Natural substances show promise against coronavirus

Three natural compounds present in foods such as green tea, olive oil and red wine are promising candidates for the development of drugs against the coronavirus. In a comprehensive screening of a large library of natural ...

Experimental treatment regimen effective against HIV

Protease inhibitors are a class of antiviral drugs that are commonly used to treat HIV, the virus that causes AIDS. Scientists at the University of Nebraska Medical Center designed a new delivery system for these drugs that, ...

Chemical compounds in foods can inhibit a key SARS-CoV-2 enzyme

Chemical compounds in foods or beverages like green tea, muscadine grapes and dark chocolate can bind to and block the function of a particular enzyme, or protease, in the SARS-CoV-2 virus, according to a new study by plant ...

X-rays size up protein structure at the 'heart' of COVID-19 virus

A team of researchers at the Department of Energy's Oak Ridge and Argonne national laboratories has performed the first room-temperature X-ray measurements on the SARS-CoV-2 main protease—the enzyme that enables the virus ...

Enzyme helps cancer cells avoid genetic instability

Cancer cells are resourceful survivors with plenty of tricks for staying alive. Researchers have uncovered one of these stratagems, showing how cells lacking the tumor suppressor BRCA1 can resume one form of DNA repair, sparing ...

Microbes help beetles defeat plant defenses

Some symbiotic bacteria living inside Colorado potato beetles can trick plants into reacting to a microbial attack rather than that of a chewing herbivore, according to a team of Penn State researchers who found that the ...

New molecule has potential to help treat genetic diseases and HIV

(PhysOrg.com) -- Chemists at The University of Texas at Austin have created a molecule that's so good at tangling itself inside the double helix of a DNA sequence that it can stay there for up to 16 days before the DNA liberates ...
