D-myo-Inositol-1,4,5,6-tetrahosphate (sodium salt) (Ins(1,4,5,6)-P4) is one of several different inositol oligophosphate isomers implicated in signal transduction. Production of Ins(1,4,5,6)-P4 by intestinal epithelial cells increases approximately 2-14 fold, depending on the strain and incubation time, following infection with Salmonella.[1] D-myo-Inositol-1,4,5,6-tetraphosphate (sodium salt) (Ins(1,4,5,6)-P4) is one of several different inositol oligophosphate isomers implicated in signal transduction. Production of Ins(1,4,5,6)-P4 by intestinal epithelial cells increases approximately 2-14 fold, depending on the strain and incubation time, following infection with Salmonella. Ins(1,4,5,6)-P4 antagonizes epidermal growth factor (EGF) signalling through the phosphatidylinositol 3-kinase pathway. Ins(1,4,5,6)-P4 (tested as the D L racemic mixture) is ~1,000-fold less potent than Ins(1,4,5)-P3 at initiating Ca2+ release when injected into Xenopus oocytes.[2]

Nitrated unsaturated fatty acids, such as 10- and 12-nitrolinoleate , cholesteryl nitrolinoleate, and nitrohydroxylinoleate, represent a new class of endogenous lipid-derived signalling molecules. LNO2 isomers serve as potent endogenous ligands for PPARγ and can also decompose or be metabolized to release nitric oxide. 9-Nitrooleate is one of two regioisomers of nitrooleate, the other being 10-nitrooleate (OA-NO2; used for the mixture of isomers), which are formed by nitration of oleic acid in approximately equal proportions in vivo. Peroxynitrite, acidified nitrite, and myeloperoxidase in the presence of H2O2 and nitrite, all mediate the nitration of oleic acid. OA-NO2 is found in human plasma as the free acid and esterified in phospholipids at concentrations of 619 ± 52 nM and 302 ± 369 nM, respectively. OA-NO2 activates PPARγ approximately 7-fold at a concentration of 1 μM and effectively promotes differentiation 3T3-L1 preadipocytes to adipocytes at 3 μM.

Ins(1,2)P2 (sodium salt) is one of the many inositol phosphate (InsP) isomers that could act as small, soluble second messengers in the transmission of cellular signals. The most studied InsP Ins(1,4,5)P3, is a second messenger produced in cells by phospholipase C (PLC)-mediated hydrolysis of phosphatidylinositol-4,5-biphosphate. Binding of Ins(1,4,5)P3 to its receptor on the endoplasmic reticulum results in opening of the calcium channels and an increase in intracellular calcium. Ins(1,2)P2 (tested as the D L racemic mixture) is ~1,000-fold less potent than Ins(1,4,5)P3 at initiating Ca2+ release when injected into Xenopus oocytes.
