Hemp to prevent COVID? New study shows cannabinoid acids prevent the virus from entering human cells

Researchers at Oregon State University (OSU) say they have invented a technique via chemical screening that shows the ability of hemp compounds to prevent the virus that causes COVID-19 from entering human cells.

Findings of the study led by Richard van Breemen, a researcher with Oregon State’s Global Hemp Innovation Center, College of Pharmacy and Linus Pauling Institute, were published today in the Journal of Natural Products, according to the OSu website.

The research team 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 compounds are cannabigerolic acid, or CBGA, and cannabidiolic acid, CBDA, and the spike protein is the same drug target used in COVID-19 vaccines and antibody therapy.

“These cannabinoid acids are abundant in hemp and in many hemp extracts,” van Breemen said. “They are not controlled substances like THC, the psychoactive ingredient in marijuana, and have a good safety profile in humans. And our research showed the hemp compounds were equally effective against variants of SARS-CoV-2, including variant B.1.1.7, which was first detected in the United Kingdom, and variant B.1.351, first detected in South Africa.”

Those two variants are also known the alpha and beta variant, respectively.

Van Breemen says acids from the hemp “could be used to prevent SARS-CoV-2 infection and also to shorten infections by preventing virus particles from infecting human cells. They bind to the spike proteins so those proteins can’t bind to the ACE2 enzyme, which is abundant on the outer membrane of endothelial cells in the lungs and other organs.”
