Fig. 1From: In vitro toxic evaluation of two gliptins and their main impurities of synthesisCell viability evaluated by the MTT reduction assays in 3 T3 cells after 24 h incubations with: a sitagliptin – STG, b impurity S1, c impurity S2, d vildagliptin - VLG, e impurity V1, f impurity V2. Results are expressed as mean ± standard error of the mean. Statistical analysis performed through ANOVA/Bonferroni (*p < 0.05; ***p < 0.001 versus control)Back to article page
