Big endothelin-1 (BET-1) (1-38) is a peptide precursor of endothelin-1 (Item No. 24127) produced by vascular smooth muscle and endothelium.{42221} BET-1 is converted to endothelin-1 by endothelin-converting enzyme (ECE) and to endothelin-1 (1-31) by chymase.{42222} It is also converted to endothelin-1 (1-32) by matrix metalloproteinase-2 (MMP-2).{42221} BET-1 (50 pmol) induces vasoconstriction in isolated rat mesenteric arteries, an effect that is blocked by the MMP-2 antagonist TIMP-2. In vivo, BET-1 (0.1-10 nmol/kg, i.v.) dose-dependently increases blood pressure and bradycardia and leads to renal and hindquarter vasoconstriction in rats as well as abdominal constriction in mice (ED50 = 0.043 mg/kg), effects that are reversed or prevented by the ECE inhibitor phosphoramidon (Item No. 15113).{42223,42224} It also induces mesenteric vasoconstriction in rats.{42223} Unlike endothelin-1, BET-1 (100 pmol/kg, i.v.) increases water and sodium excretion in rats independent of the endothelin A receptor.{42225}

Cayman Chemical’s mission is to help make research possible by supplying scientists worldwide with the basic research tools necessary for advancing human and animal health. Our utmost commitment to healthcare researchers is to offer the highest quality products with an affordable pricing policy.
Our scientists are experts in the synthesis, purification, and characterization of biochemicals ranging from small drug-like heterocycles to complex biolipids, fatty acids, and many others. We are also highly skilled in all aspects of assay and antibody development, protein expression, crystallization, and structure determination.
Over the past thirty years, Cayman developed a deep knowledge base in lipid biochemistry, including research involving the arachidonic acid cascade, inositol phosphates, and cannabinoids. This knowledge enabled the production of reagents of exceptional quality for cancer, oxidative injury, epigenetics, neuroscience, inflammation, metabolism, and many additional lines of research.
Our organic and analytical chemists specialize in the rapid development of manufacturing processes and analytical methods to carry out clinical and commercial GMP-API production. Pre-clinical drug discovery efforts are currently underway in the areas of bone restoration and repair, muscular dystrophy, oncology, and inflammation. A separate group of Ph.D.-level scientists are dedicated to offering Hit-to-Lead Discovery and Profiling Services for epigenetic targets. Our knowledgeable chemists can be contracted to perform complete sample analysis for analytes measured by the majority of our assays. We also offer a wide range of analytical services using LC-MS/MS, HPLC, GC, and many other techniques.
