Human NK cells are enhanced by pentupentin (1-100 μM) without causing cytotoxicity [2]. T-cell and B-cell progenitors undergo phenotypic differentiation when exposed to pentapetin (0.1 ng/mL–10 μg/mL; 3 hours) [3].

| ln Vivo |
Langerhans cell recruitment is accelerated by pendentin (1 mg/kg; intraperitoneally injected three times a week for 7–90 days), which causes the density of Langerhans cells (LC) in mouse skin to approach preconditioning values [ 4]. There is no discernible impact of spleenpentin (0.01-100 μg/mouse; intraperitoneal administration) on neuromuscular transmission in mice [3].

| Animal Protocol |
Animal/Disease Models: Female Balb/c/Bln mice were injected with cyclophosphamide or dexamethasone for 5 days [4]
Doses: 1 mg/kg Route of Administration: intraperitoneal (ip) injection 3 times a week for 7-90 days Experimental Results: Epidermal LC counts reached normal values 28 days after initiation of cyclophosphamide treatment. The dexamethasone treatment group accelerated the recovery process and reached normal skin LC density after 70 days. |

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.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 1.2287 mL | 6.1433 mL | 12.2865 mL | |
| 5 mM | 0.2457 mL | 1.2287 mL | 2.4573 mL | |
| 10 mM | 0.1229 mL | 0.6143 mL | 1.2287 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.
