Description: KW-2449 is a novel multikinase inhibitor, which suppresses the growth of leukemia cells with FLT3 mutations or T315I-mutated BCR/ABL translocation. Recent research showed that HDACIs increase KW-2449 lethality in Bcr/Abl(+) cells in association with inhibition of Bcr/Abl, generation of ROS, and induction of DNA damage. This strategy preferentially targets primary Bcr/Abl(+) hematopoietic cells and exhibits enhanced in vivo activity. Combining KW-2449 with HDACIs warrants attention in IM-resistant Bcr/Abl(+) leukemias. (source: Clin Cancer Res. 2011 May 15;17(10):3219-32. Epub 2011 Apr 7.).

Additional Information

KW-2449, a multikinase inhibitor of FLT3, ABL, ABL-T315I, and Aurora kinase, is under investigation to treat leukemia patients. KW-2449 showed the potent growth inhibitory effects on leukemia cells with FLT3 mutations by inhibition of the FLT3 kinase, resulting in the down-regulation of phosphorylated-FLT3/STAT5, G1 arrest, and apoptosis. Oral administration of KW-2449 showed dose-dependent and significant tumor growth inhibition in FLT3-mutated xenograft model with min. bone marrow suppression. In FLT3 wild-type human leukemia, it induced the redn. of phosphorylated histone H3, G2/M arrest, and apoptosis. In imatinib-resistant leukemia, KW-2449 contributed to release of the resistance by the simultaneous down-regulation of BCR/ABL and Aurora kinases. Furthermore, the antiproliferative activity of KW-2449 was confirmed in primary samples from AML and imatinib-resistant patients. The inhibitory activity of KW-2449 is not affected by the presence of human plasma protein, such as .alpha.1-acid glycoprotein. These results indicate KW-2449 has potent growth inhibitory activity against various types of leukemia by several mechanisms of action. KW-2449 has significant activity and warrants clin. study in leukemia patients with FLT3 mutations as well as imatinib-resistant mutations.  See: Shiotsu, Yukimasa; Kiyoi, Hitoshi; Ishikawa, Yuichi; Tanizaki, Ryohei; Shimizu, Makiko; Umehara, Hiroshi; Ishii, Kenichi; Mori, Yumiko; Ozeki, Kazutaka; Minami, Yosuke; Abe, Akihiro; Maeda, Hiroshi; Akiyama, Tadakazu; Kanda, Yutaka; Sato, Yuko; Akinaga, Shiro; Naoe, Tomoki.
