Antracen
Anthracene is a solid polycyclic aromatic hydrocarbon (PAH) of formula C14H10, consisting of three fused benzene rings. It is a component of coal tar. Anthracene is used in the production of the red dye alizarin and other dyes. Anthracene is colorless but exhibits a blue (400–500 nm peak) fluorescence under ultraviolet radiation. Occurrence and production Coal tar, which contains around 1.5% anthracene, remains a major source of this material. Common impurities are phenanthrene and carbazole. The mineral form of anthracene is called freitalite and is related to a coal deposit. A classic laboratory method for the preparation of anthracene is by cyclodehydration of o-methyl- or o-methylene-substituted diarylketones in the so-called Elbs reaction, for example from ''o''-tolyl phenyl ketone. Reactions Reduction Reduction of anthracene with alkali metals yields the deeply colored radical anion salts M+ nthracenesup>− (M = Li, Na, K). Hydrogenation gives 9,10-dihydroanthr ...

Tazarotene
Tazarotene, sold under the brand name Tazorac, among others, is a third-generation prescription topical retinoid. It is primarily used for the treatment of plaque psoriasis and acne. Tazarotene is also used as a therapeutic for photoaged and photodamaged skin. Tazarotene is a member of the acetylenic class of retinoids. It is available as a generic medication. Medical uses Tazarotene is most commonly used topically to treat acne vulgaris and psoriasis. Like other topical retinoids, such as tretinoin and adapalene, tazarotene can be combined with benzoyl peroxide or an oral antibiotic, such as clindamycin or dapsone, for the treatment of acne. This results in increased efficacy compared to tazarotene monotherapy. For psoriasis, a combination therapy of tazarotene and a mid- to high-potency corticosteroid is more effective than either treatment alone. Tazarotene can also be used for the treatment of photodamaged skin. It can reduce the clinical and histological signs of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acitretin
Acitretin (trade names Soriatane and Neotigason) is a second-generation retinoid. It is taken orally, and is typically used for psoriasis. Acitretin is an oral retinoid used in the treatment of severe resistant psoriasis. Because of the potential for problems and severe side effects it is generally used in only very severe cases of psoriasis that have been unresponsive to other treatments. It binds to nuclear receptors that regulates gene transcription. They induce keratinocyte differentiation and reduce epidermal hyperplasia, leading to the slowing of cell reproduction. Acitretin is readily absorbed and widely distributed after oral administration. A therapeutic effect occurs after two to four weeks or longer. Patients who have received the medication are advised against giving blood for at least three years due to the risk of birth defects. Adverse effects Acitretin is highly teratogenic and noted for the possibility of severe birth defects. It should not be used by pregnan ...

Etretinate
Etretinate (trade name Tegison) is a medication developed by Hoffmann–La Roche that was approved by the FDA in 1986 to treat severe psoriasis. It is a second-generation retinoid. It was subsequently removed from the Canadian market in 1996 and the United States market in 1998 due to the high risk of birth defects. It remains on the market in Japan as Tigason. Pharmacology Etretinate is a highly lipophilic, aromatic retinoid. It is stored and released from adipose tissue, so its effects can continue long after dosage stops. It is detectable in the plasma for up to three years following therapy. Etretinate has a low therapeutic index and a long elimination half-life (''t''1/2) of 120 days, which make dosing difficult. Etretinate has been replaced by acitretin, the free acid (without the ethyl ester). While acitretin is less lipophilic and has a half-life of only 50 hours, it is partly metabolized to etretinate in the body, so that it is still a long-acting teratogen and preg ...

Psoriasis
Psoriasis is a long-lasting, noncontagious autoimmune disease characterized by raised areas of abnormal skin. These areas are red, pink, or purple, dry, itchy, and scaly. Psoriasis varies in severity from small, localized patches to complete body coverage. Injury to the skin can trigger psoriatic skin changes at that spot, which is known as the Koebner phenomenon. The five main types of psoriasis are plaque, guttate, inverse, pustular, and erythrodermic. Plaque psoriasis, also known as psoriasis vulgaris, makes up about 90% of cases. It typically presents as red patches with white scales on top. Areas of the body most commonly affected are the back of the forearms, shins, navel area, and scalp. Guttate psoriasis has drop-shaped lesions. Pustular psoriasis presents as small, noninfectious, pus-filled blisters. Inverse psoriasis forms red patches in skin folds. Erythrodermic psoriasis occurs when the rash becomes very widespread, and can develop from any of the other types ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retinoid
The retinoids are a class of chemical compounds that are vitamers of vitamin A or are chemically related to it. Retinoids have found use in medicine where they regulate epithelial cell growth. Retinoids have many important functions throughout the body including roles in vision, regulation of cell proliferation and differentiation, growth of bone tissue, immune function, and activation of tumor suppressor genes. Research is also being done into their ability to treat skin cancers. Currently, alitretinoin (9-''cis''-retinoic acid) may be used topically to help treat skin lesions from Kaposi's sarcoma, and tretinoin (all-''trans''- retinoic acid) is used to treat acute promyelocytic leukemia. Types There are four generations of retinoids: * First generation include retinol, retinal, tretinoin ( retinoic acid), isotretinoin, and alitretinoin * Second generation include etretinate and its metabolite acitretin * Third generation include adapalene, bexarotene, and tazarotene * ...

Bergapten
Bergapten (5-methoxypsoralen) is a naturally-occurring organic chemical compound produced by numerous plant species, especially from the carrot family Apiaceae and the citrus family Rutaceae. For example, bergapten has been extracted from 24 species of the genus '' Heracleum'' in the family Apiaceae. Cited by Mitchell and Rook (1979). In the family Rutaceae, various ''Citrus'' species contain significant amounts of bergapten, especially the bergamot orange, the micrantha, and certain varieties of lime and bitter orange. Bergapten belongs to a class of chemical compounds known as the furanocoumarins. In 1834, Kalbrunner isolated 5-methoxypsoralen from bergamot essential oil, hence the common name "bergapten". It was the first furanocoumarin to be isolated and identified. Toxicity Bergapten is a derivative of psoralen, the parent compound of a family of naturally-occurring organic compounds known as the linear furanocoumarins (so called since they exhibit a linear chemical ...

Dithranol
Dithranol ( INN) or anthralin (USAN and former BAN) is a hydroxyanthrone, anthracene derivative, medicine applied to the skin of people with psoriasis. It is available as creams, ointment or pastes in 0.1 to 2% strengths (Drithocreme, Dithrocream, Zithranol-RR, Micanol, Psorlin, Dritho-Scalp, Anthraforte, Anthranol and Anthrascalp). The terms dithranol and anthralin are sometimes used synonymously. Medical uses Dithranol has a slower onset of action in controlling psoriasis, typically several weeks, compared to glucocorticoid steroids, but is without the potential for rebound reaction on withdrawal. It cannot be used on the face or genitalia. There is some tentative evidence that anthralin might be useful for alopecia areata. Side effects It temporarily stains the skin a yellowy-brown and permanently stains clothing fabrics and other materials such as ceramic sinks. It may cause a local burning sensation and irritation; this may be minimised by careful attention to the details of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calcitriol
Calcitriol is the active form of vitamin D, normally made in the kidney. It is also known as 1,25-dihydroxycholecalciferol. It is a hormone which binds to and activates the vitamin D receptor in the nucleus of the cell, which then increases the expression of many genes. Calcitriol increases blood calcium (Ca2+) mainly by increasing the uptake of calcium from the intestines. It can be given as a medication for the treatment of low blood calcium and hyperparathyroidism due to kidney disease, low blood calcium due to hypoparathyroidism, osteoporosis, osteomalacia, and familial hypophosphatemia, and can be taken by mouth or by injection into a vein. Excessive amounts or intake can result in weakness, headache, nausea, constipation, urinary tract infections, and abdominal pain. Serious side effects may include high blood calcium and anaphylaxis. Regular blood tests are recommended after the medication is started and when the dose is changed. Calcitriol was identified as the activ ...
