The CysLTs, LTC4 and LTD4, are potent mediators of asthma and hypersensitivity. They induce bronchoconstriction, increase microvascular permeability, and are vasoconstrictors of coronary arteries. Their biological effects are transduced by a pair of GPCRs, CysLT1 and CysLT2. Montelukast (sodium…

An acylated amino acid that is used as a urinary biomarker for several indications; increased urinary excretion is indicative of MCAD deficiency; can also be used as a biomarker for exposure to gamma radiation.

A derivative of AMP that has been used in the synthesis of novel photoaffinity labels for incorporation into DNA and to study adenosine-based interactions during DNA synthesis and DNA damage.

An antimycotic prodrug that is converted by cytosine deaminase to 5-fluorouracil, a cytotoxic drug that inhibits viral infections and has cytotoxic effects on cancer cells.

Oleic acid is a monounsaturated fatty acid and is one of the major components of membrane phospholipids. Oleic acid contributes about 17% of the total fatty acids esterified to phosphatidylcholine, the major phospholipid class in porcine platelets. Oleic acid inhibits collagen-stimulated platelet…

DGLA is a metabolite produced by chain elongation of the essential fatty acid γ-linolenic acid. Ethyl DGLA is an esterified version of the free acid which is less water soluble, but more ammenable for the formulation of DGLA-containing diets and dietary supplements. DGLA has been advanced as…

A chemiluminescent substrate of firefly luciferase which produces light upon oxidative decarboxylation in the presence of ATP.

A cell-permeable, water-soluble derivative of vitamin E with potent antioxidant properties; commonly used as a standard or positive control in antioxidant assays.

An elongation product of γ-linolenic acid (18:3), rapidly metabolized by fatty acid desaturases to produce arachidonic acid (20:4); metabolized through the cyclooxygenase pathway to produce 1-series prostaglandins; can reduce atopic dermatitis and atherosclerosis when added to the diet of mice.

A major organic tracer generated by burned cellulose; used to evaluate, in atmospheric samples, the burning of wood.

A class III antiarrhythmic agent; inhibits KCNH2 with an IC₅₀ value of 1 µM; also inhibits CYP2C8 and CYP3A4 in vitro at low micromolar concentrations.

A cell permeable derivative of GSH that undergoes hydrolysis by intracellular esterases to release GSH; used to protect cells against damage from radiation, oxidants, and various toxic compounds including heavy metals.

EPA is an ω-3 fatty acid abundantly available in marine organisms. It is a poor substrate for COX-1. EPA has been shown to offer protection against coronary heart disease, thrombosis, ischemic brain injury, scaly dermatitis, and some inflammatory diseases.

2-Tert-butyl-4-hydroxyanisole (2-BHA) is one component of butylated hydroxyanisole (BHA). This compound is commonly used as a food additive; it exhibits antioxidative activity. 2-BHA acts as a phase II enzyme inducer, increasing levels of glutathione and glutathione-S-transferase.

A fluorogenic substrate of β-glucuronidase that upon cleavage yields a blue fluorescent end product that can be monitored by UV light; typically used in the GUS reporter system for fluorescent detection of β-glucuronidase gene expression in E. coli and transformed plants.

A steroid hormone produced in the cortex of the adrenal glands that binds to both glucocorticoid and mineralocorticoid receptors; also is the precursor to aldosterone synthesis.

An irreversible inhibitor of ornithine decarboxylase that suppresses polyamine biosynthesis; displays antiangiogenic, cytostatic, and antiparasitic effects.

A cytotoxic, quinoline alkaloid that inhibits the DNA enzyme topoisomerase I (Top I) by binding the Top1-DNA cleavage complex and inducing DNA-strand breaks; has strong anti-tumor activity and induces DNA damage at concentrations as low as 51 nM in whole cells and 12 nM in isolated nuclei in in…
