Student's t-test was used to test the differences between the two groups. aData are presented as mean ± standard deviation, n = 3. Fold change = IC 50 (GEM-ZZQ)/IC 50 (GEM). GEM-ZZQ indicates the prodrug with an H 2O 2-sensitive thiazolidinone moiety at the 4th amino group of GEM. Abrreviation: GEM, gemcitabine. | |||
