  Synthesis, Pharmacological Evaluation, and σ₁ Receptor Interaction Analysis of Hydroxyethyl Substituted Piperazines

  摘要：

  Starting from (S)- or (R)-aspartate, three synthetic strategies were explored to prepare hydroxyethyl substituted piperazines with different substituents at the N-atoms. sigma receptor affinity was recorded using receptor material from both animal and human origin, sigma(1) affinities determined with guinea pig brain and human RPMI 8226 tumor cell lines differed slightly but showed the same tendency. (S)-2-[4-(Cyclohexylmethyl)-1-(naphthalene-2-ylmethyl)piperazin-2-yliethanol (7c) revealed the highest affinity at human sigma(1) receptors (K-i = 6.8 nM). The potent a, receptor ligand 7c was able to inhibit selectively the growth of three human tumor cell lines with IC50 values in the low micromolar range. The reduced growth of the RPMI-8226 cell line was caused by apoptosis. The interaction of 7c with the a, receptor was analyzed in detail using the 3D homology model of the sigma(1) receptor. The calculated free binding energies of all hydroxyethylpiperazines nicely correlate with their recorded affinities toward the human a, receptor.
