KRAS inhibitor-9
Based on 1 Customer Validation
KRAS inhibitor-9, a potent KRAS inhibitor (Kd=92 μM), blocks the formation of GTP-KRAS and downstream activation of KRAS. KRAS inhibitor-9 binds to KRAS G12D, KRAS G12C and KRAS Q61H protein with a moderate binding affinity. KRAS inhibitor-9 causes G2/M cell cycle arrest and induces apoptosis. KRAS inhibitor-9 selectively inhibits the proliferation of NSCLC cells with KRAS mutation but not normal lung cells.

Biological Activity
KRAS inhibitor-9 bound to KRASG12D, KRAS G12C and KRAS Q61H protein with a moderate binding affinity of -5.38, -5.41, and -3.97 kcal/mol, respectively[1].
KRAS inhibitor-9 (0-100 μM) shows strong inhibition selectivity in NSCLC cells with IC50s ranging from 39.56 to 66.02 μM for H2122, H358 and H460 cells (at 72 hours)[1].
KRAS inhibitor-9 (0-100 μM; 24 hours) blocks GTP-KRAS formation in H2122, H358 and H460 cells[1].
KRAS inhibitor-9 (25-100 μM; 48 hours) inhibits the activation of KRAS downstream signaling pathway[1].
KRAS inhibitor-9 (0-100 μM; 24-72 hours) induces cell cycle arrest and apoptosis in NSCLC[1].

Solvent & Solubility
DMSO : 250 mg/mL (853.80 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

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.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.08 mg/mL (7.10 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.
