Biological Activity

Description A-83-01 is a potent inhibitor of TGF-β type I receptor (ALK5-TD) with IC50 of 12 nM. A-83-01 also inhibits the transcription induced by activin/nodal type I receptor (ALK4-TD) and nodal type I receptor (ALK7-TD) with IC50 of 45 nM and 7.5 nM, respectively.Solutions are unstable and should be fresh-prepared.
Targets

(Cell-free assay)
7.5 nM 12 nM 45 nM
In vitro

A-83-01 inhibits the transcriptional activity induced by TGF-β type I receptor ALK-5 and that by activin type IB receptor ALK-4 and nodal type I receptor ALK-7, the kinase domains of which are structurally highly related to those of ALK-5. A-83-01 is potent in the inhibition of ALK5 and also prevents phosphorylation of Smad2/3 and the growth inhibition induced by TGF-β.[1]
In vivo

A83-01 treatment significantly increases the number of Nkx2.5+ cardiomyoblasts at baseline and after myocardial injury, resulting in an increase in newly formed cardiomyocytes. A83-01 treatment significantly improves ventricular elastance and stroke work, leading to improved contractility after injury.[2]

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    Wild-type mink lung epithelial (Mv1Lu) cells, R mutant of Mv1Lu (R4-2) cells, HaCaT cells, C2C12 cells, NMuMG cells

  • Concentrations

    1 μM

  • Incubation Time

    1 h

  • Method

    Cell proliferation assay: Mv1Lu cells are seeded in duplicate at a density of 2.5 × 104 cells/well in 24-well plates. The following day, cells are pretreated for 1 h with 1 μM A-83-01 and then cultured with TGF-β (1 ng/mL) for 24 h, 48 h, or 72 h. Cells are trypsinized and counted with a Coulter counter. To explore whether A-83-01 reduces the growth-inhibitory effects of TGF-β in concentration-dependent fashion, Mv1Lu cells are seeded as above and pretreated for 1 h with various concentrations of A-83-01. After pretreatment, cells are cultured with TGF-β (1 ng/mL) for 48 h and counted.
Animal Study:

[2]
  • Animal Models

    8–10 week old Nkx2.5 enhancer-eGFP transgenic mice

  • Dosages

    10 mg/kg

  • Administration

    IP
