Biological Activity

Description

TP0427736 is a potent inhibitor of ALK5 kinase activity with an IC50 of 2.72 nM and this effect is 300-fold higher than the inhibitory effect on ALK3 (IC50 = 836 nM for ALK3). It also inhibits Smad2/3 phosphorylation in A549 cells induced by TGF-β1 with an IC50 value of 8.68 nM.

Targets

ALK5 ^[1]
(Cell-free assay)

2.72 nM

In vitro

TP0427736 inhibits Smad2/3 phosphorylation in a concentration-dependent manner, with an IC50 value of 8.68 nM. In a cell-based assay of outer root sheath cells, TP0427736 rescued the inhibited proliferation by TGF-β1 and TGF-β2 in a concentration-dependent manner^[1].

In vivo

TP0427736 decreases shortening of hair follicle length during the transition from the late anagen phase to the catagen phase^[1].

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines A549 cells Concentrations -- Incubation Time 2 h Method A549 cells are cultured in plates overnight at 37℃ in a 5% CO2, 95% air atmosphere. Cells are pretreated with various concentrations of TP0427736 or DMSO as a control for 2 h, followed by the addition of 1 ng/mL TGF-β1. After 1 h of incubation, the cells are washed with PBS and lysed with RIPA solution, then mixed with biotinylated anti-Smad2/3 antibody. The mixture is transferred to a streptavidin-coated 96 well plate and incubated for 2 h. The mixture is then discarded, and each well is treated with rabbit anti-phosphoserine antibody, followed by Eu-labeled anti-rabbit IgG antibody and DELFIA Enhancement solution. The developed fluorescence is measured using an ARVO multi-label counter. The IC50 values are determined by analyzing the concentration-response curves.
