Application

PFI-1 has been used as a bromodomain inhibitor in breast cancer cell line MCF7 dechorionated zebrafish embryos. It has also been used in human peripheral blood mononuclear cells (PBMCs), to inhibit the release of interleukin-6 in lipopolysaccharide (LPS) challenge assay.

Biochem/physiol Actions

PFI-1 is a quinazolinone inhibits androgen receptor (AR) mediated signaling in prostate cancer cells. It elicits minimum toxicity and is effective for anti-HIV-latency therapy. In leukemia cells, PFI-1 inhibits Aurora B kinase and promotes caspase-dependent apoptosis.
Selective BET (bromodomain-containing protein) inhibitor.
The human BET family, which includes BRD2, BRD3, BRD4 and BRDT, play a role in regulation of gene transcription. PFI-1 is a selective BET bromodomain inhibitor with activity at BRD2 (IC50 = 98 nM) and BRD4 (IC50 = 220 nM). For full characterization details, please visit the PFI-1 probe summary on the Structural Genomics Consortium (SGC) website.
