Description

PDGFR-IN-1 (compound 7m) is a potent and orally active PDGFR (platelet-derived growth factor receptor) inhibitor, with IC50 values of 2.4 and 0.9 nM for PDGFRα and PDGFRβ, respectively. PDGFR-IN-1 displays robust antitumor effects and low toxicity, and can be used to study osteosarcoma[1].

IC50 & Target

IC50: 2.4 nM (PDGFRα), 0.9 nM (PDGFRβ)[1]
In Vitro

PDGFR-IN-1 (compound 7m) (0-0.4 μM, 48 h) inhibits osteosarcoma cancer cells (U2OS, MG63, MNNG/HOS, and SAOS-2) proliferation and colony formation[1].
PDGFR-IN-1 (0-0.4 μM, 48 h) induces cell-cycle arrest in a dose-dependent manner[1].
PDGFR-IN-1 (0-1.6 μM, 48 h) induces MNNG/HOS and MG63 cell apoptosis in a dose-dependent manner[1].
PDGFR-IN-1 (0-0.4 μM, 15 min) inhibits the expression of α-tubulin in both MNNG/HOS and MG63 cells[1].
PDGFR-IN-1 (0-0.4 μM, 48 h) inhibits PDGFRβ phosphorylation and downstream signaling transduction (p-STAT3, p-AKT, and p-ERK)[1].
PDGFR-IN-1 (0-0.4 μM, 48 h) significantly inhibits osteosarcoma cancer cell migration and invasion by downregulating the expression of FAK, as well as the distribution in the leading edge of cells[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
