Biological Activity
IC50: 9.6 nM (hSSTR5), 57 nM (mSSTR5)[1]
SSTR5 antagonist 1 (compound 25a) (30 μM) inhibits hERG activity by 5.6%[1].
SSTR5 antagonist 1 (10 μM) shows highly selective inhibitory effect on SSTR5 over SSTR1-4, with inhibition rates of 11%, 8%, 14%, 10%[1].
SSTR5 antagonist 1 (1 μM; 15 min and 30 min) exhibits good metabolic stability toward both human and mouse microsomes with in vitro CLint value of <10 μL/min/kg (HLM) and 19 μL/min/kg (MLM), respectively[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
SSTR5 antagonist 1 (100 mg/kg; p.o.; single dose; measured at 0-120 min) augments insulin secretion in a glucose-dependent manner and lowers blood glucose concentration in high-fat diet fed C57BL/6J mice[1].
SSTR5 antagonist 1 (1, 3, 10, and 30 mg/kg; p.o.; single dose) shows dose-dependent effect on glucose excursion measured during the oral glucose tolerance test in HFD fed C57BL/6J mice[1].

Animal Model:High-fat diet fed C57BL/6J mice[1]
-
Dosage:100 mg/kg
-
Administration:Oral gavage; single dose; monitored over 2 h
-
Result:Showed the maximum efficacy superior to that of 10 mg/kg Glibenclamide (HY-15206) and comparable to that of 30 mg/kg Alogliptin (HY-A0023A).
Augmented insulin secretion in a glucose-dependent manner and displayed a blood glucose-lowering effect, indicating its anti-diabetic efficacy in vivo.

Solvent & Solubility
DMSO : 90 mg/mL (175.92 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 2 years; -20°C, 1 year. When stored at -80°C, please use it within 2 years. When stored at -20°C, please use it within 1 year.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.25 mg/mL (4.40 mM); Clear solution
This protocol yields a clear solution of ≥ 2.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (22.5 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.25 mg/mL (4.40 mM); Clear solution
This protocol yields a clear solution of ≥ 2.25 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (22.5 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
