Amantadine organic acid ion salt as well as preparation method and application thereof

Abstract

The invention discloses amantadine organic acid ionic salt as well as a preparation method and the application thereof. The ionic salt comprises anions and cations. The precursors of the anions are organic acids, and precursors of the cations are amantadine. The amantadine organic acid ionic salt provided by the embodiment of the invention not only has pharmacological properties (antiviral and bacteriostatic properties and the like) of amantadine and an organic acid precursor, but also has good water solubility; and damage to organs caused by poor water solubility of adamantane in the oral administration process is avoided.

Description

technical field [0001] The invention relates to the technical field of drug synthesis, in particular to an amantadine organic acid ion salt and a preparation method and application thereof. Background technique [0002] Viruses are non-cellular parasitic living organisms composed of nucleic acid molecules and proteins. Due to the strong reproductive capacity of viruses, once infection occurs, systemic poisoning symptoms such as fever, headache, and cough, as well as virus hosts and invasion will appear. Local symptoms (diarrhea, rash, liver function damage, etc.) caused by inflammatory damage to tissues and organs. Symptoms vary depending on the virus, and some viruses can also damage the myocardium, causing viral myocarditis. Therefore, antiviral drugs are usually required. [0003] Amantadine, also known as tricyclic decylamine, is a commonly used antiviral drug, which is usually prepared by reacting adamantane with urea after bromination. It was used to inhibit influen...
