体外研究 (In Vitro) |
Ruxolitinib硫酸盐(INCB018424硫酸盐)以剂量依赖性方式显着、选择性地增强细胞凋亡,有效地、选择性地抑制JAK2V617F介导的信号传导和增殖,并在64 nM时导致Ba/F3细胞中线粒体去极化的细胞加倍。 roxolitinib 的 IC50 为 67 nM,对红细胞集落的形成具有显着的功效。它还抑制正常供体和真性红细胞增多症患者的红系祖细胞增殖,IC50 值分别为 407 nM 和 223 nM[1]。

体内研究 (In Vivo) |
Ruxolitinib(INCB018424硫酸盐;180 mg/kg,口服,每天两次)使 JAK2V617F 驱动的小鼠模型表现出显着延长的生存期,且没有骨髓抑制或免疫抑制作用。到第 22 天,它还显着降低炎症细胞因子水平和脾肿大,并优先消除肿瘤细胞[1]。在骨髓纤维化的双盲试验中,鲁索替尼组中 41.9% 的患者和安慰剂组中 0.7% 的患者达到主要终点。 Ruxolitinib 可使总体症状评分改善 50% 或更多,同时保持脾脏体积的缩小[2]。当给予罗索替尼(15 mg,每天两次)时,到第 48 周时,28% 的骨髓纤维化患者的脾脏体积减少了至少 35%,而接受最佳可用治疗的组中这一比例为 0%。到第 48 周时,使用最佳可用疗法时,平均可触及脾脏长度增加了 4%,但使用 Ruxolitinib 时则下降了 56%。接受鲁索替尼治疗的患者整体生活质量指标有所改善,并且骨髓纤维化相关症状有所减轻[3]。

Background: Ruxolitinib, a selective inhibitor of Janus kinase (JAK) 1 and 2, has clinically significant activity in myelofibrosis.
Methods: In this double-blind trial, we randomly assigned patients with intermediate-2 or high-risk myelofibrosis to twice-daily oral ruxolitinib (155 patients) or placebo (154 patients). The primary end point was the proportion of patients with a reduction in spleen volume of 35% or more at 24 weeks, assessed by means of magnetic resonance imaging. Secondary end points included the durability of response, changes in symptom burden (assessed by the total symptom score), and overall survival. Results: The primary end point was reached in 41.9% of patients in the ruxolitinib group as compared with 0.7% in the placebo group (P<0.001). A reduction in spleen volume was maintained in patients who received ruxolitinib; 67.0% of the patients with a response had the response for 48 weeks or more. There was an improvement of 50% or more in the total symptom score at 24 weeks in 45.9% of patients who received ruxolitinib as compared with 5.3% of patients who received placebo (P<0.001). Thirteen deaths occurred in the ruxolitinib group as compared with 24 deaths in the placebo group (hazard ratio, 0.50; 95% confidence interval, 0.25 to 0.98; P=0.04). The rate of discontinuation of the study drug because of adverse events was 11.0% in the ruxolitinib group and 10.6% in the placebo group. Among patients who received ruxolitinib, anemia and thrombocytopenia were the most common adverse events, but they rarely led to discontinuation of the drug (in one patient for each event). Two patients had transformation to acute myeloid leukemia; both were in the ruxolitinib group. Conclusions: Ruxolitinib, as compared with placebo, provided significant clinical benefits in patients with myelofibrosis by reducing spleen size, ameliorating debilitating myelofibrosis-related symptoms, and improving overall survival. These benefits came at the cost of more frequent anemia and thrombocytopenia in the early part of the treatment period. (Funded by Incyte; COMFORT-I ClinicalTrials.gov number, NCT00952289.). |

溶解度 (体内实验) |
注意: 如下所列的是一些常用的体内动物实验溶解配方,主要用于溶解难溶或不溶于水的产品(水溶度<1 mg/mL)。 建议您先取少量样品进行尝试,如该配方可行,再根据实验需求增加样品量。
注射用配方
注射用配方1: DMSO : Tween 80: Saline = 10 : 5 : 85 (如: 100 μL DMSO → 50 μL Tween 80 → 850 μL Saline)(IP/IV/IM/SC等) *生理盐水/Saline的制备:将0.9g氯化钠/NaCl溶解在100 mL ddH ₂ O中,得到澄清溶液。 注射用配方 2: DMSO : PEG300 :Tween 80 : Saline = 10 : 40 : 5 : 45 (如: 100 μL DMSO → 400 μL PEG300 → 50 μL Tween 80 → 450 μL Saline) 注射用配方 3: DMSO : Corn oil = 10 : 90 (如: 100 μL DMSO → 900 μL Corn oil) 示例: 以注射用配方 3 (DMSO : Corn oil = 10 : 90) 为例说明, 如果要配制 1 mL 2.5 mg/mL的工作液, 您可以取 100 μL 25 mg/mL 澄清的 DMSO 储备液,加到 900 μL Corn oil/玉米油中, 混合均匀。 View More
注射用配方 4: DMSO : 20% SBE-β-CD in Saline = 10 : 90 [如:100 μL DMSO → 900 μL (20% SBE-β-CD in Saline)] 口服配方
口服配方 1: 悬浮于0.5% CMC Na (羧甲基纤维素钠) 口服配方 2: 悬浮于0.5% Carboxymethyl cellulose (羧甲基纤维素) 示例: 以口服配方 1 (悬浮于 0.5% CMC Na)为例说明, 如果要配制 100 mL 2.5 mg/mL 的工作液, 您可以先取0.5g CMC Na并将其溶解于100mL ddH2O中,得到0.5%CMC-Na澄清溶液;然后将250 mg待测化合物加到100 mL前述 0.5%CMC Na溶液中,得到悬浮液。 View More
口服配方 3: 溶解于 PEG400 (聚乙二醇400) 请根据您的实验动物和给药方式选择适当的溶解配方/方案: 1、请先配制澄清的储备液(如:用DMSO配置50 或 100 mg/mL母液(储备液)); 2、取适量母液,按从左到右的顺序依次添加助溶剂,澄清后再加入下一助溶剂。以 下列配方为例说明 (注意此配方只用于说明,并不一定代表此产品 的实际溶解配方): 10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline); 假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀/澄清;向上述体系中加入50 μL Tween-80,混合均匀/澄清;然后继续加入450 μL ddH2O (或 saline)定容至 1 mL; 3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例; 4、 如产品在配制过程中出现沉淀/析出,可通过加热(≤50℃)或超声的方式助溶; 5、为保证最佳实验结果,工作液请现配现用! 6、如不确定怎么将母液配置成体内动物实验的工作液,请查看说明书或联系我们; 7、 以上所有助溶剂都可在 Invivochem.cn网站购买。 |
制备储备液 | 1 mg | 5 mg | 10 mg | |
1 mM | 2.4726 mL | 12.3628 mL | 24.7255 mL | |
5 mM | 0.4945 mL | 2.4726 mL | 4.9451 mL | |
10 mM | 0.2473 mL | 1.2363 mL | 2.4726 mL |
1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
工作液浓度: mg/mL;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL ddH2O,混匀澄清。
(1) 请确保溶液澄清之后,再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶;
(2) 一定要按顺序加入溶剂 (助溶剂) 。
