N-[4-[[(2,4-ジアミノプテリジン-6-イル)メチル]アミノ]ベンゾイル]-L-グルタミン酸 化学特性,用途語,生産方法

• 外観

  白色～くすんだ黄色粉末～結晶

• 化学的特性

  Aminopterin is a white to yellow powder; commonly used as the dihydrate which forms clustersof yellow needles

• 使用

  Aminopterin has been used in the production of anti- neurogranin antibodies.

• 定義

  ChEBI: 4-aminofolic acid is a dicarboxylic acid. It has a role as a mutagen and an EC 1.5.1.3 (dihydrofolate reductase) inhibitor. It is functionally related to a folic acid.

• 一般的な説明

  Clusters of yellow needles. Used as a rodenticide, medicine and rodenticide. Not registered as a rodenticide in the U.S.

• 健康ハザード

  An antimetabolite; antagonizes the utilization of folic acid by the body. Highly toxic by ingestion.

• 作用機序

  Aminopterin is an amino derivative of folic acid which binds competitively to the dihydrofolate reductase enzyme to block tetrahydrofolate synthesis. Tetrahydrofolate is essential in the production of purines and pyrimadines, thus it's deficiency results in a reduction of DNA, RNA and protein synthesis.

• 安全性プロファイル

  Poison by ingestion and intraperitoneal routes. Human and experimental teratogenic data. Other experimental reproductive effects. Mutation data reported. Human systemic effects by ingestion: gastrointestinal. Questionable carcinogen with experimental tumorigenic data. When heated to decomposition it emits toxic fumes of NOx,.

• 職業ばく露

  Aminopterin is used as a medicine (as a folic acid antagonist), rodenticide, and agricultural chemical.

• 輸送方法

  UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required

• 純化方法

  Purify aminopterin by recrystallisation from H2O. It has properties similar to those of methotrexate (above). It has UV at max 244, 290 and 355nm ( 18600, 21300 and 12000) in H2O at pH 1; 260, 284 and 370nm ( 28500, 26400 and 8600) in H2O at pH 13. [Seeger et al. J Am Chem Soc 71 1753 1949, Angier & Curran J Am Chem Soc 8 1 2814 1959, Blakley The Biochemistry of Folic Acid and Related Pteridines, North-Holland Publ Co., Amsterdam, NY, pp 157-163 1969.] For small quantities, chromatograph it on DEAE cellulose with a linear gradient of ammonium bicarbonate pH 8 and increase the molarity from 0.1 to 0.4. Monitoring is by following the UV absorption of the fractions. For larger quantities, a near boiling solution of aminopterin (5g) in H2O (400mL) is slowly treated with small portions of MgO powder (~0.7g, calcined magnesia) with vigorous stirring until a small amount of MgO remained undissolved and the pH rises from 3-4 to 7-8. Charcoal (1g) is added to the hot solution and filtered immediately through a large sintered glass funnel of medium porosity and lined with a hot wet pad of Celite (~2-3 mm thick). The filtrate is cooled in ice, and the crystals of the Mg salt are collected by filtration and recrystallised from boiling H2O (200mL). The crystals are washed with EtOH and dried in vacuo. The Mg salt is redissolved in boiling H2O (200mL) and carefully acidified with vigorous agitation with AcOH (2mL). Pure aminopterin (3g) separates in fine yellow needles (dihydrate) which are easily filtered. The solid is washed with cold H2O, then Me2CO and dried in vacuo. If a trace of impurity is still present as shown by DEAE cellulose chromatography or TLC, repetition of the process will remove it; see UV above.

• 廃棄物の処理

  It is inappropriate and possibly dangerous to the environment to dispose of expired or wastepharmaceuticals by flushing them down the toilet or discarding them to the trash. Household quantities of expired or waste pharmaceuticals may be mixed with wet cat litter or coffee grounds, double-bagged in plastic, discard in trash. Larger quantities shall carefully take into consideration applicable DEA, EPA, and FDA regulations. If possible return the pharmaceutical to the manufacturer for proper disposal being careful to properly label and securely package the material. Alternatively, the waste pharmaceutical shall be labeled, securely packaged and transported by a state licensed medical waste contractor to dispose by burial in a licensed hazardous or toxic waste landfill or incinerator
