Post-stroke

The quinuclidine PHA 568487 free base is an agonist of the alpha 7 nicotinic acetylcholine receptor that was designed to mitigate the bioactivation associated with the core scaffold and subsequently remove associated liabilities with in vivo tolerability.

N-Acetyl lysyltyrosylcysteine amide is a non-toxic, potent, reversible, and specific myeloperoxidase (MPO) tripeptide inhibitor that effectively inhibits MPO production in vivo, attenuates neuronal damage, preserves brain tissue and neurological function post-stroke, and inhibits MPO-dependent hypochlorite (HOCl) production, protein nitration, and LDL oxidation. It is also used in the study of bronchial dysplasia.

TAT-NEP1-40, a blood-brain barrier (BBB) permeable peptide, confers protection to PC12 cells against oxygen and glucose deprivation (OGD) while promoting neurite outgrowth. Furthermore, it enhances neurologic outcomes post-ischemia by mitigating apoptosis in affected cerebral regions. This compound holds potential for central nervous system (CNS) injury research, including studies on axonal regeneration and post-stroke functional recovery [1].

TAT-NEP1-40 TFA, a blood-brain barrier-permeable peptide, safeguards PC12 cells against oxygen and glucose deprivation (OGD) and fosters neurite outgrowth. Additionally, it enhances neurological outcomes post-ischemia by curtailing apoptosis in ischemic cerebral tissues. This compound has utility in investigating central nervous system (CNS) injuries, encompassing axonal regeneration and functional recuperation following a stroke [1].

TAT-NEP1-40 acetate, a potential therapeutic for axonal regeneration and functional recovery post-stroke, safeguards PC12 cells from oxygen and glucose deprivation (OGD) and encourages neurite outgrowth. This compound also affords cerebral protection against ischemia reperfusion injury by hindering neuronal apoptosis and can be effectively administered into rat brains [1] [2].

Tat-M2NX, a peptide antagonist of transient receptor potential melastatin 2 (TRPM2), blocks hydrogen peroxide-induced calcium influx in HEK293 cells expressing human TRPM2 at concentrations between 25 to 100 µM. In male mice models of stroke caused by middle cerebral artery occlusion (MCAO), Tat-M2NX (20 mg/kg) demonstrates efficacy in reducing brain infarct volume when applied before or 3 hours-post occlusion, yet it shows no such effect in female mice.
