Chemical structure
| Description | A 83-01 is a selective inhibitor of TGF-β type I receptor ALK5 kinase, type I activin/nodal receptor ALK4 and type I nodal receptor ALK7 with IC50 values of 12 nM, 45 nM and 7.5 nM, respectively. | |||||
| Targets | ALK5 | ALK4 | ALK7 | |||
| IC50 | 12 nM | 45 nM | 7.5 nM | |||
| Cell experiment [1]: | |
Cell lines | Mv1Lu and C2C12 cells |
Preparation method | The solubility of this compound in DMSO is > 21.1 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months. |
Reacting condition | 0.01 ~ 10 μM; 1 hr |
Applications | In Mv1Lu cells, A-83-01 reduced the level of TGF-β-induced transcription in a concentration-dependent manner, with the IC50 value of 25 nM. On the other hand, for BMP-induced transcriptional activity in C2C12 cells, A-83-01 showed no effect at the dose of 1 μM. However, at the concentrations over 3 μM, A-83-01 slightly suppressed the transcriptional activity induced by BMP4. |

A 83-01 is a small-molecule inhibitor of activin receptorlike kinase (ALK)-5 with IC50 value of 12 nM [1].
A 83-01 inhibited 68% of the transcriptional activation induced by ALK-5 at concentration of 1 μM in Mv1LuR4-2 cells that transfected with luciferase reporter gene and constitutively active ALK-5. In cells transfected with luciferase reporter gene only, A 83-01 treatment inhibited the activity of ALK-5 induced by TGF-β (IC50 value was 12 nM) but not BMP. A 83-01 also showed inhibition on the activity of ALK-4 and ALK-7 in R4-2 cells with IC50 values of 45 and 7.5 nM, respectively. For other ALK receptors such as ALK-1, 2, 3 and 6, A 83-01 showed weak inhibition. Besides that, A 83-01 was proved to reduce the cell growth inhibition [1].
