Ligand Sp. Action Value Parameter Reference
bromo-deaza-SAH Hs Inhibition 6.0 pKi 2
pKi 6.0 (Ki 9.5x10-7 M) [2]
SGI-1027 Hs Inhibition 6.1 pIC50 1
pIC50 6.1 (IC50 8.5x10-7 M) [1]
Description: Value derived from a nanoscale HTS assay.
Inhibitor Comments
Azacitidine and decitabine are likely to be inhibitors of DNMT1 and DNMT3A. We infer primary target designation from reports of drug action in in vitro and in vivo studies despite the paucity of pharmacological affinity data.
