MTT assay result of experimental groups in 100µL (n = 24) solution. The horizontal line within each box represents the mean value of the dataset. Different lowercase letters above the bars indicate significant differences by post-hoc Tukey’s test. ***p < 0.001, **p < 0.01, *p < 0.05 for comparisons between control group with and without the zwitterion analyzed by one-way analysis of variance (ANOVA). Group 1 showed a significantly higher absorbance compared to Group 2,3 and 4 (p < 0.01).
