产品描述
催产素是一种神经垂体激素。它是一种发挥重要生理作用的九肽多效性激素。众所周知,它能刺激分娩和哺乳,但对代谢和心血管功能、性行为和母性行为、伴侣关系、社会认知和恐惧条件也有重要的生理影响。值得注意的是,催产素受体不仅限于生殖系统,而且可以在许多外周组织和中枢神经系统结构中发现,包括脑干和杏仁核。

体外研究 (In Vitro)
催产素是一种多效肽激素,对一般健康、适应、发育、繁殖和社会行为有广泛的影响。内源性催产素和催产素受体的刺激支持生长、恢复和愈合模式。催产素可以作为一种压力应对分子、抗炎药和抗氧化剂发挥作用,尤其是在面对逆境或创伤时具有保护作用。催产素影响自主神经系统和免疫系统。催产素的这些特性可能有助于解释积极社会体验的好处,并引起人们对这种分子的关注,认为它可能是一种治疗多种疾病的药物。然而,如本文所述,催产素的独特化学性质,包括活性二硫键,以及其改变化学形式和与其他分子结合的能力,使该分子难以使用和测量。催产素的作用也依赖于环境,性二态性,并因经验而改变。在一定程度上,这是因为催产素的许多作用依赖于它与更古老的肽分子血管加压素和血管加压素受体相互作用的能力。此外,催产素受体通过经验进行表观遗传学调节,尤其是在生命早期。G蛋白偶联受体的刺激触发亚细胞级联反应,使这些神经肽具有多种功能。催产素的适应性使这种古老的分子对人类进化以及现代医学和健康具有特殊的重要性;这些相同的特征也对使用催产素样分子作为药物提出了挑战,而这些药物现在才被认识到。意义声明:催产素是一种古老的分子,在哺乳动物的行为和健康中起着重要作用。尽管催产素有能力作为一种“天然药物”来抵御压力和疾病,但催产素分子及其受体的独特特性及其与相关激素血管加压素的关系,给其作为治疗药物的使用带来了挑战[2]。
体内研究 (In Vivo)
垂体神经肽催产素促进社会行为,是精神分裂症和自闭症社会缺陷的潜在辅助疗法。催产素可以通过调节边缘和皮层区域的单胺释放来介导亲社会效应,本文使用体内微透析对其进行了研究,在确定了一个不会产生可能同时影响行为的镇静或体温调节作用的剂量后。使用选择性拮抗剂测定催产素和加压素V1a受体的作用,研究了催产素(0.03-0.3 mg/kg皮下注射)对成年雄性利斯特帽大鼠运动活动、核心体温和社交行为(社交互动和超声波发声)的影响。使用微透析法评估清醒大鼠前额叶皮层和伏隔核中多巴胺和血清素的流出。0.3mg/kg催产素适度降低活性并引起体温过低,但只有后者被V1a受体拮抗剂SR49059(腹膜内1mg/kg)减弱。0.1 mg/kg的催产素不会改变活动,对温度也几乎没有影响,它显著减弱了苯环利定诱导的多动,并增加了陌生大鼠之间的社交互动,而不会改变超声波发声的数量或模式。在同一只大鼠中,催产素(0.1 mg/kg)选择性地提高伏隔核的多巴胺溢出,但不影响前额叶皮层,而不会影响血清素的流出。全身催产素给药减轻了苯环利定诱导的多动,增加了亲社会行为,但没有降低核心体温,并选择性地增强了伏隔核多巴胺的释放,这与调节关联/奖励行为的中皮质边缘回路的激活一致。这突出了催产素在治疗精神分裂症等精神疾病中的社会行为缺陷方面的治疗潜力[1]。
- 在大鼠模型中,给予催产素(Oxytocin)可减轻苯环利定(PCP)诱导的过度活动,增加社交互动行为,并促进伏隔核内多巴胺的释放 [1]
酶活实验
单胺分析[1]
如前所述,使用具有电化学检测的高效液相色谱法分析微透析样品。注射前将解冻的样本保存在冰上(15 µl)注入Targa C18 3 µM柱(100 × 1 m) 使用Perkin Elmer Series 200自动进样器。多巴胺、5-羟色胺及其主要代谢产物;使用流动相(20 mM磷酸二氢钾,20 mM乙酸钠,0.1 mM乙二胺四乙酸,0.15 mM辛烷磺酸和10%甲醇,pH 3.9)在0.4 ml/min(Dionex P680泵),并使用DECADE II SDC Detector I和Clarity软件对照标准进行测量+ 0.75 V.计算每只大鼠的每种微透析物分子与基线的百分比变化。一只大鼠因探针放置不正确而被排除在PFC样本之外,另外两只大鼠因血流中断而被排除。在一只大鼠中,NAc多巴胺低于检测限;n = PFC中每组6/7,n = 在NAc中为7/8。
动物实验
催产素对核心体温和运动活性的剂量-反应及拮抗剂研究[1]
为了确定合适的催产素剂量,使其在微透析研究中不会抑制运动活性(LMA)或导致体温过低,我们采用受试者内设计,对12只大鼠进行了四次测试。每次测试前,大鼠均先注射赋形剂,然后以伪随机顺序皮下注射不同剂量的催产素(0.03、0.1或0.3 mg/kg),作为自身对照。之所以选择该剂量范围,是因为之前的研究表明,在其他品系的大鼠中,皮下或腹腔注射的催产素剂量高于0.3 mg/kg会抑制自发运动,因此我们纳入了较低剂量,以确定哪些剂量不会产生这种不良反应。为了确定催产素和血管加压素V1a受体对最高剂量引起的体温过低的相对贡献,另外12只大鼠在有或无非肽类选择性V1a受体拮抗剂SR49059(1 mg/kg,腹腔注射)或选择性催产素拮抗剂L-368,899(2 mg/kg,腹腔注射)的情况下,每周接受一次给药,共6次(组内设计)。尽管这些受体的原始肽类拮抗剂稳定性差且选择性低,但非肽类拮抗剂的开发极大地改善了其药代动力学特性。选择目前的非肽类拮抗剂(SR49059和L-368,889)是因为它们在市售的催产素和V1a受体拮抗剂中具有最佳的综合特性。这些拮抗剂具有高亲和力、相对选择性、良好的血脑屏障穿透性和血浆半衰期,且不具有部分激动剂活性。这些可穿透血脑屏障的拮抗剂的剂量是根据既往研究选择的,这些研究显示其在啮齿动物中起效时间小于15分钟,持续时间为2-4小时。SR49059可抑制催产素诱导的亲社会行为和体温过低,而L-368,899(PET研究已证实其可穿透血脑屏障)可抑制催产素在开放场中的抗焦虑作用,减少雄性大鼠在社交互动中的条件性厌恶行为,并减弱其性动机。交叉重复受试者内设计用于剂量反应和拮抗剂研究,大大减少了所需的实验大鼠数量,并降低了测量结果的个体间差异,符合3R原则。
剂量和给药途径:
化合物溶解于0.154 M生理盐水(拮抗剂的溶剂中还含有5%二甲基亚砜),并以1 ml/kg的体积皮下(sc)给药(催产素)。
催产素对PCP诱导的活动过度、社交互动以及前额叶皮层(PFC)和伏隔核(NAc)多巴胺和5-羟色胺(5-HT)外流的影响[1]
选择0.03和0.1 mg/kg的催产素进行进一步研究,因为这些剂量在上述剂量反应研究中未对活动和体温产生混淆效应。另取一组大鼠(n = 32,图 S1)研究这两种剂量对 PCP 诱导的活动过度的影响。基于这些结果,在评估社交互动和超声波发声 (USV) 之前,于 7 天后给予 0.1 mg/kg 催产素。接下来的一周,对大鼠进行立体定位手术,将微透析探针植入前额叶皮层 (PFC) 和伏隔核 (NAc)。术后 7 天恢复期后,评估催产素对这些脑区多巴胺外流的影响。三个实验方案之间间隔一周(图 S1),以确保药物完全清除,并最大限度地减少先前操作的任何残留效应。
运动活性[1]
如上所述,仅评估一次运动活性。动物在适应场地 30 分钟后接受催产素或载体,30 分钟后接受载体或 PCP(5.6 mg/kg 腹腔注射;用于检验“抗精神病样”活性的既定剂量),从而得到四种治疗组合:载体 + 载体、PCP + 载体、PCP + 0.03 mg/kg 催产素、PCP + 0.1 mg/kg(每组 n = 8;组间设计)。
药代性质 (ADME/PK)
吸收、分布和排泄

催产素通过肠外途径给药,具有完全的生物利用度。肠外给药后,催产素在血浆中达到稳态浓度大约需要 40 分钟。

催产素酶主要负责妊娠期间催产素水平的代谢和调节;只有一小部分神经激素以原形经尿液排出。

在一项观察 10 名接受催产素引产的妇女的研究中,平均代谢清除率为 7.87 mL/min。

催产素在胃肠道中被胰凝乳蛋白酶破坏。静脉注射催产素后,子宫反应几乎立即出现,并在 1 小时内消退。肌注催产素后,子宫反应在 3-5 分钟内出现,并持续 2-3 小时。鼻内滴注10-20单位催产素(美国已不再销售鼻用制剂)后,乳腺肺泡周围的肌上皮组织会在几分钟内开始收缩,并持续20分钟;静脉注射100-200毫单位的催产素也能产生相同的效果。
与血管加压素类似,催产素分布于细胞外液中。少量催产素可能进入胎儿循环。
目前尚不清楚该药物是否会分泌到人乳中。
其从血浆中的快速清除主要通过肾脏和肝脏完成。只有少量催产素以原形经尿液排出。

代谢/代谢物
催产素主要通过肝脏和肾脏从血浆中清除。催产素主要负责妊娠期间催产素水平的代谢和调节,只有少量神经激素以原形经尿液排出。催产素酶在整个妊娠期间逐渐增加,并在接近足月时在血浆、胎盘和子宫中达到峰值。催产素酶活性。胎盘是妊娠期间催产素酶的主要来源,并随着母体催产素水平的增加而产生越来越多的酶。乳腺、心脏、肾脏和小肠也表达催产素酶。催产素存在于大脑、脾脏、肝脏、骨骼肌、睾丸和结肠中,活性较低。在非妊娠女性、男性和脐带血中,催产素的降解可以忽略不计。
催产素酶是一种在妊娠早期产生的循环酶,也能使该多肽失活。
在妊娠期间,“催产素酶”能够通过裂解1-半胱氨酸与2-酪氨酸之间的肽键使催产素失活。

生物半衰期
催产素的血浆半衰期为1-6分钟。在妊娠晚期和哺乳期,半衰期会缩短。
催产素的血浆半衰期约为3至5分钟。
毒性/毒理 (Toxicokinetics/TK)
相互作用

据报道,在预防性使用血管收缩剂并联合尾部阻滞麻醉后 3-4 小时给予催产素,可引起严重高血压。

可能改变催产素的心血管效应,与单独使用催产素相比,可引起较轻微的心动过速,但低血压更严重;当催产素与环丙烷麻醉同时使用时,曾观察到孕妇窦性心动过缓伴房室节律异常。

催产素可引起静脉痉挛,导致硫喷妥钠在外周积聚,从而延迟硫喷妥钠麻醉的诱导;然而,这种相互作用尚未得到最终证实。据报道,催产素。

10 mM 0.0993 mL 0.4964 mL 0.9929 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。

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) 。
