Differentiation between enamines and tautomerizable imines in the oxidation reaction with TEMPO
Nature Communications, 2018 Tautomerization of imines into enamines is the basis of their similar reactivity; however, minor structural changes may lead to different outcomes. Here, the authors show that the reaction of cyclohexanone and amines in presence of TEMPO affords either α-

eLife, 2020 Abundant APOBEC3 (A3) deaminase-mediated mutations can dominate the mutational landscape (‘mutator phenotype’) of some cancers, however, the basis of this sporadic vulnerability is unknown.

How Water’s Properties Are Encoded in Its Molecular Structure and Energies
Chemical Reviews, 2017 How are water’s material properties encoded within the structure of the water molecule? This is pertinent to understanding Earth’s living systems, its materials, its geochemistry and geophysics, and a broad spectrum of its industrial chemistry. Water has

A new parametrizable model of molecular electronic structure
, 2011 A new electronic structure model is developed in which the ground state energy of a molecular system is given by a Hartree-Fock-like expression with parametrized one- and two-electron integrals over an extended (minimal + polarization) set of ...

FEBS Letters, EarlyView.Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

Autophagy in cancer and protein conformational disorders
FEBS Letters, EarlyView.Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

A stepwise emergence of evolution in the RNA world
FEBS Letters, EarlyView.How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

A Cationic Compound of Ru25⊕ Containing a Coordinated PF4O⊖ Ion
CHIMIA, 1989 The compound Ru2(PhNNNPh)4 was oxidized in CH2Cl2 with AgPF6. From a CH2Cl2/(C2H5)2O solution left to evaporate in air for one month blue-green crystals of Ru2(PhNNNPh)4OPF4, in which the PF4O⊖ ion is coordinated to one Ru atom (Ru–O: 220(1) pm), were ...
