- Product Overview:
7-keto Cholesterol-d7 is intended for use as an internal standard for the quantification of 7-keto cholesterol (Item No. 16339) by GC- or LC-MS. 7-keto Cholesterol is a bioactive sterol and a major oxysterol component of oxidized LDL.{26766,5829} It is produced by oxidation of cholesterol via ethanol-mediated lipid peroxidation or photodamage as well as oxidation of 7-dehydro cholesterol (Item No. 14612) by the cytochrome P450 (CYP) isoform CYP7A1.{26764,26765,26761} 7-keto Cholesterol inhibits CYP7A1 (IC50 = ~1 ?M).{26765} It induces activation and chemotaxis of retinal microglia as well as polarization to a pro-inflammatory state via NLRP3 inflammasome activation in vitro.{39975} Intraocular implantation of 7-keto cholesterol-coated wafers increases ocular levels of VEGF, IL-1?, and GRO/KC, macrophage infiltration, and neovascularization in rat eye.{39976} Levels of 7-keto cholesterol in lipid deposits are increased in a variety of chronic diseases, including atherosclerosis, Alzheimer’s disease, and age-related macular degeneration.
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.
