Process for the separation of enantiomers of an amino acid comprises treating the racemic mixture of the amino acid with glutaric anhydride and then with glutaryl 7-ACA acylase, recovering one of the enantiomers as the amino acid and the other as the corresponding glutaryl amide.クリストフサラ...

It was a formula for defeat, malarial and otherwise.[3] Exactly 30 years later, in 1891, Paul Ehrlich announced that the application of a chemical stain, methylene blue, killed malarial microorganisms and could be used to treat malaria.[4] But nothing came of Ehrlich’s breakthrough seven...
The development of live-cell fluorescence nanoscopy is powered by the availability of suitable fluorescent probes. Rhodamines are among the best fluorophores for labeling intracellular structures. Isomeric tuning is a powerful method for optimizing the b
