体内实验:
1、请依序添加每种溶剂: 10% DMSO→40% PEG300→5% Tween-80→45% Saline
Solubility: ≥ 2.5 mg/mL (4.88 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。
以 1 mL 工作液为例,取 100 μL 25.0 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。
<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。

靶点:
IC50: 7 nM (Aβ, in HEK293 cells)
体外研究:
BMS-299897 reduces the levels of each of the Aβ peptides. At 1 μM, BMS-299897 decreases these peptides to levels ranging from 20 to 50% of the vehicle control. BMS-299897 treatment reduces the portion of QD-BDNF signals moving in the retrograde direction (p=0.0198) with a concomitant increase in the portion of signals moving in the anterograde direction (p=0.0147).
体内研究:
BMS-299897 shows dose- and time-dependent reductions of amyloid β-peptide (Aβ) in brain, cerebrospinal fluid (CSF), and plasma in young transgenic mice, with a correlation between brain and CSF Aβ levels. BMS-299897 reduces both brain and plasma Aβ1-40 in APP-YAC mice and increases brain concentrations of APPcarboxy-terminal fragments, consistent with γ-secretase inhibition. BMS-299897, attenuates this Aβ25-35-induced Aβ1-42 seeding and toxicity. BMS-299897 is administered at 0.1-1 nmol/mouse, concomittantly with Aβ25-35 (9 nmol) in male Swiss mice. After one week, the contents in Aβ1-42 and Aβ1-40, and the levels in lipid peroxidation are analyzed in the mouse hippocampus. Mice are submitted to spontaneous alternation, passive avoidance and object recognition to analyze their short- and long-term memory abilities. Aβ25-35 increases Aβ1-42 content (+240%) but fails to affect Aβ1-40. BMS-299897 blocks the increase in Aβ1-42 content and decreased Aβ1-40 levels significantly. The compound does not affect Aβ25-35-induced increase in hippocampal lipid peroxidation. Behaviorally, BMS-299897 blocks the Aβ25-35-induced deficits in spontaneous alternation or novel object recognition, using a 1 h intertrial time interval. The co-administration of the γ-secretase inhibitor BMS-299897, in the 0.1-1 μmol/mouse dose-range, completely blocks the Aβ25-35-induced increase in Aβ1-42 content.
