Aldosterone synthase, also called steroid 18-hydroxylase, corticosterone 18-monooxygenase or P450C18, is a steroid hydroxylase cytochrome P450 enzyme involved in the biosynthesis of the mineralocorticoid aldosterone and other steroids. The enzyme catalyzes sequential hydroxylations of the steroid angular methyl group at C18 after initial 11β ...
Aldosterone is the primary of several endogenous members of the class of mineralocorticoids in humans. Deoxycorticosterone is another important member of this class. Aldosterone tends to promote Na + and water retention, and lower plasma K + concentration by the following mechanisms:
Glucocorticoid remediable aldosteronism. Glucocorticoid remediable aldosteronism also describable as aldosterone synthase hyperactivity, is an autosomal dominant disorder in which the increase in aldosterone secretion produced by ACTH is no longer transient. It is a cause of primary hyperaldosteronism.
Steroidogenic enzymes are enzymes that are involved in steroidogenesis and steroid biosynthesis. [2][3][4][5] They are responsible for the biosynthesis of the steroid hormones, including sex steroids (androgens, estrogens, and progestogens) and corticosteroids (glucocorticoids and mineralocorticoids), as well as neurosteroids, from cholesterol ...
15632. Anatomical terminology. [edit on Wikidata] The adrenal cortex is the outer region and also the largest part of the adrenal gland. It is divided into three separate zones: zona glomerulosa, zona fasciculata and zona reticularis. Each zone is responsible for producing specific hormones. It is also a secondary site of androgen synthesis.
Function. 18-Hydroxycorticosterone serves as an intermediate in the synthesis of aldosterone by the enzyme aldosterone synthase in the zona glomerulosa. [6] It is also an intermediate in the biosynthesis of corticosterone. It spontaneously and reversibly converts to various less polar forms and derivatives, some of which serve as precursors to ...
Key:YHGVDZULVMINCJ-UHFFFAOYSA-N. Lorundrostat (developmental name MLS 101) is an aldosterone synthase inhibitor developed by Mineralys Therapeutics for high blood pressure. In clinical trials as an add-on medication for people with uncontrolled hypertension, decreased renin and elevated aldosterone it significantly reduced blood pressure.
Endocrinology. Familial hyperaldosteronism is a group of inherited conditions in which the adrenal glands, which are small glands located on top of each kidney, produce too much of the hormone aldosterone. [1] Excess aldosterone causes the kidneys to retain more salt than normal, which in turn increases the body's fluid levels and causes high ...
