Diastereomers are structurally identical molecules that are not mirror images of each other. Diastereomers can have different biological activities, potencies or toxicities, which means they can ...

Chemists have constructed the complex natural products secalosides A and B from simple chemical building blocks for the first time. The total synthesis has been key to identifying the molecules’ ...

Abstract: In this letter, symmetry-broken silicon cuboid tetramer clusters (SSCTC) have been proposed for optical separation of enantiomers, leveraging the enhanced electromagnetic field generated by ...

Objectives The primary objective of this focused literature review was to determine whether clinically significant differences exist in the efficacy and safety of commonly prescribed racemic mixtures ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Separating stereoisomers is an extensively researched and challenging process, with approved substances being rare. A new SFC-based system was made to possibly ease some aspects of these procedures.

Scientists have made a significant leap forward in the field of chiral molecules. The team achieved near-complete separation in quantum states for these essential components of life. This discovery ...

L-DOPA is the best drug we have for Parkinson’s disease, but its molecular mirror image, D-DOPA, causes dangerous side effects. Making L-DOPA without also making D-DOPA is surprisingly hard and ...
