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.

A selective calcium ionophore that mobilizes intracellular calcium stores. It is used as a research tool to raise the intracellular level of calcium, to study calcium transport across biological membranes, and to stimulate the intracellular production of cytokines.

A natural sesquiterpene that inhibits the proliferation of a wide range of tumors and enhances the effects of various chemotherapies; 10-40 µg/ml dose-dependently induces apoptosis and cell cycle arrest in the G2/M phase in HepG2 cells, upregulating Fas/FasL expression.

An alkaloid metabolite of nicotine as well as a major product of its pyrolysis; binds comparably to CYP2A6 and CYP2A13 (Kis = 7.5 and 5.6 µM, respectively), but appears to more effectively inactivate CYP2A6.

PPHP is a substrate for the measurement of peroxidase enzymes. PPHP has been used to quantitate the peroxidase activity of COX-1 and COX-2.

11-trans LTC4 is a C-11 double bond isomer of LTC4. LTC4 undergoes slow temperature-dependent isomerization to 11-trans LTC4 during storage. 11-trans LTC4 is produced in smaller amounts relative to LTC4 in ionophore-stimulated HMC-1 cells (a human mast cell line) and equine eosinophils, but not in…
