Background | Asciminib is a potent and selective allosteric inhibitor of ABL1. |
Biological Activity | Asciminib (ABL001)是一种有效的、选择性的ABL1变构抑制剂,Kd值为0.5-0.8 nM,与ABL1的十四酰口袋结合。[1-3] |
In Vitro | ABL001是一种有效的、选择性的BCR-ABL抑制剂,对多数突变型都具有活性,如T315I[1]。ABL001与ABL1的调节位点的结合,在野生型ABL中,这一位点通常是被一个肉豆蔻酰基团所占据。ABL001通过不同于其他靶向催化位点的抑制剂机理抑制了ABL激酶活性[2]。它与BCR-ABL激酶区域的口袋结合,正常状态下,这一区域为ABL1的十八烷基化N端所占,一旦与BCR结合,作用于ABL1自我调节功能的十八烷基化N端丢失。ABL001通过结合这一空白位点,模拟了十八烷基化N端的作用,从而恢复了激酶活性的负向调控功能。浓度为1-10 nM的ABL001可选择性地抑制CML和Ph+ ALL细胞的生长;而即使在浓度高达1000倍以上时,BCR-ABL-阴性细胞不受ABL001的影响[1]。ABL001与ABL的肉豆蔻酰口袋结合的离解常数Kd为0.5-0.8 nM,诱导失活的C端螺旋构象。ABL001对所检测的60多种激酶没有活性,其中包括SRC;同时对G蛋白偶联受体、离子通道、核受体和转运体也没有活性。因此ABL001具有高选择性[3]。 |
In Vivo | 在KCL-22小鼠移植瘤模型中,ABL001具有有效的抗肿瘤活性,能够引起完全的肿瘤消退,并与pSTAT5抑制效果呈浓度依赖性关系[1]。ABL001具有中等的口服吸收度、体内体积分布和半衰期。它作为单药进行给药时,能够诱导临床的抗肿瘤活性,在既往多次化疗的CML(慢性髓细胞性白血病)患者中耐受良好。至于其药代动力学、药效学,在小鼠、大鼠和狗中单次静脉注射1mg/kg,2mg/kg和1mg/kg的ABL001,血浆清除率(CL)分别为12,16和6 mL/min/kg。在小鼠和狗中,单次静脉注射1 mg/kg ABL001,T1/2term分别为1.1和3.7小时。在大鼠中,单次静脉注射2 mg/kg,T1/2term为2.7小时。对小鼠和大鼠口服以30 mg/kg ABL001后,其口服生物利用度分别为35%和27%;而在狗中,口服以15 mg/kg ABL001,口服生物利用度为111%[3]。 |
Cell Experiment | Animal Models: 皮下注射KCL-22细胞的CML移植瘤模型(无胸腺裸鼠,6-8周龄);Dosages: 7.5,15和30 mg/kg;Administration: p.o 或 i.v[3] |
Animal Experiment | 将KCL-22细胞处理以不同浓度范围(0-250 nM)的ABL001,nilotinib或dasatinib,处理1小时。收集细胞,获取蛋白溶解产物,进行WB分析。[3] |
