PKR-IN-C16 (Compound C16) 是一种特异的双链 RNA 依赖蛋白激酶 (PKR) 抑制剂。PKR-IN-C16 具有良好的神经保护作用,可挽救急性脑损伤。
生物活性 | PKR-IN-C16 (Compound C16) is a specificdouble-stranded RNA-dependent protein kinase(PKR) inhibitor. PKR-IN-C16 shows promising neuroprotective properties and can rescue acute brain lesions[1]. |
IC50& Target | |
体外研究 (In Vitro) | PKR-IN-C16 (Compound C16) is able to unlock the translation blockade induced by PKR in primary neuronal cultures[1]. PKR-IN-C16 (0.1 or 0.3 μM; 24 h) shows protective effect against the neuronal cell death induced by endoplasmic reticulum stress in SH-SY5Y cells[1]. PKR-IN-C16 (1-1000 nM; 4 h) prevents not only PKR-phosphorylation but also the activation of caspase-3 induced by Amyloid β in SH-SY5Y cells[2].
Western Blot Analysis[2] Cell Line: | Human SH-SY5Y cells | Concentration: | 1, 10, 20, 200, 1000 nM | Incubation Time: | 4 h | Result: | Markedly reduces the level of phosphorylated PKR in the cells exposed to 20 μM Amyloid β. |

体内研究 (In Vivo) | PKR-IN-C16 (Compound C16) (60 or 600 μg/kg; i.p.; 3 times) prevents not only the PKR-induced neuronal loss but also the inflammatory response in theQuinolinic acid(QA) (HY-100807) induced acute excitotoxic rat model[1]
Animal Model: | Normotensive male Wistar rats, excitotoxic neuroinflammatory model, inflammation was induced by unilateral striatal injection of quinolinic acid (QA)[1] | Dosage: | 60 or 600 μg/kg | Administration: | Intraperitoneal injection; 24 h, 2 h before QA injection and 24 h post-QA injection | Result: | Reduced expression of the active catalytic domain of the PKR, prevented increase
of IL-1β levels on the contralateral side (97% inhibition) at 600 μg/kg. Decreased by 47% the neuronal loss and by 37% the number of positive cleaved caspase-3 neurons induced by QA injection at 600 μg/kg. |
