- Product Overview:
Calcitriol-d6 is intended for use as an internal standard for the quantification of calcitriol (Item No. 71820) by GC- or LC-MS. Calcitriol is a vitamin D3 receptor agonist and an active metabolite of vitamin D3 (Item No. 11792).{64736,64735} It is formed via a multi-step process, in which vitamin D3 undergoes hydroxylation to 25-hydroxy vitamin D3 (Item No. 9000683) in the liver, followed by further hydroxylation at the 1?-position in the kidney. Calcitriol binds to the vitamin D3 receptor (Kd = 16 pM) and induces differentiation of U937 acute monocytic leukemia cells (EC50 = 2,000 pM).{64738} It induces cell cycle arrest at the S phase and apoptosis in primary adenomatous and hyperplastic human parathyroid cells when used at a concentration of 10 nM.{64734} Calcitriol (0.65 nmol/animal) increases bone calcium mobilization in chicks on a low-calcium diet.{64735} It stimulates calcium absorption in the intestines in a chick model of rickets induced by a vitamin D3-deficient diet when administered at a dose of 25 µg/animal.{64736} Formulations containing calcitriol have been used in the treatment of hypocalcemia.
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.
