Conservative chemical modifications of the core structure of the lead spipethiane (1) afforded novel potent σ1 ligands. σ1 affinity and σ1/σ2 selectivity proved to be favored by the introduction of polar functions (oxygen atom or carbonyl group) in position 3 or 4 (4−6) or by the elongation of the distance between the two hydrophobic portions of the molecule with the simultaneous presence of a carbonyl
引线spipethiane的核心结构的保守性的化学修饰(1),得到新的有效σ 1个配体。σ 1亲和力和σ 1 / σ 2选择性证明通过在位置3或4(引入极性官能团(氧原子或羰基)受到青睐4 - 6)或通过的距离的两个疏水性部分之间的伸长在位置4(8和9)上同时存在羰基的分子。针对人乳腺癌细胞系MCF-7所观察到的细胞抑制效应/ ADR,高度表达σ 1受体,而不是针对MCF-7,以及吗啡镇痛的增强强调σ 1这一系列化合物的拮抗剂轮廓。特别是,由于其高σ 1和亲和力(P ķ我= 10.28)和σ 1 /σ 2选择性比率(29510),化合物9可能是σ受体表征新颖有价值的工具和用于合理设计一个合适的模板潜在治疗上有用的σ 1拮抗剂。
