Biochem/physiol Actions

AZ12799734 is an orally active TGF-β type I receptors active site inhibitor (ALK1/2/3/4/5/6 Kd = 7.1/6.2/40/1/0.74/0.017 μM) that inhibits ALK5-dependent Smad2 nuclear translocation upon TGF-β1 stimulation (IC50 = 17 nM; MDA-MB-468), as well as ALK1/2/3/6-mediated Smad1 and ALK4/5/7-mediated Smad2 phosphorylation (10 μM; NIH3T3 expressing respective constitutively active receptors). AZ12799734 oral administration in rats results in heart valve lesions (200 mg/kg/day for 5 days) and physeal dysplasia (400 mg/kg/day for 6 days), consistent with a critical role of ALK5 in maintaining the integrity of heart valve and physis.

A novel class of 4-pyridinoxy-2-anilinopyridine-based TGF-beta type I receptor (also known as activin-like kinase 5 or ALK5) inhibitors is reported. The binding mode of this scaffold was successfully predicted by analyzing possible docked binding modes of literature inhibitors and novel

Direct in vivo reprogramming of cardiac fibroblasts into myocytes is an attractive therapeutic intervention in resolving myogenic deterioration. Current transgene-dependent approaches can restore cardiac function, but dependence on retroviral delivery and persistent retention of transgenic sequences are significant therapeutic hurdles.

Aberrant signaling by transforming growth factor-β (TGF-β) and its type I (ALK5) receptor has been implicated in a number of human diseases and this pathway is considered a potential target for therapeutic intervention. Transforming growth factor-β signaling via ALK5 plays

The transforming growth factor β (TGFβ) superfamily includes TGFβ, activins, inhibins, and bone morphogenetic proteins (BMPs). These extracellular ligands have essential roles in normal tissue homeostasis by coordinately regulating cell proliferation, differentiation, and migration. Aberrant signaling of superfamily members, however
