生物活性&实验参考方法
体外研究 (In Vitro)
当用 5、10 和 20 μM 利巴韦林 GMP (ICN-1229) 处理 LPS 刺激的小胶质细胞时,NO2 水平降低了 43% (p<0.05)、53% (p<0.05) 和 59%( p<0.05)。在非刺激培养物中,利巴韦林 GMP (ICN-1229) (10 mM) 不会显着减少细胞表面积;然而,在 LPS 刺激的小胶质细胞中,它确实显着减少了细胞表面积(32%,p<0.05)[3]。将利巴韦林 GMP (ICN-1229) 与 CM-10-18 组合可减少病毒复制,并且利巴韦林 GMP (ICN-1229) 对 DENV 具有活性,在 A549 细胞中的 EC50 为 3 μM [4]。给予利巴韦林 (20 μM) 7 天后,在源自人 iPSC 细胞的功能性肝细胞样细胞中,丙型肝炎病毒 (HCV) 复制受到抑制 [6]。通过控制与细胞凋亡调节相关的基因,利巴韦林(1、10、25 μg/mL,72 小时)可减少 ZILV 诱导的 hNPC 细胞凋亡,并通过 PI3K/AKT 途径增强生存信号传导 [7]。实时 qPCR[7]
体内研究 (In Vivo)
JAT 与干扰素和利巴韦林 GMP (ICN-1229) 联合使用,可显着降低 (p<0.01) ALT、AST 活性和胆红素水平。 JAT、干扰素或利巴韦林 GMP 当与 CCl4 单独给药时,珊瑚似乎对 CCl4 有一定的保肝作用,如无谷物、喂养极差和肝索正常所示。在单独或联合使用 JAT、聚搅拌剂和利巴韦林 GMP (ICN-1229) 治疗组中,TGF-β 和 Bax 表达降低。接受干扰素、利巴韦林 GMP (ICN-1229) 和 JAT 的三联治疗组 p53 表达显着下降 [1]。在血清和脐带水平上,用 400 mg 利巴韦林 GMP (ICN-1229) 胶囊治疗的 Wistar 的激活素 A 显着下降,卵泡抑素大幅增加。利巴韦林 GMP (ICN-1229):在小鼠中,利巴韦林 GMP(40 mg/kg,口服)与 IFN-α 或 Peg-IFN-α 联合使用时仅显着升高 CM-10,其抗病毒效果为 -18。在培养细胞中,利巴韦林 GMP (ICN-1229) 会降低抗病毒活性 [2]。 DENV病毒感染,同时用单一药物治疗可以减轻病毒警报[4]。

药代性质 (ADME/PK)
吸收、分布和排泄
据报道,利巴韦林口服后吸收迅速且广泛。口服1200 mg利巴韦林后,平均2小时达到血药浓度峰值(Cmax)。单次口服600 mg利巴韦林后,其口服生物利用度为64%。
利巴韦林的代谢产物经肾脏排泄。口服600 mg放射性标记的利巴韦林后,约61%的药物在尿液中检测到,12%在粪便中检测到。17%的给药剂量以原形排出。
利巴韦林的分布容积较大。
单次口服1200 mg利巴韦林后,总表观清除率为26 L/h。
利巴韦林经鼻腔和口腔吸入后,可经呼吸道系统性吸收。经鼻和经口吸入给药的利巴韦林的生物利用度尚未确定,但可能取决于雾化给药方式(例如,氧气罩、面罩、氧气帐篷)。在恒定流速下,理论上到达呼吸道的药物量与雾化药物溶液的浓度和吸入治疗的持续时间直接相关。此外,气溶胶给药方式的改变也会影响到达呼吸道的药物量。使用小颗粒气溶胶发生器经口和鼻吸入浓度为 190 μg/L 的利巴韦林雾化溶液时,吸入剂量中沉积在呼吸道的比例估计平均约为 70%,但实际沉积量取决于多种因素,包括呼吸频率和潮气量。
使用小颗粒气溶胶发生器经口和鼻吸入药物时,血浆利巴韦林峰值浓度通常出现在吸入结束时,并随着吸入时间的延长而增加。在少数儿科患者中,连续 3 天,每天经面罩以 0.82 mg/kg/hr 的剂量经鼻和口吸入 2.5 小时后,血浆利巴韦林峰值浓度平均为 0.19 μg/mL(范围:0.11-0.388 μg/mL)。在少数患者中,分别以0.82 mg/kg/小时的剂量每日吸入5小时或8小时,持续3天,其血浆利巴韦林峰值浓度平均为0.275 μg/mL(范围:0.21-0.35 μg/mL)或1.1 μg/mL(范围:0.45-2.18 μg/mL);在少数儿科患者中,通过面罩、雾化帐篷或呼吸器每日吸入0.82 mg/kg/小时的剂量20小时,持续5天,其血浆利巴韦林峰值浓度平均为1.7 μg/mL(范围:0.38-3.58 μg/mL)。对于给定剂量的利巴韦林,通过气管插管使用气雾剂发生器给药的患者似乎能达到最高的血浆浓度。 ……通过鼻腔和口腔吸入常用剂量的利巴韦林,其血浆峰值浓度低于据报道可使呼吸道合胞病毒斑块形成减少 85-98% 的浓度。
患者通过鼻腔和口腔吸入利巴韦林后,呼吸道分泌物中的利巴韦林浓度可能远高于血浆浓度。在少数儿科患者中,他们每天连续 3 天,每天 8 小时,通过鼻腔和口腔吸入利巴韦林,剂量为 0.82 mg/kg/小时,结果显示,呼吸道分泌物(来自气管插管)中的药物峰值浓度范围为 250-1925 μg/mL。在接受鼻腔和口腔吸入利巴韦林治疗的儿科患者中,每日20小时,连续5天,剂量为0.82 mg/kg/小时,治疗期间呼吸道分泌物(来自气管插管)中的利巴韦林浓度范围为313-28,250 ug/mL,治疗结束时峰值浓度平均为3075 ug/mL(范围:313-7050 ug/mL)。通过鼻腔和口腔吸入在呼吸道分泌物中达到的利巴韦林浓度可能远高于体外抑制呼吸道合胞病毒易感株形成噬斑所需的浓度;然而,由于呼吸道合胞病毒存在于呼吸道病毒感染细胞内,生产商指出,细胞内呼吸道药物浓度可能与血浆利巴韦林浓度更密切相关,而非与呼吸道分泌物中测得的浓度更相关。
口服利巴韦林后吸收迅速,多次给药后1-3小时内即可达到血浆药物峰浓度。然而,由于药物会经历首过代谢,口服利巴韦林的绝对生物利用度平均仅为64%。

代谢/代谢物
首先,也是激活所必需的步骤,利巴韦林在细胞内被腺苷激酶磷酸化,生成利巴韦林单磷酸、二磷酸和三磷酸代谢物。利巴韦林激活并发挥作用后,会经历两条代谢途径:可逆磷酸化或通过去核糖基化和酰胺水解降解生成三唑羧酸代谢物。体外研究表明,利巴韦林不是CYP450酶的底物。
利巴韦林主要代谢为去核糖基化的利巴韦林(1,2,4-三唑-3-甲酰胺),可能发生在肝脏;据报道,1,2,4-三唑-3-甲酰胺对多种RNA和DNA病毒的抗病毒活性与利巴韦林相似。该药物还会代谢为1,2,4-三唑-3-羧酸。体外研究表明,利巴韦林主要通过腺苷激酶和其他细胞酶在细胞内磷酸化,代谢为利巴韦林-5'-单磷酸、-二磷酸和-三磷酸。体内磷酸化很可能是该药物发挥抗病毒活性的必要条件。利巴韦林在红细胞内也会发生磷酸化,主要生成利巴韦林-5'-三磷酸;在红细胞内代谢的药物中,约有81%、16%和3%分别以利巴韦林-5'-三磷酸、二磷酸和单磷酸的形式存在。有研究表明,药物在红细胞内长时间分布可能是由于这些细胞中磷酸酶活性较低所致,药物从细胞中转运出去依赖于磷酸酶的去磷酸化作用。利巴韦林有两种代谢途径:(i) 在有核细胞中发生的可逆磷酸化途径;(ii) 涉及去核糖基化和酰胺水解的降解途径,生成三唑羧酸代谢物。利巴韦林及其三唑甲酰胺和三唑羧酸代谢物经肾脏排泄。
生物半衰期
单次口服1200 mg利巴韦林后,其终末半衰期约为120至170小时。
分布:静脉注射:约0.2小时。消除:吸入:9.5小时。静脉和口服(单次剂量):0.5至2小时。在红细胞中:40天。终末半衰期:静脉和口服:单次剂量:27至36小时。单次口服片剂:120至170小时。稳态:约151小时。
平均值:多次口服给药,胶囊:298 小时。
根据有限的数据,据报道,利巴韦林经鼻和口吸入 3 天后,在呼吸道分泌物中的半衰期约为 1.4-2.5 小时。
在少数儿科患者中,经鼻和口吸入后,利巴韦林的血浆半衰期平均约为 9.5 小时(范围:6.5-11 小时)。在少数健康成人中,单次口服给药后,血浆利巴韦林浓度呈多相下降,给药后 10-80 小时的平均半衰期为 24 小时,末端半衰期为 48 小时或更长。
毒性/毒理 (Toxicokinetics/TK)
药物相互作用
利巴韦林对某些病毒(例如流感病毒)的体外和体内抗病毒活性可能被其他抗病毒药物(例如金刚烷胺、利巴韦林)增强。
利巴韦林可能拮抗司他夫定和齐多夫定对HIV的体外抗病毒活性;应避免利巴韦林与这两种药物同时使用。
不建议口服利巴韦林与地达诺辛合用。临床试验中曾报告过致命性肝功能衰竭、周围神经病变、胰腺炎和症状性高乳酸血症/乳酸性酸中毒的病例。
体外试验结果表明,利巴韦林可增强地达诺辛对人类免疫缺陷病毒(HIV;曾用名HTLV-III/LAV)和莫洛尼鼠肉瘤病毒的抗逆转录病毒活性。相反,体外试验结果表明,利巴韦林可拮抗齐多夫定和扎西他滨对HIV的抗病毒活性。利巴韦林似乎通过促进地达诺辛-S'-三磷酸(地达诺辛的代谢活性代谢物,具有抗病毒活性)的生成来增强地达诺辛的抗逆转录病毒作用。利巴韦林拮抗齐多夫定或扎西他滨抗逆转录病毒作用的机制尚未阐明,但有研究表明,利巴韦林可能干扰药物转化为其活性三磷酸代谢物(分别为脱氧胸苷三磷酸和双脱氧胞苷-S'-三磷酸)的磷酸化步骤。

口服和静脉注射利巴韦林用于治疗拉沙热,并作为高危接触者的暴露后预防用药。它对其他病毒性出血热也可能同样有效,包括肾综合征出血热、克里米亚-刚果出血热和裂谷热。/未包含在美国产品标签中/
利巴韦林吸入溶液可用作治疗年轻成人甲型和乙型流感的辅助药物,尤其是在疾病早期(例如,在出现初始症状后24小时内)开始治疗时。 /未包含在美国产品标签中/
利巴韦林吸入溶液用于治疗由呼吸道合胞病毒 (RSV) 引起的严重下呼吸道感染(包括毛细支气管炎和肺炎),适用于住院婴儿和幼儿,尤其是那些有严重或复杂性 RSV 感染风险的人群;此类人群包括早产儿以及患有结构性或生理性心肺疾病、支气管肺发育不良、免疫缺陷或即将发生呼吸衰竭的婴儿。利巴韦林适用于治疗需要机械通气辅助的婴儿的 RSV 感染。/包含在美国产品标签中/
药物警告
FDA 妊娠风险类别:X /妊娠期间禁用。动物或人体研究,以及研究性或上市后报告均已证实,胎儿畸形或风险明显大于对患者的任何潜在获益。/
在决定是否治疗儿科患者时,应考虑疾病进展的证据,例如肝脏炎症和纤维化,以及预后因素、HCV基因型和病毒载量。应权衡治疗获益与临床试验中观察到的儿科患者的安全性结果。
在接受利巴韦林吸入治疗的婴儿(包括呼吸道合胞病毒感染者)或患有慢性阻塞性肺疾病(COPD)或哮喘的成人中,呼吸功能有时会突然恶化。对于患有危及生命的潜在疾病的婴儿,吸入该药物与呼吸功能加重和恶化、呼吸暂停以及对辅助呼吸的依赖有关。在患有慢性阻塞性肺病(COPD)或哮喘的成人中,利巴韦林治疗常伴有肺功能恶化,一些哮喘成人患者出现呼吸困难和胸痛。健康成人吸入利巴韦林后也观察到轻微的肺功能异常。支气管痉挛、肺水肿、通气不足、紫绀、呼吸困难、细菌性肺炎、气胸、呼吸暂停、肺不张和呼吸机依赖也与利巴韦林吸入治疗相关。一些婴儿在接受利巴韦林治疗期间出现支气管痉挛导致的呼吸状况恶化,经治疗医生判断,这些死亡可能与利巴韦林吸入治疗有关。接受利巴韦林吸入治疗的患者还可能出现皮疹、眼睑红斑和结膜炎。这些症状通常在停用利巴韦林后数小时内消退。此外,接受利巴韦林联合干扰素α-2b治疗的患者中,曾观察到听力障碍(例如听力丧失、耳鸣)、眩晕、高甘油三酯血症以及致命性和非致命性胰腺炎。

药效学
利巴韦林通过增加多种RNA病毒基因组的突变频率,发挥对多种DNA和RNA病毒的直接抗病毒活性。它属于核苷类抗代谢药物,可干扰病毒遗传物质的复制。由于其结构与RNA分子的组成单元相似,该药物可抑制RNA依赖性RNA聚合酶的活性。

注意: 以上为较为常见方法,仅供参考, InvivoChem并未独立验证这些配方的准确性。具体溶剂的选择首先应参照文献已报道溶解方法、配方或剂型,对于某些尚未有文献报道溶解方法的化合物,需通过前期实验来确定(建议先取少量样品进行尝试),包括产品的溶解情况、梯度设置、动物的耐受性等。

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。

5 mM 0.8190 mL 4.0950 mL 8.1900 mL
10 mM 0.4095 mL 2.0475 mL 4.0950 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。

计算器

摩尔浓度计算器可计算特定溶液所需的质量、体积/浓度,具体如下:

  • 计算制备已知体积和浓度的溶液所需的化合物的质量
  • 计算将已知质量的化合物溶解到所需浓度所需的溶液体积
  • 计算特定体积中已知质量的化合物产生的溶液的浓度
使用摩尔浓度计算器计算摩尔浓度的示例如下所示:
假如化合物的分子量为350.26 g/mol,在5mL DMSO中制备10mM储备液所需的化合物的质量是多少?
  • 在分子量(MW)框中输入350.26
  • 在“浓度”框中输入10,然后选择正确的单位(mM)
  • 在“体积”框中输入5,然后选择正确的单位(mL)
  • 单击“计算”按钮
  • 答案17.513 mg出现在“质量”框中。以类似的方式,您可以计算体积和浓度。

稀释计算器可计算如何稀释已知浓度的储备液。例如,可以输入C1、C2和V2来计算V1,具体如下:

制备25毫升25μM溶液需要多少体积的10 mM储备溶液?
使用方程式C1V1=C2V2,其中C1=10mM,C2=25μM,V2=25 ml,V1未知:
  • 在C1框中输入10,然后选择正确的单位(mM)
  • 在C2框中输入25,然后选择正确的单位(μM)
  • 在V2框中输入25,然后选择正确的单位(mL)
  • 单击“计算”按钮
  • 答案62.5μL(0.1 ml)出现在V1框中
g/mol

分子量计算器可计算化合物的分子量 (摩尔质量)和元素组成,具体如下:

注:化学分子式大小写敏感:C12H18N3O4  c12h18n3o4
计算化合物摩尔质量(分子量)的说明:
  • 要计算化合物的分子量 (摩尔质量),请输入化学/分子式,然后单击“计算”按钮。
分子质量、分子量、摩尔质量和摩尔量的定义:
  • 分子质量(或分子量)是一种物质的一个分子的质量,用统一的原子质量单位(u)表示。(1u等于碳-12中一个原子质量的1/12)
  • 摩尔质量(摩尔重量)是一摩尔物质的质量,以g/mol表示。

配液计算器可计算将特定质量的产品配成特定浓度所需的溶剂体积 (配液体积)

  • 输入试剂的质量、所需的配液浓度以及正确的单位
  • 单击“计算”按钮
  • 答案显示在体积框中
动物体内实验配方计算器(澄清溶液)
第一步:请输入基本实验信息(考虑到实验过程中的损耗,建议多配一只动物的药量)
第二步:请输入动物体内配方组成(配方适用于不溶/难溶于水的化合物),不同的产品和批次配方组成不同,如对配方有疑问,可先联系我们提供正确的体内实验配方。此外,请注意这只是一个配方计算器,而不是特定产品的确切配方。
