5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Alofanib (RPT835) is a novel selective allosteric inhibitor of FGFR2 and has a dramatic inhibitory effect with IC50 <10 nM on FGF2-induced phoshphorylation of FRS2a in KATO III cells. It has no direct effect on FGF2-dependent FGFR1 and FGFR3 phosphorylation levels in either cell lines and no effects on FGF2-FGFR2 binding.
Targets
FGFR2 [1]
(Cell-free assay)
In vitro

Alofanib induces mainly apoptosis with cleavage of caspase 3, PARP and Bcl-2 in SKOV3 cell line. Cytotoxic effect of compound on ovarian cancer cells is low[1]. Alofanib inhibits phosphorylation of FRS2α with the IC50 values of 7 and 9 nmol/l in cancer cells expressing different FGFR2 isoforms. In a panel of four cell lines representing several tumour types (triple-negative breast cancer,melanoma, and ovarian cancer), alofanib inhibits FGF-mediated proliferation with 50% growth inhibition (GI50) values of 16-370 nmol/l. Alofanib dose dependently inhibits the proliferation and migration of human and mouse endothelial cells (GI50: 11-58 nmol/l) compared with brivanib and bevacizumab[2].
In vivo

Intravenous alofanib significantly in dose-dependent manner potentiated the efficiency of the combination of paclitaxel and carboplatin. Alofanib suppresses angiogenesis in ovarian cancer mouse model[1]. In a FGFR-driven human tumour xenograft model, oral administration of alofanib is well tolerated and results in potent antitumour activity[2].
