RAW 264.7 cells were treated with a series of I6CA concentrations or LPS (Sigma-Aldrich Chemical Co). After 24 h of incubation, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetra-zolium bromide (MTT) assay was performed as previously described (Hasnn et al. 2019 (link)). The LPS-treated cells were considered a positive control for activating the macrophages. The morphologic changes were observed under a phase-contrast microscope (Carl Zeiss, Oberkochen, Germany).
