Ten-eleven translocation protein (TET) 1 plays a key role in control of DNA demethylation and thereby of gene expression. Dysregulation of these processes leads to serious pathological states such as oncological and neurodegenerative ones and thus TET 1 targeting is highly requested. Therefore, in this work, we examined the ability of hydrazones (acyl-, aroyl- and heterocyclic hydrazones) to inhibit the TET 1 protein and its mechanism of action. Inhibitory activity of hydrazones 1-7 towards TET 1 was measured. The results showed a high affinity of the tested chelators for iron(II). The study clearly showed a significant correlation between the chelator's affinity for iron(II) ions (represented by the binding constant) and TET 1 protein inhibitory activity (represented by IC50 values).
