The present invention can be used in medical practice specifically in chemical and pharmaceutical production of medicinal agents capable of modulating the immune system. This invention essentially relates to a new medicinal preparation 5-amino-2,3-dihydrophthalazine-1,4-dione sodium salt having immunomodulatory, antiinflammatory, and antioxidant properties. The preparation is obtained from 3-nitro-phthalanhydride by consecutive isolation of intermediate and end products. The intermediate products include 5-nitro-2,3-dihydrophthalazine-1,4-dione and 5-amino-2,3-dihydrophthala2ine-1,4-dione. The reaction between 5-amino-2,3-dihydrophthalazine-1,4-dione and sodium hydroxide yields the target product, 5-animo-2,3-dihydrophthalazine-1,4-dione sodium salt. The method allows to produce the medicinal preparation with high pharmaceutical activity. It is provided an example of application of this preparation. |
