生物活性&实验参考方法
体外研究 (In Vitro)
药物化合物包括碳、氢和其他元素的稳定重同位素,在药物开发过程中主要作为定量示踪剂。由于氘化可能会影响药物的药代动力学和代谢特性,因此值得关注[1]。
药代性质 (ADME/PK)
吸收、分布和排泄
如果脂肪吸收正常,胆钙化醇很容易从小肠被吸收。此外,胆汁对于吸收也是必需的。特别是,近期研究确定了维生素D吸收的几个方面,例如:a) 胆钙化醇的25-羟基维生素D代谢物比非羟基形式的胆钙化醇吸收率更高;b) 与胆钙化醇一起摄入的脂肪量似乎对其生物利用度影响不大;c) 年龄似乎不影响维生素D胆钙化醇的吸收。
观察发现,摄入的胆钙化醇及其代谢物主要通过胆汁和粪便排出。
研究表明,在49名肾移植患者中,补充胆钙化醇后的平均中心分布容积约为237升。
研究表明,在49名肾移植患者中,补充胆钙化醇后的平均清除率约为2.5升/天。
易于从小肠(近端或远端)吸收;胆钙化醇的吸收速度和完全性可能优于麦角钙化醇。
排泄途径:胆汁/肾脏。/维生素D及其类似物/
如果脂肪吸收正常,许多维生素D类似物口服后可迅速被胃肠道吸收。麦角钙化醇的吸收需要胆汁的存在,而患有肝脏、胆道或胃肠道疾病(例如克罗恩病、惠普尔病、乳糜泻)的患者,其胃肠道吸收程度可能会降低。由于维生素D是脂溶性的,它会被整合到乳糜微粒中,并通过淋巴系统吸收;大约80%的摄入维生素D似乎通过这种机制被全身吸收,主要在小肠中吸收。虽然一些证据表明老年人对维生素D的肠道吸收可能会降低,但其他证据并未显示治疗剂量下维生素D的胃肠道吸收存在具有临床意义的年龄相关性改变。目前尚不清楚衰老是否会改变胃肠道对生理剂量维生素D的吸收。/维生素D类似物/
吸收后,麦角钙化醇和胆钙化醇通过淋巴乳糜微粒进入血液,然后主要与一种特定的α-球蛋白(维生素D结合蛋白)结合。麦角钙化醇和胆钙化醇的羟基化代谢物也与相同的α-球蛋白结合循环。25-羟基化的麦角钙化醇和胆钙化醇可在脂肪和肌肉中长期储存。维生素D经胸导管从淋巴系统或皮肤进入体循环后,会在数小时内积聚在肝脏中。

代谢/代谢物
在肝脏中,胆钙化醇在维生素D-25-羟化酶的作用下羟基化为骨化二醇(25-羟基胆钙化醇)。在肾脏中,骨化二醇随后作为1-α-羟化酶的底物,生成骨化三醇(1,25-二羟基胆钙化醇),即维生素D3的生物活性形式。
胆钙化醇和麦角钙化醇的代谢活化分两步进行,第一步在肝脏,第二步在肾脏。骨化二醇的代谢活化发生在肾脏;二氢速甾醇、阿法骨化醇和多西骨化醇则在肝脏中活化。
据报道,胆钙化醇和麦角钙化醇的主要循环代谢产物——25-羟基胆钙化醇(骨化二醇)和25-羟基麦角钙化醇的正常血浆总浓度(即25-羟基维生素D)范围为8-80 ng/mL,具体数值取决于所用检测方法,并会随紫外线照射而变化。根据地理位置的不同(例如,南加州的数值会高于马萨诸塞州),通常报道的正常值下限范围为8-15 ng/mL。
在肝脏中,麦角钙化醇和胆钙化醇在维生素D 25-羟化酶的作用下,于线粒体中转化为其25-羟基衍生物。维生素D 25-羟化酶的活性在肝脏中受维生素D及其代谢产物浓度的调节;因此,与维生素D的累积生成或摄入量相比,日光照射或摄入维生素D后,全身循环中25-羟基代谢产物的增加相对较小。由于储存在脂肪组织中或在肝脏中代谢,血清中未羟基化的维生素D浓度持续时间较短。在肾脏中,这些代谢产物在维生素D 1-羟化酶的作用下,于1位进一步羟基化,生成其活性形式:1,25-二羟基胆钙化醇(骨化三醇)和1,25-二羟基麦角钙化醇。维生素D 1-羟化酶的活性需要分子氧、镁离子和苹果酸,主要受甲状旁腺激素(PTH)调节,而PTH又受血清钙和磷酸盐浓度的影响,可能还受循环中1,25-二羟基麦角钙化醇和1,25-二羟基胆钙化醇浓度的影响。其他激素(例如皮质醇、雌激素、催乳素和生长激素)也可能影响胆钙化醇和麦角钙化醇的代谢。
负责维生素D 25-羟化的肝脏酶系统(维生素D-25羟化酶)与匀浆的微粒体和线粒体组分相关,需要NADPH(还原型烟酰胺腺嘌呤二核苷酸磷酸)和分子氧。肾脏中负责 25-羟基维生素 D (25-OHD) 1-羟基化的酶系统(25-OHD-1-α-羟化酶)与近端小管的线粒体相关。它是一种混合功能氧化酶,需要分子氧和 NADPH 作为辅因子。细胞色素 P450(一种黄素蛋白)和铁氧还蛋白是该酶复合物的组成部分。
生物半衰期
目前,一些资料显示胆钙化醇的半衰期约为 50 天,而另一些资料则指出骨化三醇(1,25-二羟基维生素 D3)的半衰期约为 15 小时,骨化二醇(25-羟基维生素 D3)的半衰期约为 15 天。此外,维生素D的半衰期似乎会因个体间维生素D结合蛋白浓度和基因型的差异而有所不同。维生素D在血浆中的半衰期为19至25小时,但会在脂肪组织中长期储存。……25-羟基维生素D衍生物的生物半衰期为19天……据估计,人体内骨化三醇(1,25-二羟基维生素D)的血浆半衰期为3至5天……
毒性/毒理 (Toxicokinetics/TK)
蛋白质结合
已记录的胆钙化醇蛋白质结合率为 50% 至 80%。具体而言,在血浆中,维生素 D3(来自饮食或皮肤)与肝脏产生的维生素 D 结合蛋白 (DBP) 结合,以便运输至肝脏。最终,到达肝脏的维生素 D3 被 25-羟基化,这种 25-羟基胆钙化醇在血浆循环过程中与 DBP(α2-球蛋白)结合。
毒性数据

相互作用
皮质类固醇可拮抗维生素 D 类似物的作用。 /维生素D类似物/
在甲状旁腺功能减退患者中,同时服用噻嗪类利尿剂和药理剂量的维生素D类似物可能导致高钙血症,这种高钙血症可能是短暂且自限性的,也可能需要停用维生素D类似物。甲状旁腺功能减退患者中噻嗪类利尿剂引起的高钙血症可能是由于骨骼中钙的释放增加所致。/维生素D类似物/
过量使用矿物油可能会干扰肠道对维生素D类似物的吸收。/维生素D类似物/
奥利司他可能导致脂溶性维生素(例如维生素D类似物)的胃肠道吸收减少。服用任何剂量的奥利司他与服用维生素D类似物之间(之前或之后)至少应间隔2小时。/维生素D类似物/

治疗用途
骨密度保护剂;维生素
药物(兽用):营养因子(抗佝偻病药)
特定维生素D类似物的治疗剂量用于治疗与多种疾病相关的慢性低钙血症、低磷血症、佝偻病和骨营养不良,这些疾病包括慢性肾功能衰竭、家族性低磷血症和甲状旁腺功能减退症(术后、特发性或假性甲状旁腺功能减退症)。一些类似物已被发现可以降低伴有甲状旁腺功能亢进的肾性骨营养不良患者体内升高的甲状旁腺激素浓度。理论上,任何维生素D类似物均可用于治疗上述疾病,但由于其药理特性不同,某些类似物在特定情况下可能比其他类似物更有效。对于肾功能衰竭患者,通常首选阿法骨化醇、骨化三醇和二氢速甾醇,因为这些患者自身合成骨化三醇的能力受损,因此疗效更可预测。此外,这些药物的半衰期较短,毒性反应更容易控制(高钙血症逆转更快)。麦角钙化醇可能并非治疗家族性低磷血症或甲状旁腺功能减退症的首选药物,因为所需的大剂量存在过量和高钙血症的风险;此时二氢速甾醇和骨化三醇可能更合适。 /美国产品标签包含/
药物警告
研究表明,老年人可能由于皮肤产生维生素D3前体的能力下降、日照减少、肾功能受损或维生素D吸收障碍而增加对维生素D的需求。
剂量不超过生理需求的维生素D类似物通常无毒。然而,一些婴儿以及患有结节病或甲状旁腺功能减退症的患者可能对维生素D类似物更加敏感。/维生素D类似物/
急性或慢性服用过量维生素D类似物,或对生理剂量的麦角钙化醇或胆钙化醇反应增强,可能导致维生素D过量症,表现为高钙血症。/维生素D类似物/
据报道,长期服用维生素D类似物治疗的甲状旁腺功能减退症患者也出现肾功能下降,但无高钙血症。在开始使用维生素D类似物治疗之前,必须控制血清磷酸盐浓度。为避免异位钙化,血清钙(mg/dL)与磷(mg/dL)的比值不应超过70。由于服用维生素D类似物可能会增加磷酸盐的吸收,肾功能衰竭患者可能需要调整用于减少磷酸盐吸收的含铝抗酸剂的剂量。/维生素D类似物/

药效学
维生素D两种主要生物活性代谢物的体内合成分两步进行。维生素D3胆钙化醇(或维生素D2)的第一次羟基化发生在肝脏,生成25-羟基维生素D;第二次羟基化发生在肾脏,生成1,25-二羟基维生素D。这些维生素D代谢物随后促进小肠对钙和磷的吸收,从而提高血清钙和磷的水平,以促进骨骼矿化。反之,这些维生素D代谢物也有助于从骨骼中动员钙和磷,并可能通过肾小管增加钙(或许还有磷)的重吸收。由于肝脏和肾脏需要合成活性维生素D代谢物,因此从服用胆钙化醇到其在体内发挥作用之间需要10到24小时。甲状旁腺激素负责调节肾脏水平的这种代谢。

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 0.5159 mL 2.5796 mL 5.1592 mL
10 mM 0.2580 mL 1.2898 mL 2.5796 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。
