Rapid determination of serum albumin partition coefficients using affinity chromatography

Environmental Advances, 2022
Sorption to serum albumin is essential for characterizing the distribution of chemicals in organisms. It impacts the concentration of the freely dissolved chemical in vivo and in vitro, and needs to be considered when effect concentrations at the target ...

Effects of solvent and structure on the reactivity of 6-substituted nicotinic acids with diazodiphenylmethane in aprotic solvents [PDF]

Journal of the Serbian Chemical Society, 2009
The rate constants for the reactions of diazodiphenylmethane (DDM) with 6-substituted nicotinic acids in aprotic solvents at 30°C were determined. The obtained second order rate constants in aprotic solvents, together with literature data for benzoic and

Revisiting the Total Hildebrand and Partial Hansen Solubility Parameters of Analgesic Drug Meloxicam

Liquids, 2023
The reported total Hildebrand solubility parameter (δ2) value of meloxicam, as calculated based on the group contribution method proposed by Fedors, was compared with those estimated based on the maximum solubility peaks observed in different aqueous ...

Heterometallic Coordination Compounds with Amino‐Acid Dithiocarbamate Ligands

European Journal of Inorganic Chemistry, Volume 28, Issue 13, May 21, 2025.
This comprehensive review surveys the synthesis, molecular structures, and properties of heterobimetallic coordination compounds with amino‐acid dithiocarbamate ligands (AA‐DTCs), important O,S‐ditopic ligands. Most of the known compounds form infinite assemblies of different dimensions rather than molecular entities in the solid state.

A 19F Solvatomagnetic Comparison Method for the Determination of the α1 Scale of Solvent Hydrogen‐Bond Donation and Its Application to Deep Eutectic Solvents

Journal of Physical Organic Chemistry, Volume 38, Issue 1, January 2025.
A single 19F NMR spectrum of a solution of 4‐fluoro‐2‐methylpyridine and of 4‐fluoronitrobenzene yields the hydrogen‐bond donation parameter α1 of the solvent, through the solvatomagnetic comparison method. ABSTRACT We develop a nonsolvatochromic comparison method for the determination of the α1 scale of solvent hydrogen‐bond acidity by means of 19F ...

Carbonyl stretching vibrations of 5-halogen-2-thiophenecarboxaldehydes: KBM, AN, SWAIN and LSER parameters

Pamukkale University Journal of Engineering Sciences, 2016
Halogen and solvent influence on the conformational stability and carbonyl stretching vibration of 5-Halogeno-2-thiophene-carboxaldehydes (C5H3XOS; X=F, Cl or Br) were investigated by the density functional theory using the B3LYP functional, 6-311+G(3df,p) basis set and polarizable continuum model. Calculations were performed by the cis and trans forms

Correlation study of retention data and antimalarial activity of 1,2,4,5-mixed tetraoxanes with their molecular structure descriptors and LSER parameters [PDF]

Journal of Pharmaceutical and Biomedical Analysis, 2014
The chromatographic behavior of mixed 1,2,4,5-tetraoxanes, cholic and deoxycholic acid derivatives with distinct biological activity, was examined by high-performance thin-layer chromatography in order to correlate their structure and retention. Chromatographic systems were consisted of RP-18 or CN-silica as stationary phase, and binary mixtures of ...

RETRACTED: Tolerable random interruption duration based reliability estimation of stand alone hybrid renewable energy system by network reduction and sequential Monte Carlo simulation

IET Generation, Transmission &Distribution, Volume 18, Issue 24, Page 4168-4179, December 2024.
This paper evaluates reliability indices for a stand‐alone hybrid renewable energy system under the consideration of tolerable random interruption duration in the event of down time. Abstract This paper presents a novel tolerable random interruption duration (TRID) concept for estimation of reliability indices of stand‐alone hybrid renewable energy ...

A detailed mathematical model of the human atrial cardiomyocyte: integration of electrophysiology and cardiomechanics

The Journal of Physiology, Volume 602, Issue 18, Page 4543-4583, 15 September 2024.
Abstract figure legend Three phases of novel human atrial electromechanically coupled model, MBS2023. Phase 1 deals with model development, the conceptual background, and the coupling of forward and backward pathways. Phase 2 is based on calibration of parameters related to contraction, stretch activated channels, and Ca2+ handling.
