SB-431542 was identified as a TGF-beta receptor type-1 inhibitor (IC50 = 94 nM) by scientists at GlaxoSmithKline. It has subsequently been studied in animal and cell models as a potential cancer treatment, although these efforts have been discontinued. Of note, SB-431542 was also used in a wound healing study where it was found to abolish the improved healing normally enhanced by treatment with Povidone-iodine.

Sample Use Guides
100 random samples were collected from breast cancer patients who had undergone surgical resection. Mice were injected with cell suspensions containing MDA-MB-231-shCon \ MDA-MB-231-shNodal \ MCF-7-Nodal \ MCF- 7-Con. Three days after inoculation mice were dosed with 10 mg/kg of SB-431542 via intraperitoneal injection for four weeks on alternating days. After 4 weeks treatment with SB-431542 demonstrated tumor growth rate inhibition and weekend tumorigenicity.
Route of Administration:
Intraperitoneal
Renal epithelial carcinoma A498 cells were serum starved for 24 h and then treated with various concentrations of SB-431542 for 48 hours to determine cellular toxicity. Cells survived with up tp 10 uM of SB-4831542 for 48 hours, indicating an LD50 > 30 uM. Furthermore, at a concentration of 1 uM SB-242235 was able to prevent the TGF-B–induced nuclear accumulation of Smad
proteins. A dose response curve using 0, 50, 250, 500, and 700 nM SB-431542 was established and an IC50 of 50 nM was reported for inhibition of TGF-B1–induced nuclear fluorescence.
