Density functional theory (DFT) based calculations have been performed to examine the relaxations of tautomers of 4–hydroxy–6–methylpyridin–2(1H)–one (MPO), as a representative of pyridinone derivatives, at the fullerene (C60) surfaces. Optimized molecular properties including energies, dipole moments and atomic scale quadrupole coupling constants (CQ) have been e...

The classical method of quantitative structure-activity relationships (QSAR) is enriched using non-linear models, as Thom's polynomials allow either uni- or bi-variate structural parameters. In this context, catastrophe QSAR algorithms are applied to the anti-HIV-1 activity of pyridinone derivatives. This requires calculation of the so-called relative statistical power and of its minimum princi...

Signal transduction through the p38 mitogen-activated protein (MAP) kinase pathway is central to the transcriptional and translational control of cytokine and inflammatory mediator production. p38 MAP kinase inhibition hence constitutes a promising therapeutic strategy for treatment of chronic inflammatory diseases, based upon its potential to inhibit key pathways driving the inflammatory and d...

Brain iron accumulation has been associated with inciting the generation of oxidative stress in a host of chronic neurological diseases, including Parkinson's disease. Using the catecholaminergic neurotoxin 6-hydroxydopamine to lesion cellular dopaminergic pathways as a model of Parkinson's disease in culture, a selection of 1-hydroxypyridin-2-one (1,2-HOPO) metal chelators were synthesized and...

A number of 1,3,4-oxadiazole, 3-9, and 1,2,4-triazole derivatives, 13-15, were synthesized starting form the acid hydrazide 1. The 1,3,4-thiadiazole derivative 12 was prepared from the substituted phenylthiosemicarbazide derivative 11 by treatment with sulfuric acid. The aryl hydrazone derivatives 10a-c were synthesized by reaction of the hydrazide 1 with the corresponding ketones. The thioalky...
