BQ-3020 is a selective endothelin receptor (ETB receptor) agonist that displaces [125I] ET-1 binding to ETB receptors, with an IC50 value of 0.2 nM. BQ-3020 elicits vasoconstriction in the rabbit pulmonary artery. BQ-3020 makes relaxation of the pig urinary bladder neck and can be used for cardiovascular disease research12.

NSC-120011 can be used in the assay to screen proteolytic activities in mite homogenates.

Adrenomedullin (1-50), rat is a 50 amino acid peptide, which induces a selective arterial vasodilation via activation of CGRP1 receptor. Adrenomedullin (1-50) is a peptide hormone with RNA expressed in rat adrenal glands, lung, kidney, heart, and spleen, as well as in the duodenum and submandibular glands.
