Last updated

Amanda E. Hargrove is a chemist and professor at Duke University (Durham, North Carolina, United States). Hargrove is also the editor-in-chief of Medicinal Research Reviews , [1] and a member of the Scientific Advisory Board of Arrakis Therapeutics. [2] At Duke University, Hargrove directs an interdisciplinary research program in chemical biology that focuses on harnessing the specific interactions between small molecules and RNA, and using those RNA-small molecule interactions to probe the structure, and function of RNA. The long-term goal of the group's research is to identify specific molecule-RNA interactions that may have therapeutic potential in the treatment of viral infection and human disease. She has received numerous awards for her scientific research, teaching, and service in support of diversity, equity, and inclusion.

Academic career

Hargrove attended Trinity University in San Antonio, Texas and received her B.S. in Chemistry and Spanish in 2004. [3] As an undergraduate student, she conducted research with John D. Spence on the synthesis and Bergman cyclization of meso-tethered enediyne-porphyrins. [4] Hargrove conducted her graduate work with Professors Eric V. Anslyn and Jonathan L. Sessler at the University of Texas, Austin, and earned her Ph.D. in 2010 for her thesis, Combining recognition motifs for improved sensing and biological activity of oligosaccharides and phosphorylated molecules. [5] From 2010 to 2013 she was an NIH Postdoctoral Fellow in Chemistry at California Institute of Technology, where she worked in the lab of Peter B. Dervan [6] and conducted research on DNA-binding polyamides as inhibitors of a prostate-specific response gene in prostate cancer. [7] Her postdoctoral work also focused on optimizing conditions to increase solubility of pyrrole-imidazole polyamide DNA-binding molecules as a strategy to increase their biological activity (these are a class of potential DNA-targeting therapeutics). [8] Hargrove became assistant professor in the department of chemistry at Duke University in Durham, NC in 2013 and earned promotion to associate professor with tenure in 2020. [9] [10]

Research

Hargrove's research program focuses on organic chemical synthesis and screening of small molecules that have specific interactions with different RNA structural motifs. The aim of the research is to identify small molecules that can target the specific RNA structures found in viruses. Hargrove's research program has identified RNA-binding molecules that can inhibit replication of Sars-CoV-2 virus [11] and enterovirus (the virus that causes hand, foot, and mouth disease). [12] The potential application of small molecules to treat various viral infections including enterovirus (Hand, Foot, and Mouth Disease) and SARS-CoV-2 has been discussed in popular media including the New York Times.

Ribavirin, also known as tribavirin, is an antiviral medication used to treat illness caused by respiratory syncytial virus (RSV) and hepatitis C virus (HCV) infections, as well as some viral hemorrhagic fevers. For HCV, it is used in combination with other medications, such as simeprevir, sofosbuvir, peginterferon alfa-2b or peginterferon alfa-2a. It can also be used for viral hemorrhagic fevers—specifically, for Lassa fever, Crimean–Congo hemorrhagic fever, and Hantavirus infections. Ribavirin is usually taken orally or inhaled. Despite widespread usage, it has faced scrutiny in the 21st century because of lack of proven efficacy in treating viral infections for which it has been prescribed in the past.

Gene silencing is the regulation of gene expression in a cell to prevent the expression of a certain gene. Gene silencing can occur during either transcription or translation and is often used in research. In particular, methods used to silence genes are being increasingly used to produce therapeutics to combat cancer and other diseases, such as infectious diseases and neurodegenerative disorders.

<span class="mw-page-title-main">Aptamer</span> Oligonucleotide or peptide molecules that bind specific targets

Aptamers are oligomers of artificial ssDNA, RNA, XNA, or peptide that bind a specific target molecule, or family of target molecules. They exhibit a range of affinities, with variable levels of off-target binding and are sometimes classified as chemical antibodies. Aptamers and antibodies can be used in many of the same applications, but the nucleic acid-based structure of aptamers, which are mostly oligonucleotides, is very different from the amino acid-based structure of antibodies, which are proteins. This difference can make aptamers a better choice than antibodies for some purposes.

Therapeutic gene modulation refers to the practice of altering the expression of a gene at one of various stages, with a view to alleviate some form of ailment. It differs from gene therapy in that gene modulation seeks to alter the expression of an endogenous gene whereas gene therapy concerns the introduction of a gene whose product aids the recipient directly.

Peter B. Dervan is the Bren Professor of Chemistry at the California Institute of Technology. The primary focus of his research is the development and study of small organic molecules that can sequence-specifically recognize DNA, a field in which he is an internationally recognized authority. The most important of these small molecules are pyrrole–imidazole polyamides. Dervan is credited with influencing "the course of research in organic chemistry through his studies at the interface of chemistry and biology" as a result of his work on "the chemical principles involved in sequence-specific recognition of double helical DNA". He is the recipient of many awards, including the National Medal of Science (2006).

EICAR (5-ethynyl-1-β-D-ribofuranosylimidazole-4-carboxamide) is a nucleoside analogue which has both anti-cancer and antiviral effects, and was originally developed for the treatment of leukemia, but was unsuccessful in human clinical trials. It has broad spectrum antiviral effects with activity against pox viruses, Semliki forest virus, Junin virus, reovirus, influenza, measles virus and respiratory syncytial virus among others, although it is not active against coronaviridae such as SARS-CoV-1. This useful spectrum of activity means that EICAR and related derivatives continue to be investigated for the treatment of viral diseases.
