A FTIR spectrum of CD EXO, CUR, CAA, and CD EXO + CAA in the transmission range from 400 to 4000 cm-1. B The morphological changes were observed on KB-3-1 cells and HEp-2 cells treated with the IC50 concentrations of CAA and CD EXO + CAA for 48 h. Scale bar: 10X. C The nuclear fragmentation depicted by DAPI staining of KB-3-1 cells and HEp-2 cells after treatment with CAA and CD EXO + CAA. Scale bar: 10X
