Understanding the structural requirements of 4-anilidopiperidine analogues for biological activities at μ and δ opioid receptors
摘要:
New 4-anilidopiperidine analogues in which the phenethyl group of fentanyl was replaced by several aromatic ring-contained amino acids (or acids) were synthesized to study the biological effect of the substituents on mu and delta opioid receptor interactions. These analogues showed broad (47 nM-76 mu M) but selective (up to 17-fold) binding affinities at the V opioid receptor over the 6 opioid receptor, as predicted from the message-address concept.

The present invention is directed to a method for preparing a 4-alkoxyalkyl-4-phenylaminopiperidine compound which comprises the steps of (a) reacting an N-substituted-4-piperidone compound with an aniline compound to form a Schiff base compound, (b) reacting the Schiff base compound with an anionic reagent having an anion stabilizing group to form an amine compound, and (c) reducing the amine compound in step (b) with a reducing agent to displace the anion stabilizing group. The anionic reagent in step (b) above has the general formula: X--CYM--Z wherein X is an anion stabilizing group, Y is hydrogen or lower-alkyl, Z is lower-alkoxy or phenylmethoxy, M is an alkali or alkaline earth metal, and C is a carbon atom.

In vitro radical-cation scavenging capacity and anti-AChE activities of 19 piperidine derivatives, including dihydrospiro[ piperidine-4,2(1H)quinolines] 7-19 and their precursor 4-allyl-4-arylaminopiperidines 1-6 were reported. Their data of bioassays and calculated logP and TPSA parameters showed promising drug-like properties. The best radical scavenging compound (TEAC 1.73 ± 0.01), 6-methyl-3,4- dihydrospiro[piperidine-4,2(1H)quinoline] 8 showed IC50 value of 62.5 μM (20.0 μg/mL) using AChE assay.

A simple and convenient synthetic approach to the new series of 1,2,3,4,5,6,7,8-octahydro-1,6-naphthyridines 1a-j has been developed. This was achieved via a one-pot process combining metalated 4-piperidinonimine alkylation and intramolecular cyclization.
