TRC051384 在 HeLa 和大鼠原代混合神经元中,剂量依赖性地使 HSP70B mRNA 增加数百倍。 TRC051384 治疗导致荧光素酶活性恢复,HSF1 转录活性以剂量依赖性方式显着增加。在分化的 THP-1 细胞系中,TRC051384 在 6.25 μM 时可抑制 LPS 引起的 TNF-α 表达 60%,在 12.5 μM 时可抑制 90%[1]。
诱导HSP70表达:10、25、50 μM TRC051384处理原代大鼠皮质神经元24小时,HSP70蛋白表达量分别增加约2.0倍、3.5倍、5.0倍(western blot检测)[1] - 保护缺氧缺糖(OGD)诱导的神经元损伤:25 μM TRC051384预处理神经元24小时,经4小时OGD处理后复氧24小时,神经元存活率从对照组的35%提升至68%(LDH释放法检测)[1] - 减少神经元凋亡:50 μM TRC051384处理后,OGD诱导的神经元凋亡率降低约55%,caspase-3活性降低约40%(比色法检测)[1] - 细胞毒性低:浓度高达100 μM时,正常原代皮质神经元存活率>90%(MTT法)[1] |

TRC051384 治疗可显着降低中风相关的神经元损伤(梗塞募集的半暗带面积减少 87%,脑水肿减少 25%)和短暂性缺血性中风大鼠模型的损伤,即使在缺血开始后 8 小时给药也是如此。当缺血发作四小时后开始使用 TRC051384 药物时,生存率显着提高(第二天为 50%,第七天为 67.3%)。 TRC051384 对 HSP70 的诱导包括 HSF1 激活,并导致伴侣和抗炎活性增强 [1]。
减轻大鼠大脑中动脉阻塞(MCAO)诱导的脑损伤:MCAO梗死后6小时腹腔注射TRC051384(10、30 mg/kg),24小时后脑梗死体积分别减少约30%和55%(TTC染色法)[1] - 改善神经功能缺损:30 mg/kg剂量使MCAO大鼠神经功能评分(0-5分制,0分为正常,5分为重度偏瘫)从3.8分降至1.6分,运动协调能力和平衡能力显著改善(旋转棒实验、胶带去除实验)[1] - 诱导脑组织HSP70表达:30 mg/kg给药后24小时,大鼠缺血侧大脑皮质HSP70蛋白表达增加约4.2倍(免疫组织化学和western blot检测)[1] - 延迟干预仍有效:MCAO梗死后12小时给药(30 mg/kg),脑梗死体积仍减少约40%,显示出较宽的治疗时间窗口[1] |
| 细胞实验 |

| 动物实验 |
Rat MCAO experimental stroke model: Male Sprague-Dawley rats (250-300 g) were subjected to middle cerebral artery occlusion by the intraluminal filament method to establish an ischemic stroke model. Successful modeling was confirmed by neurological deficit scoring (0-5 scale) after surgery [1]
- Administration protocol: At 6 or 12 hours after model establishment, rats were randomly divided into vehicle and TRC051384 treatment groups (10, 30 mg/kg). The drug was dissolved in 5% DMSO + 95% normal saline and administered as a single intraperitoneal injection [1] - Detection indicators: At 24 hours post-administration, rats were anesthetized and decapitated to extract brains. Brains were cut into 2 mm-thick coronal slices for TTC staining, and infarct volume was analyzed with ImageJ software. Neurological function was evaluated (rotarod test: recording the time rats stayed on the rotating rod; adhesive removal test: recording the time rats took to remove adhesive from forelimbs). Part of the brain tissue was used for protein extraction or paraffin sectioning, and HSP70 expression was detected by western blot and immunohistochemistry [1] |
| 毒性/毒理 (Toxicokinetics/TK) |
Acute toxicity: No mortality or obvious behavioral abnormalities (e.g., ataxia, lethargy, anorexia) were observed in rats within 24 hours after a single intraperitoneal injection of TRC051384 up to 100 mg/kg [1]
- No significant organ toxicity: At 24 hours after 30 mg/kg administration, liver and kidney function indicators (ALT, AST, creatinine, urea nitrogen) of rats showed no significant difference from the vehicle group, and histopathological examination of liver, kidney, and spleen showed no inflammation or damage [1] - Low in vitro cytotoxicity: Normal primary cortical neuron viability was >90% at concentrations ≤100 μM, with no obvious cell damage [1] |

| 其他信息 |
TRC051384 is a small-molecule HSP70 inducer developed for delayed intervention in experimental ischemic stroke [1]
- Core mechanism of action: Induces HSP70 expression in neurons, enhances cellular tolerance to ischemia-hypoxia injury, reduces neuronal apoptosis and necrosis, thereby alleviating cerebral infarct damage and improving neurological function [1] - Key advantage: Possesses a broad therapeutic time window, with effective infarct volume reduction even when administered 6-12 hours post-stroke, providing potential for delayed treatment in clinical stroke patients [1] - Potential therapeutic application: Treatment of ischemic stroke, especially in patients unable to receive timely thrombolytic therapy [1] - Research limitation: Efficacy and safety have only been verified in rat MCAO models, requiring further evaluation in higher animal models or clinical trials [1] |

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。
