    Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

    After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.

    Direct and indirect high-performance liquid chromatography enantioseparation of trans-4-hydroxy-2-nonenoic acid.[Pubmed: 17416373 ]
    trans-4-Hydroxy-2-nonenoic acid (HNEA) is a marker of lipid peroxidation resulting from the metabolism of trans-4-hydroxy-2-nonenal (HNE). Direct and indirect RP-HPLC methods for the separation of HNEA enantiomers were developed and compared. The indirect method involved pre-column derivatization with a chiral amino agent, (1S,2S)-(+)-2-amino-1-(4-nitrophenyl)-1,3-propanediol, and subsequent separation of diastereomers on a Spherisorb ODS2 column. The direct separation of HNEA enantiomers was performed using the chiral stationary phase, Chiralpak AD-RH. Validation parameters including limit of quantification, linear range, accuracy and precision were determined. The indirect separation method was successfully applied for the determination of enantiomeric ratio of HNEA in rat brain mitochondrial lysate, and showed that HNEA was formed (R)-enantioselectively from HNE.

    4-Hydroxy-trans-2-nonenoic acid is a gamma-hydroxybutyrate receptor ligand in the cerebral cortex and hippocampus.[Pubmed: 15189349]
    Elevated production of 4-hydroxy-trans-2-nonenal (HNE) occurs in numerous neurological disorders involving oxidative damage. HNE is metabolized to the non-toxic 4-hydroxy-trans-2-nonenoic acid (trans-4-Hydroxy-2-nonenoic acid,HNEAcid) by aldehyde dehydrogenases in the rat cerebral cortex. Based upon the structural similarity of HNEAcid to ligands of the gamma-hydroxybutyrate (GHB) receptor, we hypothesized that HNEAcid is an endogenous ligand for the GHB receptor. HNEAcid displaced the specific binding of the GHB receptor ligand (3)H-NCS382 (30 nm) in membrane preparations of human frontal cerebral cortex and whole rat cerebral cortex with IC(50s) of 3.9 +/- 1.1 and 5.6 +/- 1.2 micro m, respectively. Inhibition was attenuated when the carboxyl group of HNEAcid was replaced with an aldehyde or an alcohol. HNEAcid (300 micro m) did not displace the binding of beta-adrenergic receptor and GABA(B) receptor antagonists, demonstrating the selectivity of HNEAcid for the GHB receptor. HNEAcid is formed in homogenates of human frontal cortical gray matter in an NAD(+)-dependent (V(Max), 0.71 nmol/min/mg) and NADP(+)-dependent (V(Max), 0.12 nmol/min/mg) manner. Lastly, (3)H-NCS382 binding is elevated 2.7-fold with age in the cerebral cortex of rats. Our data demonstrate that an HNE metabolite, formed in rat and human brain, is a signaling molecule analogous to other bioactive lipid peroxidation products.
