Synthesis and Biological Evaluation of Novel Sigma-1 Receptor Antagonists Based on Pyrimidine Scaffold As Agents for Treating Neuropathic Pain
摘要:
The discovery and synthesis of a new series of pyrimidines as potent sigma-1 receptor (sigma R-1) antagonists, associated with pharmacological antineuropathic pain activity, are the focus of this article. The new compounds were evaluated in vitro in sigma-1 and sigma-2 receptor binding assays. The nature of the pyrimidine scaffold was crucial for activity, and a basic amine was shown to be necessary according to the known pharmacophoric model. The most promising derivative was 5-chloro-2-(4-chlorophenyl)-4-methyl-6-(3-(piperidin-1-yl)propoxy)pyrimidine (137), which exhibited a high binding affinity to sigma R-1 receptor (K-i sigma(1) = 1.06 nM) and good sigma-1/2 selectivity (1344-fold). In in vivo tests, compound 137 exerted dose-dependent antinociceptive effects in mice formalin model and rats CCI models of neuropathic pain. In addition, no motor impairments were found in rotarod tests; acceptable pharmacokinetic properties were also noted. These data suggest compound 137 may constitute a novel class of drugs for the treatment of neuropathic pain.
