Description

Avagacestat (BMS-708163) is a potent inhibitor of γ-secretase, with IC50s of 0.27 nM and 0.30 nM for Aβ42 and Aβ40 inhibition; Avagacestat (BMS-708163) also inhibits NICD (Notch IntraCellular Domain) with IC50 of 0.84 nM and shows weak inhibition of CYP2C19, with IC50 of 20 μM. Avagacestat can be used for Alzheimer disease research.

IC50 & Target

IC50: 0.27 nM (γ-secretase, Aβ42), 0.30 nM (γ-secretase, Aβ40), 20 μM (CYP2C19)[1], 0.84 nM (NICD)[2]

In Vitro

Avagacestat (BMS-708163) exhibits weaker potency for inhibition of Notch processing, IC50=58±23 nM, as compared to its inhibition potency for APP cleavage[1]. Avagacestat (BMS-708163) (10 µM) combined with gefitinib significantly attenuates the colony growth of PC9/AB2 cells, increases the expression of active caspase 3 and PARP and reduces the expression of Ki-67 in PC9/AB2 cells. Avagacestat (BMS-708163) induces apoptosis and enhances cell cycle arrest at the G1 phase in PC9/AB2 cells. Avagacestat (BMS-708163) treatment effectively downregulates the expression of Notch1, HES1, PI3K and Akt in PC9/AB2 cells[3].

In Vivo

Avagacestat (BMS-708163) significantly reduces both plasma and brain Aβ40 levels relative to control at 10 and 100 mg/kg for the entire dosing interval, demonstrates significant Aβ40 lowering for 8 h after an oral dose of 1 mg/kg, and significantly lowers CSF Aβ40 levels in rats, when measured 5 h after single oral doses ranging from 3 to 100 mg/kg[1]. Avagacestat (BMS-708163) (10 mg/kg) monotherapy has a minor inhibitory effect on PC9/AB2 tumor growth compared with gefitinib alone. BMS-708163 monotherapy results in a slight increase in caspase 3 expression as well as a mild decrease in Ki-67 expression in vivo. In the xenograft lung cancer samples treated with Avagacestat (BMS-708163) plus gefitinib, there are a marked increase in caspase 3 expression and a reduction in Ki-67 staining[3].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 3 mg/mL (5.76 mM); Clear solution

    This protocol yields a clear solution of ≥ 3 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (30.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Cell Assay
[3]

The cell viability is assessed using a tetrazolium salt (WST-8)-based colorimetric assay from the Cell Counting Kit 8 (CCK-8). The cells are seeded into 96-well plates at an initial density of 5×103 cells/well and cultured for 24 h, after which the cells are cultured with DMSO, increased concentrations of gefitinib or Avagacestat (BMS-708163) , BIBW2992, or the combination of Avagacestat (BMS-708163) and BIBW2992 for an additional 48 h. The A450 is measured in a microplate reader after 10 µL of CCK-8 solution is added and incubated for 1 h. The percentage of growth is shown relative to untreated controls.

Animal Administration
[3]

Four- to six-week-old female Balb/c athymic (nu + /nu +) mice are anesthetized with ether. The mice are acclimatized for one week before being injected with 1.5×106 PC9/AB2 cells that have been resuspended in 200 μL of matrigel. When established tumors of approximately 150-300 mm3 in diameter are detected, the mice are randomly divided into groups and fed orally by gavage with either vehicle (1% methylcellulose, 0.2% Tween 80 in sterilized water), gefitinib (3 mg/kg diluted in vehicle), Avagacestat (BMS-708163) (10 mg/kg diluted in vehicle), or a combination of gefitinib (3 mg/kg) and Avagacestat (BMS-708163) (10 mg/kg) for 5 days/week. Each treatment group consists of eight mice. The tumor volume are measured and calculated every five days using the following formula: π/6×(larger diameter)×(smaller diameter)2. After 30 days, mice are killed by cervical dislocation.

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.
