Genital tract epithelial cells are not cytotoxically affected by stampidine (7.8–1,000 μM; 24 hours) [2]. In cervical mucous, stampidine has no influence on sperm motility [2].

| ln Vivo |
Oral stampidine (50–100 mg/kg) has strong antiretroviral effects in cats infected with the feline immunodeficiency virus (FIV) [3]. In dogs, Stampidine (100 mg/kg; po) had the following mean plasma Cmax, AUC, half-life (t1/2), and mean residence time (MRT) values: 15.4 µM, 23.1 µM·h, 108.6 min, and 119.4 min, respectively [ 4]. In adult beagle dogs, stampidine does not elevate ALT, AST, or Alk levels; it also does not produce anemia, thrombocytopenia, neutropenia, or lymphopenia (suggesting hematological toxicity), increases in BUN or creatinine, or electrolyte changes (suggesting nephrotoxicity or metabolic abnormalities)[4].

| Animal Protocol |
Animal/Disease Models: SPF male or female domestic cat (2.9-6.2 kg), chronic FIV infection [3]
Doses: 50 mg/kg, 100 mg/kg Route of Administration: Oral (oral bolus dose) Experimental Results: Demonstrated effective Antiretroviral activity. Animal/Disease Models: Male Beagle (10-12 kg) [4] Doses: 100 mg/kg (pharmacokinetic/PK/PK analysis) Route of Administration: Oral Experimental Results: Estimated mean plasma Cmax and AUC values were 15.4 µM and 23.1 µM, respectively ·h. The mean elimination half-life (t1/2) and mean residence time (MRT) were 108.6 minutes and 119.4 minutes, respectively. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 0.83 mg/mL (1.52 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 8.3 mg/mL clear DMSO stock solution to 400 μL of PEG300 and mix evenly; then add 50 μL of Tween-80 to the above solution and mix evenly; then add 450 μL of 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: ≥ 0.83 mg/mL (1.52 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 8.3 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. View More
Solubility in Formulation 3: ≥ 0.83 mg/mL (1.52 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), 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.
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.
