产品介绍

生物活性

Ispinesib (SB-715992)是一种有效的,特异性的,可逆的kinesin spindle protein (KSP)(纺锤体驱动蛋白)抑制剂,Kiapp为1.7 nM,对CENP-E, RabK6, MCAK, MKLP1, KHC和Kif1A没有抑制作用。Ispinesib 是有效可逆的特定KSP变构抑制剂,KSP与微管的结合性能,通过抑制ADP释放而不改变微管中KSP-ADP复合体的释放,而扰乱KSP的运动。 Ispinesib作用于一系列肿瘤细胞系, 包括Colo205, Colo201, HT-29, M5076, Madison-109,和MX-1, IC50为1.2 nM 到 9.5 nM,具有很强细胞毒性。 15 nM 和 30 nM Ispinesib作用于PC-3前列腺癌细胞, 通过调节控制凋亡,细胞增殖,细胞周期,和信号的基因表达水平,如EGFR, p27, p15, 和IL-11,而抑制细胞增殖和诱导凋亡。

细胞实验
细胞系BT-474 and MDA-MB-468 cells line
方法Cell lines were obtained from the American Type Culture Collection and from collections developed by Drs. Steve Ethier and Adi Gazdar. KPL4 was kindly provided by Dr J. Kurebayashi (Kawasaki Medical School, Kurashiki, Okayama, Japan). Cell culture reagents were from Cellgro-Mediatech. Cells were plated in log phase of growth in 96-well plates and treated for 72 h with ispinesib at concentrations of 3.3 × 10–5to 8.5 × 10–11mol/L. Cell growth was measured using CellTiter-Glo (Promega), and luminescence was recorded using BioTek FLx800. Data were analyzed according to the method described previously by the National Cancer Institute/NIH Developmental Therapeutics Program Human Tumor Cell Line Screen Process. The GI50 value is the drug concentration that results in 50% growth inhibition after 72 h of drug exposure relative to control.

不同实验动物依据体表面积的等效剂量转换表(数据来源于FDA指南)

小鼠大鼠豚鼠仓鼠
重量 (kg)0.020.151.80.40.0810
体表面积 (m2)0.0070.0250.150.050.020.5
Km系数36128520
动物 A (mg/kg) = 动物 B (mg/kg) × 动物 B的Km系数
动物 A的Km系数

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
