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.
Phytoecdysteroids also appear in many plants mostly as a protection agents (toxins or antifeedants) against herbivore insects. [ 7 ] [ 8 ] Fungi also produce a handful of mycoecdysteroids . [ 9 ] In addition, synthetic ecdysteroid pesticides such as methoxyfenozide have been produced.
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 ...

Common injection sites include the inner surface of the forearm, the upper back, deltoid, thigh, and under the shoulder blade. [1] Injections sites are often chosen for skin thickness, preferring thicker skin.
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. [2]
A variety of synthetic steroids and sterols have also been contrived. Most are steroids, but some nonsteroidal molecules can interact with the steroid receptors because of a similarity of shape. Some synthetic steroids are weaker or stronger than the natural steroids whose receptors they activate. [8] Some examples of synthetic steroid hormones:
Brassinolide, the first brassinosteroid isolated and shown to have biological activity. Brassinosteroids (BRs or less commonly BS) [1] are a class of polyhydroxysteroids that have been recognized as a sixth class of plant hormones and may have utility as anticancer drugs for treating endocrine-responsive cancers by inducing apoptosis of cancer cells and inhibiting cancerous growth.
