  • 20-carboxy Arachidonic acid (20-COOH-AA) is the major metabolite of 20-HETE that is produced in renal tubular epithelial, endothelial, and microvascular smooth muscle cell cultures. This ω-oxidation conversion can take place using purified alcohol dehydrogenases three and four or by microsomes containing recombinant human CYP4F3B.{14780} Like 20-HETE, 20-COOH-AA inhibits ion transport in the kidneys. It also produces vasorelaxation of porcine coronary microvessels constricted with endothelin. 20-COOH-AA binds to isolated ligand binding domains of peroxisome proliferator-activated receptor α (PPARα) (Kd = 0.87 ± 0.12 µM) and PPARγ (Kd = 1.7 ± 0.5 µM), and is a dual activator of PPARα and PPARγ in a transiently transfected COS-7 cell reporter system.{14780}

  • 20-ethyl Prostaglandin E2 (20-ethyl PGE2) is an analog of PGE2 in which the ω-chain has been extended by the addition of two methylene carbon atoms. The only well studied prostaglandin analog with this structural feature is unoprostone, an F-series prostaglandin that is clinically approved as a glaucoma medication.{8147} Unoprostone also contains lower side chain modifications (13,14-dihydro-15-keto) which severely limit its affinity for FP receptors, contributing to its lack of potency as a medication. 20-ethyl PGE2 retains the natural 15(S) allylic hydroxyl in the lower side chain, which may improve its potency relative to unoprostone. However, ligand binding assays of this analog with respect to EP or other prostanoid receptors have not been published. E-type prostaglandins have been widely reported to have inflammatory,{5381} cytoprotective,{2216} and a variety of other effects.{1558}

  • Ecdysone is a steroid hormone of the ecdysteroids family which is found in animals (vertebrates and invertebrates) and in plants. There exist different polyhydroxylated forms of ecdysone, the major one being the 20-Hydroxyecdysone. 20-Hydroxyecdysone is known as the insect molting hormone. Indeed, in interaction with the juvenile hormone, 20-hydroxyecdysone plays a key role in growth, development, metamorphosis, and reproduction of the Arthropods (i.e., invertebrates such as insects, crustaceans, arachnids, etc.). Little is known about the function of ecdysteroids in the vertebrates. There are several reports which indicate an effect of the phycoecdysteroid 20-hydroxyecdysone on muscle growth and fat loss in mammals. Some dietary supplements are marketed to enhance physical performances of athletes, and particularly of bodybuilders. Besides, researchers are currently studying the effect of 20-hydroxyecdysone in the treatment of obesity and diabetes. And there are on-going investigations on the possible interest of 20-hydroxyecdysone in the prevention and the treatment of diseases such as osteoporosis and osteoarthritis.

  • The proteasome is a multicatalytic proteinase complex that is involved in the selective degradation of intracellular proteins. The 20S proteasome is the proteolytic core particle of a large protein degradation complex, the 26S proteasome. Proteasome inhibitors exhibit anti-inflammatory and antiproliferative effects, evidence that the proteasome may be an important drug target for the treatment for cancer and inflammatory diseases. Cayman’s 20S Proteasome Assay Kit employs a specific 20S substrate, SUC-LLVY-AMC which, upon cleavage by the active enzyme, generates a highly fluorescent product with an emission wavelength at 480 nm. The kit is easy to use and can be easily adapted to high-throughput screening for therapeutic compounds regulating activation of the 20S proteasome.

  • 24-dehydro Cholesterol-d6 is intended for use as an internal standard for the quantification of 24-dehydro cholesterol (Item No. 14943) by GC- or LC-MS. 24-dehydro Cholesterol is an immediate precursor to cholesterol in the Bloch pathway of cholesterol biosynthesis. Structurally, it varies from cholesterol only by a single double bond at carbon 24 and has been used as cholesterol substitute in cellular membrane studies.{26099} During brain development, 24-dehydro cholesterol transiently accumulates, composing up to 30% of total brain sterol, where it is poised to rapidly enrich membrane sterols.{26098} However, defects in cholesterol synthesis can lead to a condition called desmosterolosis, which results in an accumulation of excess 24-dehydro cholesterol.{26100} 24-dehydro Cholesterol has been reported to activate liver X receptor-target genes in both the liver of cholesterol-free mice and in cholesterol-starved macrophage foam cells in atherosclerotic lesions.{26096,26097}
