Compound 21l, or S1P1 agonist 5, exhibits remarkable in vitro efficacies, demonstrating EC50s for β-arrestin recruitment and internalization of 7.03 nM and 11.8 nM, respectively[1].

ln Vivo |
Oral bioavailability of S1P1 agonist 5 is demonstrated in rats (F=54.2%) and dogs (F=31.8%)[1]. Within a day, lymphopenia can be recovered from when S1P1 agonist 5 (10 mg/kg; po) prevents lymphocyte egress from lymphoid tissue to the peripheral blood[1]. In EAE mice, S1P1 agonist 5 (3, 10 mg/kg, po, once daily for 20 days) reduces the severity of the disease and its overall course, exhibiting positive drug-like characteristics[1].

Animal Protocol |
Animal/Disease Models: rats, male beagle dogs[1]
Doses: Route of Administration: 1 mg/kg for iv and 10 mg/kg for po (rats); 2 mg /kg for iv and 10 mg/kg for po(dogs) Experimental Results: demonstrated good oral bioavaliability in rats (F=54.2%) and dogs (F=31.8%). Animal/Disease Models: male wistar rats (5 week, 160-180 g)[1] Doses: 10 mg/kg Route of Administration: po Experimental Results: Inhibited the lymphocyte egress from the lymphoid tissue to the peripheral blood and that lymphopenia can be recovered within 24 hrs (hours). Animal/Disease Models: female C57BL/6 mice (10 weeks, 19−22 g) (experimental autoimmune encephalitis (EAE) mouse model)[1] Doses: 3, 10 mg/kg (dissolved in 2.5% DMSO and 5% Kolliphor HS 15 (Sigma-Aldrich) in distilled water) Route of Administration: po , one time/day, 20 days Experimental Results: Ameliorated the disease progression and overall severity in EAE mice, showing favorable drug-like properties. |

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.) |

10 mM | 0.2218 mL | 1.1089 mL | 2.2178 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.
