Reaction-noise induced homochirality

, 2006
Starting from the chemical master equation, we employ field theoretic techniques to derive Langevin-type equations that exactly describe the stochastic dynamics of the Frank chiral amplification model with spatial diffusion.

N-Methylimidazole Promotes The Reaction Of Homophthalic Anhydride With Imines [PDF]

, 2014
The addition of N-methylimidazole (NMI) to the reaction of homophthalic anhydride with imines such as pyridine-3-carboxaldehyde-N-trifluoroethylimine (9) reduces the amount of elimination byproduct and improves the yield of the formal cycloadduct ...

Electrically Readable Lateral Flow Assay Using Organic Transistors for Diagnostic Applications

Advanced Materials, EarlyView.
Electrolyte‐gated organic field‐effect transistors (EGOFETs) are integrated with lateral flow (LF) paper fluidics to create a reusable, portable, and low‐cost point‐of‐care (PoC) diagnostic test. The devices are validated for Human Immunoglobulin G detection, achieving high sensitivity (0.1 fm), selectivity, and reproducibility with rapid results in 20–

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.

(3R*,5′S*)-6,7-Dimethoxy-3-(4′-methoxy-6′-methyl-5′,6′,7′,8′-tetrahydro-1,3-dioxolo[4,5-g]isoquinolin-5′-yl)isobenzofuran-1(3H)-one (racemic α-noscapine)

Acta Crystallographica Section E, 2010
In the racemic title compound, C22H23NO7, the dihedral angle between the fused ring systems is 51.87 (6)°. Two of the methoxy groups are disordered over two orientations in 0.688 (5):0.312 (5) and 0.672&#8197 ...

Chirality Selection in Open Flow Systems and in Polymerization

, 2005
As an attempt to understand the homochirality of organic molecules in life, a chemical reaction model is proposed where the production of chiral monomers from achiral substrate is catalyzed by the polymers of the same enatiomeric type. This system has to

Second‐Generation Crystalline Sponges Enabling Consistent Structure Analysis Under Standardized Conditions for Diverse Molecules

Angewandte Chemie, EarlyView.
The second‐generation crystalline sponge method allows structurally diverse molecular guests to crystallize under standardized crystallization conditions. The key is the predominant packing type of cages and anions in crystals. ABSTRACT Crystallization is typically highly sensitive to even minor structural differences in target molecules.

Racemic 4-(4-tert-butylphenyl)-2,6-dimethylcyclohex-3-enecarboxylic acid

Acta Crystallographica Section E, 2008
The chirality of the title compound, C19H26O2, is solely generated by the presence of the double bond in the cyclohexene ring. This compound was synthesized to study the interaction of the two enantiomers in the solid state.

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 ...
