A variety of bis heterocycles, oxazolyl/thiazolyl/imidazolyl oxadiazoles having a styryl sulfonylmethyl group at the 5-position of oxadiazole and tris heterocycles having a pyrrolyl/pyrazolyl sulfonylmethyl group at the 5-position of oxadiazole were prepared adopting simple and versatile synthetic methodologies. All the compounds were screened for their antioxidant activities. Compound 5b displayed radical scavenging activity in all the three methods greater than the standard ascorbic acid, whereas compounds 8b and 14b showed activities equal to the standard ascorbic acid.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
