However, an effective therapeutic approach for the condition remains undiscovered. The previously proposed growth factor-based therapy has been inefficient due to its inability to pass through the blood–brain barrier. B355252, a newly developed small molecule, exhibited a potential neuroprotective effect in vivo. However, its exact efficacy in cerebral ischemia remains unclear.Methods: We adopt an endothelin-1 stereotaxic intracranial injection to induced cerebral ischemia in rat. We further conducted 2,3,5-triphenyltetrazolium chloride (TTC) staining, immunofluorescent staining, enzyme-linked immunosorbent assay (ELISA), and behavioral tests to evaluate the efficacy of B355252 in neuroprotection, anti-inflammation, and behavioral outcome improvements.Results: We identified that B355252 could protect ischemic neurons from neuronal loss by attenuating DNA damage, reducing ROS production and the LDH level, and preventing neuronal apoptosis. Moreover, inflammatory responses in astrocytic and microglial gliosis, as well as IL-1β and TNF-α levels, were ameliorated. Consequently, the behavioral outcomes of ischemic rats in neurologic responses and fore paw function recovery were improved.Discussion: Overall, our study verified the in vivo therapeutic potential of B355252. The study findings further support its application in the development of a therapeutic approach for stroke.Keywords: stroke, NGF, B355252, stroke, DNA damage, inflammation, mNSS, cylinder testWang HKChen JSHsu CYSu YTSung TCLiang CLKwan ALWu CCDove Medical Pressarticlestrokengfb355252strokedna damageinflammationmnsscylinder testPathologyRB1-214Therapeutics.
