Immunological Abnormalities and Hydantoins [PDF]

open access: yesBMJ, 1972
Various immunological features were measured in 20 patients with epilepsy who had received prolonged treatment with hydantoins. Immunoglobulin A (IgA) was shown to be absent or low in five patients, beta(1)C/A was low in 10 patients. Five patients showed negative reactions to skin tests, and two could not be sensitized to dinitrochlorobenzene.

Synthesis and Crystal Structures of 1,1′-Methylene-bis(imidazolidine-2,4-dione) and Alkali Metal Salts

open access: yesCrystals, 2014
Single-crystal structures of 1,1′-methylenebis(imidazolidine-2,4-dione) and its sodium and dipotassium salts were determined. Powder X-ray diffraction was also employed to characterize the bulk materials and those phases which did not yield single ...

Electron-donating Effect of Hydantoin Derivative Inhibitor on the Enhanced Anticorrosion Capacity for Mild Steel in Hydrochloric Acid Medium

open access: yesInternational Journal of Electrochemical Science, 2022
Hydantoin (HDT) and its derivative (allantoin, ALT) were evaluated as corrosion inhibitors for 20# steel in 1 M HCl solution at 303 K through gravimetric test, potentiodynamic polarization, electrochemical impedance spectroscopy and surface analysis ...

Revisiting the SAR of the antischistosomal aryl hydantoin (Ro 13-3978) [PDF]

open access: yes, 2016
The aryl hydantoin 1 (Ro 13-3978) was identified in the early 1980s as a promising antischistosomal lead compound. However, this series of aryl hydantoins produced antiandrogenic side effects in the host, a not unexpected outcome given their close ...

UV-VIS, Surface Morphology and Electrochemical Study of Cobalt Electrodeposition from Choline Chloride-ethylene Glycol Liquid Mixture

open access: yesInternational Journal of Electrochemical Science, 2021
In this report, we present a simple, efficient and promising methodology of electroplating cobalt in the mixture of choline chloride and ethylene glycol in 1:2 mol ratio in the presence of hydantoin (HD) as an additive.

Application of electron paramagnetic resonance Spectroscopy for validation of the novel (AN plus DN) solvent polarity scale [PDF]

open access: yes, 2008
Based on solvation studies of polymers, the sum (1: 1) of the electron acceptor (AN) and electron donor (DN) values of solvents has been proposed as an alternative polarity scale.

Modeling, substrate docking, and mutational analysis identify residues essential for the function and specificity of a eukaryotic purine-cytosine NCS1 transporter [PDF]

open access: yes, 2012
Background: The purine-cytosine FcyB transporter is a prototype member of the NCS1 family. Results: Using homology modeling, substrate docking, and rational mutational analysis, we identify residues critical for function and specificity.
