α-Linolenic acid (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.

Angiotensin II is a hormone that plays an important role in regulating blood pressure. Elevated levels of angiotensin II are implicated in inducing and maintaining hypertension, and also in the development of atherosclerosis. Both of these effects are mediated by the angiotensin II type 1 (AT1) receptor. Losartan is a mammalian AT1 receptor antagonist with a Ki value of 5-20 nM. In humans, losartan effectively controls hypertension while protecting renal function. Nitric oxide (NO) causes vasodilation and also inhibits platelet and neutrophil aggregation in the endothelium. NO-losartan A possesses similar anti-hypertensive effects to losartan, with the addition of the vasodilating effects of NO release.

4-hydroxy Valsartan is a major metabolite of the angiotensin II type 1 (AT1) receptor antagonist valsartan . It reduces platelet aggregation induced by epinephrine and collagen but not ADP in human whole blood.

TRAP-6 peptide is a hexapeptide corresponding to residues 42-47 of protease-activated receptor 1 (PAR1). It acts as an agonist of PAR1, inducing platelet aggregation in human platelet-rich plasma ex vivo (EC50 = 0.8 μM). TRAP-6 (0.3 and 0.6 mg kg) has a triphasic effect on mean arterial blood pressure (MAP) in anesthetized rats with a short decrease, an increase, and then a longer decrease in MAP following intravenous administration.

Isoprostanes are produced by the non-enzymatic, free radical peroxidation of phospholipid-esterified arachidonic acid. They have been used as biomarkers of oxidative stress, but they also have been found to have potent biological activity. ent-8-iso-15(S)-Prostaglandin F2α (ent-8-iso-15(S)-PGF2α) is a potent vasoconstrictor of porcine retinal and brain microvessels with EC50 values of 15 and 24 nM, respectively. This isoprostane is about ten-fold more potent than 8-iso-PGF2α in a whole blood platelet aggregation inhibition assay.

15(S)-15-methyl Prostaglandin D2 (15(S)-15-methyl PGD2) is a metabolically stable synthetic analog of PGD2 . In contrast to PGD2, 15(S)-15-methyl PGD2 induces vasoconstriction and increases systemic blood pressure with much reduced inhibitory activity on ADP-induced platelet aggregation. It also exhibits strong antifertility activity in hamsters (200-fold more potent than PGD2).

8-iso PGE2 is one of several isoprostanes produced from arachidonic acid during lipid peroxidation. It is a potent renal vasoconstrictor in the rat. 8-iso PGE2 inhibits U-46619 or I-BOP-induced platelet aggregation with IC50 values of 0.5 and 5 μM, respectively. When infused into the renal artery of the rat at a concentration of 4 μg/kg/min, 8-iso PGE2 decreases the GFR and renal plasma flow by 80% without affecting blood pressure.

16,16-dimethyl PGD2 is a metabolically stable synthetic analog of PGD2. It enhances ADP-induced human platelet aggregation and increases systemic blood pressure in rats.
