Cysteine-dependant aspartyl protease (caspase) activation has been implicated as a part of the signal transduction pathway leading to apoptosis. It has been postulated that caspase-3 inhibition could attenuate cell damage after an ischemic event and thereby providing for a novel neuroprotective
A series of novel 3-(furo[2,3-b]pyridin-3-yl)-4-(1H-indol-3-yl)-maleimides were designed, synthesized, and biologically evaluated for their GSK-3β inhibitory activities. Most compounds showed favorable inhibitory activities against GSK-3β protein. Among them, compounds 5n, 5o, and 5p significantly
A series of novel 3-([1,2,4]triazolo[4,3-a]pyridin-3-yl)-4-(indol-3-yl)-maleimides were designed, prepared and evaluated for their GSK-3β inhibitory activities. Most compounds showed high potency to GSK-3β inhibition with high selectivity. Among them, compounds 7c, 7f, 7h, 7l and 7m significantly
The 5-lipoxygenase-activating protein (FLAP) gene and an increase in leukotriene (LT) production are linked to the risk of asthma, myocardial infarction, and stroke. We evaluated the pharmacodynamics, pharmacokinetics, and tolerability of
Evidence is increasing that therapeutic modulation of neurohormonal activation with vasopressin receptor antagonists via V(1A) and V(2) receptors may favourably affect prognosis of heart failure. This study was designed to compare in vivo hemodynamic effects of early treatment (1-21 days after
A series of 3-aryloxindole derivatives were synthesized and evaluated as activators of the cloned maxi-K channel mSlo expressed in Xenopus laevis oocytes using electrophysiological methods. The most promising maxi-K openers to emerge from this study were
The racemate 1, ((+/-)-(5-Chloro-2-methoxyphenyl)-1,3-dihydro-3-fluoro-6-(trifluoromethyl)- 2H-indol-2-one), is a potent, specific and novel opener of cloned large-conductance, calcium-activated (maxi-K) potassium channels. One of its enantiomers, BMS-204352 (MaxiPost), is undergoing clinical
Neuropeptides are the most abundant chemical messengers in the brain and their major role seems to be the modulation of amine and amino acid neurotransmission. This appears to be achieved at many sites by the co-release of peptide with the primary transmitter. The presynaptic biochemistry and
Atherosclerotic plaques can lead to partial vascular occlusions that produce abnormally high levels of arterial wall shear stress. Such pathophysiological shear stress can promote shear-induced platelet aggregation (SIPA), which has been linked to acute myocardial infarction, unstable angina, and
Mitochondria are key organelles implicated in a variety of processes related to energy and free radical generation, the regulation of apoptosis, and various signaling pathways. Mitochondrial dysfunction increases cellular oxidative stress and depletes ATP in a variety of inherited mitochondrial
N-[2-(5-hydroxy-1H-indol-3-yl) ethyl]-2-oxopiperidine-3-carboxamide (HIOC), an N-acetyl serotonin derivative, selectively activates tropomyosin-related kinase receptor B (TrkB). This study is to investigate a potential role of HIOC on ameliorating early brain injury after experimental subarachnoid
