Metal free direct C(sp2)–H arylaminations using nitrosoarenes to 2-hydroxy-di(het)aryl amines as multifunctional Aβ-aggregation modulators
A direct C(sp2)–H arylamination of 2-hydroxyarenes using nitrosoarenes was achieved under metal free conditions without the aid of additional reagents/steps for N–O bond cleavage.
Relative orientation of the carbonyl groups determines the nature of orbital interactions in carbonyl–carbonyl short contacts
The nature of orbital interactions in a carbonyl–carbonyl short contact is determined by the relative orientation of the two interacting carbonyl groups.
Cu2+ selective chelators relieve copper-induced oxidative stress in vivo
We report highly selective, novel Cu2+ chelators that relieve copper induced oxidative stress in vivo indicating applicability toward assuaging copper-overload disorders.
Mechanoresponsive and recyclable biocatalytic sponges from enzyme-polymer surfactant conjugates and nanoparticles
The fabrication of biocatalytic, porous, recyclable, and mechanoresponsive elastic sponge like material is shown from a mixture of core–shell alkaline phosphatase-polymer surfactant bioconjugates and nanoparticles.
Solvation and hydrogen bonding aided efficient non-radiative deactivation of polar excited state of 5-aminoquinoline
The mechanism of efficient fluorescence quenching of 5-aminoquinoline in alcoholic solvents.
Hydrogen bond induced enhancement of Fermi resonances in N–H⋯N hydrogen bonded complexes of anilines
Enhancement of Fermi resonance intensities due to the formation of N–H⋯N hydrogen bonding of anilines with alkyl amines is analyzed using a two-state deperturbation model.
Selective synthesis of mono- and di-methylated amines using methanol and sodium azide as C1 and N1 sources
The selective synthesis of various N,N-dimethylated and N-monomethylated amines from organic azides using methanol as a methylating agent is reported.
The role of electronegativity on the extent of nitridation of group 5 metals as revealed by reactions of tantalum cluster cations with ammonia molecules
The electronegativity of the metal (V > Ta) plays a key role in determining the composition of the metal nitrides.
Optically sensing phospholipid induced coil–helix transitions in the phosphoinositide-binding motif of gelsolin
A FRET-based probe reveals that coil–helix transitions in the phospholipid binding sequence of gelsolin occur at physiological phosphatidylinositol-4,5-bisphosphate concentrations.
Optical backbone-sidechain charge transfer transitions in proteins sensitive to secondary structure and modifications
We report the UV-vis absorption originating from protein backbone-sidechain charge transfer transitions in charged amino acids with anionic and cationic sidechains.
Controlling anticancer drug mediated G-quadruplex formation and stabilization by a molecular container
G-quadruplex DNA (GQ-DNA) formation has been controlled using a molecular container, cucurbituril (CB7), by means of translocating a potential anticancer drug, topotecan, from GQ-DNA to the CB7 nanocavity. Interestingly, this whole cycle can be easily monitored through the change in the emission color of the stabilizing ligand, i.e., topotecan.
