Abstract

Several lines of evidence suggest that selective sigma-2 (σ) ligands might be useful for the treatment of solid tumors. However, very few selective σ ligands have been identified. This study was aimed at identifying new selective σ receptor ligands using a previously identified agent, SYA 013 as a lead. Four groups, homopiperazine, piperazine, tropane and selected oxime analogs of the homopiperazines were identified, synthesized and subsequently screened at the σ and σ receptors. The results demonstrate that these scaffolds can be modified to obtain selective σ receptor ligands. 1-(5-Chloropyridin-2-yl)-4-(3-((4-fluorophenyl)thio)propyl)-1,4-diazepane, 7 and 3-(4-chlorophenyl)-8-(3-((2-fluorophenyl)thio)propyl)-8-azabicyclo[3.2.1]octan-3-ol, 21 were identified as the highest binding affinity ligands (σKi = 2.2 nM) and (4-(4-(5-chloropyridin-2-yl)-1,4-diazepan-1-yl)-1-(4-fluorophenyl)-butan-1-one oxime, 22 as a high affinity and the most selective ligand for the σ receptor (σKi/σKi = 41.8).

摘要

有几条证据表明,选择性西格玛-2(σ)配体可能对治疗实体瘤有用。然而,已经鉴定出的选择性σ配体非常少。本研究旨在使用先前鉴定的一种试剂 SYA 013 作为先导化合物,鉴定新的选择性σ受体配体。鉴定、合成了 4 组同哌嗪、哌嗪、托烷和同哌嗪的选定肟类似物,并随后在 σ 和 σ 受体上进行了筛选。结果表明,这些支架可以进行修饰以获得选择性σ受体配体。1-(5-氯吡啶-2-基)-4-(3-((4-氟苯基)硫基)丙基)-1,4-二氮杂环庚烷,7 和 3-(4-氯苯基)-8-(3-((2-氟苯基)硫基)丙基)-8-氮杂双环[3.2.1]辛烷-3-醇,21 被鉴定为具有最高结合亲和力的配体(σKi = 2.2 nM)和(4-(4-(5-氯吡啶-2-基)-1,4-二氮杂环庚烷-1-基)-1-(4-氟苯基)-丁-1-酮肟,22 作为高亲和力和最选择性的 σ 受体配体(σKi / σKi = 41.8)。
