Duraglutin artificial antigen and preparation method thereof

Paragraph 0032-000033, (2020/07/28)
The invention provides a duramine artificial antigen and a preparation method thereof. The nitrile group of the 4-phenylpiperidine-4-carbonitrile is ingeniously reduced into the amino group; carboxylgroups capable of being used for crosslinking are introduced, so the characteristic original appearance of a duraglutin main ring is maintained; butanedioic anhydride is introduced, so acetyl functional groups on a duraglutin side chain is maintained on the said chain; the hapten synthesized by the process can maintain the characteristic group original appearance of duraglutin, and the synthesizedcorresponding artificial antigen has good specificity. The preparation process is simple, and the raw material source is not limited; the prepared artificial antigen can be used for animal immunization to obtain a corresponding duraglutin antibody, has strong antibody specificity, can be used in immunoassay, is suitable for research of various duraglutin immunoassay methods, and can be used as akey raw material for production of a duraglutin immunochromatographic kit.

Nitrile analogs of meperidine as high affinity and selective sigma-1 receptor ligands

A series of N-substituted-4-cyano-4-phenylpiperidine analogs were synthesized and evaluated for binding affinity at opioid receptors and showed no affinity. The series similarity to previously reported σ ligands prompted analysis at σ receptors to determine the SAR for affinity at σ receptors. Within the N-substituent series the saturated analogs showed increased affinity at both σ receptors. Optimal chain length in the N-arylalkyl series for σ1 and σ2 receptors proved to be N-propylphenyl; extension to a four carbon chain dramatically decreased affinity at both receptors. Substituents in the 4-position affect only σ1 affinity; no change in affinity at σ2 was shown. The N-isobutyl, N-phenylpropyl, and N-benzyl analogs are worth pursuing due to their good affinity and selectivity at the σ1 receptor, whereas the N-benzyl analog exhibits the greatest selectivity for σ1.
