用途吸入ステロイド薬気道の炎症を抑制し，喘息症状を改善する

使用Fluticasone Propionate is a derivative of Flumethasone, a glucocorticoid that has antiallergic, anti-asthmatic, and anti-inflammatory properties. It is used in the treatment of seasonal rhinitis and asthma. Compared to beclomethasone dipropionate, fluticasone propionate is reported to have a comparable side effect profile, but twice the activity in the treatment of asthma.

一般的な説明Fluticasone Propionate is the propionate salt form of fluticasone, a synthetic trifluorinated glucocorticoid receptor agonist with antiallergic, antiinflammatory and antipruritic effects. Binding and activation of the glucocorticoid receptor results in the activation of lipocortin that in turn inhibits cytosolic phospholipase A2, which triggers cascade of reactions involved in synthesis of inflammatory mediators, such as prostaglandins and leukotrienes. Secondly, mitogen-activated protein kinase (MAPK) phosphatase 1 is induced, thereby leads to dephosphorylation and inactivation of Jun N-terminal kinase directly inhibiting c-Jun mediated transcription. Finally, transcriptional activity of nuclear factor (NF)-kappa-B is blocked, thereby inhibits the transcription of cyclooxygenase 2, which is essential for prostaglandin production.

製造方法Fluticasone propionate, synthesized by Glaxo Wellcome and launched in 1993, is a trifluorinated glucocorticosteroid. It shows good topical antiinflammatory activity and is commonly used as a safe and effective inhaled treatment for asthma and allergic rhinitis.Fluticasone propionate can be synthesized from 9 by using BrCH2F,2a ClCH2F,5a or S-(monofluoromethyl) diarylsulfonium tetrafluoroborate 5f,g directly. Using BrCH2F can get an ideal yield; however, BrCH2F is costly and will destroy to the ozone layer. In addition, 9 reacted with BrCH2Cl or Br2CH2 and then by an anion exchange with AgF,2c,5e KF, or tetrabutylammonium fluoride5b to afford 1 in a low yield.Improved Synthesis of Fluticasone Propionate

定義ChEBI: Fluticasone propionate is a trifluorinated corticosteroid that consists of 6alpha,9-difluoro-11beta,17alpha-dihydroxy-17beta-{[(fluoromethyl)sulfanyl]carbonyl}-16-methyl-3-oxoandrosta-1,4-diene bearing a propionyl substituent at position 17; has anti-inflammatory, anti-asthmatic and anti-allergic activity. It has a role as an anti-allergic agent, an anti-asthmatic drug, an anti-inflammatory drug, a dermatologic drug, a bronchodilator agent and an adrenergic agent. It is a corticosteroid, a steroid ester, an 11beta-hydroxy steroid, a propanoate ester, a fluorinated steroid, a thioester and a 3-oxo-Delta(1),Delta(4)-steroid. It derives from a fluticasone. It derives from a hydride of an androstane.
