Interestingly, an increase of ROS species was observed in each GBM cells uponCancers 2023, 15,11 of 1611 ofcells when compared with all the untreated and H2Ocompoundcells. General, the data recommend with hydrogen peroxide. Similarly, 2-treated 6 created a 4.0-fold increase in SNB19 cells when compared with the untreated and H2 O -treated cells. All round, the data suggest that the considerable boost in ROS production in GBM cells 2was induced by compound 6. The elevated levelthatROS validates compound six as a glutaminase inhibitor, which compound six. in the important increase in ROS production in GBM cells was induced by could The elevated amount of ROS validates compound six as a glutaminase inhibitor, which could be be interlinked using the observed GBM cell death. cell death. interlinked together with the observed GBMAdditionally, the ROS level in LN229 cells treated with compound 6 was higher than thoseFigure 4.
