Diindolylmethane Ameliorates Ischemic Stroke-Induced Brain Injury by Peripheral and Central Mechanisms
CONCLUSION: This inhibition of platelet aggregation, platelet mediated oxidative stress, and inflammation, improved blood flow, and reduced neurological deficits, brain infarction, BBB leakage, brain water content, and histopathological abnormalities indicate the preservation of brain structural integrity. Therefore, these findings conclude that DIM exhibits neuroprotection by inhibiting platelet aggregation. Thus, the present study provided preclinical evidence of DIM neuroprotection against ischemic stroke.PMID:36397630 | DOI:10.2174/1567202620666221116161128

A Polyphenolic Complex Attenuates Inflammatory Response and Blood-Brain Barrier Disruption.
Abstract BACKGROUND: Cerebral ischemia causes strong inflammatory response. Neumentix is a dietary supplement containing 14.9% rosmarinic acid and 29.9% total phenolic content, which was proved to be beneficial against inflammatory response. Therefore, we investigated Neumentix's effect on anti-inflammatory and blood brain barrier (BBB) disruption in transient middle cerebral artery occlusion (tMCAO) model mice. METHODS: After the pretreatment of vehicle or Neumentix 134 mg/kg/d, intraperitoneal injection (i.p.) (containing rosmarinic acid 20mg/kg/d) for 14 days, mice were subjected to tMCAO for 60 min and ke...

Artificial Hibernation by Phenothiazines: A Potential Neuroprotective Therapy Against Cerebral Inflammation in Stroke.
CONCLUSION: This study showed an inhibitory effect of C+P on brain inflammation, which may be partially dependent on drug-induced hibernation, as well as other mechanisms of action by these drugs. These findings further suggest the great potential of C+P in the clinical treatment of ischemic stroke. PMID: 31232236 [PubMed - as supplied by publisher]

The 5-lipoxygenase (5-LOX) inhibitor zileuton reduces inflammation and infarct size with improvement in neurological outcome following cerebral ischemia.
The objective of this study was to evaluate the effects of blocking 5-LOX activity in a murine model of transient and global brain ischemia. Zileuton improved neurological deficits and significantly decrease volume and density of lesion, compared to vehicle-ischemic animals measured by magnetic resonance imaging (MRI). In addition, the blockage of 5-LOX reduced infarct area and histopathological changes. Furthermore, by enzyme immunoassay (ELISA) increased brain levels of tumor necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma), interleukin-1beta (IL-1beta), interleukin-6 (IL-6), chemokine (C-X-C motif) ligand...
