Dual role of imidazole as activator/inhibitor of sweet almond (Prunus dulcis) β-glucosidase

open access: yesBiochemistry and Biophysics Reports, 2017
The activity of Prunus dulcis (sweet almond) β-glucosidase at the expense of p-nitrophenyl-β-d-glucopyranoside at pH 6 was determined, both under steady-state and pre-steady-state conditions. Using crude enzyme preparations, competitive inhibition by 1–5

Magnesium and imidazole propionate

open access: yesClinical Nutrition ESPEN, 2021
Circulating levels of imidazole propionate (ImP), a microbial metabolite of histidine, were higher in participants with type 2 diabetes (T2D) compared to those without and also induced insulin resistance. We hypothesize that low intake of magnesium (Mg) and/or low body Mg status in humans may lead to low Mg concentrations in gut microbiota, and, in ...

Coarse-grained versus fully atomistic machine learning for zeolitic imidazolate frameworks [PDF]

open access: yesarXiv, 2023
Zeolitic imidazolate frameworks are widely thought of as being analogous to inorganic AB$_{2}$ phases. We test the validity of this assumption by comparing simplified and fully atomistic machine-learning models for local environments in ZIFs. Our work addresses the central question to what extent chemical information can be "coarse-grained" in hybrid ...

Electron-induced chemistry in imidazole clusters embedded in helium nanodroplets [PDF]

open access: yesEur. Phys. J. D 72 (2018) 38, 2018
Electron-induced chemistry in imidazole (IMI) clusters embedded in helium nanodroplets (with an average size of 2$\times$10$^5$ He atoms) has been investigated with high-resoluton time-of-flight mass spectrometry. The formation of both, negative and positive, ions was monitored as a function of the cluster size n.

Study of synthesis of 2-(2-alkoxyphenyl)-1H-imidazoles. Comparison of oxidative aromatization reactions of imidazolines [PDF]

open access: yes, 2006
The reaction of methyl salicylate with ethane-1,2-diamine has been used to prepare 2-(2-hydroxyphenyl)-1H-imidazoline. This compound was alkylated with alkyl halides to give five new 2-(2-alkoxyphenyl)-1H-imidazolines (alkyl = propyl, isopropyl, isobutyl,

Metabolism of Imidazole by a Pseudomonad [PDF]

open access: yesJournal of Bacteriology, 1971
Intermediates formed during the microbial degradation of imidazole, namely 4(5)-imidazolone, formiminoglycine, and possibly glycine, are similar to those formed during metabolism of imidazole derivatives.

Thermal and mechanical stability of zeolitic imidazolate frameworks polymorphs [PDF]

open access: yesAPL Materials, 2, 124110 (2014), 2014
Theoretical studies on the experimental feasibility of hypothetical Zeolitic Imidazolate Frameworks (ZIF) have focused so far on relative energy of various polymorphs, by energy minimization at the quantum chemical level. We present here a systematic study of stability of 18 ZIFs as a function of temperature and pressure, by molecular dynamics ...

Synthesis and photophysical properties of benzoxazolyl-imidazole and benzothiazolyl-imidazole conjugates

open access: yesRSC Advances, 2021
The effect of heteroatoms on the structural and photophysical properties of donor-π-acceptor molecules, comprising imidazole and benzoxazolyl as well as imidazole and benzothiazolyl units, was investigated.
