Selective cytotoxicity of Asc/TETA on various cell lines. MCF-7, MDA-MB-157, MDA-MB-231, U87, HCC-9204, H1299, Hs578Bst, HUVEC, or V79 cells were incubated with 1 mM, 3 mM, or 5 mM of Asc, respectively, along with 10 μM, 30 μM, or 50 μM of TETA to maintain 1 : 100 TETA-to-Asc ratio. MTT assay was performed to assess the cytotoxicity of Asc/TETA on different cell lines after 12 hours of incubation; experiment was repeated three times.
