ALK inhibitor 2 (compound 18) is a potent pyrimidin ALK inhibitor. ALK inhibitor 2 is a potent inhibitor of testis-specific serine/threonine kinase 2 (TSSK2; IC50=37 nM) and focal adhesion kinase (FAK; IC50=5 nM)[1].
Testis-specific serine/threonine kinase 2 (TSSK2) is an important target for reversible male contraception. ALK inhibitor 2 (compound 18) contains a methylpiperazine A ring (R1=Me, X=N) and a D ring with R5=methylsulfonamide. ALK inhibitor 2 can undergo metabolic oxidation to form reactive adducts in the presence of glutathione[1].
