Acetylazide is an analog of a compound found in human urine that has shown promising anticancer activity. It is a potent inhibitor of protein kinases, which are enzymes involved in the regulation of cell growth and division. Acetylazide has been shown to induce apoptosis (cell death) in cancer cells, particularly those associated with thyroid cancer. This compound has also been tested in Chinese hamster ovary cells and has demonstrated a high degree of selectivity for tumor cells over normal cells. Acetylazide may be a promising candidate for the development of new anticancer drugs.
