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, protein catabolism, blood electrolyte levels, and behavior.
Butyric acid (from Ancient Greek: βούτῡρον, meaning "butter"), also known under the systematic name butanoic acid is a carboxylic acid with the structural formula CH3CH2CH2CO2H. Classified as a carboxylic acid, it is an oily, colorless liquid that is soluble in water, ethanol, and ether. Isobutyric acid (2-methylpropanoic acid) is an isomer. Salts and esters of butyric acid are known as butyrates or butanoates. The acid does not occur widely in nature, but its esters are widespread. It is a common industrial chemical.
Butyrate or butanoate is the traditional name for the conjugate base of butyric acid. The formula of the butyrate ion is C
4H
7O−
2. The name is used as part of the name of esters and salts of butyric acid
Hydrocortisone is the name for the hormone cortisol when supplied as a medication. Uses include conditions such as adrenocortical insufficiency, adrenogenital syndrome, high blood calcium, thyroiditis, rheumatoid arthritis, dermatitis, asthma, and COPD. It is the treatment of choice for adrenocortical insufficiency. It can be given by mouth, topically, or by injection. Stopping treatment after long-term use should be done slowly.
A rash is a change of the human skin which affects its color, appearance, or texture.
Ethyl butyrate, also known as ethyl butanoate, or butyric ether, is an ester with the chemical formula CH3CH2CH2COOCH2CH3. It is soluble in propylene glycol, paraffin oil, and kerosene. It has a fruity odor, similar to pineapple, and is a key ingredient used as a flavor enhancer in processed orange juices. It also occurs naturally in many fruits, albeit at lower concentrations.
ATC code D07Corticosteroids, dermatological preparations is a therapeutic subgroup of the Anatomical Therapeutic Chemical Classification System, a system of alphanumeric codes developed by the World Health Organization (WHO) for the classification of drugs and other medical products. Subgroup D07 is part of the anatomical group D Dermatologicals.
Pentyl butyrate, also known as pentyl butanoate or amyl butyrate, is an ester that is formed when pentanol is reacted with butyric acid, usually in the presence of sulfuric acid as a catalyst. This ester has a smell reminiscent of pear or apricot. This chemical is used as an additive in cigarettes.
Methyl butyrate, also known under the systematic name methyl butanoate, is the methyl ester of butyric acid. Like most esters, it has a fruity odor, in this case resembling apples or pineapples. At room temperature, it is a colorless liquid with low solubility in water, upon which it floats to form an oily layer. Although it is flammable, it has a relatively low vapor pressure, so it can be safely handled at room temperature without special safety precautions.
Hydrocortisone butyrate is a corticosteroid that comes in one of the following forms:
Butyl butyrate, or butyl butanoate, is an organic compound that is an ester formed by the condensation of butyric acid and n-butanol. It is a clear, colorless liquid that is insoluble in water, but miscible with ethanol and diethyl ether. Its refractive index is 1.406 at 20 °C.
Clobetasone (INN) is a corticosteroid used in dermatology, for treating such skin inflammation as seen in eczema, psoriasis and other forms of dermatitis, and ophthalmology. Topical clobetasone butyrate has shown minimal suppression of the hypothalamic–pituitary–adrenal axis.
"To Market, to Market" is the second episode of M*A*S*H. It was first aired on September 24, 1972 and repeated on April 29, 1973. Like many other M*A*S*H episodes, this one parodies army bureaucracy.
Topical steroids are the topical forms of corticosteroids. Topical steroids are the most commonly prescribed topical medications for the treatment of rash, eczema, and dermatitis. Topical steroids have anti-inflammatory properties, and are classified based on their skin vasoconstrictive abilities. There are numerous topical steroid products. All the preparations in each class have the same anti-inflammatory properties, but essentially differ in base and price.
Hydrocortisone 17-butyrate is a form of hydrocortisone butyrate.
Sodium butyrate is a compound with formula Na(C3H7COO). It is the sodium salt of butyric acid. It has various effects on cultured mammalian cells including inhibition of proliferation, induction of differentiation and induction or repression of gene expression. As such, it can be used in lab to bring about any of these effects. Specifically, butyrate treatment of cells results in histone hyperacetylation, and butyrate itself inhibits class I histone deacetylase (HDAC) activity, specifically HDAC1, HDAC2, HDAC3, and butyrate can be used in determining histone deacetylene in chromatin structure and function. Inhibition of HDAC activity is estimated to affect the expression of only 2% of mammalian genes.
The molecular formula C25H36O6 (molar mass: 432.54 g/mol, exact mass: 432.251189) may refer to:
Domoprednate is a synthetic glucocorticoid corticosteroid which was developed in the late 1970s and 1980s.
