ASB14780 shows selectivity to cPLA2α (IC50 =20 nM) over type II sPLA2 (IC50 >10 μM)[1].
ASB14780 (30 min pre-incucation) inhibits cPLA2α in guinea pig whole blood (GWB) and human whole blood (HWB) in a species-derived differences, with IC50s of 0.54 μM and 0.64 μM, respectively, 15 min after being stimulated by 5 μM calcium ionophore A23187[1].

ASB14780 (50 mg/kg; p.o.; once) suppresses the increase in the ear thickness elicited by the application of TPA (tetradecanoyl phorbol acetate) in mouse[1].
ASB14780 (5 mg/kg; 20 mg/kg; p.o.; once daily) attenuates AHR (airway hyperreactivity), and inhibits IAR (immediate asthmatic response) and LAR (late asthmatic response) in a dose-dependent manner[1].
ASB14780 shows well oral activity of 89.6% in mouse calculated from the ratio of oral administration’s AUC (10 mg/kg; p.o.) and intravenonous administration’s AUC (1 mg/kg; i.v.)[1].

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: ≥ 2.5 mg/mL (4.29 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
