Effects of HECI and the Lys-substituted analogue on cancer cell lines, a normal cell line and erythrocytes. Cell viability of cancer cell line (A) PC-3, (B) H157, (C) MCF-7 and (D) the normal cell line HMEC-1 at different concentrations of HECI (dark grey) and K9-HECI (light grey). Statistical significance of difference was analysed by two-way ANOVA (*p < 0.05, ****p < 0.0001). (E) Haemolysis rates of HECI and K9-HECI on erythrocytes after being incubated for 4 h. The sample for the 0 μM control group was PBS only.
