Herein we report the SAR study which involved structural modifications to the linker length, aryl substitution and alkylamine ring size of the benzo[d]thiazol-2(3H)one based sigma receptor (σ) ligands. Many compounds in this series displayed low nanomolar affinity for the σ receptor subtypes. In particular, 8a showed high affinity (σ-1 Ki = 4.5 nM) for σ-1 receptors and moderately high selectivity
在此,我们报告SAR研究,其中涉及基于苯并[ d ]噻唑-2( 3H )酮的σ受体(σ)配体的接头长度、芳基取代和烷基胺环大小的结构修饰。该系列中的许多化合物对 σ 受体亚型表现出低纳摩尔亲和力。特别是, 8a对 σ-1 受体表现出高亲和力(σ-1 K i = 4.5 nM),并对 σ-2 受体表现出中等高的选择性(483 倍)。
