LMU Scientist Leads Elite Research Team on COVID-19

A Loyola Marymount University assistant professor has secured a $55,000 grant from Research Corporation for Science Advancement to identify drug candidates that could stop the coronavirus, the pandemic-associated virus that causes COVID-19.

Kathryn Mouzakis of the LMU Frank R. Seaver College of Science and Engineering is leading an elite, nationwide team of researchers whose combined expertise will allow them to rapidly identify drug candidates that target a specific 3D shape in the coronavirus’ genome. RCSA’s COVID-19 Initiative, announced and implemented in April 2020, provided immediate funding for highly promising research projects that directly impact current or future pandemics.

“I am thrilled to receive this funding from RCSA,” Mouzakis said. “In addition to doing important research that may one day alleviate disease, this is a new and exciting direction for my research lab. Our results will allow our team of investigators to be competitive for future long-term funding from federal sources such as the National Institute of Allergy and Infectious Diseases.”

Mouzakis, an assistant professor of biochemistry who joined LMU in 2018 from Fort Lewis College, where she won the new faculty teaching award, is a 2017 Cottrell Scholar awardee from RCSA. Her team members are Amanda Hargrove, an associate professor of chemistry and biochemistry at Duke, a fellow 2017 Cottrell Scholar, and co-investigator receiving her own $55,000 RCSA award for this research; and collaborators Victoria D’Souza, professor of molecular and cellular biology at Harvard, Gary Brewer, professor of biochemistry and molecular biology at Rutgers, and Mei-Ling Li, a research assistant professor at Rutgers.

“Dr. Mouzakis’ work to inhibit viral replication of SARS-CoV-2 is critical in addressing the current and future viral pandemics,” said Kathleen Weaver, associate provost for research, professional development, and online learning.

The hypothesis of the team’s work is that drug-like small molecules can selectively bind and modify the function of a viral RNA structure in ways that are detrimental to the virus lifecycle. These drug-like small molecules could help someone who is already infected by limiting the course of the disease and reducing transmission.

The specific RNA structure the team is targeting, its frameshift site pseudoknot, acts in an early step in infection and may represent an Achilles’ heel for the virus. Mouzakis will contribute to this research by assessing if, and to what extent, lead compounds, identified through research efforts in Hargrove’s lab, impact the functionality of the viral frameshift site. Small molecules that selectively and significantly impact the frameshift site function will be further evaluated for their ability to stop coronavirus replication by Brewer and Li.

Mouzakis began in-lab, on-campus experiments this month, in accordance with LMU and the L.A. Department of Public Health policies.
