Tranexamic acid is a derivative of aminomethylbenzoic acid, and a kind of antifibrinolytic drugs to stop bleeding. The hemostasis mechanism of tranexamic acid is similar to aminocaproic acid and aminomethylbenzoic acid, but the effect is stronger.  Fibrinolysis, the cleavage of fibrin by plasmin, is a normal step in the dissolution of fibrin clots after wound repair. Tranexamic acid is an inhibitor of fibrinolysis that blocks the interaction of plasmin with fibrin (IC50 = 3.1 μM). It is a lysine mimetic that binds the lysine binding site in plasmin. Antifibrinolytic agents have value when fibrinolytic activity is abnormally high or when coagulation is impaired.

Nervonic Acid is a monounsaturated fatty acid with a 24-carbon backbone and the sole double bond originating from the 9th carbon from the methyl end, with this bond in the cis- configuration. It is a metabolite found in the aging mouse brain. Found in sphingolipids of the white matter of the human brain, neuronic acid is the only magical substance with a dual role in brain development, repairing nerve fibers, unblocking damaged neural pathways in the brain, and promoting nerve cell regeneration. Neuroic acid is very important in the biosynthesis of nerve cell myelin, which together with lignoceric acid accounts for 60% of the acylated fatty acids in white matter sphingomyelin. In demyelinating diseases such as adrenoleukodystrophy and multiple sclerosis, the amount of neuronic acid acylated to sphingolipids is highly reduced, and supplements rich in this fatty acid have been used to help treat these demyelinating diseases.

Bilirubin is a yellow breakdown product of heme catabolism, formed when heme is cleaved by heme oxygenase. This reaction produces carbon monoxide and biliverdin, which is rapidly reduced to bilirubin by biliverdin reductase. Bilirubin has key roles as a free radical scavenger with antioxidant and anti- inflammatory actions. Free and albumin-bound bilirubin can also scavenge nitric oxide (NO) and NO-related species. Unconjugated bilirubin is highly water- insoluble and must be conjugated with glucuronides to become water soluble and subsequently excreted by the liver and kidney.
