• 用途

  メサラジン（Mesalazine）とは抗炎症薬の一つで、潰瘍性大腸炎、クローン病の炎症を治療するのに使用される。5-アミノサリチル酸（5-ASA）とも言われる。結核の治療薬パラアミノサリチル酸（4-アミノサリチル酸、PAS）の位置異性体。 元来使われていたサラゾスルファピリジンの副作用を解消するために開発された。サラゾスルファピリジンの成分のうち副作用の原因となっていたスルファピリジンを除き、有効成分5-アミノサリチル酸のみを取り出した治療薬。

• 用途

• 説明

  5-Aminosalicylic acid (5-ASA), also known as mesalazine or mesalamine, is a metabolite and potential pharmacologically active component of sulphasalazine, a drug used in the treatment of Crohn’s disease and ulcerative colitis. However, the mechanism by which this drug works has not been established. In whole blood assays, 5-ASA proves to be a weak, non-selective inhibitor of both COX-1 and COX-2 with IC50 values of 410 and 61 μM, respectively. In ionophore-stimulated colonic mucosal cells, 1 mM 5-ASA does not inhibit prostaglandin E2 (PGE2) production, but does reduce leukotriene B4 (LTB4) synthesis approx. 50%. In ionophore-stimulated human leukocytes, 400 μM 5-ASA reduces LTB4 production approximately 20%. 5-ASA does not inhibit 15-hydroxy PGDH at concentrations up to 50 μM.

• 化学的特性

  Off-White to pink crystals, melting point about 280 ℃ (decomposition). Soluble in hydrochloric acid, slightly soluble in hot water, and slightly bath in cold water or ethanol. In the manufacture of light-sensitive paper, azo and sulfur dyes.

• 使用

  5-Aminosalicylic acid is used in the preparation of gastrointestinal anti-inflammatory agents. It is a metabolite of sulfasalazine. It acts as a drug involved in the treatment of Crohn's disease and ulcerative colitis. Further, it is used to make dyes and light-sensitive papers.

• 製造方法

  Preparation by reduction of m-nitrobenzoic acid with Zn dust and HCl.

• 主な応用

  5-Aminosalicylic acid (5-ASA) has been used to synthesize 5-formyl-aminosalicylate-inulin to quantify its release during in vitro digestion and fermentation and compare the in vitro fermentation properties of the conjugated inulin to native inulin. It is also used in cell adhesion assay to study its effects on E-cadherin glycosylation and membranous turnover. This compound is used to evaluate its effects on the neutrophilic inflammation index (NII) phenotype to study the effectiveness of the high cholesterol diet-gut inflammation (HCD-GI) platform. 5-Aminosalicylic acid is a peroxidase substrate suitable for use in ELISA procedures. This substrate produces a soluble end product that is brown in color and can be read spectrophotometrically at 450 nm. The reaction may be stopped with 3 N NaOH and read at 550 nm.

• 定義

  ChEBI: Mesalamine is a monohydroxybenzoic acid that is salicylic acid substituted by an amino group at the 5-position. It has a role as a non-steroidal anti-inflammatory drug. It is an aromatic amine, an amino acid, a member of phenols, a monocarboxylic acid and a monohydroxybenzoic acid. It is functionally related to a salicylic acid. It is a conjugate acid of a mesalaminate(1-).

• 一般的な説明

  Odorless white to pinkish crystals or purplish-tan powder. Aqueous solutions acidic (pH approximately 4.1 at 0.8 mg/L water) .

• 空気と水の反応

  Sensitive to moisture. Water insoluble.

• 反応プロフィール

  5-Aminosalicylic acid is incompatible with acids, acid chlorides, acid anhydrides, chloroformates and strong oxidizers.

• 火災危険

  Flash point data for 5-Aminosalicylic acid are not available; however, 5-Aminosalicylic acid is probably combustible.

• 副作用

  5-Aminosalicylic acid (5-ASA) is widely used to treat ulcerative colitis and is better tolerated than sulfadiazine. Common side effects of 5-ASA include nausea, vomiting, abdominal pain, headache, and rash. 5-ASA-induced myocarditis is a rare side effect with only a few case reports. 5-ASA-induced myocarditis usually occurs within 2-4 weeks of medication and causes chest pain and dyspnea. In addition, 5-ASA can aggravate bloody diarrhea in patients with Crohn's disease, which may be accompanied by decreased appetite or hair loss, and is generally uncommon.

• 安全性プロファイル

  Poison by intraperitoneal route.Moderately toxic by ingestion. Human systemic effects byingestion: hypermotility, diarrhea, dermatitis, increasedbody temperature. When heated to decomposition it emitstoxic fumes of NOx.

• 純化方法

  It crystallises as needles from H2O containing a little NaHSO3 to avoid aerial oxidation to the quinone-imine. The Me ester gives needles from *C6H6, m 96o, and the hydrazide has m 180-182o (from H2O). [Fallab et al. Helv Chim Acta 34 26 1951, Shavel J Amer Pharm Assoc 42 402 1953, Beilstein 14 IV 2058.]
