Bobcat339 (Bobcat 339)

Bobcat339 is a potent and selective cytosine-based inhibitor of TET enzyme, with IC50s of 33 μM and 73 μM for TET1 and TET2, respectively. Bobcat339 is useful to the field of epigenetics and serves as a starting point for new therapeutics that target DNA methylation and gene transcription[1].

Bobcat339 is a cell penetrant, potent and selective inhibitor of TET1 and TET2 [Ten-eleven translocation methylcytosine dioxygenase (TET) 1 and 2] th at reduces content of 5-hydroxymethyl-cytosine (5hmC) in cultured neurons. Bobcat339 does not inhibit DNMT3a.

TET1: 33 μM (IC₅₀); TET2: 73 μM (IC₅₀)
