(4Z)-1-Benzyl-4-(2-oxopropylidene)-2,3,4,5-tetrahydro-1H-1,5-benzodiazepin-2-one

open access: yesIUCrData, 2016
The title compound, C19H18N2O2, crystallizes with two independent molecules in the asymmetric unit which differ in conformation. The seven-membered ring adopts a `bowl' conformation with the benzyl group oriented away from the open face in one molecule ...

The influence of copper on zinc oxide properties – a review

open access: yesVìsnik Harkìvsʹkogo nacìonalʹnogo unìversitetu ìmenì V.N. Karazìna. Serìâ: fìzika., 2021
ZnO has been experiencing a research renaissance for several years due to its promising electronics and gas sensing properties. It has a relatively big Eg = 3.37 eV at room temperature, a considerable exciton binding energy (60 meV), and exhibits n-type ...

Crystal structure of nuarimol [PDF]

open access: yesActa Crystallographica Section E Crystallographic Communications, 2015
The title compound [systematic name: (RS)-(2-chlorophenyl)(4-fluorophenyl)(pyrimidin-5-yl)methanol], C17H12ClFN2O, is a pyrimidine fungicide. The asymmetric unit comprises two independent molecules,AandB, in which the dihedral angles between the plane of the pyrimidine ring and those of the chlorophenyl and fluorophenyl rings are 71.10 (6) and 70.04 (5)

Crystal structure of serotonin

open access: yesActa Crystallographica Section E Crystallographic Communications, 2022
The title compound, serotonin or 5-hydroxytryptamine (5-HT) [systematic name: 3-(2-aminoethyl)-1H-indol-5-ol], C10H12N2O, has one molecule in the asymmetric unit. The conformation of the ethylamino side chain is gauche–gauche [Ca—Ca—Cm—Cm and Ca—Cm—Cm—N (a = aromatic, m = methylene) torsion angles = −64.2 (3) and −61.9 (2)°, respectively].

Mechanistic basis for inhibition of the extended‐spectrum β‐lactamase GES‐1 by enmetazobactam and tazobactam

open access: yesFEBS Letters, EarlyView.
Antimicrobial resistance (AMR) is of huge importance, resulting in over 1 million deaths each year. Here, we describe how a new drug, enmetazobactam, designed to help fight resistant bacterial diseases, inhibits a key enzyme (GES‐1) responsible for AMR. Our data show it is a more potent inhibitor than the related tazobactam, with high‐level computation

Solution Structures of \u3cem\u3eMycobacterium tuberculosis\u3c/em\u3e Thioredoxin C and Models of Intact Thioredoxin System Suggest New Approaches to Inhibitor and Drug Design [PDF]

open access: yes, 2013
Here, we report the NMR solution structures of Mycobacterium tuberculosis (M. tuberculosis) thioredoxin C in both oxidized and reduced states, with discussion of structural changes that occur in going between redox states.

Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission‐blocking target

open access: yesFEBS Letters, EarlyView.
This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.

(4Z)-4-(2-Oxopropylidene)-1,3-bis(prop-2-en-1-yl)-2,3,4,5-tetrahydro-1H-1,5-benzodiazepin-2-one

open access: yesIUCrData, 2017
In the title compound, C18H20N2O2, the diazepin-2-one ring adopts a tub conformation. The conformation of the acetyl group is partially determined by an intramolecular N—H...O hydrogen bond.
