The Enantiomers of Trinorbornane and Derivatives Thereof [PDF]
, 2020 Herein, we report the synthesis of the enantiomers of trinorbornane, a tetracyclic saturated hydrocarbon with the chemical formula C11H16. The preparation of these rigid carbon scaffolds was enabled by the successful chiral separation of its tricyclic ...

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Isolation of enantiomers via diastereomer crystallisation [PDF]
, 2010 Enantiomer separation remains an important technique for obtaining optically active materials. Even though the enantiomers have identical physical properties, the difference in their biological activities make it important to separate them, in order ...

Tropical Medicine and Infectious Disease, 2022 Malaria is one of the deadliest tropical diseases, especially causing havoc in children under the age of five in Africa. Although the disease is treatable, the rapid development of drug resistant parasites against frontline drugs requires the search for ...

Resolutions of racemates by crystallization : additives and attrition [PDF]
, 2009 Although biological processes in simple bacteria or rather complex animals such as humans exclusively form left or right-handed molecules, in a normal chemical reaction, carried out in a laboratory, equal amounts of left and right-handed molecules ...
