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 ...
Glucocorticoids are corticosteroids that bind to the glucocorticoid receptor [1] that is present in almost every vertebrate animal cell. The name "glucocorticoid" is a portmanteau ( gluco se + cort ex + ster oid ) and is composed from its role in regulation of glucose metabolism , synthesis in the adrenal cortex , and its steroidal structure ...
Glucocorticoids suppress cell-mediated immunity. They act by inhibiting gene expression of cytokines including Interleukin 1 (IL-1), IL-2, IL-3, IL-4, IL-5, IL-6, IL-8, and TNF-alpha by binding to corticosteroid response elements on DNA. [1] This decrease in cytokine production reduces T cell proliferation. With decreased T cell proliferation ...
Glucocorticoid receptor antagonists: Mifepristone (RU-486) is the primary example of this class, which directly blocks the action of cortisol at its receptor sites. [ 3 ] [ 6 ] Steroid hormones: Dehydroepiandrosterone (DHEA) has been studied for its potential antiglucocorticoid effects.
Most esters of these corticosteroids are not included in this list; for esters, see here instead. The most common structural modifications in synthetic corticosteroids include 1(2)-dehydrogenation, 6α-, 9α-, 16α-, and 16β-substitution (with a halogen or methyl group), 16α,17α-acetonidation, and 17α- and 21-esterification.
Prednisolone is a corticosteroid drug with predominant glucocorticoid and low mineralocorticoid activity, making it useful for the treatment of a wide range of inflammatory and autoimmune conditions [17] such as asthma, [18] uveitis, pyoderma gangrenosum, rheumatoid arthritis, urticaria, [19] angioedema, [19] ulcerative colitis, pericarditis ...
Beclometasone dipropionate, an example of a widely used corticosteroid ester. Note the propionate groups at the C17α and C21α positions (top right corner). This is a list of corticosteroid esters, including esters of steroidal glucocorticoids and mineralocorticoids. [1] [2] [3]
Topical glucocorticoid phobia is a concern or fear about using topical glucocorticoids, which is commonly found among patients with atopic dermatitis and their caregivers. [29] This phenomenon has been identified in more than 15 countries globally, including Canada , France , Japan , the United Kingdom , and the United States . [ 30 ]
