AbstractThe highest disability rates and mortality among neurodegenerative diseases were caused by intracerebral hemorrhage (ICH). We previously proved that Benzene, 1,2,4-trimethoxy-5-(2-methyl-1-propen-1-yl) (BTY) has an inhibitory effect on sodium ion channel and an activation effect on GABAA receptor, which were related to the brain injury. Based on this, we aimed to investigate BTY's neuroprotection on intracerebral hemorrhage and its underlying mechanism. In the in vivo study, a stereotactic injection of collagenase VII in Sprague Dawley rats (0.5 U) induced ICH and the BTY was intraperitoneally injected at 2 h after ICH. The neurological deficit scores, blood-brain barrier (BBB) permeability, and other indicators were assessed 24 h after ICH. The results showed that the BTY reduced brain edema and hematoma volume, improved neurological function and BBB permeability, and inhibited inflammatory factors and neuron apoptosis. The cell experiments proved that the BTY suppressed oxidative stress, cell apoptosis, intracellular calcium influx, and stabilized mitochondrial membrane potential by reducing glutamate's excitotoxicity. This study for the first time exhibited desirable neuroprotection of BTY, indicating it may be a promising neuroprotective agent for ICH therapy.Copyright © 2022 IBRO. Published by Elsevier Ltd.
