Stroke-prone spontaneously hypertensive rats (SHRSP) were treated with food admixed, 6,7-dimethoxy-1-(3,4-dimethoxybenzyl)-4-([4-(2-methoxyphenyl)-1- piperazinyl]methyl)isoquinoline (Ro 22-4839), a novel cerebral circulation improver, for a period of 15 weeks starting from 5 weeks of age at an
A series of isoquinoline-1,3,4-trione derivatives were identified as novel and potent inhibitors of caspase-3 through structural modification of the original compound from high-throughput screening. Various analogues (2, 6, 9, 13, and 14) were synthesized and identified as caspase inhibitors, and
OBJECTIVE
Berberine is a type of isoquinoline alkaloid that has been used to treat various diseases. A neuroprotective effect of berberine against cerebral ischemia has been reported; however, the effects of berberine on apoptosis in relation to reactive astrogliosis and microglia activation under
OBJECTIVE
The mechanism underlying forced limb-use -induced structural plasticity remains to be studied. We examined whether the cyclic adenosine monophosphate (cAMP)-mediated signal transduction pathway was involved in brain plasticity and promoted behavioral recovery induced by forced limb-use
NC 7197, a new N-substituted tetrahydroisoquinoline derivative, was given in doses of 0.2 mg/kg body weight on 26 occasions to a series of 23 critically ill postoperative and posttraumatic patients who had been in moderate or severe degrees of shock. This agent was observed to improve pressure-flow
Vascular thrombosis is a major risk of the onset of stroke and so novel therapeutic candidates have been attracting interest. In this context, here docking based computer assisted screening and mesoscale simulation were used to design
Activation of the RhoA/Rho-kinase (ROCK) pathway induces endothelial barrier dysfunction and increased vascular permeability, which is a hallmark of various life-threatening vascular pathologies. Therapeutic approaches aimed at inhibiting the RhoA/ROCK pathway have proven effective in the
Berberine, an isoquinoline alkaloid extracted from medicinal herbs, has been used as antipyretic, antidiarrheal, bactericide and anti-inflammatory agent. In this study, berberine effects on neuronal damage have been examined. The right carotid artery of seven-day-old rat pups was ligated (ischemic
During the past years a number of potent and selective antagonists for the human A(3) adenosine receptor (AR) have been developed, including tricyclic compounds, such as triazoloquinazoline, pyrazolo-triazolopyridine, imidazopurinone, triazoloquinoxaline and pyrazoloquinoline derivatives. Bicyclic
Protection of both grey and white matter is important for improvement in stroke outcome. In the present study the ability of a competitive alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) antagonist to protect axons, oligodendrocytes, and neuronal perikarya, was examined in a rodent
3,4-Dihydro-3,3-dimethyl-isoquinoline-2-oxide (MDL 101,002) is a conformationally constrained cyclic analog of the known spin trap alpha-phenyl N-tert-butyl nitrone (PBN). Because of PBN's ability to scavenge free radicals, MDL 101,002 is currently being evaluated in stroke models as a means to
The platelet aggregation is a crucial step in a pathophisiology of thromboses, leading to development of cardio-vascular diseases (myocardial infarction, transient ischemic attacks, strokes, etc.). The final step in the aggregation is the binding of fibrinogen to receptor - glycoprotein IIb/IIIa (GP
OBJECTIVE
Neurodegenerative diseases have been associated with glutamatergic dysfunction. Berberine, an isoquinoline alkaloid broadly present in different medicinal herbs, has been reported to have neuroprotective effect. In the present study, the effects of berberine against glutamate-induced
Overexpression of the translocator protein, TSPO (18 kDa), formerly known as the peripheral benzodiazepine receptor, is a hallmark of activation of cells of monocytic lineage (microglia and macrophages) during neuroinflammation. Radiolabeling of TSPO ligands enables the detection of
METHODS
Existing research indicates that anti-inflammatory and antioxidant properties of berberine play major roles in coping with oxidative stress in neurodegenerative diseases, but it is not known if this isoquinoline alkaloid affects inflammatory cytokines such as interleukin 10 in focal cerebral
