Clear solution	5% DMSO 1 95% corn oil	0.35mg/ml	Taking the 1 mL working solution as an example, add 50 μL of 7 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results.
Clear solution	5%DMSO 1 40%PEG300 2 5%Tween80 3 50%ddH2O	1.4mg/ml	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.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description

SR18662 is an optimized compund based on ML264 that inhibits Krüppel-like factor 5 (KLF5) with IC50 of 4.4 nM. SR18662 reduces the viability of multiple colorectal cancer cell lines. SR18662 induces apoptosis.

Targets

KLF5 ^[1]
(Cell-free assay)

4.4 nM

In vitro

Treatment with SR18662 significantly reduces growth and proliferation of CRC cells. SR18662 shows improved efficacy in reducing viability of multiple CRC cell lines. Flow cytometry analysis following SR18662 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. SR18662 treatment also reduces the expression of cyclins and components of MAPK and WNT signaling pathways.^[1]

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. SR18662 is potential for colorectal cancer therapy.^[1]
