CAS:Ethyl 3,6-dioxocyclohexa-1,4-diene-1-sulfonate is an analog that has shown potential as an anticancer agent. It works by inhibiting kinases that are involved in cancer cell growth and proliferation. Studies have shown that this compound induces apoptosis in human tumor cells, making it a promising candidate for cancer treatment. Ethyl 3,6-dioxocyclohexa-1,4-diene-1-sulfonate has also been found to be a potent inhibitor of protein kinase D (PKD), which plays a key role in cancer cell survival and proliferation. This compound has been compared to the well-known kinase inhibitor saxagliptin and found to be more effective at inhibiting PKD activity. Additionally, Chinese hamster ovary cells treated with Ethyl 3,6-dioxocyclohexa-1,4-diene-1-sulfonate showed reduced levels of urinary exFormula:C12H12CaO11S2Purity:Min. 95%Molecular weight:436.4 g/mol
