Background | Losmapimod is a dual inhibitor of IGF-1 and insulin receptors. |
Biological Activity | Losmapimod是 IGF-1 和胰岛素受体的双重抑制剂,IC50 分别为35 和 75 nM。[1-5] |
In Vitro | Linsitinib抑制IGF-1R自身磷酸化和下游信号蛋白Akt,ERK1/2和S6激酶的激活,IC50为0.028至0.13μM。 Linsitinib通过与C-螺旋的相互作用实现靶蛋白的中间构象。 Linsitinib在肝微粒体中显示出有利的代谢稳定性。 Linsitinib在1μM浓度下完全抑制IR和IGF-1R磷酸化。 Linsitinib抑制几种肿瘤细胞系的增殖,包括非小细胞肺癌和结直肠癌(CRC)肿瘤细胞系,EC50为0.021-0.810μM[1]。 |
In Vivo | Linsitinib在IGF-1R驱动的异种移植小鼠模型中抑制肿瘤生长,在75mg/kg和60%TGI的剂量下具有100%TGI和55%消退,并且在25mg/kg的剂量下无消退。 Linsitinib给药在狗,大鼠和小鼠中诱导其自身的不同消除半衰期,消除半衰期分别为1.18小时,2.64小时和2.14小时。在雌性Sprague-Dawley大鼠和女性CD-1小鼠中每日一次的不同单剂量的Linsitinib给药显示Vmax与Linsitinib剂量不是剂量成比例的。在给药12天后,Linsitinib以25mg/kg的剂量升高血糖水平。 LIZitinib在IGF-1R驱动的全长人IGF-1R(LISN)异种移植小鼠模型中以75mg/kg的单剂量给药,在4至24小时内用血浆药物实现IGF-1R磷酸化(80%)的最大抑制浓度为26.6-4.77μM[1]。在NCI-H292异种移植物小鼠中以60mg/kg的单剂量施用的Linsitinib在体内治疗后2,4和24小时抑制葡萄糖的摄取。 Linsitinib抑制NCI-H292异种移植小鼠模型中肿瘤的生长[2]。 |
Cell Experiment | 对于细胞增殖的测定,将细胞接种到含有10%FCS的适当培养基中的96孔板中,并在Linsitinib存在下以各种浓度培养3天。使用CellTiterGlo通过细胞内ATP含量的发光定量来确定细胞生长的抑制。数据表示为最大增殖的一部分,通过将存在不同浓度的Linsitinib时的细胞密度除以仅用载体(DMSO)处理的对照细胞的细胞密度来计算。 |
Animal Experiment | 在指数细胞生长期间从细胞培养瓶中收获细胞,用无菌PBS洗涤两次至合适的浓度,然后皮下植入雌性nu/nu CD-1小鼠的右胁腹。将肿瘤建立至200±50mm 3大小,然后随机分成8只小鼠的治疗组,每组用于功效研究。如所示口服施用Linsitinib或媒介物。所示的%TGI值是整个给药期间的中值%TGI。 505的TGI被认为是重要的。生长延迟计算为TC,T和C是治疗(T)组和对照(C)组中平均肿瘤大小达到初始肿瘤体积的400%的天数。治疗不包括在此计算中。 |
Kinase Experiment | 蛋白激酶测定或者通过基于ELISA的测定方法(IGF-1R,IR,EGFR和KDR)在内部进行,或者通过使用100μM浓度的ATP的放射测定方法进行。内部ELISA测定使用聚(Glu:Tyr)作为与96孔测定板表面结合的底物,并使用与辣根过氧化物酶偶联的抗磷酸酪氨酸抗体检测磷酸化。通过测量405/490nm处的吸光度,使用ABTS作为过氧化物酶底物定量结合的抗体。所有测定使用纯化的重组激酶催化结构域人IGF-1R或EGFR的重组酶在昆虫细胞中表达为NH2-末端谷胱甘肽S-转移酶融合蛋白,并在室内纯化。 IC50值由抑制百分比对log10化合物浓度的S形剂量 - 反应曲线确定。除非另有说明,否则使用内部测定进行至少三次一式两份的测量。使用ProfilerProTM激酶选择性测定试剂盒,对一组激酶分析浓度为1μM的Linsitinib。 |
