Effects of gilteritinib, nintedanib, and imatinib on phospholipidosis (PLD) in ACE2‐A549 cells. Comparison of induction of PLD by gilteritinib, nintedanib, and imatinib versus the positive control amodiaquine. Cells were pretreated with NBD‐PE reagent for 2 h before compound addition. Compounds were added in dose curves and cells were incubated overnight. PLD was quantified using Cell Profiler to measure NBD‐PE signal intensity per nuclei, and values were normalized to the negative control DMSO. EC50 values were calculated in Prism using a variable‐slope four‐parameter model.
