Dose-response effects of LD and SP6 in undifferentiated SH-SY5Y human neuroblastoma cells. MTT reduction assay in undifferentiated SH-SY5Y human neuroblastoma cells in the presence of LD and SP6. The cells were incubated for 24 or 48 h with increasing concentrations (1, 10, and 100 µM) of the compounds. After this period, cell viability was quantified by measuring MTT reduction. CTRL: control without compounds. The means ± scanning electron microscopy (SEM) were derived from three different experiments (each with n = 16; **** p < 0.0001; ** 0.0005 < p < 0.001; * 0.001 < p < 0.05; n.s., p > 0.05).
