Biological Activity
| ln Vitro | For 72 hours, pyrantel tartrate (10 nM–10 µM) demonstrated strong anti-A antibodies. suum and anti-N (0-168.2 M; 72 h). Activities of American Nus [1][2]. |
| ln Vivo | In hamsters infected with Vibrio ceylonali, pyrantel tartrate (10 mg/kg; po; single dose) can reduce the number of worms, reducing the worm burden by 87.2% and deworming rate to 63.4% [2]. |
| Cell Assay |
Cell viability assay [2] Cell Types: Nepenthes americana Tested Concentrations: 0-168.2 M (0-100 µg/mL) Incubation Duration: 72 hrs (hours) Experimental Results: Inhibitory effect on third-stage larvae and adults of Nepenthes americana, IC50 The values are 2.0 and 7.6 mg/ml respectively. |
| Animal Protocol |
Animal/Disease Models: Male Syrian golden hamster (3 weeks old; A. ceylanicum infection) [2]. Doses: 10 mg/kg Route of Administration: Oral; single. Experimental Results: The worm load reduction rate and deworming rate were 87.2% and 63.4% respectively. |

Solubility Data
| Solubility (In Vitro) | DMSO : ≥ 34 mg/mL (~95.40 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (5.84 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 (5.84 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. Solubility in Formulation 3: ≥ 2.08 mg/mL (5.84 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 20.8 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.) |
