Based on 3 publication(s) in Google Scholar
KAG-308 is a potent selective and orally active agonist of EP4 receptor (a prostaglandin E2 receptor subtype), suppresses colitis and promotes histological mucosal healing, potently inhibits TNF-α production. KAG-308 shows a Ki and an EC50 of 2.57 nM and 17 nM for human EP4 receptor, respectively, more selective over EP1, EP2, EP3 and IP receptor.

KAG-308 is a potent selective and orally active agonist of EP4 receptor, suppresses colitis and promots histological mucosal healing. KAG-308 shows a Ki and EC50 values of 2.57 nM and 17 nM for human EP4 receptor, respectively, more selective over human EP1 (Ki, 1410 nM; EC50, 1000 nM), EP2 (Ki, 1540 nM; EC50, 1000 nM), EP3 (Ki, 32.4 nM; EC50, 160 nM) and IP receptor (Ki, 52.9 nM; EC50, >10000 nM). KAG-308 also exhibits potent agonist activity for human and mouse EP4 with an EC50 of 0.15 nM and 1.0 nM, respectively in the dual luciferase reporter assay[1].

Solvent & Solubility
DMSO : 80 mg/mL (173.72 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : < 0.1 mg/mL (insoluble)
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, 6 months; -20°C, 1 month (stored under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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: 6 mg/mL (13.03 mM); Clear solution; Need ultrasonic
This protocol yields a clear solution of 6 mg/mL.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (60.0 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: 6 mg/mL (13.03 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 6 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (60.0 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.
