產(chǎn)品描述：

PFI-1 (PF-6405761) is a selective inhibitor of BET for Brd4 and Brd2 with IC50 value of 220 nM and 98 nM, respectively [1].

BET family are transcriptional regulators which consist of Brd2, Brd3, Brd4 and BRDT and play a pivotal role in cell proliferation, cell cycle progression, and apoptosis. It has been shown that Brd4 involves in the survival of many diverse tumors via promoting growth transcription and anti-apoptosis genes. It is well known that BET are epigenetic readers which selectively bind to acetylated lysine residues on histone tails and recently BET inhibitor emerged as important therapy in NUT midline carcinoma and several types of hematopoietic cancers [2, 3].

PFI-1 is a potent BET inhibitor and has a similar selectivity with the reported BET inhibitor JQ1. When tested with BEAS-2Bs cells, PFI-1 treatment markedly suppressed the release of IL-6 and CXCL8 induced by IL-1β/H2O2 by inhibiting Brd4 [4]. In leukaemic cell line MV4 which were sensitive to BET inhibitors, PFI-1 treatment induced cell cycle and apoptosis through function on Brd4 [1]. When tested with NET cell lines, administration of PFI-1 reduced cell proliferation by inhibiting BET activity at low concentrations of 100 nM–1 μM [5].
