Description
83-01 is a selective inhibitor of TGF-βRI (ALK5), ALK4 and ALK7 (ICK values of ALK5, ALK4 and ALK7 are 12, 45 and 7.5 nM, respectively).

Reprogramming: A 83-01 can reprogram fibroblasts into neural stem cells and cardiomyocytes.

Differentiation: A 83-01 blocks SMAD2/3 phosphorylation and inhibits TGF-β-induced epithelial-to-mesenchymal transition

Maintenance/self-renewal: A 83-01 helps to maintain the homogeneity of iPSC and long-term self-renewal in vitro

Assay Description
83-01 is an effective inhibitor of TGF-βI type receptor ALK5 kinase, ALK4 and ALK7, which can reduce the transcription level induced by ALK-5 in Mv1Lu cells, IC50 is 12 nM, and can also block ALK4-TD and ALK7- The IC50 induced by TD in R4-2 cells was 45 nM and 7.5 nM transcription, and weakly suppressed transcription induced by constitutively active ALK-6, ALK-2, ALK-3 and ALK-1. 83-01 (0.03-10 µM) effectively prevented the growth inhibitory effect of TGF-β, and completely inhibited the effect at 3 µM. 83-01 (1-10 µM) inhibited TGF-β-induced Smad activation in HaCaT cells [1]. TGF-β1 reduced 83-01 (1 µM) cell movement, adhesion and invasion in HM-1 cells, but did not change cell proliferation [2].

Assay Description
83-01 (50, 150 and 500 μg/mouse, intraperitoneal injection) can significantly improve the survival rate of mice without weight or neurobehavior appearance [1]. 83-01 (0.5 mg/kg, i.p.) has a strong antitumor effect on mice with M109 cells [2].

Handling Advice
The compound is sensitive to light. Therefore, we recommend protecting solid materials and solutions from light.
According to reports, A 83-01 can be decomposed into A 77-01 in solution. Therefore, we recommend that you form a solution and use it immediately. Don't store solutions.
If the solution needs to be stored, the solution should be dispensed into sealed vials and stored at -20°C for up to one month.
