Abstract Text A series of 1-H-pyrazole-3-carboxamide derivatives have been designed and synthesized that exhibit excellent FLT3 and CDK inhibition and antiproliferative activities. A structure-activity-relationship study illustrates that the incorporation of a pyrimidine-fused heterocycle at position 4 of the pyrazole is critical for FLT3 and CDK inhibition. Compound 50 (FN-1501), which possesses potent inhibitory activities against FLT3, CDK2, CDK4, and CDK6 with IC50 values in the nanomolar range, shows antiproliferative activities against MV4-11 cells (IC50: 0.008 μM), which correlates with the suppression of retinoblastoma phosphorylation, FLT3, ERK, AKT, and STAT5 and the onset of apoptosis. Acute-toxicity studies in mice show that compound 50 (LD50: 186 mg/kg) is safer than AT7519 (32 mg/kg). In MV4-11 xenografts in a nude-mouse model, compound 50 can induce tumor regression at the dose of 15 mg/kg, which is more efficient than cytarabine (50 mg/kg). Taken together, these results demonstrate the potential of this unique compound for further development into a drug applied in acute-myeloid-leukemia (AML) therapeutics.


  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"


  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.
