C188-9 (TTI-101) is a STAT3 inhibitor with a K_d value of 4.7 nM. C188-9 targets the SH2 domain of STAT3, blocks the processes of STAT3 ligand binding, receptor recruitment, homodimerization and phosphorylation, and regulates STAT3-mediated genes associated with tumorigenesis and radioresistance. C188-9 regulates STAT1-mediated genes related to radioresistance and reduces the activation level of STAT1. C188-9 downregulates the expression of DNMT1, enhances DAC-induced demethylation and re-expression of RASSF1A, and simultaneously potentiates the anti-tumor effect of DAC on pancreatic cancer cells. C188-9 inhibits both anchorage-dependent and anchorage-independent growth of cancer cells, induces Apoptosis, blocks the growth of tumor xenografts, and suppresses muscle atrophy. C188-9 maintains muscle mass, increases body weight and improves grip strength in tumor-bearing mice. C188-9 can be used in research related to head and neck squamous cell carcinoma, pancreatic cancer, sepsis-related skeletal muscle wasting, non-small cell lung cancer, acute myeloid leukemia and cancer cachexia.

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 40% PEG300 5% Tween-80 45% Saline

Solubility: ≥ 2.08 mg/mL (4.41 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 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.

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.
