CAS:Piquindone is a medicinal compound that has shown promising anticancer properties in human tumor cells. It acts as an inhibitor of protein kinases, which are enzymes that regulate cell growth and division. Piquindone is an analog of a natural product found in Chinese urine and has been studied for its ability to induce apoptosis, or programmed cell death, in cancer cells. This compound has shown potent activity against various types of cancer cells and may have potential as a therapeutic agent for the treatment of cancer. Its mechanism of action involves the inhibition of specific kinases involved in cancer cell proliferation and survival. Piquindone is being investigated further for its potential as a cancer cell inhibitor.Formula:C15H22N2OPurity:Min. 95%Molecular weight:246.35 g/molEtoposide
