PROTAC FLT-3 degrader 1 is a PROTAC FLT-3 degrader of internal tandem duplication (ITD) with an IC50 of 0.6 nM and exhibits anti-proliferative activity.
FLT3-IN-13 (compound 20) is a highly effective inhibitor targeting both topoisomerase II and FLT3 proteins in leukemic cells. It exhibits potent activity against these targets, with IC50 values of 2.26 μM for both. Moreover, FLT3-IN-13 induces cell cycle arrest at the G2 M phase and promotes apoptosis. Notably, it displays considerable anticytotoxic activity, specifically against leukemia [1].
FLT3 ITD-IN-1 (Compound 1) is a highly potent inhibitor of FLT3 internal tandem duplications (FLT3-ITD). It exhibits remarkable inhibitory effects against FLT3 and FLT3-ITD, with impressive IC50 values of 38.2 nM and 144.1 nM, respectively. Moreover, FLT3 ITD-IN-1 shows exceptional antiproliferative activities against several acute myeloid leukemia cell lines [1].
