PDB Ligand Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: Lestaurtinib was identified as an inhibitor of the receptor tyrosine kinase (RTK) FLT3 (fms-related tyrosine kinase 3) with activity against leukemia cells in vitro and in vivo [2]. It has activity against other RTKs. A drug repurposing sceen for breast cancer has identified lestaurtinib as a promising agent which appears to sensitise BRCA mutant and wild type breast cancer cells to the effects of the Poly (ADP-ribose) polymerase 1 (PARP1) inhibitor AG14361 [3].
