therapeutic applications across a wide range of disease indications.

Keynote Address: Chasing Molecules and Mechanisms in the Gut Microbiome

Speaker

Jon Clardy, PhD
Harvard Medical School

Numerous studies with varying degrees of statistical power have found correlations between the composition of the bacterial population in the human gut microbiome and disease states. But the molecules and mechanism(s) connecting a dysbiotic microbiome to a specific disease are generally unknown. In an attempt to address this gap, we undertook a series of screens to link bacterial metabolites with diseases like type 1 diabetes (T1D) and inflammatory bowel disease (IBD). We focused on primary drivers of inflammation like TNFα (tumor necrosis factor alpha) produced by dendritic cells. The talk will describe our screening logic, the selection of candidate bacterial strains, the discovery of the small molecule regulators of cytokine production, their structures and biosynthesis, and inflammatory mechanism.

Discovery and Engineering of Plant Chemistry for Plant and Human Health

Speaker

Elizabeth Sattley, PhD
Stanford University

Plants are some of the best chemists on the planet and produce an impressive array of small molecules. We are inspired by the fact that humans have become extraordinarily reliant on plant-derived molecules for food, medicine, and energy. However, remarkably little is known about how plants make these molecules, limiting our ability to engineer and optimize plant metabolic pathways. New plant genome sequences and synthetic biology tools have enabled three research areas under investigation in my lab: 1) Identifying the minimum set of enzymes required to make known plant-derived molecules and non-natural derivatives through metabolic engineering, and 2) discovering new molecules from plants, and 3) developing new strategies to enhance plant fitness. In this talk, I will describe some of our recent efforts to accelerate the discovery of complete plant pathways for known and novel molecules, not only in the model plant Arabidopsis but also in non-model plants.

Reimagining Druggability Using Chemoproteomic Platforms

Speaker

Dan Nomura, PhD
University of California, Berkeley

The Nomura Research Group is focused on redefining druggability using chemoproteomic platforms to develop transformative medicines. One of the greatest challenges that we face in discovering new disease therapies is that most proteins are considered “undruggable,” in that most proteins do not possess known binding pockets or “druggable hotspots” that small-molecules can bind to modulate protein function. Our research group addresses this challenge by advancing and applying chemoproteomic platforms to discover and pharmacologically target unique and novel druggable hotspots for disease therapy. We currently have three major research directions. Our first major focus is on developing and applying chemoproteomics-enabled covalent ligand discovery approaches to rapidly discover small-molecule therapeutic leads that target unique and novel druggable hotspots for undruggable protein targets and pathways. Our second research area focuses on discovering and exploiting unique druggable modalities accessed by natural products. Our third research area focuses on using chemoproteomics-enabled covalent ligand discovery platforms to expand the scope of targeted protein degradation and to discover new induced proximity-based therapeutic modalities.Collectively, our lab is focused on developing next-generation transformative medicines through pioneering innovative chemical technologies to overcome challenges in drug discovery.

Mighty Chemistry of Bacterial Small Molecules as Antibiotics

Speaker

Bo Li, PhD
University of North Carolina at Chapel Hill

Bacteria produce many small molecules that possess unique structures and potent antimicrobialactivity. It is often unclear how these molecules impart their activity. I will discuss our work on understanding the mode of action for the broad-spectrum, dithiolopyrrolone antibiotics. We showed that this family of natural products inhibits metal-dependent enzymes in cells via metal-ion chelation. The cyclic ene-disulfide of the dithiolopyrrolone exhibits unusual redox chemistry and is essential for activity. I will also describe our efforts on elucidating the mode of action of the natural product thiomarinol A. Thiomarinol A is a hybrid antibiotic that combines the dithiolopyrrolone and a close analog of mupirocin, the latter of which is used to treat methicillin-resistant Staphylococcus aureus. Our work identified novel antimicrobial mechanisms and could help discover and design antibiotics that can avoid or overcome resistance.
