1-Ethyl-3-[3-(dimethylamino)propyl]carbodiimide (EDC) is a water-soluble carbodiimide. EDC is commonly used for the peptide synthesis, protein crosslinking to nucleic acids, preparation of immunoconjugates. EDC is also used in combination with N-hydroxysuccinimide (NHS) for the immobilisation of large biomolecules.

Ethyl linoleate (ELA) is an essential fatty acid used in many cosmetics for its anti-inflammatory properties. It inhibits the action of the reactive species of oxygen released by neutrophils due to an excess of bacteria, and prevents the hyperkeratinization induced by a lack of linoleic acid. Though there are few reports stating the antiinflammatory activity of ELA, the mechanism by which ELA exhibits anti-inflammatory activity remains unclear. An aqueous emulsion of ethyl linoleate can be used as parenteral injection for curring ailments where a high plasma-cholesterol level of the blood is indicated. Improvements in liver function tests during the administration of ELA were noticed in almost all cases with a few aggravated exceptions. The administration of ELA can expect the satisfactory response to the patients both with liver cirrhosis and with chronic hepatitis.

Noopept (DVD-111) is a peptide promoted and prescribed in Russia and neighbouring countries as a nootropic. Noopept was patented by Russian-based pharmaceutical company JSC LEKKO Pharmaceuticals in the 1996. Research shows Noopept has similar effects, but works differently than other nootropics in the racetam-family. The compound is patented in both the US and Russia with patent of Russian Federation number 2119496, U.S. Patent 5,439,930 issued 8/8/1995. Noopept exhibits a combined neuroprotector effect both in vitro and in vivo. Noopept decreases the extent of necrotic damage caused by photoinduced thrombosis of cortical blood vessels. It was established that the neuroprotector effect of noopept is related to its action upon the well-known "triad", whereby the drug reduces neurotoxic effects of excess extracellular calcium, glutamate, and free radicals. Two additional components of the neuroprotector action of noopept are related to the antiinflammatory and antithrombotic activity.
