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.

ALA is an essential fatty acid found in leafy green vegetables. ALA, as part of a low saturated fat diet, helps prevent cardiovascular disease. ALA decreases blood pressure, serum cholesterol levels, and platelet aggregation.

8-iso PGE2 isopropyl ester is a more lipophilic form of the free acid, 8-iso PGE2. Prostaglandin esters have enhanced lipid solubility compared to their parent compounds. They are generally hydrolyzed to the free acid upon in vivo administration, making the esters useful prodrugs. In general, the…
