Description

NSC-70220 is a selective and allosteric SOS1 inhibitor. NSC-70220 inhibits allosteric site activation, and partially inhibited catalytic site activation. NSC-70220 has an anticancer effect[1].

IC50 & Target

SOS1[1].
In Vitro

The growth inhibitory rate (IR)=(average OD value in the control group-average OD value in the treatment group)/average OD value in the control group×100% are compared. Treatments with NSC-70220 at 40 μM and NSC-658497 at 30 μM result in growth inhibitory rate of 29% and 8% respectively. The combination treatment results in growth inhibitory rate of 54%, showing the synergistic effect of NSC-70220 and NSC-658497 on cell growth inhibition. It is showed that the treatment with NSC-658497 at 40 μM for 2 hours alone or in combìnation with the treatment with 40 μM of NSC-70220 overnight resulted in lower expression levels of P-AKT and P-ERK. The treatment wlth 40 μM of NSC-70220 overnight resulted in lower expression levels of P-ERK[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: ≥ 1.25 mg/mL (3.84 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.25 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (12.5 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% Corn Oil

    Solubility: ≥ 1.25 mg/mL (3.84 mM); Clear solution

    This protocol yields a clear solution of ≥ 1.25 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 (12.5 mg/mL) to 900 μL Corn oil, and mix evenly.

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.
