Notably, the paper also includes simulation studies outlining when dDRTC is most effective, positioning it as a practical ...

Halogen bonds were first proposed as an activating interaction in 2008, but this alternative type of organocatalysis was ...

Prior to 2000, many drugs that formed a covalent bond with targets did so non-selectively, which often led to undesired side effects when compared to non-covalent drugs. This led to the belief that ...

The distribution of outermost shell electrons, known as valence electrons, of organic molecules was observed for the first time. As the interactions between atoms are governed by the valence electrons ...

Scientists mapped where drugs bind inside the body, cell by cell, to better understand benefits and side effects.
