PRE-084

Research use only, not for human use.

PRE-084 hydrochloride is a high affinity, selective σ1 agonist.

PRE-084 hydrochloride is a high affinity, selective σ1 agonist.

PRE-084 (0.1-100 μM; 24 h) protects cultured cortical neurons against β-amyloid toxicity (maximally neuroprotective at 10 μM) and reduces the levels of proapoptotic protein Bax at 10 μM. Cell Viability AssayCell Line:Cortical cells (βAP(25-35)-induced neurotoxicity model)Concentration:0.1-100 μM Incubation Time:24 h Result:Reduced neuronal toxicity in a bell shaped-manner and is maximally neuroprotective at 10 μM.Western Blot Analysis Cell Line:Cortical cells (βAP(25-35)-induced neurotoxicity model)Concentration:10 μM Incubation Time:24 h Result:Reduced the levels of proapoptotic protein Bax in cortical neurons induced by βAP(25-35).

PRE-084 (0.25 mg/kg; i.p.; 3 times a week for 8 weeks) displays beneficial effects on motor performance (improves motor neuron survival, ameliorates paw abnormality and grip strength performance) in wobbler mice, and shows neuroprotective effects (increases the levels of BDNF in the gray matter).PRE-084 (1 mg/kg; i.p.; single) protects the heart by activating the Akt?eNOS pathway in myocardial infarction model. Animal Model:Wobbler mice (4-week-old).Dosage:0.25 mg/kg Administration:Intraperitoneal injection; 3 times a week for 8 weeks.Result:Significantly improved ameliorated paw abnormality from week 4, and notably improved paw grip strength at week 5.Reduced the number of reactive astrocytes whereas increased the number of pan-macrophage marker CD68-positive cells and CD206+ cells involved in tissue restoration.Showed 26.5% increase in the mean number of large-size NISSL-positive motor neurons.Animal Model:Adult male Sprague?Dawley rats (220-250 g; myocardial infarction model).Dosage:1 mg/kg Administration:Intraperitoneal injection; single.Result:Significantly decreased the degree of myocardial apoptosis.Led to significantly increased expression of p?Akt and p?eNOS.
