ML281(CAT: I001552) is a potent and selective inhibitor of the serine/threonine kinase 33 (STK33). STK33 is involved in various cellular processes, including cell proliferation, cell cycle regulation, and tumorigenesis. By inhibiting the activity of STK33, ML281 has the potential to modulate these cellular processes and may have therapeutic implications in diseases where STK33 dysregulation is implicated, such as cancer. Its selectivity towards STK33 makes it a valuable tool compound for studying the function of this kinase and its potential as a therapeutic target.
