Description

General description

A cell-permeable bis(1H-2-indolyl)-1-methanone compound that acts as a highly selective, ATP-competitive and reversible inhibitor of platelet-derived growth factor (PDGF) receptor tyrosine kinase (IC₅₀ = 1.1 M in Swiss 3T3 cells for PDGFR). Also potently inhibits Flt3 (Fms-like tyrosine kinase 3) activity (IC₅₀ = 6.2 M for hPDGFβ-R-mFlt3 and 50 nM in EOL-1 cells). Sensitizes 32D cells to radiation-induced apoptosis and inhibits proliferation of TEL-Flt3-transfected BA/F3 cells (IC₅₀<300 nM). May also serve as a prodrug form of the Platelet Derived Growth Factor Receptor Tyrosine Kinase Inhibitor I in cells.

Prodrug form of Platelet Derived Growth Factor Receptor Tyrosine Kinase Inhibitor I (Cat. No. 521230) that acts as a highly selective, cell-permeable, ATP-competitive, and reversible inhibitor of platelet-derived growth factor receptor (PDGFR) tyrosine kinase (IC₅₀ = 1.1 µM, Swiss 3T3 cells). Also potently inhibits Fms-like tyrosine kinase 3 (Flt3) activity (IC₅₀ = 6.2 µM for PDGFRβ-mFlt3 and 50 nM in EOL-1 cells). Reported to sensitize 32D cells to radiation-induced apoptosis. Also shown to inhibit proliferation of TEL-Flt3-transfected BA/F3 cells (IC₅₀ >300 nM).
