Eutectozymes as Soft Hybrid Materials for Advanced Biocatalysis

Advanced Materials, EarlyView.
Eutectozymes are sustainable hybrid materials that embed a GOx–HRP cascade within hydrophobic eutectogels featuring a dual supramolecular–covalent network. This architecture preserves native enzyme structure and stability, enables efficient heterogeneous biocatalysis in aqueous media, and positions eutectogels as robust platforms for next‐generation ...

Direct Vasocontractile Activities of Bupivacaine Enantiomers on the Isolated Rat Thoracic Aorta

Anesthesiology Research and Practice, 2010
Background. In vitro studies with isolated arteries have shown direct vasoactivity of racemic bupivacaine. However, there is little information on the direct vasoactivities of bupivacaine enantiomers, S(−)- and R(+)-bupivacaine. Methods.

Nucleation behaviour of racemic and enantiopure histidine [PDF]

, 2021
International audienceNucleation of DL-and L-histidine is examined using induction time measurements and their nucleation rates have been deduced. Results indicate a much slower nucleation for the racemic form compared to the pure enantiomer form.

Pasteur made simple – mechanochemical transformation of racemic amino acid crystals into racemic conglomerate crystals [PDF]

, 2020
Conglomerate crystallization is required for many deracemization or enantioenrichment protocols. Here, we report the metal-mediated mechanochemical transformation of racemic compounds of some proteinogenic amino acids – valine, leucine and isoleucine ...
