- DSP-4 hydrochloride (N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine hydrochloride) is a selective neurotoxin targeting noradrenergic neurons, acting via the norepinephrine transporter (NET) to induce neuronal damage[1,2]

尽管如此,DSP-4 盐酸盐(腹腔注射;50 mg/kg;单剂量)会破坏 LC 纤维和神经元 [1]。
- 损伤成年大鼠蓝斑核(LC)-下丘(IC)去甲肾上腺素能投射:成年Sprague-Dawley大鼠单次腹腔注射DSP-4盐酸盐(50 mg/kg)。处理后7天,免疫组化染色显示IC区酪氨酸羟化酶(TH,去甲肾上腺素能神经元标志物)阳性纤维减少75%;高效液相色谱(HPLC)分析显示,IC区去甲肾上腺素(NE)含量较溶媒对照组(注射生理盐水)降低80%[1] - 对成年和发育中大鼠的神经毒性:成年Wistar大鼠腹腔注射DSP-4盐酸盐(25–50 mg/kg),去甲肾上腺素能投射区(如大脑皮层、海马、IC)NE含量呈剂量依赖性降低。50 mg/kg剂量在处理后14天使皮层NE减少70%、海马NE减少65%。发育中大鼠(1–7日龄)对毒素更敏感,低剂量(10 mg/kg,腹腔注射)即可诱导显著NE耗竭(脑干NE减少55%)和TH阳性神经元丢失,敏感性高于成年大鼠[2] - 对去甲肾上腺素能神经元的选择性:DSP-4盐酸盐(成年大鼠50 mg/kg)对脑内多巴胺(DA)和5-羟色胺(5-HT)含量无显著影响(HPLC分析),也不减少TH阳性多巴胺能神经元或色氨酸羟化酶(TPH)阳性5-羟色胺能神经元,证实其对去甲肾上腺素能神经元的选择性毒性[2] |

Animal/Disease Models: Rat[1]
Doses: 50 mg/kg Route of Administration: intraperitoneally (ip) (ip), single dose Experimental Results: Large projection neurons and optical fibers of LC were not observed. - Adult rat LC-IC projection impairment model: Adult male Sprague-Dawley rats (250–300 g) were randomly divided into 2 groups (n=6/group): 1) Vehicle control: single intraperitoneal injection of sterile saline (1 mL/kg); 2) DSP-4 hydrochloride group: single intraperitoneal injection of DSP-4 hydrochloride (50 mg/kg, dissolved in sterile saline, 1 mL/kg). Seven days after injection, rats were deeply anesthetized, transcardially perfused with 4% paraformaldehyde, and brains were harvested for immunohistochemical staining (TH antibody) and HPLC analysis of NE content in the IC[1] - Adult and developing rat neurotoxicity model: 1) Adult male Wistar rats (200–250 g): divided into 4 groups (n=5/group) receiving single intraperitoneal injections of saline, 10 mg/kg, 25 mg/kg, or 50 mg/kg DSP-4 hydrochloride. 2) Developing rats (1, 3, 7 days old): divided into 2 groups (n=5/group) receiving saline or 10 mg/kg DSP-4 hydrochloride (intraperitoneal). Rats were sacrificed 1, 7, or 14 days post-treatment; brains were dissected into regions (cortex, hippocampus, brainstem, IC), and NE, DA, and 5-HT contents were measured by HPLC[2] |
| 毒性/毒理 (Toxicokinetics/TK) |
- Selective neurotoxicity: DSP-4 hydrochloride specifically damages noradrenergic neurons without affecting dopaminergic or serotonergic neurons at therapeutic doses (10–50 mg/kg, intraperitoneal)[2]
- Age-dependent toxicity: Developing rats (neonatal to 1-week-old) are 3–5 times more sensitive to DSP-4 hydrochloride than adult rats; a 10 mg/kg dose induces significant NE depletion in neonates, while adult rats require ≥25 mg/kg for similar effects[2] - Systemic toxicity: Adult rats treated with DSP-4 hydrochloride (up to 50 mg/kg, intraperitoneal) showed no obvious systemic toxicity (e.g., weight loss <5%, no lethargy or organ damage) during the 14-day observation period[1,2] |

- DSP-4 hydrochloride is a widely used research tool to study the function of the central noradrenergic system, particularly LC-derived projections, by selectively ablating noradrenergic neurons[1,2] - Its neurotoxic mechanism is thought to involve uptake into noradrenergic neurons via the NET, followed by the formation of cytotoxic metabolites that induce oxidative stress and neuronal apoptosis[2] |

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
工作液浓度: mg/mL;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。
