當9號染色體上的ABL基因與22號染色體上的BCR基因結合時，形成BCR-ABL融合基因。BCR-ABL被翻譯成具有致癌性的組成型活性酪氨酸激酶。根據(jù)融合位置的不同，形成了分子量范圍為185-210 kDa的多種蛋白質(zhì)變體。BCR-ABL激活JAK/STAT通路和MAPK信號。[3]這種基因在大多數(shù)慢性髓性白血病(CML)患者中發(fā)現(xiàn)，在一些急性淋巴細胞白血病(ALL)或急性髓性白血病(AML)患者中發(fā)現(xiàn)。 Ponatinib是第二代BCR-Abl激酶的pan抑制劑，對BCR-Abl (T315I)的突變形式也有效。野生型和突變型的[1，2] IC50分別為0.5和11 nM。[4]在體外，Ponatinib還抑制幾種其他臨床相關激酶(RET、FLT3、KIT、PDGFRα、PDGFRβ和FGFR1)，在Ba/F3細胞系中的IC50s為5、25、100、5、9和23。[4]
