一般描述
胆钙化醇作为一种激素前体，因为它需要两个代谢阶段：首先是 25-羟胆钙化醇；然后加入 1α，25-二羟胆钙化醇。一个单位（U.S.P. 或国际）定义为 USP 维生素 D 参考标准中含有 0.025 μg 维生素D3 的活性。
胆钙化醇来源于饮食或皮肤接触紫外线。口服维生素 D3 容易被吸收，并储存在脂肪组织中。
应用
- Alterations in regulators of the renal-bone axis, inflammation and iron status in older people with early renal impairment and the effect of vitamin D supplementation.: This study delves into the significant roles of cholecalciferol in modulating the renal-bone axis, inflammatory responses, and iron metabolism in elderly patients with renal impairment. Through vitamin D supplementation, researchers observed pivotal changes that could guide future therapeutic strategies (Christodoulou M et al., 2024).
- Investigating the effects of 25-hydroxyvitamin D3 on clinical outcomes in multiple sclerosis patients: A randomized, double-blind clinical trial- a pilot study.: This clinical trial assesses the efficacy of cholecalciferol in improving the health outcomes of patients with multiple sclerosis. The use of cholecalciferol potentially enhances neurological function and reduces disease progression, illustrating its vital role in neurodegenerative disease management (Maghbooli Z et al., 2024).
- Vitamin D regulates COVID-19 associated severity by suppressing the NLRP3 inflammasome pathway.: This pivotal research links cholecalciferol to the reduction of COVID-19 severity through its regulatory effects on the NLRP3 inflammasome pathway. The findings underscore the potential of vitamin D as a modulatory agent in the immune response against viral infections (Khalil B et al., 2024).
- Effects of Vitamin D Supplementation on Central Hemodynamic Parameters and Autonomic Nervous System in Obese or Overweight Individuals.: This randomized controlled trial explores how cholecalciferol supplementation can affect cardiovascular and autonomic functions in obese or overweight patients, providing insights into its benefits beyond bone health and into cardiovascular regulation (Faria ACC et al., 2024).
生化/生理作用
在慢性肾病中经常观察到维生素 D 的缺乏。
维生素 D 借以发挥作用的受体是配体依赖性转录因子超家族的成员。调控正常细胞和癌细胞的增殖和分化。对乳腺癌、结肠癌和前列腺癌细胞具有抗增殖和抗转移作用。肠和骨骼中的活化维生素 D 受体维持着钙的吸收和平衡。
储存及稳定性
胆钙化醇 C9756 在氩气下包装。如果未开封储存在 2-8°C 且避光，则本产品可以稳定保存至少三年。未使用的部分应储存在氮气或氩气下。在冰箱温度下，在棕色-抽真空安瓿中储存一年后，变质可忽略不计。它会在几天内被潮湿的空气氧化和灭活。

It is increasingly recognized that excessive glucocorticoids induce fetal intrauterine growth restriction (IUGR). Placental 11β-hydroxysteroid dehydrogenase 2 (11β-HSD2), a glucocorticoid-catalyzing enzyme, prevents active glucocorticoids from maternal circulation into the fetus, thus protecting against IUGR. Previous studies demonstrated gestational LPS exposure

Vitamin D deficiency is a risk factor for arterial hypertension, but randomized controlled trials showed mixed effects of vitamin D supplementation on blood pressure (BP). We aimed to evaluate whether vitamin D supplementation affects 24-hour systolic ambulatory BP monitoring values

Diabetic retinopathy is a vision-threatening microvascular complication of diabetes and is one of the leading causes of blindness. Oxidative stress and inflammation play a major role in its pathogenesis, and new therapies counteracting these contributors could be of great interest.
