Imatinib is a multi-target inhibitor of v-Abl, c-Kit, and PDGFR (IC50: 0.6 μM, 0.1 μM, and 0.1 μM, respectively). Imatinib is used to treat chronicmyelogenousleukemia (CML), gastrointestinal stromal tumors (GISTs), and a number of other malignancies.
BVB-808 is a selective Jak2 type 1 inhibitor. Janus kinases are critical components of signaling pathways that regulate hematopoiesis. Mutations of the non-receptor tyrosine kinase JAK2 are found in many BCR-ABL-negative myeloproliferative neoplasms. Preclinical results support that JAK2 inhibitors could show efficacy in treating chronic myeloproliferative neoplasms. JAK2 has also been postulated to play a role in BCR-ABL signal transduction. Therefore, inhibitors of JAK2 kinases are turning into therapeutic strategies for treatment of chronicmyelogenousleukemia (CML).
