Sodium lauryl sulfoacetate (Sodium houttuyfonate) is anti-pseudomonas agents, inhibits virulence-related motility of Pseudomonas.

3-Hydroxybutyric acid (Butanoic acid) (or beta-hydroxybutyrate) is a ketone body. Like the other ketone bodies (acetoacetate and acetone), levels of 3-hydroxybutyrate in blood and urine are raised in ketosis. In humans, 3-hydroxybutyrate is synthesized in the liver from acetyl-CoA and can be used as an energy source by the brain when blood glucose is low. Blood levels of 3-hydroxybutyric acid levels may be monitored in diabetic patients to look for diabetic ketoacidosis. Persistent mild hyperketonemia is a common finding in newborns. Ketone bodies serve as an indispensable source of energy for extrahepatic tissues, especially the brain and lung of developing mammals. Another important function of ketone bodies is to provide acetoacetyl-CoA and acetyl-CoA for the synthesis of cholesterol, fatty acids, and complex lipids. During the early postnatal period, acetoacetate (AcAc) and beta-hydroxybutyrate are preferred over glucose as substrates for synthesis of phospholipids and sphingolipids in accord with requirements for brain growth and myelination. Thus, during the first 2 weeks of postnatal development, when the accumulation of cholesterol and phospholipids accelerates, the proportion of ketone bodies incorporated into these lipids increases. On the other hand, an increased proportion of ketone bodies is utilized for cerebroside synthesis during the period of active myelination. In the lung, AcAc serves better than glucose as a precursor for the synthesis of lung phospholipids. The synthesized lipids, particularly dipalmitoylphosphatidylcholine, are incorporated into surfactant, and thus have a potential role in supplying adequate surfactant lipids to maintain lung function during the early days of life (PMID: 3884391 ). 3-Hydroxybutyric acid is found to be associated with fumarase deficiency and medium-chain acyl-CoA dehydrogenase deficiency, which are inborn errors of metabolism.

L-Cysteic acid monohydrate (3-Sulfo-L-alanine Monohydrate) is an oxidation product of L-cysteine that may be used as a competitive inhibitor of the bacterial aspartate: alanine antiporter (AspT) exchange of aspartate and in other aspartate biological systems. L-Cysteic acid monohydrate is used in monomeric surfactant development. L-Cysteic acid monohydrate may be used in studies of excitatory amino acids in the brain, such as those that bind to cysteine sulfinic acid receptors. It is a useful agonist at several rat metabotropic glutamate receptors (mGluRs).

Dipotassium glycyrrhizinate is an anionic surfactant having anti-allergic and anti-inflammatory activities.

1-Hexanol (hexan-1-ol) is a natural product.1-Hexanol, a primary alcohol, is a surfactant that can be employed in industrial processes to enhance interfacial properties[1]. 1-Hexanol uncouples mitochondrial respiration by a non-protonophoric mechanism[2].

Palmitoylcarnitine (Palmitoyl DL-carnitine) is a mitochondrial fatty acid oxidation intermediate that acts as a surfactant.

Ammonium laurate is a surfactant.

1-Monomyristin (2,3-Dihydroxypropyl tetradecanoate) , a 1-monoglyceride of myristic acid, has antibacterial activity against several Gram-positive bacterial strains. 1-Myristoyl-rac-glycerol is used in colloidal chemistry as a nonionic surfactant in the development of micelles.

Monoolein (1-Oleoyl-rac-glycerol) is a surfactant that releases free glycerol and oleic acid upon hydrolysis. Monoolein has been used in liquid crystal studies and research shows that in the presence of monoolein, the penetration of the drug cisplatin (sc-200896) is doubled.
