CAS:Dimethrimol is a medicinal compound that has shown potential as an anticancer agent. It is an analog of inhibitors found in Chinese urine that have been used for their apoptotic effects on cancer cells. Dimethrimol has been shown to inhibit kinases, which are enzymes involved in cell signaling and proliferation. This inhibition leads to apoptosis, or programmed cell death, in human cancer cells. Dimethrimol is a promising inhibitor of tumor kinase activity and may be useful in the development of new anticancer therapies. Its protein kinase inhibitory activity makes it a valuable tool for studying the molecular mechanisms underlying cancer cell growth and survival.
