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 ...

Methyl 2-amino-4,5-dimethoxybenzoate
Acta Crystallographica Section E, 2013 The title compound, C10H13NO4, is essentially planar, with an r.m.s. deviation of 0.049 Å. An intramolecular C—H...O hydrogen bond occurs and the amino group forms an intramolecular N—H...Oester hydrogen bond; the other H atom ...

Supercritical Water is not Hydrogen Bonded [PDF]
Angewandte Chemie, 2020 AbstractThinking about water is inextricably linked to hydrogen bonds, which are highly directional in character and determine the unique structure of water, in particular its tetrahedral H‐bond network. Here, we assess if this common connotation also holds for supercritical water.

FEBS Letters, EarlyView.The enzyme 5‐lipoxygenase (5‐LOX) catalyzes the first step in the biosynthesis of leukotrienes (LTs) involved in inflammatory pathophysiology. After cellular stimulation, 5‐LOX translocates to the nucleus, interacting with the 5‐LOX‐activating protein (FLAP) to form LTA4 from arachidonic acid (AA).

2-[(4-Methylbenzoyl)hydrazono]propionic acid monohydrate
Acta Crystallographica Section E, 2009 In the title compound, C11H12N2O3·H2O, the water molecule is a hydrogen-bond donor to the double-bond amide and the carbonyl O atoms of two acid molecules; it is also a hydrogen-bond acceptor to the acid –OH and amide –NH– groups ...

FEBS Letters, EarlyView.UDP‐glucuronic acid 4‐epimerase (UGAepi) catalyzes NAD+‐dependent interconversion of UDP‐glucuronic acid (UDP‐GlcA) and UDP‐galacturonic acid (UDP‐GalA) via C4‐oxidation, 4‐keto‐intermediate rotation, and C4‐reduction. Here, Borg et al. examined the role of the substrate's carboxylate group in the enzymic mechanism by analyzing NADH‐dependent reduction

Beilstein Journal of Organic Chemistry, 2013 Activation of the C–F bond of benzylic fluorides was achieved using 1,1,1-tris(hydroxymethyl)propane (2) as a hydrogen bond-donating agent. Investigations demonstrated that hydrogen bond-donating solvents are promoting the activation and hydrogen bond ...

A model for the hydrogen bond [PDF]
Proceedings of the National Academy of Sciences, 1975 A model of the linear hydrogen bond has been devised which is characterized by three physical parameters of the isolated electron donor and proton donor molecules: μ A-H , the bond dipole moment; Δ I , the difference in ionization potential between that of the electron donor and the ...
