PLX8394

产品编号 T3579   CAS 1393466-87-9

PLX8394 是一种口服活性的丝氨酸/苏氨酸蛋白激酶 B-Raf (BRAF) 蛋白抑制剂。 PLX8394 可以选择性地结合并抑制野生型和突变形式的 BRAF 的活性,然后抑制表达 BRAF 突变形式的肿瘤细胞的增殖。 PLX8394 似乎对表达多种激酶突变形式的肿瘤有效,并且可能是对其他对 BRAF V600E 突变体特异的 BRAF 抑制剂疗法耐药的肿瘤的有效治疗剂。

产品描述 PLX8394 is an orally active inhibitor of serine/threonine-protein kinase B-Raf (BRAF) protein. PLX8394 can selectively bind to and inhibit the activity of both wild-type and mutated forms of BRAF, then inhibit the proliferation of tumor cells which express mutated forms of BRAF. PLX8394 appears to be effective against tumors that express multiple mutated forms of the kinase and may be an effective therapeutic agent for tumors that are resistant to other BRAF inhibitor therapies that are specific for the BRAF V600E mutant.
靶点活性 BRAF:14 nM, Raf:23 nM, B-Raf (V600E):3.8 nM
体外活性 PLX8394 (>25 nM) effectively inhibits phosphorylation of ERK1/2 in PRT 3 and PRT 4 cells and in addition to parental cells at 10 nM. PLX8394 effectively reduces phosphorylation of retinoblastoma protein, cyclin D3/D1, and expression of cyclin A2 in parental cells and PRT 3/4 cells. PLX8394 inhibits ERK1/2 phosphorylation and the growth of vemurafenib-resistant cells harboring either a BRAF V600K/L505H double mutation or a transposon-induced, N-terminal truncated form of BRAF[1]. PLX8394 significantly impairs tumor cell growth and suppresses MAPK signaling in LA cell lines expressing either endogenous V600E or non-V600 mutant forms of BRAF[2].
体内活性 In mice H1755 xenograft tumors, PLX8394 (150 mg/kg/day) substantially suppresses tumor growth, tumor cell proliferation and MAPK pathway signaling without overt toxicity. PLX8394 combines with erlotinib yields plasma erlotinib concentrations of >1 μM[2].
细胞实验 Dissolvent: DMSO. For MTT assays, 2×103?cells are seeded in triplicate in 96 wells in their regular culture medium (containing PLX4720 for PRT lines). Next day, cells are washed twice with PBS and then the medium is replenished containing the indicated RAF inhibitor. Medium is changed 48 hours later and after a further 48 hours, 10 μL of 5 mg/mL MTT reagent is added to wells and incubated for three hours. Formazan crystals are then solubilized overnight with a 1:10 dilution of 0.1 M glycine (pH 10.5) in DMSO. Wells are then analyzed at 450 nM in a Multiskan Spectrum spectrophotometer. Results depicted are normalized to DMSO conditions and are a composite of three independent experiments. Error bars shown are representative of the standard error of mean (SEM).
动物实验 PLX8394 is dissolved in PEG 400 [20% (v/v)], TPGS [5% (v/v)], and water [75% (v/v)].H1755 tumor xenografts are generated by injection of 5×106 cells in a 50/50 mixture for matrigel and PBS into 6- to 8-wk-old female NOD/SCID mice. Mice are randomized to treatment groups once tumors reach an average size of 150 mm3. H1755 cells are s.c. implanted and allowed to grow to appr 200 mm3 (4 wk after implantation). Mice are then treated with vehicle, vemurafenib, or PLX8394 for 15 d. The vehicle for daily oral gavage is PEG 400 [20% (vol/vol)], tocopheryl polyethylene glycol succinate (TPGS) [5% (vol/vol)], water [75% (vol/vol)]. PLX8394 is dissolved in PEG 400 [20% (vol/vol)], TPGS [5% (vol/vol)], and water [75% (vol/vol)] and vortexed continuously throughout the dosing period. PLX8394 (p.o.) is given at a dose of 150 mg/kg/d.

TargetMol Calculator 体内实验配液计算器

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。
