Ligand Sp. Action Value Parameter Reference
bromo-deaza-SAH Small molecule or natural product Click here for species-specific activity table Ligand has a PDB structure Hs Inhibition 6.0 pKi 3
pKi 6.0 (Ki 9.5x10-7 M) [3]
SGI-1027 Small molecule or natural product Hs Inhibition 6.1 pIC50 2
pIC50 6.1 (IC50 8.5x10-7 M) [2]
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.
Clinically-Relevant Mutations and Pathophysiology Click here for help
Disease:  Cerebellar ataxia, deafness, and narcolepsy, autosomal dominant; ADCADN
OMIM: 604121
Orphanet: ORPHA314404
Disease:  Neuropathy, hereditary sensory, type IE; HSN1E
Disease Ontology: DOID:0050548
OMIM: 614116
General Comments
Based on in vitro analysis, DNMT1 is proposed to bind the ORF8 protein of the SARS-CoV-2 virus [1], although the relevance of this interaction is unclear.
