protac flt3 degrader 1

PROTACFLT3/GSPT1/IKZF1/3 degrader-1 is an FLT3 PROTAC degrader with DC50 = 1.2 nM. It functions as a molecular glue to degrade its brain substrates and exhibits antiproliferative activity against resistant acute myeloid leukemia (AML) cells, showing potential applications in AML research.

PROTACFLT3/JAK2/BRD4 Degrader-1 is a PROTAC degrader targeting FLT3, JAK2, and BRD4, with DC50 values of 5.23 nM, 0.678 nM, and 1.17 nM, respectively. It exhibits potent antiproliferative activity against MV4;11 cells (IC50= 0.79 nM) and FLT3-mutated Ba/F3 cells. Additionally, PROTACFLT3/JAK2/BRD4 Degrader-1 induces apoptosis in MV4;11 cells and demonstrates significant antitumor efficacy in an MV4;11 xenograft model established in NOD SCID mice. This compound is applicable for research in acute myeloid leukemia (AML).

PROTAC FLT3/CDK9 degrader-1, a potent dual degrader of FLT3 and CDK9, effectively induces apoptosis and targets protein degradation of FLT3 and CDK9. This compound holds research potential for FLT3-ITD mutated AML [1].

PROTACFLT3/CDKs degrader-1 (Compound C3) is an agent that degrades cyclin-dependent kinase (CDK2 with a DC50 of 18.73 nM) and FMS-like tyrosine kinase 3 (FLT3). It induces differentiation in HL-60 cells, achieving a 72.77% differentiation rate at 6.25 nM, and inhibits proliferation of acute myeloid leukemia (AML) cells, with an IC50 ranging from 2.9 to 37 nM. PROTACFLT3/CDKs degrader-1 demonstrates potential for improving the treatment of AML.

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 ligand-2 serves as a ligand for the target protein in PROTAC. It is utilized for synthesizing PROTAC FLT-3 degrader 1.

PF15, a selective FLT3-ITD degrader, serves as a PROTAC (proteolysis targeting chimera) tethering ligands for FLT3 kinase and CRBN. It exhibits a degradation concentration 50 (DC50) of 76.7 nM and notably impedes the proliferation of FLT3-ITD-positive cells. PF15 also reduces phosphorylation levels of FLT3 and STAT5 and demonstrates efficacy in inhibiting tumor growth in mouse models, suggesting potential applications in leukemia research [1].

FLT3/CDKs ligand-1 (Compound 14) functions as a ligand for target proteins, promoting the degradation of Cyclin-Dependent Kinases (CDK) and FMS-like tyrosine kinase 3 (FLT3), thereby inhibiting the proliferation and survival of leukemia cells associated with FLT3/CDK. This compound is also used in the synthesis of PROTAC FLT3/CDKs Degrader-1.
