Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges

Angewandte Chemie International Edition, EarlyView.
Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.

Unlocking Catalyst Activation as a Critical Bottleneck in Cross‐Coupling Reactions: Room‐Temperature Couplings of Weak Nucleophiles Enabled by [Pd(1‐MeNAP)TFA]2 Precatalysts

Angewandte Chemie International Edition, EarlyView.
In many Pd‐catalyzed cross‐couplings, catalyst performance has been found to be limited by catalyst activation. Methylnaphthyl (MeNAP) palladium trifluoroacetate dimers are presented as easy‐to‐store and easy‐to‐handle precursors, which rapidly activate under reaction conditions, even when only weakly coordinating, non‐reducing nucleophiles are present.

Pursing Quinoline-8-Sulfonamide derivatives for the identification of potent NPPs inhibitors: In silico molecular docking, molecular dynamics simulations and density field theory (DFT) studies

Results in Chemistry
Nucleotide pyrophosphatase/phosphodiesterase (NPP) enzymes belong to a broad category of ectonucleotidase enzymes. These NPPs are responsible for hydrolysis of extracellular nucleotides (ATP to AMP) and are therefore important regulators in the ...
