Of the major components of the kynurenine pathway for the oxidative metabolism of tryptophan, most attention has focussed on the N-methyl-D-aspartate (NMDA) receptor agonist quinolinic acid, and the glutamate receptor blocker kynurenic acid. However, there is increasing evidence that the redox-active compound 3-hydroxyanthranilic acid may also have potent… (More)
Angiogenesis represents a form of neovascularisation of exceptional importance in numerous pathological conditions including stroke. In this context it is directly related to neuroregeneration which is seen in close proximity. However, numerous experimental data have been drawn from studies that have ignored the age criterion. This is extremely important as… (More)
Others imitate paper (Word, Acrobat) and the constant 3D world we live in ("Virtual Reality"). Our system instead tries to create documents better than paper in a space better than reality.
We report two series of novel cephalosporins that are bactericidal to Mycobacterium tuberculosis alone of the pathogens tested, which only kill M. tuberculosis when its replication is halted by conditions resembling those believed to pertain in the host, and whose bactericidal activity is not dependent upon or enhanced by clavulanate, a β-lactamase… (More)
Venezuelan equine encephalitis virus (VEEV) is an emerging pathogenic alphavirus that can cause significant disease in humans. Given the absence of therapeutic options available and the significance of VEEV as a weaponized agent, an optimization effort was initiated around a quinazolinone screening hit 1 with promising cellular antiviral activity (EC 50 =… (More)
