Seltzer model of neuropathic painAcute thermal nociception [62]
Freund’s adjuvant (CFA) pain modelModerate effect in inflammatory pain and edema
BBG toxicity assays in Drosophila melanogasterNo impairment on survival of the insect model (LC50 = 38 mM). No neurotoxic effects[63]
Suppression of P2X7R-induced ganglion cell death[64]
Protective neuronal effects upon oxygen-glucose deprivationThe brain damaged area following ischemia was diminished in the animals pretreated with BBG, compared to treatment with vehicle alone[67]
Cerebral ischemia/reperfusion (I/R) injuryBBG (10 μg) protected against transient global cerebral I/R injury, augmented survival rates, retarded I/R-induced learning and memory deficits, and suppressed I/R-induced neuronal death, DNA cleavage, glial activation and inflammatory cytokine overexpression in the hippocampus[68]
Traumatic brain injury (TBI) induced by posterior cerebral edemaBBG (25 mg/kg) orally administered before the TBI induction diminished the TBI effects[69]
Duchenne muscular dystrophy (mdx/mdx mouse)BBG treatment recovered the CD62L in blood lymphocytes and it maintained its ability to migrate to the heart[71]
Treatment with BBG impaired the number of degeneration-regeneration cycles in mdx skeletal muscles in vivo[72]
Agglomeration of pathogenic prion protein (PrPres)Diminished number of PrPres in infected mouse brain after the administration of BBG[73]
