Acute myeloid leukemia (AML) is a clonal disorder of hematopoietic progenitor cell. In AML, a mutation in FLT3 is commonly occurs and is associated with poor prognosis. We have previously reported that thieno[2,3-d]pyrimidine derivative compound 1 exhibited better antiproliferative activity against MV4-11 cells which harbor mutant FLT3 than AC220, which is a well-known FLT3 inhibitor, and has good microsomal stability. However, compound 1 had poor solubility. We then carried out further structural modification at the C2and the C6positions of thieno[2,3-d]pyrimidine scaffold. Compound 13b, which possesses a thiazole moiety at the C2position, exhibited better antiproliferative activity than compound 1 and showed increased solubility and moderate microsomal stability. These results indicate that compound 13b could be a promising potential FLT inhibitor for AML chemotherapy.
