ISM7594
ISM7594 is an orally active FGFR2/3 inhibitor. ISM7594 shows broad-spectrum antiproliferative potency in FGFR2- or FGFR3-altered cancer cell panels, including FGFR2/3 amplification, fusion, and mutation (BaF3-TEL-FGFR2-V564F (IC50 = 0.067 nM), BaF3-TEL-FGFR2-V564I (IC50 = 2 nM)) types. ISM7594 inhibits tumor growth in a dose-dependent manner. ISM7594 can be used for the study of advanced solid tumors with FGFR2/3 aberrations.

FGFR1 118.4 nM (IC50) |
FGFR2 1.7 nM (IC50) |
FGFR3 12.4 nM (IC50) |
FGFR4 3066 nM (IC50) |
ISM7594 (0.01-1000 nM) exhibits markedly superior inhibitory activities against FGFR2 (IC50 = 1.7 nM) and FGFR3 (IC50 = 12.4 nM) compared to the benchmark RE1[1]. ISM7594 (0.01-1000 nM) shows strong inhibitory activity against multiple FGFR2 mutants (V564I (IC50 = 4.4 nM), V564F (IC50 = 0.22 nM))[1]. ISM7594 demonstrates a higher epithelial permeability and a lower efflux ratio in the Caco-2 assay[1]. ISM7594 (0.152-1000 nM, 2 h) effectively suppresses the phosphorylation of FGFR and ERK in gastric adenocarcinoma (SNU-16) and bladder carcinoma (RT4) cells[1]. ISM7594 (10 μM, 72 h) demonstrates potent antiproliferative activity against in the gatekeeper mutant FGFR2/3 in BaF3 cells (BaF3-TEL-FGFR2 (IC50 = 0.17 nM), BaF3-TEL-FGFR3 (IC50 = 14 nM), BaF3-FGFR3-TACC (IC50 = 81 nM), BaF3-TEL-FGFR2-V564F (IC50 = 0.067 nM), BaF3-TEL-FGFR2-V564I (IC50 = 2 nM), BaF3-FGFR3-TACC3-G370C-K650E (IC50 = 34.7 nM)), gastric cancer cells (KATO-III (IC50 = 3.97 nM), SNU-16 (IC50 = 1.6 nM), SNU1 (IC50 = 3.69 nM)), breast cancer cells (SUM52PE (IC50 = 5.5 nM), MCF-7 (IC50 = 8.77 μM)), endometrial cancer cells (AN3CA (IC50 = 7.18 nM), MFE280 (IC50 = 73.7 nM)), bladder cancer cells (RT112-84 (IC50 = 19.8 nM), RT4 (IC50 = 13.9 nM), UM-UC-14 (IC50 = 71 nM), T24 (IC50 = 5.86 μM), UM-UC-3 (IC50 = 8.21 μM)), multiple myeloma (OPM-2 (IC50 = 81.6 nM), U266 (IC50 = 5.28 μM)) and liver cancer (Li-7 (IC50 = 2.34 μM))[1]. ISM7594 (1000 nM) selectively inhibits FGFR1, achieving a 92.9% inhibition rate[1].
