Table 3a: Cytotoxicity of RSV on relatively resistant NCI-H460 cells (Dose fixation study). RSV was incubated with cells for 24 h and % cytotoxicity was observed by MTT assay. Cell death was observed in a concentration (0-20 μg/mL) dependent manner in NCI-H460 cells. 10 μg/mL RSV showed 50% cell death (IC₅₀) in NCI-H460 cells.
