Hesperetin is a cholesterol-lowering flavanoid found in a number of citrus juices. It appears to reduce cholesteryl ester mass and inhibit apoB secretion by up to 80%. Hesperetin may have antioxidant, anti-inflammatory, anti-allergic, hypolipidemic, vasoprotective and anticarcinogenic actions. In vitro research also suggests the possibility that hesperetin might have some anticancer effects and that it might have some anti-aromatase activity, as well as activity again. Hesperetin reduces or inhibits the activity of acyl-coenzyme A: cholesterol acyltransferase genes (ACAT1 and ACAT2) and it reduces microsomal triglyceride transfer protein (MTP) activity. Hesperetin also seems to upregulate the LDL receptor. This leads to the reduced assembly and secretion of apoB-containing lipoproteins and enhanced reuptake of those lipoproteins, thereby lowering cholesterol levels. Hesperetin's 7-O-glycoside, hesperidin, is a naturally occurring flavanon-glycoside, the main flavonoid in lemons and sweet oranges.

There has been limited scientific interest in the biological and/or pharmacological application of lauryl fumarate.

Monostearyl fumarate (sodium stearyl fumarate) is a lubricant for use in tablet formulation, it can be used as a taste-masking agent in orally disintegrating tablets. It is a conditioning and stabilizing agent.

Ethyl fumarate is an anti-psoriatic agent. Its salts are used for the treatment of severe psoriasis (Fumaderm formulation). The mechanism of its action is unknown.

Medifoxamine, an antidepressive drug, preferentially inhibits dopamine reuptake. It was marketed in France, but because of the hepatotoxicity, then was withdrawn.

Tilarginine is L-N-monomethyl arginine (L -NMMA), a non-selective inhibitor of nitric oxide synthase (NOS), which has been studied in the treatment of septic shock and cardiogenic shock complicating myocardial infarction. Despite strong evidence that excessive nitric oxide (NO) production plays a pivotal role in the pathogenesis of septic shock and may contribute to the pathogenesis of cardiogenic shock complicating myocardial infarction, outcome studies in these two disorders have proved disappointing. Tilarginine therapy was associated with an excess mortality, particularly at doses > 5 mg/(kg h), in septic shock, whereas the effects of a lower dose (1 mg/(kg h)) in cardiogenic shock complicating myocardial infarction were neutral. The excess mortality in patients with septic shock was almost certainly the result of unfavorable hemodynamic changes induced by Tilarginine (decreased cardiac output, increased pulmonary vascular resistance and reduced tissue oxygen delivery) whereas the lack of benefit in patients with cardiogenic shock complicating myocardial infarction may have been because the dose of Tilarginine was too low.

Calcium Fumarate is a calcium salt of fumaric acid, it can be used as a food supplement. Calcium Fumarate may be used to treat conditions caused by low Calcium levels such as bone loss (osteoporosis), weak bones (osteomalacia/rickets), decreased activity of the parathyroid gland (hypoparathyroidism), and a certain muscle disease (latent tetany). It may also be used in certain patients to make sure they are getting enough Calcium (e.g., women who are pregnant, nursing, or postmenopausal, people taking certain medications such as phenytoin, phenobarbital, or prednisone). Calcium Fumarate is classified by the FDA as a dietary and nutritional additive (21CFR§172.350) and has been used for many years.

3-Aminopropionitrile (Beta-amino-propionitrile, BAPN) is a toxic constituent from lathyrus plants. BAPN found in lathyrus odoratus (our more common garden sweet pea plant) is thought to be responsible for osteolathyrism due to irreversible inhibition of lysyl oxidase (LOX), an enzyme necessary for the covalent cross-linking of tropocollagen molecules during the maturation of mature collagen. BAPN demonstrated in antimetastatic and antimyelofibrotic activity in vivo due to inhibition of LOX.
