A new light-activated catalyst breaks and resets carbon–halogen bonds to convert racemic mixtures into enantiomerically enriched products. It is the first time that such a technique has targeted bonds ...

Enantiopure hydrogen-bond donor (HBD) molecules enabled sharp, complete magnetic transitions, while racemic mixtures led to disordered structures with broad, incomplete transitions. This ...

so chemists call these kinds of mixtures racemic mixtures. So that is the situation back in the 1960s when this paper in "The New England Journal of Medicine" comes out. Now, this describes a ...

Due to this fact, fully recognized today, the pharmaceutical industry has been forced to market pure enantiomers instead of the racemic mixture whenever a chiral compound is involved. The simulated ...

Researchers have developed a new model for achiral chromatography (ACh) that can separate non-racemic mixtures of enantiomers. Researchers at Rzeszow University of Technology in Poland have developed ...

Likewise, amphetamine can exist in two mirror-image forms called enantiomers, which exist in a 50-50 mixture called a racemate aka a racemic mixture. (For a detailed discussion of enantiomers, see ...

Previous research has shown that praziquantel is a racemic mixture (1:1) of two enantiomers—ie, mirrored compounds of R-praziquantel (L-praziquantel enantiomer) and S-praziquantel (D-praziquantel ...

Implications for practice: There is no evidence either supporting or refuting the use of inhaled nebulized racemic epinephrine in newborn infants. Implications for research: randomised controlled ...

Thioctic acid is a natural antioxidant existing as two optical isomers, but most clinically used as racemic mixture. The present study investigated the central nervous system’s changes which followed ...

Reaction mixtures were incubated on a rotary shaker for 2 or 7 days (135 rpm, 25°C), respectively. Resolution of the racemic mixture (3.19 mM) of 1-amino-1-(3′pirydyl)methylphosphonic acid (2) was ...
