Conantokin-G (Con-G), a 17-amino-acid peptide derived from marine snails and a potent N-methyl-D-aspartate (NMDA) antagonist, was evaluated for its neuroprotective properties in vitro and in vivo. In primary cerebellar neurons, Con-G was shown to decrease excitotoxic calcium responses to NMDA and to exhibit differential neuroprotection potencies against hypoxia/hypoglycemia-, NMDA-, glutamate-,...

Wogonin (5,7-dihydroxy-8-methoxyflavone), a flavonoid originated from the root of a medicinal herb Scutellaria baicalensis Georgi, has been previously shown to have anti-inflammatory activities in various cell types including macrophages. In this work, we have found that wogonin is a potent neuroprotector from natural source. Wogonin inhibited inflammatory activation of cultured brain microglia...

Latanoprost was first developed for use in glaucoma therapy as an ocular hypotensive agent targeting the prostaglandin F2α (FP) receptor. Subsequently, latanoprost showed a neuroprotective effect, an additional pharmacological action. However, although it is well-known that latanoprost exerts an ocular hypotensive effect via the FP receptor, it is not known whether this is also true of its neur...

background and aims: neurons are injured under physical, chemical and pathological conditions. the effect of peripheral nervous system injuries may return as retrograde to the cell body of neurons in central nervous system resulting in brain and spinal cord degeneration. because of high content of camphor and borneol, achillea biebersteinii from asteracea family may be effective in prevention t...

objective(s) the brief interruption of cerebral blood flow causes permanent brain damage and behavioral dysfunction. the hippocampus is highly vulnerable to ischemic insults, particularly the ca1 pyramidal cell layer. there is no effective pharmacological strategy for improving brain tissue damage induced by cerebral ischemia. previous studies reported that pentoxifylline (ptx) has a neuroprote...

triazine derivatives are small synthetic peptides with no apparent toxicity and high target specificity in central nervous system. hippocampal tissue is the most vulnerable area in the alzheimer’s disease (ad). the aim of this study was to investigate the neuroprotective effect of triazine in ad induced by intra-cerebro-ventricular (i.c.v.) administration of streptozotocine (stz). male wistar, ...

Objective(s): Parkinson's disease (PD) is a progressive neurological disorder associated with motor disabilities and cognitive dysfunction as well. Evidence indicates that PD occurs less frequently in women than men, confirming a role for steroid hormones in protection of dopaminergic nigrostriatal neurons. It is reported that soy genistein, an estrogen agonist phytoestrogen, display neuroprote...

Glutamate toxicity is estimated to be the key cause of photoreceptor degeneration in the pathogenesis of retinal degenerative diseases. Oxidative stress and Ca(2+) influx induced by glutamate are responsible for the apoptosis process of photoreceptor degeneration. Puerarin, a primary component of Kudzu root, has been widely used in the clinical treatment of retinal degenerative diseases in Chin...
