| 产品简介: | 一种与拉曲匹定(DMEBON)有关的药物,它具有神经保护和促神经原作用。 P7C3 is a drug related to latrepirdine (dimebon), which has neuroprotective and proneurogenic effects, and may be potentially useful for the treatment of Alzheimer's disease and similar neurodegenerative disorders. The precise mechanism of action through which these effects are exerted remains unclear as of 2010, but the pharmacological effects of P7C3 in vitro resemble those of endogenous proneurogenic peptides such as fibroblast growth factor 1, and the proneurogenic activity of P7C3 was around thirty times that of dimebon when they were compared side by side in mice. P7C3 was chosen for further animal studies on the basis of favourable pharmacokinetic factors, such as its high oral bioavailability and long duration of action, but several other related compounds showed similar activity such as the more potent fluorinated analogue P7C3A20 which is up to ten times stronger again, and the methoxy analogue P7C3-OMe, for which it was determined that the (R) enantiomer is the active form. |
| 溶解性: | 溶于DMSO |
| 储备液保存: | -80°C, 2 years; -20°C, 1 year。 |
| 体内实验: | 1、请依序添加每种溶剂: 10% DMSO→40% PEG300→5% Tween-80→45% Saline Solubility: ≥ 3.85 mg/mL (7.61 mM); 澄清溶液 此方案可获得 ≥ 3.85 mg/mL(饱和度未知)的澄清溶液。 以 1 mL 工作液为例,取 100 μL 38.5 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL。 2、请依序添加每种溶剂: 10% DMSO→90% Corn Oil Solubility: ≥ 2.5 mg/mL (4.94 mM); 澄清溶液 此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液,此方案实验周期在半个月以上的动物实验酌情使用。 以1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 玉米油中,混合均匀。 <1mg/ml表示微溶或不溶。 普西唐提供的所有化合物浓度为内部测试所得,实际溶液度可能与公布值有所偏差,属于正常的批间细微差异现象。 请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液;一旦配成溶液,请分装保存,避免反复冻融造成的产品失效。 |
| 体外研究: | P7C3-A20 (10-100 μM; 8 hours; PC12 cells) 处理可减轻 PC12 细胞中氧-葡萄糖剥夺(OGD) 诱导的细胞毒性。 P7C3-A20 (40-100 μM; 8 hours; PC12 cells) 处理可减轻 OGD 诱导的 PC12 细胞凋亡。 |
| 体内研究: | P7C3-A20 (5-10mg/kg; intraperitoneal injection; daily; for 7 days; Sprague-Dawley rats) 可减少梗塞体积;在 HI 模型大鼠中逆转皮质和海马体中的细胞损失并改善运动功能而不引起神经毒性。P7C3-A20 通过激活 PI3K/AKT/GSK3β 信号通路防止 HI 诱导的神经元损伤。 |
| 保存条件: | -20℃ |
| 注意事项: | 1、为了您的安全和健康,请穿实验服并戴一次性手套操作。 2、以上信息仅做参考交流之用。 |
