Cell lines

Pancreatic cancer cell lines, A549 and H460 cells, non-small cell lung cancer cells

Preparation method

The solubility of this compound in DMSO is >22.4mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

Animal models

C57BL/6 mouse model of endotoxemia

Dosage form

Intraperitoneal injection, 5 mg/kg, 2 h

Application

In a C57BL/6 mouse model of endotoxemia, pre-treatment with CAY10603 significantly inhibited endotoxin-induced caspase-3 activation and attenuated endotoxin-induced lung edema formation in the lung tissues.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
