An equianalgesic chart can be a useful tool, but the user must take care to correct for all relevant variables such as route of administration, cross tolerance, half-life and the bioavailability of a drug. [5] For example, the narcotic levorphanol is 4–8 times stronger than morphine, but also has a much longer half-life. Simply switching the ...

18-Hydroxy-11-deoxycorticosterone (also known as 18-OH-DOC, 18,21-dihydroxyprogesterone, and 18,21-dihydroxypregn-4-ene-3,20-dione) is an endogenous steroid and a mineralocorticoid. It is a hydroxylated metabolite of 11-deoxycorticosterone. [1] In rats, conversion of 11-deoxycorticosterone into 18-OH-DOC is catalyzed by the CYP11B3 enzyme. [2]
Cortisone = 17α,21-dihydroxypregn-4-ene-3,11,20-trione; Pregnenolone = pregn-5-en-3β-ol-20-one; Progesterone = pregn-4-ene-3,20-dione; 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 ...
The steroid hormones are referred to by various abbreviations in the biological literature. The purpose of this list is to give commonly used abbreviations for steroid hormones, with supporting references to the literature.
Cortisone is a pregnene (21-carbon) steroid hormone. It is a naturally-occurring corticosteroid metabolite that is also used as a pharmaceutical prodrug . Cortisol is converted by the action of the enzyme corticosteroid 11-beta-dehydrogenase isozyme 2 into the inactive metabolite cortisone, particularly in the kidneys.
The additional gene plays a role in synthesizing 18-oxocortisol by attaching the oxo (=O) functional group to carbon 18 of the steroid nucleus of cortisol. [3] This additional gene also plays a role in the biosynthesis of aldosterone and 18-hydroxycortisol .
Corticosterone, also known as 17-deoxycortisol and 11β,21-dihydroxyprogesterone, [1] is a 21-carbon steroid hormone of the corticosteroid type produced in the cortex of the adrenal glands. In the very rare case of congenital adrenal hyperplasia due to 17α-hydroxylase deficiency cortisol production is blocked.
