Biological Activity
| ln Vivo |
- Insecticidal activity against Mythimna separata 3rd-instar larvae: Wilforgine caused toxic effects, with 65% larval mortality at 20 μg/mL after 48 hours (vs. 20% in control). Surviving larvae had 40% reduced body weight vs. control. It damaged muscle microstructure (disrupted fiber arrangement) and ultrastructure (swollen mitochondria, broken myofibrils, increased vacuolation) [2] |
| Animal Protocol |
- Mythimna separata treatment: 3rd-instar larvae were reared at 25±1°C (16L:8D, 70±5% RH). Wilforgine was dissolved in distilled water to 5/10/20 μg/mL; maize leaves were soaked in solutions for 30s, air-dried, and fed to larvae (10 larvae/group, 3 replicates; control: distilled water-soaked leaves). Mortality and body weight were recorded at 24/48h. Thoracic muscle from survivors was fixed, dehydrated, embedded, sectioned, stained, and observed via light/transmission electron microscope [2] |

Solubility Data
| Solubility (In Vitro) | DMSO : ~100 mg/mL (~116.58 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (2.91 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 25.0 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: ≥ 2.5 mg/mL (2.91 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
