Parkinson's disease (PD) is a neurodegenerative disorder characterized by the progressive degeneration of dopaminergic neurons in the substantia nigra. Current clinical treatments for PD remain limited, highlighting the urgent need for innovative drug development. In this study, we synthesized a protonic bis-pyridazine (H-Py) compound using an intermolecular proton transfer technique. In MPP+-induced PD model cells, H-Py significantly improved cell viability and reduced ROS levels. In 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP)-induced PD model mice, H-Py demonstrated good safety and ameliorated motor dysfunction, with efficacy showing no significant difference from that of levodopa, a first-line PD therapeutic agent. Furthermore, immunofluorescence analysis of tyrosine hydroxylase (TH) levels in the substantia nigra and striatum revealed that H-Py administration significantly increased TH expression in these brain regions. Western blot analysis suggested that H-Py may protect against neuronal damage by activating the Nrf2/HO-1 pathway and alleviating oxidative stress. The experimental protocol was approved by the Animal Experiment Ethics Committee of Southwest University (approval No.: IACUC-20250714-05). In summary, this study may provide new strategies and insights for PD treatment.

帕金森病(Parkinson's disease, PD) 属于神经系统退行性疾病, 其核心病理特征表现为黑质中的多巴胺能神经元发生进行性退变。目前临床上针对PD的治疗药物仍然有限, 亟须加强创新药物的研发。本研究通过分子间质子转移技术, 合成了质子型双哒嗪(protonic bis-pyridazine, H-Py); 在1-甲基-4-苯基吡啶离子(1-methyl-4-phenylpyridinium ion, MPP+) 诱导的PD模型细胞中, H-Py可明显改善细胞活力并降低活性氧水平; 在1-甲基-4-苯基-1,2,3,6-四氢吡啶(1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine, MPTP) 诱导的PD模型小鼠体内, H-Py具有良好安全性, 并且能够改善模型小鼠的运动功能障碍, 其效果与PD的一线治疗药物左旋多巴无显著性差异。此外, 本研究还通过免疫荧光法分析了脑部黑质、纹状体中酪氨酸羟化酶(tyrosine hydroxylase, TH) 的含量, 结果显示, H-Py给药显著提升了小鼠黑质和纹状体内的TH表达水平。通过Western blot检测, H-Py可能通过激活核因子红系相关因子2 (nuclear factor erythroid 2-related factor 2, Nrf2) 和血红素加氧酶-1 (heme oxygenase-1, HO-1) 来减轻氧化损伤, 从而保护神经元。实验方案由西南大学动物实验伦理委员会批准(批准号: IACUC-20250714-05), 严格按照动物使用和护理的伦理原则进行实验操作。总之, 本研究可能为PD的治疗研究提供新的方法和思路。
