    ARS-1620 purchased from MCE. Usage Cited in: Cell Death Discov. 2023 Feb 6;9(1):45.  [Abstract]

    In MIA PaCa-2 cells, ARS-1620 (10 µM; 48 h) limites Gemcitabine (10 µM)-induced ERK phosphorylation and autophagy flux, thus reinforcing the contribution of the RAS–ERK pathway in Gemcitabine-induced autophagy.

    生物活性

    ARS-1620 is an atropisomeric selective KRASG12C inhibitor with desirable pharmacokinetics.

    IC50 & Target[1]

    KRAS(G12C)

     

    体外研究
    (In Vitro)

    ARS-1620 is an atropisomeric selective KRASG12C inhibitor with desirable pharmacokinetics. ARS-1620 exhibits complete growth suppression of p.G12C cell lines (IC50=150 nM) with relatively benign effects on control cell lines. It is found that ARS-1620 significantly reduces expression of the gene set in p.G12C mutant cells in a time-dependent manner but not in the p.G12S mutant cells. Following a 5-day treatment period, only a minority of G12C mutant cell lines are sensitive to ARS-1620 under monolayer culture conditions, whereas in 3D-spheroid conditions, ARS-1620 elicits a robust response (p=0.0140)[1].

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

    体内研究
    (In Vivo)

    Following a single oral dose or 5 consecutive daily doses, ARS-1620 yields average peak tumor concentrations of 1.5 μM (50 mg/kg) and 5.5 μM (200 mg/kg), respectively, that enables significant KRASG12C target occupancy (>=70% G12C-TE at 200 mg/kg) for >24 hr. In MIAPaCa2 xenografts (p.G12C), ARS-1620 significantly inhibits tumor growth (p<0.001) in a dose-dependent manner with marked regression at a dose of 200 mg/kg, given once daily. Across all tumor models employed, ARS-1620 is well tolerated over the entire 3-week treatment period. Moreover, there are no observed clinical signs or toxicity of ARS-1620 in CD-1 mice even at oral doses up to 1,000 mg/kg administered daily over a 7-day period.

    Cell Assay
    [1]

    5×104 cells are seeded into 24 well ULA-plates and allowed to rest overnight. Cells are then treated with DMSO or ARS-1620. After 2 days of treatment, apoptosis and cell death is measured by staining with annexinV-APC and prodidium iodide or by 70% ethanol fixation followed by FxCycle Violet staining to measure DNA content (cell cycle) and percentage of sub-diploid events by flow cytometry[1].

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

    Animal Administration
    [1]

    For pharmacokinetic (PK) studies 6- to 8-week-old male BALB/c mice are used. To determine oral bioavailability, mice are treated with ARS-1620 by a single intravenous (IV) bolus or oral gavage administration at the doses of 2 and 10 mg/kg, respectively. ARS-1620 concentration in plasma is quantified by LC-MS/MS-based methods. Pharmacokinetic parameters are estimated from mean plasma concentration-time profiles. The area under the curve (AUC) is calculated from time versus concentration data using the linear trapezoidal rule. The oral bioavailability is calculated as the ratio of AUC for ARS-1620 from oral and IV dosage. The calculation is normalized by relative doses[1].

    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.
