Milligram‐Scale Enzymatic Synthesis of Base‐Modified DNA through Primer Extension: Polymerase Synthesis and NMR Structures of DNA Containing Phenyl‐Substituted Nucleobases

ChemistryEurope, EarlyView.
Larger‐scale enzymatic synthesis of base‐modified DNA is developed using primer extension with KOD(exo‐) DNA polymerase allowing preparation of milligram amounts of the modified DNA sufficient for NMR structural analysis. Milligram (≈200 nmol) scale enzymatic synthesis of base‐modified DNA is developed based on primer extension using easily accessible ...

Investigating di‐n‐Butylcalcium

ChemistryEurope, EarlyView.
A detailed synthetic, crystallographic, and spectroscopic investigation demonstrates that the hitherto elusive di‐n‐butylcalcium is accessible and stable at low temperature, and can be used for deprotometallation reactions. The synthesis and detailed characterization by NMR spectroscopy of di‐n‐butylcalcium are reported. The reaction of [Ca{N(SiMe3)2}2.

Synthesis of Cyclic Sulfilimines and Sulfoximines via Copper‐Mediated C(sp2)–H Sulfanylation of Benzylamines with a Catalytic Transient Directing Group

ChemistryEurope, EarlyView.
Copper‐mediated transient C─H sulfanylation of benzylamines with sulfenamides enables rapid access to thioethers, cyclic sulfilimines, and sulfoximines. Mechanistic investigations using 1H NMR and electron paramagnetic resonance spectroscopy reveal an unprecedented thermally induced homolytic cleavage of the sulfenamide N─S bond, slowly releasing the ...

Coupling times with ambiguities for particle systems and applications to context-dependent DNA substitution models

, 2007
We define a notion of coupling time with ambiguities for interacting particle systems, and show how this can be used to prove ergodicity and to bound the convergence time to equilibrium and the decay of correlations at equilibrium.

Redesigning a One‐Phase Enzymatic Assay to Streamline High‐Throughput Screening of Phytoene Desaturase Inhibitors

ChemFoodChem, EarlyView.
A one‐phase in vitro PDS enzyme activity assay is designed as a simple and efficient method, enabling the enhancement of substrate‐enzyme interaction and the elimination of the adverse effects of organic solvents on enzyme activity. It provides a rapid and direct evaluation method for high‐throughput screening of potent PDS inhibitors instead of using ...
