A structure of the drug ibrutinib. The drug ibrutinib makes a covalent bond to Bruton's tyrosine kinase, an important cancer target. Credit: RCSB PDB/Yang H. Ku Enticing atoms to share their electrons ...
A research group has successfully demonstrated that carbon-carbon (C-C) covalent bonds expand and contract flexibly in response to light and heat. This unexpected flexibility of C-C bonds could confer ...
In the past few years, drug-discovery researchers have become increasingly interested in covalent inhibitors — compounds that bind and inhibit a target protein by forming a covalent bond to it 1, 2, ...
A research team from Hokkaido University has confirmed a century-old theory by discovering a stable single-electron covalent bond, known as a sigma bond, between two carbon atoms. This unique bond ...
