Study identifies novel inhibitors against SARS-CoV-2 main protease

In a recent study posted to the bioRxiv* server, researchers at the University of Arizona screened ~11 million severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) main protease (MPro)-inhibiting small compounds in the ZINC15 database using a structure-based in-silico screening method.

Scientists unravel the molecular origin of rare genetic disease cystinosis

The rare genetic disease cystinosis is caused by mutations in the gene for a protein called cystinosin. A team of scientists has now solved the structure of cystinosin and determined how mutations interfere with its normal function, providing insights into the underlying mechanisms and suggesting a way to develop new treatments for the disease.

Discovery suggests a new way to slow or stop metastatic spread of pancreatic cancer

Pancreatic cancer, though rare, is one of the deadliest of cancers, killing nearly 50,000 people yearly and doing so quickly, primarily because it metastasizes rapidly through the body. Barely one in 10 people survive beyond five years.
