Morphology of the rat knee joint after intraarticular injection of hydroxymethyl-quinoxaline dioxide

Medičnì Perspektivi, 2022
Topical antiseptics are widely used in orthopedics and traumatology. However, studies highlighting the effects of antiseptics during long-term use on joint tissues are limited. In the performed work, the peculiarities of the structure of intra-articular

Investigation of the key active intermediate for the synthesis of 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane: Hydrolysis and nitrolysis of 1-acetoxymethyl-3,5,7-trinitro-1,3,5,7-tetraazacyclooctane

Energetic Materials Frontiers, 2020
The problem whether 1-hydroxylmethyl-3,5,7-trinitro-1,3,5,7-tetraazacyclooctane is the key active intermediate for the synthesis of 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane (HMX) from urotropine or 3,7-dinitro-1,3,5,7-tetraazabicyclo[3.3.1]nonane ...

Enhanced selectivity of hydrogel-based molecularly imprinted polymers (HydroMIPs) following buffer conditioning. [PDF]

, 2013
We have investigated the effect of buffer solution composition and pH during the preparation, washing and re-loading phases within a family of acrylamide-based molecularly imprinted polymers (MIPs) for bovine haemoglobin (BHb), equine myoglobin (EMb) and

Synthesis and Anti-Hepatitis B Activities of 3′-Fluoro-2′-Substituted Apionucleosides

Molecules, 2022
Nucleoside analogues have excellent records as anti-HBV drugs. Chronic infections require long-term administration ultimately leading to drug resistance. Therefore, the search for nucleosides with novel scaffolds is of high importance. Here we report the

A general model for analysis of linear and hyperbolic enzyme inhibition mechanisms

FEBS Open Bio, EarlyView.
We developed a general enzyme kinetic model that integrates these six basic inhibition mechanism onto a single one. From this model, we deduced a general enzyme kinetic equation that through modulation of simple parameters, γ (the relative inhibitor affinity for two binding sites) and β (the reactivity of the enzyme–substrate–inhibitor complex), is ...

NEW N-GLUCOSYLATED SUBSTITUTED ANILINES [PDF]

Chemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2015
The reaction of (+)-D-glucose with 4-chloroaniline or 3,5-dibromoaniline leads almost exclusively to the β-configuration of glucosylated anilines. The acetylating of 2-(3,5-dibromophenylamino)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol is less ...

Polyoxometalate (POM)-layered double hydroxides (LDH) composite materials: design and catalytic applications [PDF]

, 2017
Layered double hydroxides (LDHs) are an important large class of two-dimensional (2D) anionic lamellar materials that possess flexible modular structure, facile exchangeability of inter-lamellar guest anions and uniform distribution of metal cations in ...

SmallTalk: a novel small‐sized fusion tag for peptide expression and purification

FEBS Open Bio, EarlyView.
The SmallTalk fusion tag allows for the efficient expression and purification of soluble recombinant proteins or peptides in Escherichia coli. Testing with SmallTalk‐GFP confirmed that the proteins were soluble and folded correctly, while SmallTalk‐Bin1b maintained its antimicrobial activity against various bacterial isolates. This streamlined workflow

The Issue of Misidentification of Kojic Acid with Flufuran in Aspergillus flavus

Molecules, 2019
In the course of investigations on the complex phenomenon of bee decline, Aspergillus flavus was isolated from the haemocoel of worker bees. Observations on the metabolomic profile of this strain showed kojic acid to be the dominant product in cultures ...
