In Vitro

In the UACC-62 tumor cell line assay, SAR-260301 inhibits pAktS473 with a measured IC50 at 0.06 μM and an estimated IC90 at 2 μM[1]. In MEF-3T3-myr-p110β mechanistic model, SAR260301 inhibits PI3Kβ-dependent proliferation/viability in low serum conditions with an IC50 of 196 nM. In PTEN-deficient human prostate tumor cells, SAR260301 inhibits LNCaP cell proliferation in low and high serum conditions with IC50 values of 2.9 and 5.0 μM, respectively, after 4-day treatment, whereas it is inactive in these conditions in PC3 cells at concentrations up to 10 μM, despite target engagement. After prolonged treatment, SAR260301 at 3 or 10 μM inhibits PC3 cell proliferation in low serum conditions, with a cytostatic effect achieved for 14 days, despite some cell death induction observed at 10 μM. SAR260301 also leads to antitumor activities in PTEN-deficient/BRAF-mutant human melanoma cells, inhibiting cell proliferation with IC40 values of 6.5 and 3.3 μM for UACC-62 and WM-266.4, respectively, after 4-day treatment[2].

In Vivo

SAR-260301 displays antitumor efficacy in human PTEN-deficient melanoma models in mice as a single agent. SAR-260301 treatment leads to a statistically significant tumor growth inhibition as measured by a ΔT/ΔC of 39% (p = 0.054 versus control mice) on day 15 post-tumor implantation. SAR-260301 is well tolerated at the active dose, with no sign of toxicity and no body weight loss. Oral administration of SAR-260301 reveals sustained target inhibition (≥50%) of pAkt-S473 for at least 7 h. SAR-260301 has moderate terminal elimination half-life (t1/2=0.87 h, 1.4 h, 2.5 h, 0.87h, 6.9 h and 4.5 h for female SCID mice (3 mg/kg, iv), mice (10 mg/kg, po), mice (100 mg/kg, po), female nude rats (3 mg/kg, iv), rat (10 mg/kg, po), male beagle dogs (10 mg/kg, po))[1].

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    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.08 mg/mL (5.87 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (5.87 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Cell Assay
[2]

Cell proliferation is measured by quantifying intracellular ATP using CellTiter-Glo kit. Cells seeded into 96-well black microplates in complete medium, are treated with single or combined agents (e.g., SAR260301) 0.3 nM-30 μM (0.1% DMSO final concentration) for 96 hours[2].

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

Animal Administration
[1]

Mice[1]
SAR-260301 is evaluated for its antitumor effects in UACC-62 melanoma subcutaneous xenografts in SCID mice. Tumors are allowed to reach at least 150 mm3 before treatment, and tumor volume is measured regularly over the treatment period. Mice are treated orally with SAR-260301 at the dose of 150 mg/kg using a bidaily (BID) schedule in order to favor sustained pathway inhibition and allow comparison with the study performed in PC3 model[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.
