应用
Aurintricarboxylic acid is employed as a powerful inhibitor of cellular processes, including apoptosis, that are dependent on the formation of protein-nucleic acid complexes. It binds to a FGF and reduces its angiogenic activity. Aurintricarboxylic Acid has been shown to inhibit apoptotic cell death in various cell types induced by a variety of factors. It Inhibits protein-nucleic acid interactions. It stimulates the tyrosine phosphorylation of MAP kinases.

一般描述

A cell-permeable polyanionic, polyaromatic compound used as a powerful inhibitor of cellular processes that are dependent on the formation of protein-nucleic acid complexes. Shown to inhibit apoptotic cell death in various cell types induced by a variety of factors. ATA is also a potent inhibitor of DNA topoisomerase II. Inhibits von Willebrand factor binding to platelets and reduces glutamate-induced neuronal injury. ATA has been reported to stimulate the tyrosine phosphorylation of MAP kinases, Shc proteins, phosphatidylinositol 3-kinase, and phospholipase C-γ. Dye content: ~85%.

Binds to aFGF and reduces its angiogenic activity. Shown to inhibit apoptotic cell death in various cell types induced by a variety of factors. ATA is a potent inhibitor of DNA topoisomerase II (IC₅₀= 75 nM for the yeast enzyme as measured by relaxation assays) that also acts as a potent inhibitor of angiogenesis. Inhibits von Willebrand factor binding to platelets and reduces glutamate-induced neuronal injury. ATA stimulates the tyrosine phosphorylation of MAP kinases, Shc proteins, phosphatidylinositol 3-kinase, and phospholipase Cγ. Inhibits both major calpain isoforms (IC₅₀ = 22 µM and IC₅₀ = 10 µM for µ-calpain and m-calpain, respectively).
Dye content: ~85%.
