Product namePD 173074, FGFR1 and FGFR3 inhibitor
DescriptionPotent FGFR1 and FGFR3 inhibitor
Biological descriptionPotent, ATP-competitive fibroblast growth factor receptor 1 (FGFR1) and FGFR3 inhibitor (IC50 values are 21.5 and 5 nM respectively). Shows little activity at EGFR, InsR, MEK and cPKC. Effectively inhibits angiogenesis in vivo. Also impairs tumor growth and inhibits self-renewal of stem cells.
Storage instructionsStore at +4°C. The product can be stored for up to 12 months.
Solubility overviewSoluble in DMSO to 100 mM and in ethanol to 100 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Our Abpromise guarantee covers the use of ab141117 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|Functional Studies||Use at an assay dependent concentration.|
BT549 cells were incubated at 37ºC for 1 hour with vehicle control (0 µM) and different concentrations of PD 173074 (ab141117) in DMSO. Decreased expression of RSK1 p90 (phospho T359 + S363) ab32413 correlates with an increase in PD 173074 concentration, as described in literature.
Whole cell lysates were prepared with RIPA buffer (containing protease inhibitors and sodium orthovanadate), 10 µg of each were loaded on the gel and the WB was run under reducing conditions. After transfer the membrane was blocked for an hour using 5% BSA before being incubated with ab32413 at 1/5000 dilution and ab8227 at 1 μg/ml overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP ab97051 at 1/10000 dilution and visualised using ECL development solution.
