Nitrile analogs of meperidine as high affinity and selective sigma-1 receptor ligands
摘要:
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 sigma ligands prompted analysis at a receptors to determine the SAR for affinity at sigma receptors. Within the N-substituent series the saturated analogs showed increased affinity at both a receptors. Optimal chain length in the N-arylalkyl series for sigma(1) and sigma(2) 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 sigma(1) affinity; no change in affinity at sigma(2) was shown. The N-isobutyl, N-phenylpropyl, and N-benzyl analogs are worth pursuing due to their good affinity and selectivity at the sigma(1) receptor, whereas the N-benzyl analog exhibits the greatest selectivity for sigma(1).

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
