In vivo batch selection In vivo Batch:
Homogeneous suspension	CMC-NA	≥5mg/ml	Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.	1.400mg/ml (3.33mM)	Taking the 1 mL working solution as an example, add 50 μL of clarified DMSO stock solution of 28 mg/ml to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify it; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.

Mechanism of Action

Targets/IC₅₀/Ki	KLF5 (Cell-free assay) 4.4 nM
In vitro	Treatment with SR18662 significantly reduces growth and proliferation of CRC cells. This compound shows improved efficacy in reducing viability of multiple CRC cell lines. Flow cytometry analysis following its treatment shows an increase in cells captured in either S or G2/M phases of the cell cycle and a significant increase in the number of apoptotic cells. This chemical treatment also reduces the expression of cyclins and components of MAPK and WNT signaling pathways.
In vivo	A significant dose-dependent inhibition of xenograft growth in mice is observed following SR18662 treatment that exceeds the effect of ML264 at equivalent doses. This compound is potential for colorectal cancer therapy.
