A potent sigma (σ) receptor ligand was isolated from the culture broth of Streptomyces longispororuber #525. The active compound was identified to be (2R-trans)-2-butyl-5-heptylpyrrolidine by spectroscopic and chemical studies. The compound exhibited high affinity and selectivity for σ receptors. The IC50 values toward σ1, σ2 and dopamine D2 receptors were 2.0, 22.7 and more than 40, 000 nM, respectively. Its (2S-trans)- and (±)-cis-isomers, both synthesized, were also found to be high affinity σ ligands.
从长孢子链霉菌(Streptomyces longispororuber #525)的培养液中分离出一种强效的σ(sigma)受体配体。通过光谱和化学研究,确定该活性化合物为 (2R-trans)-2- 丁基-5-庚基吡咯烷。该化合物对 σ 受体具有高亲和力和选择性。对 σ1、σ2 和多巴胺 D2 受体的 IC50 值分别为 2.0、22.7 和超过 40,000 nM。合成的(2S-反式)-和(±)-顺式异构体也被发现是高亲和力的σ配体。
