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.
Muscarinic acetylcholine receptor binding affinities of pethidine analogs
Lee, Na-Ra,Zhang, Xuan,Darna, Mahesh,Dwoskin, Linda P.,Zheng, Guangrong
, p. 5032 - 5035 (2015/11/09)
A series of pethidine analogs were synthesized and their affinities for the [3H]N-methyl-scopolamine (NMS) binding site on muscarinic acetylcholine receptors (mAChRs) were determined using M1, M3 or M5 human mAChRs expressed by Chinese hamster ovary (CHO) cell membranes. Compound 6b showed the highest binding affinities at M1, M3 and M5 mAChRs (Ki = 0.67, 0.37, and 0.38 μM, respectively).

Nitrile analogs of meperidine as high affinity and selective sigma-1 receptor ligands
Mercer, Susan L.,Shaikh, Jamaluddin,Traynor, John R.,Matsumoto, Rae R.,Coop, Andrew
, p. 1304 - 1308 (2008/09/21)
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.
Opioids and efflux transporters. Part 3: P-glycoprotein substrate activity of 3-hydroxyl addition to meperidine analogs
Mercer, Susan L.,Cunningham, Christopher W.,Eddington, Natalie D.,Coop, Andrew
body text, p. 3638 - 3640 (2009/04/11)
Numerous studies have shown that many clinically employed opioid analgesics are substrates for P-glycoprotein (P-gp), suggesting that up-regulation of P-gp may contribute to the development of central tolerance to opioids. The studies herein focus on the development of SAR for P-gp substrate activity in the meperidine series of opioids. Addition of a 3-OH to meperidine and the ketone analog of meperidine yielding bemidone and ketobemidone, respectively, significantly increased P-gp substrate affinity. The results of this study have implications in the development of novel analgesics to be utilized as tools to study the contribution of P-gp on the development of central tolerance to opioids.
Opioids and efflux transporters. Part 1: P-Glycoprotein substrate activity of N-substituted analogs of meperidine
Mercer, Susan L.,Hassan, Hazem E.,Cunningham, Christopher W.,Eddington, Natalie D.,Coop, Andrew
, p. 1160 - 1162 (2007/10/03)
P-Glycoprotein (P-gp) is an efflux transporter which is up-regulated at the blood-brain barrier in both morphine- and oxycodone-tolerant rats. Numerous studies have shown that many clinically employed opioid analgesics are substrates for P-gp, suggesting that up-regulation of P-gp may contribute to the development of central tolerance to opioids. The studies herein focus on the development of SAR for P-gp substrate activity in the meperidine series of compounds, and show that a meperidine analog of greater potency, N-phenylbutyl-N-normeperidine, has low activity as a P-gp substrate and has the potential to be utilized as a tool to study the contribution of P-gp to the development of central tolerance to opioids.
