    生物活性

    DAPT (GSI-IX) is a potent and orally active γ-secretase inhibitor with IC50s of 115 nM and 200 nM for total amyloid-β (Aβ) and 42, respectively. DAPT inhibits the activation of Notch 1 signaling and induces cell differentiation. DAPT also induces autophagy and apoptosis. DAPT has neuroprotection activity and has the potential for autoimmune and lymphoproliferative diseases, degenerative disease and cancers treatment[1][2].

    IC50 & Target

    IC50: 115 nM (Aβ), 200 nM (Aβ42)[5]

    体外研究
    (In Vitro)

    DAPT 抑制 Aβ 的产生超过 90%,仅适度降低培养基中的 APPβ。尽管 DAPT 处理后 APPβ 减少了约 30%,但这种作用不依赖于浓度,并且可以通过去除 DAPT 来逆转[1]
    DAPT 的浓度 (0、25、50 和 75 μM) 和 γ-分泌酶产生的 Notch 1 片段 Val1744-NICD 在 48 小时后以剂量依赖性方式降低 (P <0.01)。在 50 μM 浓度下,γ-分泌酶的激活几乎完全被 DAPT 抑制[3]

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    体内研究
    (In Vivo)

    将 DAPT 施用于 PDAPP 小鼠 (100 mg/kg sc),并检查大脑皮层中的 DAPT 和 Aβ 水平。处理后 3 小时大脑中达到 490 ng/g 的峰值 DAPT 水平,并且在前 18 小时内持续超过 100 ng/g (~200 nM) 的水平。这些 DAPT 的脑浓度超过了其降低神经元培养物中 Aβ 的 IC50 (115 nM),并产生了稳健和持续的药效学效应[1]
    DAPT 通过下调大鼠Notch 1和核因子kappa B的表达来保护大脑免受脑缺血。Western blot 分析还显示,DAPT (0.03 mg/kg) 组 Notch 1 和 NF-κB 表达显著降低 (P<0.05 vs. MCAO 组)[2]

    Cell Assay
    [1]

    Human embryonic kidney cells, transfected with the gene for APP751 (HEK 293) are used for routine Aβ reduction assays. Cells are plated in 96-well plates and allowed to adhere overnight in Dulbecco's modified Eagle medium (DMEM) supplemented with 10% heat-inactivated fetal bovine serum. Cells are pre-treated for 2 h at 37°C with DAPT (0, 0.4, 2, 10, 50 and 250 nM), media are aspirated off and fresh compound solutions applied. After an additional 2-h treatment period, conditioned media are drawn off and analyzed by a sandwich ELISA (266-3D6) specific for total Aβ. Reduction of Aβ production is measured relative to control cells treated with 0.1% DMSO and expressed as a percentage inhibition. Data from at least six doses in duplicate are fitted to a four-parameter logistical model using XLfit software in order to determine potency[1].

    Animal Administration
    [1][3]

    Mice[1]
    The three- to four-month-old heterozygous PDAPP transgenic mice overexpressing the APPV717F mutant form of the amyloid precursor protein. Each treatment group (n=10) consists of equal numbers of age-matched male and female animals that are fasted overnight prior to treatment. Both treatment and control groups are dosed at a volume of 10 mL/kg with DAPT or vehicle alone. Tissues are processed and all Aβ and APP measurements are made. After removal of the brain, the cortex from one hemisphere is homogenized, centrifuged, and the supernatant is used for Aβ measurements. Cortex from the other hemisphere is snap frozen for analysis of compound levels. Aβ levels are expressed as ng/g of wet tissue weight, and percentage reductions are calculated relative to the mean Aβ level of tissue from vehicle-treated control animals. Data are analyzed with Mann-Whitney non-parametric statistics to assess significance.
    Rats[3]
    Male Sprague-Dawley rats (260-290 g) are used. DAPT solution is stereotactically injected into the lateral cerebral ventricle (LV) immediately after MCAO. The stereotactic injections into the LVs are performed at coordinates −0.8 mm anteroposterior, ±1.5 mm mediolateral and −4.5 mm dorsoventral from the bregma. 30 rats are randomly assigned to three operating groups (10 rats in each group): sham-operated group that receive equal volume of PBS without MCAO operation; MCAO group that receive equal volume PBS after MCAO (MCAO); and DAPT group that receive DAPT as 0.03 mg/kg after MCAO. 24 h after operation the first neurological function is assessed and then 48 h after operation the second neurological function is assessed. Meanwhile, brain water content and infarction volume are measured and compared among different groups.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
