产品描述 | FTI-277 hydrochloride (FTI 277 HCl) is an effective and specific farnesyltransferase (FTase) inhibitor (IC50: 500 pM); this selectivity is about 100-fold than the closely related GGTase I. |
靶点活性 | FTase:500 pM |
体外活性 | 在感染乙型肝炎病毒和丁型肝炎病毒的小鼠体内,FTI-277(50 mg/kg/day,i.p.)可有效清除丁型肝炎病毒血症. |
体内活性 | 在耐药骨髓瘤细胞中,FTI-277对细胞生长有抑制作用,还诱导细胞凋亡。在SH-SY5细胞中,FTI-277对细胞退化、活化、c-Jun-N端激酶级联和Ras激活过程中甲基苯丙胺诱导的毒性有减弱作用。FTI-277抑制Ras加工(IC50:100 nM),但对全细胞中四异戊二烯化Rap1A加工无影响。FTI-277导致辐射后细胞凋亡增加,并使H-ras转化的大鼠胚胎细胞的辐射敏感性增加。 |
激酶实验 | FTase and GGTase I Activity Assay: FTase and GGTase I activities from 60,000×g supernatants of human Burkitt lymphoma (Daudi) cells are assayed. Inhibition studies are performed by determining the ability of Ras CAAX peptidomimetics to inhibit the transfer of [3H]farnesyl and [3H]geranylgeranyl from [3H]farnesylpyrophosphate and [3H]geranylgeranylpyrophosphate to H-Ras-CVLS and H-Ras-CVLL, respectively. |
细胞实验 | Cells are seeded at 8000–14 000 cells/well in 96-well plates. To establish a dose–response to FTI-277, cells are incubated for 96 h in two-fold serial dilutions ranging from 3.75 times 10-7 M to 1 times 10-5 M. Following continuous drug exposure, 50 μL MTT dye is added. The insoluble formazan complex is solubilized with DMSO and absorbance measured at 540 nm. IC50s and 95% confidence intervals are calculated by regression analysis of the linear portion of the dose–response curve. (Only for Reference) |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
