In vitro cytotoxicity assay. Dose–response effects of AmB–PGA formulation on cytotoxicity against (A) KB cells and (B) RAW 264.7 cells.
Notes: The cells were exposed for 24 hours to various AmB formulations at different drug concentrations. MTT values were normalized to the control cells. The data are reported as the mean ± standard deviation of four experiments. Free drug is pure AmB used in preparation of the complex.
Abbreviations: AmB, amphotericin B; MTT, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide; PGA, polyglutamic acid; AmB-D, Fungizone®; AmB-L, Ambisome®.
