ASP5878 is an oral active inhibitor of FGFR 1, 2, 3, and 4, with IC50 values of 0.47 nM, 0.6 nM, 0.74 nM and 3.5 nM for FGFR 1, 2, 3, and 4 kinase activity. ASP5878 has potential antineoplastic activity.

体外研究
ASP5878 shows potent antiproliferative activity in most human HCC cell lines.
ASP5878 inhibits FGFR4 phosphorylation in a concentration-dependent manner. ASP5878 treatment results in the suppression of phosphorylation, mobility shift of FRS2, and suppression of ERK phosphorylation.
Cell Viability Assay
Cell Line:
Human HCC cell lines.
Concentration:
0-1000 nM.
Incubation Time:
5 days.
Result:
HuH-7, Hep3B2.1-7, and JHH-7 cell lines exhibited potent sensitivity to ASP5878, with IC50 values of 27, 8.5, and 21 nmol/L, respectively.
The growth inhibition rate of HLF was 64% and those of other ASP5878-sensitive cell lines were higher than 95% at 1000 nM.
体内研究
ASP5878 (3 mg/kg, orally, once daily) shows antitumor activity in a Hep3B2.1-7 subcutaneous xenograft and HCC orthotopic xenograft mouse model.
ASP5878 induces shrinkage of FGF19-expressing HCC xenograft model.
Animal Model:
Four-week-old male nude mice (CAnN.Cg-Foxn1nu/CrlCrlj [nu/nu]) (Hep3B2.1-7 cells inoculated subcutaneously).
Dosage:
3 mg/kg.
Administration:
Orally once daily from days 14 to 52.
Result:
Induced tumor regression by 9% and 88% at 1 and 3 mg/kg, respectively, without affecting the body weight for 14 days. Induced the suppression of FGFR4 phosphorylation, mobility shift of FRS2, and suppression of ERK phosphorylation.
Animal Model:
HCC orthotopic xenograft model (mouse).
Dosage:
3 mg/kg.
Administration:
Orally once daily for 24 days.
Result:
Exhibited a lower tumor burden than vehicle- and sorafenibtreated mice.
Induced sustained tumor regression without tumor regrowth.
