Using natural products such as hemp to treat COVID-19 will be the topic of Oregon State University's Science Pub event at 6 p.m. Dec. 6.
The free event, which can be attended in person at the Old World Deli in Corvallis or viewed online, will feature a presentation by Richard van Breemen, a professor of pharmaceutical sciences at Oregon State. The presentation is titled “Natural products and hemp: Under-appreciated sources for COVID-19 therapeutic agents.”
Earlier this year, van Breemen and a team of researchers identified hemp compounds that show the ability to prevent the virus that causes COVID-19 from entering human cells. The researchers found that a pair of cannabinoid acids bind to the SARS-CoV-2 spike protein, blocking a critical step in the process the virus uses to infect people.
The findings were published in the Journal of Natural Products and set records for downloads and online views, and were covered by more than 400 news agencies around the world.
While natural products account for about half of all drugs currently in use, van Breemen said natural drug discovery research is not a priority of major pharmaceutical companies and federal funding agencies.
Hemp is a particularly rich source of unique natural products, many of which have pharmacological activity, van Breemen said. Propagation of hemp was prohibited in the U.S. from 1936 until 2014, and he said many restrictions remain in effect.
With the passage of the U.S. Farm Bill in 2014, hemp cultivation and hemp-based products grew. The COVID-19 pandemic inspired a surge in natural products research for the discovery of new antiviral agents, and several laboratories around the world, including van Breemen’s, reported that certain cannabinoids from hemp exhibit anti-SARS-CoV-2 activity.
Sponsors of Science Pub include the Oregon Museum of Science and Industry, Old World Deli, Oregon State Research Office and Oregon State University.
