Dimethyldioctadecylammonium (DDA) is a cationic amphipathic lipid. DDA liposomes containing an Ag85B-ESAT-6 antigen induce antigen deposition at an intramuscular or subcutaneous injection site in mice, increasing immune cell exposure to the antigen. In a guinea pig model of M. tuberculosis infection, spleen bacterial load is reduced and lung and spleen lesion numbers are decreased when the mycobacterial lipid antigens Ac2SGL and PIM2 are administered in liposomes comprised of DDA and a synthetic analog of the mycobacterial cord factor trehalose 6,6-dibehenate (TDB). DDA has also been used in the study of lipid bilayer dynamics.

The phosphatidylinositol (PtdIns) phosphates represent a small percentage of total membrane phospholipids. However, they play a critical role in the generation and transmission of cellular signals. PtdIns-(4)-P1 (1,2-dioctanoyl) is a synthetic analog of natural phosphatidylinositol (PtdIns) featuring C8:0 fatty acids at the sn-1 and sn-2 positions. The compound contains the same inositol and diacylglycerol (DAG) stereochemistry as the natural compound. PtdIns-(4)-P1 can be phosphorylated to di- (PtdIns-P2; PIP2) and triphosphates (PtdIns-P3; PIP3). Hydrolysis of PtdIns-(4,5)-P2 by phosphoinositide (PI)-specific phospholipase C generates inositol triphosphate (IP3) and DAG which are key second messengers in an intricate biochemical signal transduction cascade.

Phosphatidylcholine (PC) species are a common class of phospholipids that comprise the mammalian cell membrane. 1,2-Dioctanoyl PC is a synthetic analog of natural phosphatidylcholine species containing saturated C8:O fatty acids in the sn-1 and sn-2 positions of the glycerol backbone. It exhibits a critical micelle concentration (CMC) value of 0.25 mM at 27°C. 1,2-Dioctanoyl PC serves as an efficient substrate for phospholipase D (PLD) as well as sPLA2 isozymes from bovine pancreas and bee venom.

cis-9,10-Methyleneoctadecanoic acid is a cyclopropane fatty acid found in bacteria and the digestive gland of P. globosa, forming a component of S. aureus cell membranes with levels that decrease upon treatment with carvacrol. Secreted by H. pylori, it enhances histamine- and dibutyryl cAMP-stimulated acid secretion in isolated guinea pig parietal cells and activates protein kinase C (PKC) in a calcium-dependent manner.

C18-HSL is one of four lipophilic, long acyl side-chain-bearing N-acylated homoserine lactones (AHLs) produced by the LuxI AHL synthase homolog SinI, involved in quorum sensing signaling in S. meliloti, a nitrogen-fixing bacterial symbiont of the legume [M. sativa]. C18-HSL and other hydrophobic AHLs tend to localize in relatively lipophilic cellular environments and cannot diffuse freely through the cell membrane. These long-chain N-acylhomoserine lactones may be exported from cells by efflux pumps or transported between communicating cells via extracellular outer membrane vesicles. Quorum sensing, a regulatory system used by bacteria to control gene expression in response to cell density, manifests in phenotypes such as biofilm formation and virulence factor production. Coordinated gene expression is achieved through the production, release, and detection of small diffusible signal molecules called autoinducers, including AHLs, which vary in acyl group length (C4-C18), C3 substitution (hydrogen, hydroxyl, or oxo group), and the presence or absence of carbon-carbon double bonds, conferring signal specificity through LuxR family transcriptional regulators. Regulation of bacterial quorum sensing signaling to inhibit pathogenesis represents a novel approach to antimicrobial therapy in treating infectious diseases.
