Paraquat (dichloride) is a non-selective herbicide widely used in agriculture [1]. Paraquat (dichloride) destroys plant cell structures by inducing reactive oxygen species during photosynthesis [2]. Paraquat (dichloride) is highly toxic to humans and animals and can cause fatal pulmonary fibrosis [3].
In BV-2 microglial cells, Paraquat (dichloride) (50μM; 24h) induced morphological changes, ROS production, and cytotoxicity in BV-2 microglial cells [4]. In cerebellar granule cells, exposure to relatively low concentrations of Paraquat (dichloride) (5μM; 24h) resulted in apoptotic cell death, decreased mitochondrial cytochrome c content, increased proteolytic activation and caspase-3 activity, and DNA fragmentation [5]. In pulmonary microvascular endothelial cells, Paraquat (dichloride) (0.1mM, 0.5mM, 2mM; 72h) caused a time-dependent increase in lactate dehydrogenase release [6]. In in cortical cells, exposed to Paraquat (dichloride) (10μM; 72h) often had shrunken cell bodies with condensed nuclei and sparse or collapsed dendrites [7].
In kunming mice, Paraquat (dichloride) (0.89mg/kg, 2.67mg/kg, 8mg/kg; po; 28d) has toxic effects on mouse hippocampal tissue, and its toxic mechanism may be related to mitochondrial damage of hippocampal neurons caused by oxidative stress [8]. In swiss-webster mice, Paraquat (dichloride) (30 mg/kg; ip; single injection) reduces the concentrations of water-soluble antioxidants and reduced glutathione in the liver and lipid-soluble antioxidants in the lung [9]. In C57BL/6 mice, long-term repeated oral administration of Paraquat (dichloride) (10mg/kg; ig; 4 months) can selectively impair the nigrostriatal dopaminergic system of mice [10].

| Cell experiment [1]: | |
|
Cell lines |
BV-2 microglial cells |
|
Preparation Method |
The MTT assay was used for assessment of cell viability. Before treatment with Paraquat (dichloride) and inhibitors, cells were placed in serum-free DMEM. Cells were incubated with Paraquat (dichloride) and other agents for different periods up to 48 hours. After various treatments, culture medium was removed and 1mg/mL MTT dissolved in DMEM was added to the cells and incubated for 2 hours. |

Reaction Conditions |

Applications |
Paraquat (dichloride) induced morphological changes, ROS production, and cytotoxicity in BV-2 microglial cells. |
| Animal experiment [2]: | |
|
Animal models |
Kunming mice |
|
Preparation Method |
Kunming mice (aged 7 weeks, 20-23g) were used in this study. The mice were adapted to their surroundings for 1 week before the experiment was initiated. Animals were housed in a room that was maintained at a constant temperature (18-22℃) and humidity (40-50%). Animals were assigned to four groups randomly: a control group (0mg/kg) and three paraquat treatment groups with each group comprising 20 mice. The doses and time regimen were designed based on the previous researches and the LD50 (110-150mg/kg in rats) of Paraquat (dichloride). The doses of Paraquat (dichloride) were 0.89mg/kg, 2.67mg/kg, 8mg/kg body weight, respectively. Paraquat (dichloride) was administered orally in doses of 0.1mL/10g body weight, respectively, once a day and for 28 consecutive days. |

Dosage form |
0.89mg/kg, 2.67mg/kg, 8mg/kg; po; 28d |
