Clopyralid
Based on 1 publication(s) in Google Scholar
Clopyralid is a selective pyridine carboxylic acid auxin-type herbicide that mimics plant auxins to trigger abnormal growth and subsequent death of target plants. Clopyralid is a nitrite reductase inhibitor that impairs nitrite reduction and reduces NADH. Clopyralid entering aquatic environments interferes with microbial denitrification, induces oxidative damage and nitrite accumulation, and alters microbial community diversity and composition. Clopyralid can be used for related research on farmland control.

Biological Activity
Description
In Vitro
Clopyralid (0.25-60 mg/L; stages II-VII) inhibits NIR but not NAR in denitrifying activated sludge, inhibiting carbon metabolism and electron transfer[1].
Clopyralid causes the denitrifying sludge community diversity to exhibit a U-shaped change pattern and enriches specific taxa such as Thauera, Acinetobacter, and Shinella at higher exposure levels[1].
Clopyralid is a selective pyridine carboxylic acid auxin-type herbicide that mimics plant auxins to trigger abnormal growth and subsequent death of target plants; it also undergoes rapid dissipation in subtropical loam following first-order kinetics, with a half-life of 13.39 days[2].

Solvent & Solubility
In Vitro:
DMSO : 100 mg/mL (520.83 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (13.02 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (13.02 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
