HS-438 is a potent and selective BCR-ABL inhibitor. HS-438 shows antiproliferative activity. HS-438 decreases the expression of phosphorylation of BCR-ABL (Tyr177). HS-438 induces apoptosis and cell cycle arrest at G0/G1 phase. HS-438 shows antitumor activity. HS-438 has the potential for the research of chronic myeloid leukemia (CML).
