Cecropin P1, porcine (0-480 μg/mL, 36-96 h) significantly suppresses CH-1a infection and replication in Marc-145 cells [2]. In addition to exhibiting extracellular virucidal action against PRRSV (porcine reproductive and respiratory syndrome virus) at concentrations of 0-480 μg/mL for 36 hours, cecropin P1, porcine, also has a strong inhibitory impact when administered before to, concurrently with, or following viral inoculation[2]. In the latter stages of infection, cecropin P1, porcine (480 μg/mL, 0–72 h), inhibits the apoptosis caused by CH-1a[2]. Viral particle release is inhibited by cecropin P1, porcine (0-480 μg/mL, 0–4 h)[2].

Cell Viability Assay[2]
Cell Types: Marc-145 cells Tested Concentrations: 160, 320, and 480 μg/mL Incubation Duration: 36, 48, 72, 96 h Experimental Results: Dramatically inhibited viral infection in a dose-dependent manner at 36 h postinfection. Inhibited CH -1a infection in Marc-145 cells with a 50% effective concentration(EC50) of 112 μg/mL. The 50% cytotoxic concentration(CC50) of Cecropin P1 for Marc-145 cells was estimated to be 719 μg/mL. Western Blot Analysis[2] Cell Types: Marc-145 cells Tested Concentrations: 160, 320, and 480 μg/mL Incubation Duration: 36 h Experimental Results: Dramatically decreased the expression of the viral N protein when administered with either the pre-, co-, or posttreatment method. |

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

Oral Formulation 3: Dissolved in PEG400 (Please use freshly prepared in vivo formulations for optimal results.) |

| 5 mM | 0.0588 mL | 0.2942 mL | 0.5884 mL | |
| 10 mM | 0.0294 mL | 0.1471 mL | 0.2942 mL |
*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.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
