Biological Activity:

UNC669 is a potent and selective small molecule inhibitor for the methyl-lysine (Kme) reading function of L3MBTL1, a member of the malignant brain tumor (MBT) family of chromatin-interacting transcriptional repressors. UNC669 binds L3MBTL1 with a Kd of 5±1 μM (IC50 = 6 ±0.5 μM), exhibiting 5-fold greater affinity than the cognate peptide H4K20Me1, 6-fold selective over its close homologue L3MBTL3 and 10-fold selective over L3MBTL4. The first cocrystal structure of UNC669 bound to L3MBTL1 was determined and provides new insights into binding requirements for further ligand design. UNC669 can serve as a useful chemical tool to interrogate the functions of MBT proteins and probe methyl-lysine reader proteins as a target class.


How to Use:


  • In vitro:  UNC1215 was used at 10-25 µM final concentration in vitro and in cellular assays.
  • In vivo:   n/a
