Abstract

The invention discloses an amantadine artificial hapten and an artificial antigen as well as a preparation method and application of the amantadine artificial hapten and the artificial antigen. The molecular structural formula of the amantadine artificial hapten is as shown in the formula (I), and the molecular structural formula of the amantadine artificial antigen is as shown in the formula (II). The application is to utilize the amantadine artificial antigen to prepare an amantadine antibody. The amantadine artificial hapten disclosed by the invention retains the feature structure of amantadine to the largest extent, comprises active groups capable of being linked and coupled with carrier protein as an antigen determinant; the prepared and obtained amantadine artificial antigen can be immunized to obtain the amantadine antibody with high affinity, high sensitivity and high specificity; the titer of immune serum obtained by immunizing a New Zealand white rabbit is up to 1:70000; the amantadine artificial hapten and the artificial antigen can be used for quick and accurate immunodetection and immunoassay to amantadine.

Description

technical field [0001] The invention belongs to the technical field of biochemical industry, and in particular relates to an amantadine artificial hapten, artificial antigen and a preparation method and application thereof. Background technique [0002] Amantadine can inhibit the virus from penetrating into the host cell, affect the uncoating of the virus, and inhibit its reproduction. It is clinically used to prevent and treat human influenza virus infection. It has the characteristics of low price and obvious drug effect. Drugs for the treatment of Parkinson's disease. However, the accumulation of amantadine can cause various adverse reactions such as drowsiness, insomnia, dizziness, depression, nausea, and loss of appetite to the human body, and has certain toxic and side effects. Long-term use of amantadine can also cause the virus to develop drug resistance to varying degrees and induce new drug-resistant viruses. [0003] However, in November 2012, the media revealed...
