产品描述 | Safinamide mesylate (EMD 1195686 mesylate) , a mesylate salt of Safinamide, can reversibly and specifically inhibit MAO-B (IC50: 98 nM), has 5918-fold selectivity against MAO-A. |
靶点活性 | MAO-B:98 nM |
体外活性 | Safinamide is a highly specific MAO-B inhibitor in rat brain mitochondria (IC50: 98 nM) and also inhibits MAO-B in human brain (IC50: 9 nM). Safinamide has a high affinity for the Na+ channel-binding site II in rat cortical membranes (IC50: 8 μM). Safinamide concentration- and state-dependently inhibits the fast Na+ currents in rat cortical neurons. Safinamide blocks N-Type Ca2+ currents in rat cortical neurons (IC50: 23 μM). Safinamide inhibits glutamate release induced by depolarizing conditions in rat hippocampal synaptosomes (IC50: 9 μM). Safinamide ( IC50: 1.4 μM) incubated 1 hour before veratridine reduces the neuron damage through blockade of opening voltage-dependent Na+ and Ca2+ channels in rat primary cortical neurons. Safinamide binds to human MAO-B (Ki: 0.5 μM). Safinamide binds to human MAO-B in an extended conformation occupying both flavin and entrance cavity. |
体内活性 | Safinamide (p.o.) dose-dependently inhibits mouse brain MAO-B (IC50: 0.6 mg/kg), and MAO-B activity recovers quickly, starting from 8 hours. Safinamide markedly inhibits cell body degeneration in the substantia nigra pars compacta. Safinamide intraperitoneally administered 15 minutes before kainic acid protects against hippocampal neuron loss, starting at 10 mg/kg showing neuroprotective properties. Safinamide (100 mg/kg, i.p.) shows a relevant neuro rescuing effect on hippocampal neurons when given 3 hours after ischemia. Safinamide has a high oral bioavailability (80-92%), is rapidly absorbed in plasma after reaching the peak within 0.5-2 hours declines, with a terminal half-life of about 3, 7, and 13 hours in mice, rats, and monkeys, respectively. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
