NPS-467 (R-enantiomer) (0.25-8.0 mg/kg; intraperitoneal injection; single dose) can stereospecifically, dose-dependently and time-dependently stimulate STC secretion in juvenile rainbow trout, with an ED50 of 0.44 mg/kg, and serum STC levels can be increased up to 9-fold, without affecting serum CT levels [1]. NPS-467 (R-enantiomer) (0.25-2.0 mg/kg; intraperitoneal injection; single dose) can stereospecifically and dose-dependently inhibit gill calcium transport in juvenile rainbow trout by enhancing STC release, with an ED50 of 0.5 mg/kg, and this inhibitory effect can be completely blocked by fish STC antiserum [1].

| Animal Protocol |
Animal/Disease Models:Rainbow trout (juveniles, 150-250 g)[1]
Doses: 0.25 mg/kg; 0.5 mg/kg; 1.0 mg/kg; 2.0 mg/kg Route of Administration: Intraperitoneal injection; single dose Experimental Results: Statistically significant stimulation of STC secretion (P < 0.01-0.001). Serum STC levels increased to a maximum of 2069 ng/mL, 9 times higher than the control group; the effect tended to stabilize after the dose exceeded 2.5 mg/kg. The ED50 for stimulating STC secretion was 0.44 mg/kg. A rapid response was generated after injection, with STC induction levels reaching up to 14 times within 0.5 hours after injection, and the effect could last up to 4 hours. At doses of 0.25, 0.5, 1.0, or 2.0 mg/kg, no statistically significant effect was observed on serum CT levels. Animal/Disease Models:Rainbow trout (juveniles, 1-2 g)[1] Doses: 0.25 mg/kg; 0.5 mg/kg; 1.0 mg/kg; 2.0 mg/kg Route of Administration: Intraperitoneal injection; Single dose Experimental Results: Dose-dependent inhibition of GCAT was observed in all three experiments, with statistically significant reductions observed at all tested doses (P < 0.05-0.01). The ED50 for GCAT inhibition was 0.5 mg/kg (2.5 μmol/kg), similar to the ED50 for STC secretion stimulation. Passive immunization with fish STC antiserum completely neutralized the inhibitory effect on GCAT (2.0 mg/kg), and GCAT levels were not significantly different from the control group that received only non-immunized rabbit serum. |

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.) |

*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.
