Researchers from China Pharmaceutical University have reported the discovery of novel orally bioavailable fms-like tyrosine kinase 3 (FLT3) inhibitors as potential candidates for the treatment of acute myeloid leukemia (AML). Synthesis and optimization of a novel series of FLT3 inhibitors led to the identification of LT-540-717 as the lead candidate.

Although FMS-like tyrosine kinase 3 (FLT3) inhibitors have shown success treating FLT3-mutated acute myeloid leukemia (AML), around 30% to 50% of patients show primary resistance to both type I and type II inhibitors. Therefore, identifying therapeutic strategies to overcome this resistance and enhance the efficacy of FLT3 inhibitors remains an urgent need.

Researchers from Hangzhou Polymed Biopharmaceuticals Inc. have reported the discovery and preclinical evaluation of HPB-092, an FMS-like tyrosine kinase 3 (FLT3) and interleukin-1 receptor-associated kinase 4 (IRAK-4) dual inhibitor, being developed for the treatment of acute myeloid leukemia (AML).
