Antagonizing STAT3 activation with benzo[b]thiophene 1, 1-dioxide based small molecules

STAT3 is an attractive therapeutic target for cancer therapy. However, due to low potency or poor druggability, none of its inhibitors are clinically available. Herein, a series of aminobenzo[b]thiophene 1, 1-dioxides with good drug-likeness properties were designed, synthesized and evaluated as STAT3 inhibitors. Most of them exhibited higher antitumor activity than the small-molecule STAT3 inhibitor, Stattic. Compound 15 was the most potent and had an IC50range in 0.33?0.75?muM in various cancer cell lines. The overexpressed and IL-6 induced phosphorylation levels of STAT3 were both inhibited by 15 without influencing the phosphorylation levels of the upstream kinases Src and Jak2. 15 also suppressed the expressions of STAT3 downstream gene, Bcl-2. 15 effectively increased the ROS levels of cancer cells, induced cancer cell apoptosis and abolished the colony formation ability of cancer cells without affecting bypass kinase p-Erk. Furthermore, 15 in?vivo induced significant antitumor responses, and exhibited less toxicity than Doxorubicin. Together, this study described a class of new STAT3 inhibitors as antitumor agents.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 360576-01-8 is helpful to your research. 360576-01-8

Ester 9 (6.8 g, 25.0 mmol) was dissolved in THF (anhydrous, 50 mL) and cooled to 0 oC. Lithium dimethylammonium borohydride3 (50 mL, 50.0 mmol, 1.0 M THF/hexane) was added drop-wise. After 5 min of stirring, the reaction was complete as judged by TLC and was quenched with HCl (3.0 M) under vigorous stirring until the evolution of gas ceased. The organic layer was separated, and the aqueous layer extracted with EtOAc (3x). The combined organic layers were washed with water and brine followed by drying (Na2SO4). Evaporation of solvent gave a yellow solid, which was recrystallized from isopropanol/water to give the desired primary alcohol as white crystals. (5.7 g, 94% yield), mp 111-113 oC.
