Product Description
Flupyrimin is an antagonist of insect nicotinic acetylcholine receptors (nAChR).
Flupyrimin (ME5382) is an insecticidal compound primarily used to control pests in agricultural settings. It is the antagonist for insect nicotinic acetylcholine receptor (nAChR) and exhibits insecticidal effect by targeting the insect nervous system. It exhibits broad-spectrum insecticidal activity but is less toxic to pollinators (100 µg/bee) and rats (2000 mg/kg). The CAS number is 1689566-03-7, with a molecular formula of C₁₃H₉ClF₃N₃O and a molecular weight of 315.68.
Biological Activity I Assay Protocols (From Reference)
Targets
Flupyrimin targets the insect nicotinic acetylcholine receptor (nAChR). It acts as an antagonist at the insect nAChR. By blocking the nAChR, the compound disrupts neurotransmission in the insect nervous system, leading to insecticidal effects. It exhibits broad-spectrum insecticidal activity.
ln Vitro
In vitro, Flupyrimin exhibits broad-spectrum insecticidal activity. It acts as an antagonist at the insect nicotinic acetylcholine receptor (nAChR). It is less toxic to pollinators (100 µg/bee).
ln Vivo
In vivo, Flupyrimin is an insecticidal compound used to control pests in agricultural settings. It is less toxic to rats (2000 mg/kg). It is used as an insecticide.
Enzyme Assay
The in vitro receptor binding assay for Flupyrimin involves measuring its binding affinity to the insect nicotinic acetylcholine receptor (nAChR). This is typically done using radiolabeled ligand competition assays on insect cell membranes expressing nAChRs. The compound's antagonist activity is assessed by measuring its ability to block nAChR-mediated responses.
Cell Assay
In vitro cell-based assays for Flupyrimin involve treating insect cell lines or neurons with the compound and measuring nAChR activity using electrophysiology or calcium imaging. The compound's effects on insect cell viability are also assessed.
Animal Protocol
In vivo animal studies for Flupyrimin involve administering the compound to insects (e.g., pests) and assessing mortality. The compound's efficacy in controlling pest populations is evaluated in agricultural settings. Toxicity to non-target organisms, such as pollinators and rats, is also assessed.
ADME/Pharmacokinetics
Pharmacokinetic properties of Flupyrimin are not extensively detailed in the available literature. The compound is an insecticide. For storage, it should be kept at 2-10°C.
Toxicity/Toxicokinetics
No specific toxicity data for Flupyrimin are available in the provided literature. It is less toxic to pollinators (100 µg/bee) and rats (2000 mg/kg). The compound is for research use only.

Solubility Data
Solubility (In Vitro)
DMSO : ~250 mg/mL (~791.94 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.08 mg/mL (6.59 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL.
Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.

Solubility in Formulation 2: ≥ 2.08 mg/mL (6.59 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 20.8 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.

  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
