| | アンレキサノクス Usage And Synthesis |
| 外観 | 白色～うすい黄色粉末～結晶 | | 効能 | 抗アレルギー薬, メディエーター遊離抑制薬 | | 商品名 | エリックス (千寿製薬) | | 説明 | Amlexanox is an orally-active antiasthmatic agent useful in the treatment of bronchial
asthma and allergy-related sinus disorders. The therapeutic effect of amlexanox appears
to be attributed to its inhibitory actions on leukohiene D4, PAF and histamine. | | 化学的特性 | White Crystalline Solid | | Originator | Takeda (Japan) | | 使用 | Inhibits release of allergic mediators from mast cells. Antiallergic; antiasthmatic | | 定義 | ChEBI: A pyridochromene-derived monocarboxylic acid having an amino substituent at the 2-position, an oxo substituent at the 5-position and an isopropyl substituent at the 7-position. | | Manufacturing Process | A mixture of 2 ml of morpholine, 3 ml of dimethylformamide and 10 ml of
water was heated to 60°C and under stirring the equal molecular quantity of
6-isopropyl-4-oxo-4H-1-benzopyran-3-carbonitrile was added for 5 minutes.
The mixture was heated at that temperature for one hour and the resultant
precipitate was filtered, rained with water recrystallized from acetic acid and
washed with chloroform. By the above procedure was obtained 2-amino-6-
isopropyl-4-oxo-4H-1-benzopyran-3-carboxaldehyde melting at 206°-208°C. A
mixture of 4 ml ethyl cyanoacetate, 50 ml of ethanol, 5 ml of piperidine and
the equal molecular quantity of 2-amino-6-isopropyl-4-oxo-4H-1-benzopyran-
3-carboxaldehyde was refluxed for 30 minutes and, after cooling, the
crystalline precipitate was filtered and washed with chloroform. By above
procedure was obtained ethyl-2-amino-7-isopropyl-1-azaxanthone-3-
carboxylate, melting after recrystallization from ethanol at 243°-244°C. A
mixture of 10 ml of acetic acid and 10 ml of 55% sulfuric acid the equal
molecular quantity and 2-ethyl-amino-7-isopropyl-1-azaxanthone-3-
carboxylate was stirred at 130°C for 4 hours and, after water was added, the
precipitate was collected by filtration and recrystalllized from
dimethylformamide to give the 2-amino-7-(1-methylethyl)-5-oxo-5H-
[1]benzopyrano[2,3-b]pyridine-3-carboxylic acid, melting point 300°C. | | brand name | Aphthasol (Uluru);Solfa. | | Therapeutic Function | Antiulcer (topical) | | 一般的な説明 | Amlexanox is an anti-allergic drug with anti-inflammatory properties. | | Biochem/physiol Actions | Amlexanox elevates the amount of nonsense-containing mRNAs in treated cells and helps to generate full-length proteins effectively. | | 貯蔵 | Store at -20°C | | 参考文献 | 1) Koch et al.
