The invention relates to compounds of formula (I) which are inhibitors of MKK4 (mitogen-activated protein kinase kinase 4) and their use in promoting liver regeneration or reducing or preventing hepatocyte death. The compounds selectively inhibit protein kinase MKK4 over protein kinases JNK and MKK7. (I), wherein R x, R y , R z and R zz are selected from: a) R x and R y are F and R z and R zz are H; b) R x, R y and R zz are independently halogen and R z is H; c) R x R z and R zz are independently halogen and R y is H; and d) R x R y and R z are independently halogen and R zz is H
该发明涉及式(I)的化合物,这些化合物是MKK4 (丝裂原活化蛋白激酶激酶4)的
抑制剂,用于促进肝再生或减少或预防肝
细胞死亡。这些化合物选择性地抑制蛋白激酶MKK4,而不影响蛋白激酶JNK和MKK7。(I)中,其中 Rx、Ry、Rz和Rzz从以下选项中选择:a) Rx和Ry为F,Rz和Rzz为H;b) Rx、Ry和Rzz独立为卤素,Rz为H;c) Rx、Rz和Rzz独立为卤素,Ry为H;以及d) Rx、Ry和Rz独立为卤素,Rzz为H。
