Cutamesine (SA4503) is a potent and selective agonist for the sigma 1 receptor subtype in the brain. Cutamesine (SA4503) inhibited specific (+)-[3H]pentazocine binding in a competitive manner(IC50 = 17.4 +/- 1.9 nM) in guinea pig meninges[1，4].
Cutamesine (SA4503) prevents cultured cortical neurons from cell death caused by H2O2 application. The survival effect by Cutamesine (SA4503) reached a plateau at 0.1 μM[3]. Cutamesine(SA4503) reduces the activation of the MAPK/ERK pathway and down-regulated the ionotropic glutamate receptor, GluR1[2]. Cutamesine(SA4503) protects motor neuron NSC34 cells against superoxide dismutase 1 and serum free neurotoxicity. It upregulates the phosphorylation levels of Akt and extracellular signal-regulated kinase (ERK) 1/2 [2].
Cutamesine (SA4503) extended the survival time, but it did not delay the disease onset in the SOD1G93A mice. The extended survival time in the Cutamesine (SA4503) group may be associated with the suppression of the progression of motor neuron damage by the upregulation of phosphorylated Akt and ERK1/2. From these results, Cutamesine (SA4503) may have the protective effect against FALS, because SOD1G93A mice are model of FALS [2]. When examined the effects of Cutamesine (SA4503) on the cholinergic dysfunction-induced memory impairments in a passive avoidance task. Single administration of Cutamesine (SA4503) significantly reduced the scopolamine-induced memory impairment [5]. Cutamesine (SA4503) produced a significant decrease and rise in the number of spontaneously active SNC and VTA DA neurons in rats. Cutamesine (SA4503) produced a significant increase in the number of spontaneously active VTA DA neurons relative to SNC DA neurons Repeated administration of Cutamesine (SA4503) produced a greater change in the firing pattern of spontaneously active VTA[6]. Repeated treatment with Cutamesine (SA4503) (0.3 mg/kg) improved the behavior disorder similar to depressive symptoms in rats in olfactory bulb resection group. Cutamesine (SA4503) also reversed the reduction of NMDA receptor subunit (NR)1 protein expression in the prefrontal cortex, hippocampus, and amygdala of olfactory bulbectomy rats, but did not affect NR2A or NR2B[7].

Cutamesine (SA4503) 是大脑中 sigma 1 受体亚型的有效选择性激动剂。 Cutamesine (SA4503) 在豚鼠脑膜中以竞争性方式抑制特异性 (+)-[3H]pentazocine 结合 (IC50 = 17.4 +/- 1.9 nM)[1，4]< /sup>.
Cutamesine (SA4503) 可防止培养的皮层神经元因 H2O2 应用而导致细胞死亡。 Cutamesine (SA4503) 的存活效应在 0.1 μM[3] 时达到稳定水平。 Cutamesine(SA4503) 可降低 MAPK/ERK 通路的激活并下调离子型谷氨酸受体 GluR1[2]。 Cutamesine (SA4503) 保护运动神经元 NSC34 细胞免受超氧化物歧化酶 1 和无血清神经毒性。它上调Akt和细胞外信号调节激酶（ERK）1/2的磷酸化水平[2]。
Cutamesine (SA4503) 延长了 SOD1G93A 小鼠的存活时间，但并未延迟疾病发作。 Cutamesine (SA4503) 组的延长生存时间可能与通过上调磷酸化 Akt 和 ERK1/2 抑制运动神经元损伤的进展有关。从这些结果来看，Cutamesine (SA4503) 可能对 FALS 具有保护作用，因为 SOD1G93A 小鼠是 FALS 的模型[2]。当检查 Cutamesine (SA4503) 对被动回避任务中胆碱能功能障碍引起的记忆障碍的影响时。单次服用 Cutamesine (SA4503) 可显着降低东莨菪碱诱导的记忆障碍[5]。 Cutamesine (SA4503) 使大鼠自发活跃的 SNC 和 VTA DA 神经元数量显着减少和增加。相对于 SNC DA 神经元，Cutamesine (SA4503) 显着增加了自发活跃的 VTA DA 神经元的数量重复给予 Cutamesine (SA4503) 在自发活跃的 VTA 放电模式中产生了更大的变化[6]。 Cutamesine (SA4503) (0.3 mg/kg)重复治疗改善了嗅球切除组大鼠类似抑郁症状的行为障碍。 Cutamesine (SA4503) 还可以逆转嗅球切除术大鼠前额皮质、海马和杏仁核中 NMDA 受体亚基 (NR)1 蛋白表达的减少，但不影响 NR2A 或 NR2B[7]。
