asterric acid

The Uses of asterric acid

Asterric acid is a fungal metabolite with anti-angiogenic properties, isolated from a number of Aspergillus and Penicillium species. It is an inhibitor of vascular endothelial growth factor (VEGF), inhibiting VEGF-induced tube formation of human umbilical vein endothelial cells.

What are the applications of Application

Asterric acid is an antibiotic, fungal metabolite

Biological Activity

asterric acid is an eta receptor inhibitor.endothelin (et), a potent vasoconstrictor/pressor peptide consisting of 21 amino acid residues, was first isolated from the cultures of porcine aortic endothelial cells. analyses of a human genomic library reveals three forms of et (et-1, et-2 and et-3) with more than 70% homology with one another. in various organs, high affinity and specific receptors for et have been found, which have been classfied as receptors eta and etb. et-1 has potent and long-lasting vasoconstrictive activity, as a result of binding to the eta receptor.

in vitro

previous study asterric acid isolated as an active substance from the culture filtrate of a fungus, aspergillus sp. asterric acid had also been reported as a metabolite of a fungus. it was found that asterric acid had the property of inhibiting et-1 binding to the eta receptor of a10 cells, but it showed no inhibitory activity against anp and a ii binding at 10 mm, which indicated that asterric acid displayed as a specific inhibitor of et-1 binding [1].
