Our results showed that NSC-311068 (6-(1-Pyrrolidinyl(3,4,5-trimethoxyphenyl)methyl)-1,3-benzodioxol-5-ol; C21H25NO6) and NSC-370284 (Pyrimidine, 4-[(2,4-dinitrophenyl)thio]-; C10H6N4O4S) exhibited the most significant effects in inhibiting cell viability of all four TET1-high AML cell lines, whereas showing no significant inhibition on viability of NB4/t(15;17) AML cells, a control cell line with very low level of TET1 expression (Fig. 1a, b). This evidence concerns the gene TET1 and acute myeloid leukemia.
