Author(s): Abebe Basazn Mekuria, Zemene Demelash Kifle* and Mohammedbrhan Abdelwuhab
Endothelin is a 21 amino acid molecule endogenous potent vasoconstrictor peptide. Endothelin is synthesized in vascular
endothelial and smooth muscle cells, as well as in neural, renal, pulmonic, and inflammatory cells. It acts through a seven
transmembrane endothelin receptor A (ETA) and endothelin receptor B (ETB) receptors belongs to G protein-coupled
rhodopsin-type receptor superfamily. This peptide involved in pathogenesis of cardiovascular disorder like (heart failure,
arterial hypertension, myocardial infraction and atherosclerosis), renal failure, pulmonary arterial hypertension and it also
involved in pathogenesis of cancer. Potentially endothelin receptor antagonist helps the treatment of the above disorder.
Currently, there are a lot of trails both per-clinical and clinical on endothelin antagonist for various cardiovascular, pulmonary
and cancer disord.. View more»
