One small atom can make a big difference in a molecule’s pharmacological properties. Especially if that atom is a nitrogen. Chemists at the University of Oklahoma have now unveiled a new strategy for ...

Researchers at the University of Oklahoma have developed a breakthrough method of adding a single nitrogen atom to molecules, unlocking new possibilities in drug research and development. Now ...

Heterocycles, molecular rings found in many pharmaceuticals, have a reputation for stubbornly resisting modification. That is, in a heterocycle, heteroatoms of one type aren’t easily swapped for ...

As a graduate student at the University of California, Berkeley, Mark Levin started sketching out ideas for how to do something no chemist had ever managed before: swapping one of the carbon atoms in ...

Red arrows indicate the nuclear spin axes at the positions of the N3 nitrogen atoms on the guanine (G) bases. Due to the helical structure of DNA, there is an angular deviation in the orientation of ...
