Description: Plasminogen activator inhibitor-1 (PAI-1) inhibitor
Chemical Name: 2-[5-[[6-[5-(1,1-Dimethylethyl)-2-benzoxazolyl]-2-naphthalenyl]oxy]pentyl]propanedioic acid disodium salt
Purity: ≥98% (HPLC)

Biological Activity

Plasminogen activator inhibitor-1 (PAI-1) inhibitor. Inhibits VEGF-induced migration and tube formation in HUVECs. Also attenuates TGF-β dependent epithelial-mesenchymal transition and fibroblast to myofibroblast differentiation in vitro. Reduces size and weight of subcutaneous tumors, and inhibits metastasis and angiogenesis in vivo. Reduces bleomycin-induced pulmonary fibrosis in vivo. Orally bioavailable.
