Biological Activity

iP300w is a potent p300/CBP inhibitor, inhibits p300-mediated H3K9 acetylation with IC50 of 33 nM in HTRF assay.
iP300w diminishes DUX4-induced toxicity and inhibits DUX4-mediated transcription.
iP300w blocks DUX4-induced H3 acetylation and prevents the increase in expression of DUX4 target genes, erases the DUX4-mediated transcriptional fingerprint in FSHD myoblasts.
iP300w impairs DUX4-mediated transcription in vivo in the iDUX4pA FSHD mouse model.
