18-Oxocortisol is a derivative of cortisol that is produced by aldosterone synthase (CYP11B2). 18-Oxocortisol is a naturally occurring mineralocorticoid agonist. 18-Oxocortisol is a biomarker in adrenal vein sampling .
In Vivo
Administration of 18-oxocortisol to rats induces a mineralocorticoid-type hypertension with hypokalemia, cardiac and renal enlargement and cardiovascular lesions. Administration of 18-oxocortisol to sheep also causes a rapid increase in blood pressure. However, the doses required for increasing blood pressure are high. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
