FLT3/D835Y-IN-1 (compound 13a) (100 nM, 3 h) potently inhibits Ba/F3-FLT3-ITD, Ba/F3-FLT3-ITD/D835Y, Ba/F3-FLT3-ITD-F691L cell lines, and AML cells proliferation[1]. FLT3/D835Y-IN-1 (3-30 nM, 16 h) significantly inhibit FLT3, AKT, ERK, and STAT5 pathways[1]. Cell Proliferation Assay Cell Line: Ba/F3-FLT3-ITD, Ba/F3-FLT3-ITD/D835Y, and Ba/F3-FLT3-ITD-F691L cell lines, AML cells[1] Concentration: 100 nM Incubation Time: 3 h Result: Inhibited Ba/F3-FLT3-ITD, Ba/F3-FLT3-ITD/D835Y, Ba/F3-FLT3-ITD-F691L, MV4-11, MOLM14, and MOLM14-ITD/D835Y proliferation, with GI50 values of 0.59, 0.73, 5.54, 1.30, 6.20, and 4.58 nM, respectively. Western Blot Analysis Cell Line: MOLM14-ITD/D835Y and MOLM14-ITD/F691L cells[1]. Concentration: 3, 10, and 30 nM Incubation Time: 16 h Result: Significantly inhibited the FLT3, AKT, ERK, and STAT5 pathways at lower dosages.

FLT3/D835Y-IN-1 (10 mg/kg, IP, daily, 6 days per week) significantly suppresses tumor growth and exhibits potent antitumor activity against MOLM14-ITD/D835Y cells[1]. FLT3/D835Y-IN-1 (10 mg/kg, IV or Orally, single) displays extremely low AUC and high clearance[1]. Pharmacokinetic Parameters of FLT3/D835Y-IN-1 in ICR mice[1].
