Biological Activity
(R)-Ketorolac substantially inhibits growth factor dependent activation of Cdc42 and Rac1 in a dose-dependent manner with an EC50 value of 2.577 μM for Cdc42 and 0.587 μM for Rac1 in SKOV3ip cells[2].
(R)-Ketorolac (1-10 μM) decreases numbers length of filopodia in SKOV3ip cells and reduces SKOV3ip cells adherence to both fibronectin and collagen[2].

Animal Model:C26 tumour-bearing mice[3]
-
Dosage:2 mg/kg
-
Administration:Oral gavage (p.o.), every day after cachexia onset
-
Result:Prolonged survival and alleviates C26-induced weight loss independent of tumour growth and food intake.
Showed a tumour weight of 0.7 g and a weight loss of 0.61 g.
Did not affect C26-associated hepatosplenomegaly and splenic lymphocyte numbers.
Prevented C26-induced T-lymphopenia.

R-Ketorolac (1-100 μM; 48 h). MDA-MB-231 cells are cultured in poly-HEMA-coated dishes in the presence or absence of R-Ketorolac for 48 h, and the cells are collected for anoikis analysis by Annexin V/PI staining. Control and 1 μM R-Ketorolac (R-Ket)-treated groups are used for quantification, and graph data are presented as mean ± SD (n = 3).

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: ≥ 5 mg/mL (19.59 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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: ≥ 5 mg/mL (19.59 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 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.
