Dietary antioxidants prevent alcohol-induced ciliary dysfunction

Previously we have shown that chronic alcohol intake causes alcohol-induced ciliary dysfunction (AICD), leading to non-responsive airway cilia. AICD likely occurs through the downregulation of nitric oxide (NO) and cyclic nucleotide-dependent kinases, protein kinase G (PKG) and protein kinase A (PKA). Studies by others have shown that dietary supplementation with the antioxidants N-acetylcysteine (NAC) and procysteine prevent other alcohol-induced lung complications. This led us to hypothesize that dietary supplementation with NAC or procysteine prevents AICD. To test this hypothesis, C57BL/6 mice drank an alcohol/water solution (20% w/v) ad libitum for 6 weeks and were concurrently fed dietary supplements of either NAC or procysteine. Ciliary beat frequency (CBF) was measured in mice tracheas, and PKG/PKA responsiveness to beta-agonists and NOx levels were measured from bronchoalveolar lavage (BAL) fluid. Long-term alcohol drinking reduced CBF, PKG and PKA responsiveness to beta-agonists, and lung NOx levels in BAL fluid. In contrast, alcohol-drinking mice fed NAC or procysteine sustained ciliary function and PKG and PKA responsiveness to beta-agonists. However, BAL NO levels remained low despite antioxidant supplementation. We also determined that removal of alcohol from the drinking water for as little as 1 week restored ciliary function, but not PKG and PKA responsiveness to beta-agonists. We conclude that dietary supplementation with NAC or procysteine protects against AICD. In addition, alcohol removal for 1 week restores cilia function independent of PKG and PKA activity. Our findings provide a rationale for the use of antioxidants to prevent damage to airway mucociliary functions in chronic alcohol-drinking individuals.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 19771-63-2 is helpful to your research. Application of 19771-63-2

Quantum chemical studies for some thiazolidinone derivatives using density functional theory

B3LYP/6-311G++(d, p) calculations have been carried out to study the structural and chemical properties of thioazilinone derivatives. The optimized molecular geometry of these derivative molecules are compared with the synthesized results of Mushtaque et al. The calculated results show that the density functional theory (DFT) can well reproduce the structure of the title compounds. Highest occupied-Lowest unoccupied molecular orbital (HOMO?LUMO) gap of the derivatives molecules are comparatively smaller then bare thiazolidinone. Natural bond orbital analysis for these title molecules shows strong delocalization of lone pair electrons from N, S, and O to the chemical bonds associated with central thiazolidinonering. The infrared intensites are calculated to compare with the FT-IR observation reported by Mushtaque et al. The experimental UV-Vis spectrum of present derivatives have been recorded and compared with calculated time dependent density functional (TDDFT) approach. The qualitative measures of chemical activeness of molecules have been presented in terms molecular electrostatic potential (MEP).

A phase I/II evaluation of oral L-2-oxothiazolidine-4-carboxylic acid in asymptomatic patients infected with human immunodeficiency virus

A randomized double-blind, placebo-controlled study was conducted in 37 asymptomatic HIV-infected individuals (mean CD4 count 707 cells/mm3) to characterize the safety, pharmacokinetics, and effect on blood thiols of three dosage levels of a cysteine prodrug, L-2-oxothiazolidine-4-carboxylic acid (OTC; Procysteine; Clintec Technologies, Deerfield, IL). Single-dose administration of OTC resulted in measurable plasma levels at all dosages, with a mean peak plasma concentration of 734 ± 234 nmol/mL at the highest dosage studied. After 4 weeks of administration three times daily, a statistically significant increase was seen in whole blood glutathione in the 1,500 mg and 3,000 mg dose groups compared with the placebo group. A significant increase in whole blood cysteine and peripheral blood mononuclear cell (PBMC) glutathione was not seen during the study period.

Antiinflammatory activity of triazine thiazolidinone derivatives: Molecular docking and pharmacophore modelling

Some 3-(4,6-dichloro-1,3,5-triazin-2-yl)-2-phenylthiazolidin-4-one derivatives were prepared by cyclo-condensation reaction between 2-amino-4,6-dichloro-1,3,5-triazine, substituted aromatic aldehyde and ethyl-2-mercaptoacetate, with an yield in the range 76-86 %. Prepared compounds showed antiinflammatory activity. The halogenated electron-withdrawing groups on the phenyl ring of 4-thiazolinone generated antiinflammatory activity. Among the synthesized compounds, 3-(4,6-dichloro-1,3,5-triazin-2-yl)-2-(2,5-difluorophenyl)thiazolidin-4-one showed better antiinflammatory activity with 72 and 79 % inhibition for TNF-alpha and IL-6, respectively. Also, molecular docking and pharmacophore modelling performed for this active antiinflammatory compound highlighted that hydrophobicity as an important feature for activity optimization.
