The name mineralocorticoid derives from early observations that these hormones were involved in the retention of sodium, a mineral. The primary endogenous mineralocorticoid is aldosterone , although a number of other endogenous hormones (including progesterone [ 1 ] and deoxycorticosterone ) have mineralocorticoid function.
Corticosteroids are a class of steroid hormones that are produced in the adrenal cortex of vertebrates, as well as the synthetic analogues of these hormones.Two main classes of corticosteroids, glucocorticoids and mineralocorticoids, are involved in a wide range of physiological processes, including stress response, immune response, and regulation of inflammation, carbohydrate metabolism ...
11-Deoxycorticosterone (DOC), or simply deoxycorticosterone, also known as 21-hydroxyprogesterone, as well as desoxycortone , deoxycortone, and cortexone, [1] [2] is a steroid hormone produced by the adrenal gland that possesses mineralocorticoid activity and acts as a precursor to aldosterone. [3] It is an active (Na+-retaining ...
The glucocorticoid activity of progesterone and 17α-hydroxyprogesterone is very weak (>100-fold less than that of cortisol). [1] The above list includes precursors and intermediates in corticosteroid biosynthesis.
Aldosterone is the main mineralocorticoid steroid hormone produced by the zona glomerulosa of the adrenal cortex in the adrenal gland. [4] [5] It is essential for sodium conservation in the kidney, salivary glands, sweat glands, and colon. [6]
The activity of mineralocorticoid antagonists is dependent on the presence of a y-lactone ring on the C-17 position. The C-7 position is also important for activity as substituents there sterically hinder the interaction of C-7-unsubstituted agonists such as aldosterone. [7] Antimineralocorticoids and highlighted groups that are important for ...
Synthetic glucocorticoids are similar to endogenous steroids in metabolism but differ in affinity for glucocorticoid and mineralocorticoid receptors, affinity for protein-binding, rate of elimination, and metabolic products. [4] Oral methylprednisolone is readily absorbed from the gastrointestinal tract with a bioavailability of 89.9%. [38]
Fludrocortisone is a corticosteroid and acts as a powerful mineralocorticoid, along with some additional but comparatively very weak glucocorticoid activity. [12] Relative to cortisol, it is said to have 10 times the glucocorticoid potency but 250 to 800 times the mineralocorticoid potency.
