Cell viability assay. a Percentage viability of C6 cells after 72 h of treatment with different concentrations of GBP, VPA and TPM. * Represents statistically significant difference (p < 0.05) between control and drug-treated groups. The experiment was performed in triplicates. b Phase contrast images of C6 control, 50 μm GBP, 10 μm VPA and 10 μm TPM-treated cells. Images were captured using Nikon TE2000 Phase Contrast Microscope. Scale bar represents the length of 200 μm.
