Figure 1. α-Hederin inhibits proliferation of human lung cancer cells. (a) Chemical structure of α-Hederin. (b) Effect of α-hederin on the viability of human lung cancer cells. A549, NCI-H460, and NCI-H292 cells were treated with α-hederin for 48 h. CCK8 assay was performed to analyse cell viability. Results are normalized to PBS controls. (c) Effect of α-Hederin on the viability of non-small cell lung cancer A549 cells. Colony formation of A549 cells treated with α-hederin for 48 h, cultured by DMEM for 10 days, and stained with crystal violet. **p < 0.01 as compared to the 0 μM group. Mean ± S.E.M. n = 3.

Figure 2. α-Hederin dramatically inhibits aerobic glycolysis in A549 cancer cells. Glucose uptake, lactate generation, and intracellular ATP levels in A549 cells in response to α-hederin treatment for 48 h. The concentration of 2-DG was 8 mM. *p < 0.05, **p < 0.01 as compared to the control group. Mean ± S.E.M. n = 3.
