ML-281 is a potent ans selective STK33 inhibitor with IC50 value of 14 nM. ML281 showed low nanomolar inhibition of purified recombinant STK33 and a distinct selectivity profile as compared to other STK33 inhibitors. STK33 was selectively toxic to KRAS-dependent cancer cell lines, suggesting that small-molecule inhibitors of STK33 might selectively target KRAS-dependent cancers. ML281 is a valuable addition to small-molecule probes of STK33.
