PFI-6 is a non-cytotoxic and selective MLLT1/3 probe targeting the YEATS domain of MLLT1 (ENL/YEATS1) and MLLT3 (AF9/YEATS3). PFI-6 shows IC50 values of 140 nM and 160 nM for MLLT1 and MLLT3, respectively. PFI-6 can serve as a molecular tool to explore the role of MLLT1/3 in various diseases and related genome validation studies[1].

PFI-6 is a cell penetrantpotent and selective inhibitor of MLLT1/3. PFI-6 binds into the YEATS domain of MLLT1/3.
