Background

BMS-299897 is a selective inhibitor of γ-secretase with IC50 value of 12 nM [1].

γ-secretase is an intergral membrane protein whose well-known substrate is amyloid precursor protein and involves in the process of cleaving single-pass transmembrane proteins at residues with the transmembrane domain. It has been revealed thatγ-secretase cleave APP in any of multiple sites and generate a 39 to 42 amino acids long peptide, among which Aβ40 is the most common isoform and Aβ42 is the most susceptible to conformational changes leading to amyloid fibrillogenesis. Many studies have shown that reduction of brain Aβ synthesis by gamma-secretase inhibitors is a promising approach for the Alzheimer's disease treatment [1] [2].

BMS 299897 is a selective inhibitorγ-secretase. When tested HEKwt culture with BMS-299897, the expression of Aβ(1-40) in culture supernatant had a robust rise throughγ-secretase inhibition [3].

In male Swiss mice model with intracerebroventricular (i.c.v.) injection of Aβ(25-35) which induced Alzheimer's disease pathomimetic toxicity, administration of BMS-299897 markedly attenuated Aβ(1-42)-whose accumulation marginally contributed to the toxicity or long-term memory deficits-seeding and toxicity induced by Aβ(25-35) through inhibiting γ-secretase [4]. When tested with Tg2576 mice, oral administration of BMS-299897 markedly reduced Abeta peptide concentrations by inhibitingγ-secretase [5] [2].

一般建议为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。

试验操作

细胞实验 [1]:

细胞系

HEKwt培养物

制备方法

在DMSO中的溶解度大于10 mM。若配制更高浓度的溶液,一般步骤如下:请将试管置于37 °C加热10分钟和/或将其置于超声波浴中震荡一段时间。原液于-20 °C可放置数月。

反应条件

0.01 ~ 10000 nM

实验结果

在HEKwt培养物中加入BMS-299897后,γ分泌酶受抑制,Aβ-(1-40)在培养物上清液中的浓度显著增加。

动物实验 [2]:

动物模型

APP-YAC小鼠

给药剂量

1.5 ~ 150 mg/kg;口服给药

实验结果

在APP-YAC小鼠中,BMS 299897呈剂量依赖性地降低脑和血浆Aβ。

其它注意事项

请于室内测试所有化合物的溶解度。虽然化合物的实际溶解度可能与其理论值略有不同,但仍处于实验系统误差的允许范围内。
