一般說明

Aldosterone plays a significant role in the multi-factorial regulation of salt, potassium, blood pressure, and acid-base balance. It is also involved in maternal volume expansion during fetal development to support fetal perfusion and may contribute to the increased expression of placental growth factors. While its primary activity is associated with the kidney, aldosterone can also interact with mineralocorticoid receptors in other tissues such as the gastrointestinal tract, respiratory epithelium, myocardium, and vascular smooth muscle.[1] Aldosterone antagonists or mineralocorticoid receptor antagonists (MRAs) can be beneficial for patients with various clinical conditions, including primary aldosteronism (PA), primary and resistant hypertension, heart failure (HF), and chronic kidney disease (CKD).[2]

應用

醛固酮已被用于:
  • 作为足细胞培养的RPMI-1640培养基补充,以测试其在肥胖相关肾小球病(ORG)中的致病性[3]
  • 结合盐诱导小鼠肾损伤[4]
  • 刺激原发性肝窦内皮细胞(LSEC)和小鼠醛固酮增多症模型的产生[5]

醛固酮的D-异构体被认为是具有生物活性的异构体。

生化/生理作用

醛固酮是一种具有生物活性的醛固酮异构体;肾上腺激素由肾上腺皮质产生的一种矿物质皮质激素。它可以诱导尿中K+排出,肾中Na+再吸收。[6]它由促肾上腺皮质激素(ACTH)产生,对维持远端小管的钠稳态至关重要。[7]醛固酮结合到矿糖皮质激素受体,可调节血管系统和诱导肾损害。[8]它有助于慢性肾脏疾病(CKD)的进展。[4]醛固酮是肾素-血管紧张素-醛固酮系统(RAAS)的一部分。[5]

其他說明

以醛和半缩醛的平衡混合物形式存在。
