Oxidopamine (6-OHDA) hydrobromide 是神经递质多巴胺 (neurotransmitter dopamine) 的拮抗剂。Oxidopamine hydrobromide 是一种广泛应用的神经毒素，可选择性破坏多巴胺能神经元。Oxidopamine hydrobromide 促进COX-2激活，导致PGE2合成和促炎细胞因子IL-1β的分泌。Oxidopamine hydrobromide 可用于帕金森病 (PD)、注意缺陷多动障碍 (ADHD) 和莱施奈恩综合症的研究。
| 生物活性 | Oxidopamine (6-OHDA) hydrobromide is an antagonist of theneurotransmitter dopamine. Oxidopamine hydrobromide is a widely used neurotoxin and selectively destroys dopaminergic neurons. Oxidopamine hydrobromide promotesCOX-2activation, leading toPGE2synthesis and pro-inflammatory cytokineIL-1βsecretion. Oxidopamine hydrobromide can be used for the research of Parkinson’s disease (PD), attention-deficit hyperactivity disorder (ADHD), and Lesch-Nyhan syndrome[1][2][3][4]. |

体外研究
(In Vitro) | Oxidopamine hydrobromide (0-500 μM, 24 h) decreases the viability of both Neuro-2a cells and SH-SY5Y cells in a concentration-dependent manner[1].
Oxidopamine hydrobromide (75-150 μM, 0-24 h) induces COX-2 expression and nuclear translocation[1].
Oxidopamine hydrobromide (75-150 μM, 0-24 h) causes PGE2biosynthesis and pro-inflammatory cytokine IL-1β production[1].
Oxidopamine hydrobromide (0-150 μM, 12 h) inducesapoptosisand mitochondrial membrane depolarization of pheochromocytoma PC12 cells[3].
Oxidopamine hydrobromide (75 μM, 0-12 h) induces p38 phosphorylation[3].
Cell Viability Assay[1] | Cell Line: | Neuro-2a cells and SH-SY5Y cells | | Concentration: | 0-500 μM | | Incubation Time: | 24 or 48 h | | Result: | Induced neurotoxicity, caused cytotoxicity in both Neuro-2a cells and SH-SY5Y cells in a concentration dependent manner. EC50=111 μM for 24 h incubation and 109 μM for 48 h incubation in the Neuro-2a cells; EC50=118 μM for 24 h incubation and 107 μM for 48 h incubation in the SH-SY5Y cells. |
RT-PCR[1] | Cell Line: | Neuro-2a cells and SH-SY5Y cells | | Concentration: | 75 or 150 μM | | Incubation Time: | 0, 6 or 24 h | | Result: | Quickly and robustly induced COX-2 in a time-dependent manner. Induced COX-2 activation characterized by expression induction and nuclear translocation. Substantially increased PGE2in the culture medium by nearly 5-fold in Neuro-2a cells (at 75 μM) and 3-fold in SH-SY5Y cells (at 150 μM). Significantly upregulated the pro-inflammatory cytokine interleukin-1β (IL-1β) within Neuro-2a cells and SH-SY5Y cells. |
Apoptosis Analysis[3] | Cell Line: | PC12 cells | | Concentration: | 0, 25, 50, 75, and 150 μM | | Incubation Time: | 0, 2, 4, 6, 12, and 20 h | | Result: | Induced apoptosis of PC12 cells. Increased the activities of caspase-3, -8 and -9 in PC12 cells in a time- and concentration-dependent manner. Increased these caspase activities at 2-4 h and reached a maximum at 12 h. Decreased cells with high mitochondrial membrane potential (JC-1 aggregate) in a time- and concentration-dependent manner. |
Western Blot Analysis[3] | Cell Line: | PC12 cells | | Concentration: | 75 μM | | Incubation Time: | 0, 3, 5, 6, 8, 10, and 12 h | | Result: | Increased the level of p-p38 in a time-dependent manner. |
