Enhanced Sonodynamic Antitumor Effect of Ultrasound in the Presence of Nonsteroidal Anti‐inflammatory Drugs
The antitumor effects of non‐steroidal anti‐inflammatory drugs, tenoxicam and piroxicam, against sarcoma 180 cells cultured in 7‐week‐old male mice were examined in vitro under ultrasonic irradiation. The survival rate of tumor cells when tenoxicam or piroxicam was added to sarcoma 180 suspension un...

description | The antitumor effects of non‐steroidal anti‐inflammatory drugs, tenoxicam and piroxicam, against sarcoma 180 cells cultured in 7‐week‐old male mice were examined in vitro under ultrasonic irradiation. The survival rate of tumor cells when tenoxicam or piroxicam was added to sarcoma 180 suspension under ultrasonic irradiation was significantly lower than that when ultrasound alone was applied. Furthermore, when L‐histidine, a scavenger of singlet oxygen and hydroxyl radical, or D‐mannitol, a scavenger of hydroxyl radical, was used concurrently, the survival rate of tumor cells was significantly higher with L‐histidine. From the above findings, it is surmised that tenoxicam and piroxicam increase the antitumor effects of ultrasound by increasing the production of singlet oxygen and other active oxygen species. |
