Figure 7. The effects of ergosterol peroxide on tumor cell death.

(a) NMR analysis of the structure of the candidate. (b) Molecular structure, formula and molecular weight of ergosterol peroxide. (c) The MT-1 cells treated with or without ergosterol peroxide were fixed, and stained with the Diff-Quik-Stain kit, followed by microscopic examination and counting of cells survived. Induction of breast cancer cell death by ergosterol peroxide was concentration dependent (Upper). ** 0<0.01, n = 3. Typical vacuoles were detected in the cells treated with ergosterol peroxide (Lower).
