一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
Pexmetinib(ARRY-614)是细胞因子合成的有效抑制剂,通过对 p38促分裂原活化蛋白激酶和Tie2/Tek受体酪氨酸激酶的双重抑制(MAPK)来发挥作用。ARRY-614体外抑制Tie2和p38促分裂原活化蛋白激酶的IC50值分别是1000 ng/mL和100 ng/mL[1,2]。
p38是一组促分裂原活化蛋白激酶。MAPKs通过在亚结构域VIII的Thr-Xaa-Tyr基序中酪氨酸和苏氨酸位点的双重磷酸化而激活。数据表明,p38蛋白可能介导细胞核信号[3]。
ARRY-614针对细胞中MAPK和Tie2/Tek受体酪氨酸激酶发挥功能。在原代人骨髓基质细胞中,ARRY-614抑制基础的细胞因子,IC50值范围为50-100 nM [4]。
在剂量递增或扩张实验中,45个病人每日一次或两次接受ARRY-614治疗。ARRY-614减少骨髓中循环生物标志物的水平和p38蛋白的活化[1]。在离体刺激的人全血中,ARRY-614抑制LPS诱导的细胞因子,IC50值范围为50-120 nM。ARRY-614抑制接种SEA或LPS的小鼠释放IL-6,ED50值小于10 mg/kg。 ARRY-614与lenalidomide共同作用时,会抑制体内的促炎细胞因子和肿瘤生长,与单独的任一药剂相比,具有更高的效力[4]。
