体外研究

ARRY-470(LOXO-101)是一种选择性的激酶抑制剂，对TRKA、TRKB和TRKC具有摩尔级别的活性，而对其他激酶的抑制活性都大于1000 nM。ARRY-470并不对表达其他致癌基因（上皮生长因子受体EGFR、ALK或ROS1）的Ba/F3细胞具有增殖抑制的作用、对来自于肺和结肠的不具有NTRK1融合的细胞系也没有此作用。ARRY-470(LOXO-101)能诱导KM12细胞的凋亡并将细胞周期阻滞在G1期^[2]。

体内研究

早期持续的ARRY-470(LOXO-101) 的给药在荷瘤骨中能够显著地减弱骨癌疼痛、抑制感觉神经纤维的异位发芽以及类似神经瘤的结构的形成。但对肿瘤生长和骨骼重建没有显著效果。ARRY-470(LOXO-101)跨越血脑屏障的能力非常有限^[1]。

DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，注：如该浓度超过该批次药物DMSO溶解度，请先联系Selleck）；

体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL ddH₂O，混匀澄清。

注意：1. 首先保证母液是澄清的；
2. 一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
