“…Medium containing the compound was changed every 2 days. The cell viability was measured by MTT assay (Stockert, Blazquez-Castro, Canete, Horobin, & Villanueva, 2012), and the cytotoxic response of RAW264.7 was evaluated by trypan blue exclusion (Shih, Kuo, Chuang, Cheng, & Doong, 2000). The 50% and 10% inhibitory concentrations of the compound were calculated using the formula: %IC = [1-(A 570test /A 570cont )] × 100, where % IC = % inhibition of cell proliferation, A 570test = absorbance of test sample, A 570cont = absorbance of control sample (Cetin & Bullerman, 2005).…”
