<p>Endothelin-1 (ET-1) is a peptide that is produced by the endothelium. ET-1 is involved in numerous biological processes, including vasoconstriction, inflammation, and cell proliferation. Endothelin-1 (human ET-1) acetate salt H-Cys-Ser-Cys-Ser-Ser-Leu-Met-Asp-Lys-(Glu)-Cys-(Val)-Tyr-(Phe)-Cys-(His)-Leu -Asp(-Ile)-Ile(-Trp)) acetate salt is a recombinant protein that has been shown to significantly upregulate the production of endothelin in primary pulmonary hypertension. It also plays an important role in bowel disease, where it may be involved in the development of chronic inflammatory bowel disease.</p>

<p>H-His-Arg-OH is a synthetic peptide that has been shown to have cytotoxic effects on mammalian cells. The H-His-Arg-OH peptide can be used for the treatment of heart disease and autoimmune diseases, such as rheumatoid arthritis. This peptide has been found to be resistant to congestive heart failure, which is caused by a number of factors, including hypertension and valvular stenosis. It has also been shown to have an immunoglobulin G1 (IgG1) genotype.</p>
