Bioactivity | ML281 is a potent and selective STK33 inhibitor with IC50 of 14 nM. ML281 showed a 550-fold selectivity over AurB and greater than 700-fold selectivity over PKA.target: STK33IC50: 14 nM [1]ML281 showed low nanomolar inhibition of purified recombinant STK33 and a distinct selectivity profile as compared to other STK33 inhibitors. Even at the highest concentration tested (10 μM), ML281 had no effect on the viability of KRAS-dependent cancer cells. [2] | ||||||||||||
