In mouse models of acute and chronic infection, AN7973 (oral gavage; 5–25 mg/kg; once daily) effectively eradicates C. the body's parvum [1]. In a neonatal calf model of cryptosporidiosis (as seen in infants), AN7973 (oral gavage; 5 mg/kg, 10 mg/kg, 6.67 mg/kg; once daily, twice daily, three times daily) decreases diarrhea, dehydration, and excretion of Cryptosporidium parvum [1]. With its promising safety, stability, and PK characteristics, AN7973 is a promising option for the treatment of cryptosporidiosis [1].

| Animal Protocol |
Animal/Disease Models: NOD scid gamma mice (NOD.Cg-Prkdcscid Il2rgtm1Wjl/SzJ) (NSG)[1] chronically infected with Cryptosporidium for 4 to 5 weeks
Doses: 10 mg/kg, 20 mg/kg Route of Administration: oral Oral administration; 10 mg/kg, 20 mg/kg; one time/day. Experimental Results: Parasite shedding was diminished by >99% at the 25 mg/kg dose, and by >90% at the 10 mg/kg dose. Animal/Disease Models: fourweeks old female C57BL/6 IFN-γ−/− acute Cryptosporidium infection mice [1] Doses: 5 mg/kg, 10 mg/kg, 25 mg/kg Route of Administration: po (oral gavage); 5 mg/kg, 10 mg/kg, 25 mg/kg; single dairy Experimental Results: Elimination of Candida parvum with dose-dependent efficacy. Animal/Disease Models: 1-day to 2-day-old Holstein bull cryptosporidiosis neonatal calf model [1] Doses: 5 mg/kg, 10 mg/kg, 6.67 mg/kg Route of Administration: po (oral gavage); 5 mg /kg, 10 mg/kg, 6.67 mg/kg; one time/day, twice a day, three times a day Experimental Results: diminished parasite shedding and complete elimination of diarrhea. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (5.45 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 (5.45 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. View More
Solubility in Formulation 3: ≥ 2.08 mg/mL (5.45 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.
