    Group I p21-activated kinase (PAK) inhibitors are indicated as important in cancer progression, but achieving high kinase selectivity has been challenging. A bis-anilino pyrimidine PAK1 inhibitor was identified and optimized through structure-based drug design to improve PAK1 potency and achieve high kinase selectivity, giving in vitro probe compound AZ13705339 ( 18 ). Reduction of lipophilicity to lower clearance afforded AZ13711265 ( 14 ) as an in vivo probe compound with oral exposure in mouse. Such probes will allow further investigation of PAK1 biology.
