SHY-855

Avis client

Based on 1 Customer Validation

SHY-855 is a pan RAS inhibitor. SHY-855 effectively prevents the binding of K-Ras proteins and other members of the Ras superfamily of small GTPases with IC₅₀ values of 0.3-5 μM. SHY-855 effectively inhibits the phosphorylation of MEK, ERK1/2, and AKT downstream of K-Ras. SHY-855 inhibits the formation of the Ras-GTP activity complex. SHY-855 can be used to the studies of pancreatic cancer and non-small cell lung cancer.

In Vitro

SHY-855 competes with GTP binding to K-Ras WT, the G12D, G12C, and Q61H mutants, as well as Rac-1, Rho-A, Rab5, and Rab35 with IC₅₀s of 2.5, 2.5, 3, 5, 2.5, 2.5, 0.3 and 0.6 μM^[1].
SHY-855 (72 h) exhibits potent antiproliferative effects in multiple tumor cell lines, including pancreatic cancer (PANC-1, MIA PaCa-2, BxPC3) and non-small cell lung cancer (NCI-H1975, A549, NCI-H1299), with IC₅₀ values ranging from 0.75-2.9 μM^[1].
SHY-855 (0.3-10 μM, 6 h) significantly inhibits the phosphorylation of key signaling molecules induced by EGF in PANC-1, MIA PaCa-2 and NCI-H1975 cells^[1].
SHY-855 (1.25-10 μM, 6 h) inhibits Ras-GTP complex formation with an IC₅₀ of 1-3 μM in PANC-1, MIA PaCa-2 and NCI-H1975 cells^[1].

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

In Vivo:

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

Stock Solution Working Solution

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: ≥ 3.33 mg/mL (6.58 mM); Clear solution

This protocol yields a clear solution of ≥ 3.33 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 (33.3 mg/mL) to 900 μL Corn oil, and mix evenly.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
