SKF 83959 hydrobromide

SKF83959 hydrobromide is a potent and selective dopamine D1-like receptor partial agonist. SKF83959 hydrobromide Ki values for rat D1, D5, D2 and D3 receptors are 1.18, 7.56, 920 and 399 nM, respectively. SKF83959 hydrobromide is a potent allosteric modulator of sigma (σ)-1 receptor. SKF83959 hydrobromide belongs to benzazepine family and has improvements on cognitive dysfunction. SKF83959 hydrobromide can be used for the research of Alzheimer's disease and depression[1][2][3][4].

SKF83959 hydrobromide (10~250 μM) stimulates PIP2 hydrolysis in membranes. SKF83959 hydrobromide (0.1~10 μM; PC12 cell) changes the EC50 value of SKF81297 from 0.5 nM in control tissue to 31.6 nM, 251.2 nM and 631.0 nM[2].

SKF83959 hydrobromide (0.5 and 1 mg/kg; i.p.; 1 hour) reverses the scopolamine-induced cognitive impairments in the passive avoidance task and Y-Maze test[1]. SKF83959 hydrobromide (1 mg/kg; i.p.; 30 minutes) induced memory enhancing effects are prevented by brain-derived neurotrophic factor system blockade[1]. SKF83959 hydrobromide has anti-amnesic activities and restores the scopolamine-decreased BDNF signaling pathway in the hippocampus in mice[1]. Animal Model: Male ICR male mice (8 weeks)[1] Dosage: 0.5 and 1 mg/kg Administration: I.p.; 1 hour Result: Reversed the scopolamine-induced cognitive impairments in the passive avoidance task and Y-Maze test. Animal Model: Male ICR male mice (8 weeks)[1] Dosage: 1 mg/kg Administration: I.p.; 30 minutes Result: The memory enhancing effects were prevented by BDNF system blockade.
