Examining
possible methyl bioisosteres at the R1 position.
Chloro, bromo, and trifluoromethyl-substituted derivatives were tested
for inhibition of TET1- or TET2-mediated oxidation of methylated dsDNA.
Each compound was tested at 100 μM in an ELISA. All data presented
are N = 3, error bars indicate ± SEM. Two-way
ANOVA, *P < 0.05, **P < 0.01,
***P < 0.001.
