A 83-01 is a selective TGF-βRI (ALK5), ALK4 and ALK7 inhibitor (IC
50 values are 12, 45 and 7.5 nM at ALK5, ALK4 and ALK7 respectively). It is more potent than SB431542
A 83-01 aids reprogramming of fibroblasts into neural stem cells and cardiomyocytes.
A 83-01 blocks phosphorylation of SMAD2/3 to inhibit TGF-β-induced epithelial-to-mesenchymal transition
Maintenance / self-renewal
A 83-01 helps to maintain homogeneity and long-term in vitro self-renewal of iPSCs
3D growth matrix component and also promotes long-term organoid growth.

forskolin Solubility & Handling
Storage instructions -20°C (protect from light)
Solubility overview Soluble in DMSO (50mM)
This compound is light sensitive; we therefore recommend protecting the solid material and solutions from exposure to light.
It has been reported that A 83-01 can decompose to A 77-01 in solution. We therefore recommend that you make up solutions and use immediately. Do not store solutions.
If storage of solutions is required, you should aliquot out the solution into tightly sealed vials and store at -20°C and store these for up to one month.
