PRE-084 hydrochloride is a highly selective sigma-1 receptor (S1R) agonist with an IC50 value of 44nM[1]. PRE-084 hydrochloride has demonstrated broad neuroprotective and anti-inflammatory effects across multiple models of neurodegeneration and neuroinflammation such as Parkinson’s disease and amyotrophic lateral sclerosis[3][4][5].
In vitro, PRE-084 hydrochloride (10µM) treatment on dorsal root ganglia (DRG) neurons isolated from CFA-treated rats for 30min led to a decrease in the fast sodium current, which was associated with a diminished action potential (AP) peak and maximum depolarizing rate (MDR), as well as an increased rheobase[2]. PRE-084 hydrochloride (0.1–20µM) and β-amyloid fragment 25–35 (25µM) were co-applied to rat cortical neuronal cultures for 24h. PRE-084 hydrochloride reduced neuronal toxicity in a bell shaped-manner with maximally neuroprotective effect at 10µM and blocked the β-amyloid-induced rise in the pro-apoptotic protein Bax[3]. PRE-084 hydrochloride (2.5μg/mL) applied on BV-2 cells when cells challenged with S. pneumoniae at 20 MOI for 6h exerted anti-inflammatory effect by reducing the expression of phosphorylated STAT1 (p-STAT1) and NLRP3[4].
In vivo, PRE-084 hydrochloride (0.25µg/g) was administered intraperitoneally into the wobbler (wr) mouse model of spontaneous motor-neuron degeneration three times per week from the 4th to the 12th week of age. PRE-084 hydrochloride treatment increased the number of surviving motor neurons, raised cervical spinal-cord BDNF levels, while attenuating reactive astrogliosis and shifting microglia/macrophages toward a CD68⁺ and CD206⁺ tissue-repair phenotype in wr mice[5]. PRE-084 hydrochloride (3mg/kg) administrated intraperitoneally into streptozotocin induced diabetic rats once a day for a week enhanced vasoconstrictor and platelet aggregator and reduced vasodilator and anti-aggregator cyclooxygenase product formation[6]. PRE-084 hydrochloride (1mg/kg) were administered into myocardial ischemia/reperfusion model rats 1h before operation. PRE-084 hydrochloride preserved cardiac function and reduced myocardial apoptosis through the activation of Akt and eNOS[7].

在体外实验中，PRE-084 hydrochloride（10µM）处理CFA诱导的大鼠背根神经节（DRG）神经元30min，可降低快钠电流，进而减少动作电位（AP）峰值和最大去极化速率（MDR），并提高基强度[2]。将PRE-084 hydrochloride（0.1–20µM）与β-淀粉样蛋白片段25–35（25µM）共处理大鼠皮层神经元培养物24h，PRE-084 hydrochloride以钟形剂量依赖方式降低神经元毒性，在10µM时神经保护作用最强，并阻断β-淀粉样蛋白诱导的促凋亡蛋白Bax升高[3]。当BV-2细胞以20 MOI的S.pneumoniae刺激6h时，PRE-084 hydrochloride（2.5μg/mL）通过降低磷酸化STAT1（p-STAT1）和NLRP3的表达发挥抗炎作用[4]。
在体内实验中，PRE-084 hydrochloride（0.25µg/g）于第4至第12周龄期间每周三次腹腔注射给予自发性运动神经元退化的wobbler（wr）小鼠模型。PRE-084 hydrochloride治疗增加了存活运动神经元数量，提高颈髓BDNF水平，同时减轻反应性星形胶质细胞增生，并使小胶质细胞/巨噬细胞向CD68⁺和CD206⁺组织修复表型转变[5]。PRE-084 hydrochloride（3mg/kg）每日一次腹腔注射给予链脲佐菌素诱导的糖尿病大鼠，持续一周，可增强血管收缩剂和血小板聚集剂，并减少血管舒张剂和抗聚集剂环氧化酶产物的形成[6]。PRE-084 hydrochloride（1mg/kg）于手术前1h腹腔注射给予心肌缺血/再灌注模型大鼠，PRE-084 hydrochloride通过激活Akt和eNOS保留心脏功能并减少心肌细胞凋亡[7]。
| Cell experiment [1]: | |
Cell lines | Rat dorsal root ganglion (DRG) neurons |
Preparation Method | DRG neurons were collected from six sham rats and six rats after three days of CFA injection One portion was used as control, and the other was treated with PRE-084 hydrochloride (10µM) for 30min before further processing. |
Reaction Conditions | 10μM; 30min |
Applications | Activation of Sig-1R through PRE-084 hydrochloride led to a decrease in the fast sodium current in isolated DRG neurons from CFA-treated rats, which was associated with a diminished action potential (AP) peak and maximum depolarizing rate (MDR), as well as an increased rheobase. PRE-084 hydrochloride was also observed to enhance the slow component of the sodium current, resulting in hyperpolarization of the threshold potential and an increase in AP firing frequency. |
