A 83-01

SKU: orb1304606

Description

A 83-01 is a potent inhibitor of TGF-β type I receptors ALK5, ALK4, and ALK7. It facilitates the generation of induced pluripotent stem cells (iPSCs) from somatic cells and is widely used to support the growth and maintenance of various organoid cultures in vitro.

Bioactivity

• Target IC50:
  ALK5:12 nM|ALK4:45 nM|ALK7:7.5 nM
• In Vivo:
  METHODS: To detect anti-tumor activity in vivo A 83-01 (150 μg/each) was administered intraperitoneally three times a week for four weeks to a B6C3F1 mouse model of peritoneal spread of HM-1 cancer. Results: Ascites formation tended to be slower in the A 83-01-treated group, and A 83-01 significantly improve the survival rate o the mice. METHODS: To investigat the role in myocardial injury, A 83-01 (10 mg/kg) was administered intraperitoneally to Nkx2.5 enh-Cre/mTmG mice once daily for seven days. Results: A 83-01 treatment significantly increase the number of Nkx2.5+ myocardial myofibroblasts at baseline and after myocardial injury, leading to an increase in the number of newly formed myocardial cells. A 83-01 treatment significantly improved ventricular elasticity and stroke work, which led to an improvement of contractility after injury.
• In Vitro:
  METHODS: Wild-type mink lung epithelial cells, Mv1Lu, were treated with A 83-01 (0.03-10 μM) and TGF-β (1 ng/mL) for 48 h, and cell proliferation was detected using a Coulter counter. Results: A 83-01 prevente the Inhibition of Mv1Lu cell growth by TGF-β in a dose-dependent manner. METHODS: Mouse ovarian cancer cells HM-1 were treated with A 83-01 (1-10 μM) for 30 min, followed by treatment with TGF-β (1-10 ng/mL) for 60 min, an the expression levels of target proteins were detected using Western Blot. Results the addition of TGF-β1 increase the expression of pSmad3, and A 83-01 inhibite the up-regulation of TGF-β.
• Cell Research:
  HM-1 cells are seeded into a 96-well plate and are incubated for 18 hr. A-83-01 (1 μM) or Vehicle are then added for 12 hr followed b the addition of TGF-β1 (1 ng/mL) or Vehicle for 60 hr the number of viable cells in Each well is examined usin the WST-1 assay followin the manufacturer's instructions.
