Abstract

The gradient-BIRD-method is an effective way to select 13C-bound protons. By changing the phase of the proton pi-pulse, the same sequence can be used to select protons attached to 12C atoms, i.e., for filtering out the 13C-bound protons. These filters, consisting of single or double gradient-BIRDR clusters (BIRD inversion for remote protons) have considerable filtering bandwidth. Because of the efficient suppression of the coupled magnetization, we implemented the gradient-BIRDR filter in HMBC to replace the conventional low-pass filter.

Biosynthetic origin of hydrogen atoms in the lipase inhibitor lipstatin.

The lipase inhibitor lipstatin is biosynthesized in Streptomyces toxytricini via condensation of a C(14) precursor and a C(8) precursor, which are both obtained from fatty acid catabolism. To study the mechanism of this reaction in more detail, S. toxytricini was grown in medium containing a mixture of U-(13)C,U-(2)H-lipids and unlabeled sunflower oil or in a medium containing 70% D(2)O. Lipstatin was isolated and analyzed by (1)H,(2)H, and (13)C NMR spectroscopy. Hydrogen atoms at C-2, C-3, and C-4 of lipstatin were found to be derived from solvent protons. The formation of the lipstatin precursor 3-hydroxy-Delta(5,8)-tetradecadienoyl-CoA by beta oxidation of linoleic acid explains the incorporation of solvent hydrogen into the 4 position of lipstatin. The hydrogen in position 3 of lipstatin is most probably introduced from solvent by proton/deuterium exchange of a redox cofactor involved in the reduction of the keto group in the branched chain beta keto acid arising by a decarboxylative condensation. The incorporation of solvent hydrogen at position 2 can be explained by epimerization of a chiral intermediate at C-2 and C-3. Epimerization may involve a dehydration-rehydration mechanism.

Identification of molecular-cloud material in interplanetary dust particles.

Interplanetary dust particles (IDPs) collected in the Earth's stratosphere and meteorites are fragments of comets and asteroids. These are 'primitive' meteorites in part because they have preserved materials which predate the formation of the Solar System. The most primitive (least altered) meteorites contain a few parts per million of micrometre-sized dust which formed in the atmospheres of giant stars. Some meteorites have elevated D/H and 15N/14N ratios that are attributed to surviving interstellar organic molecules which have probably been strongly diluted and altered by parent-body processes. Most IDPs are chemically, mineralogically, and texturally primitive in comparison to meteorites. Here I show that H and N isotopic anomalies among fragile 'cluster' IDPs are far larger, more common, and less equilibrated than those previously observed in other IDPs or meteorites. In some cases, the D/H ratios that we measure reach the values of interstellar molecules, suggesting that molecular-cloud material has survived intact. These observations indicate that cluster IDPs are the most primitive class of Solar System materials currently available for laboratory analysis.

Complete 1H and 13C NMR assignment of mono-sulfated galactosylceramides with four types of ceramides from human kidney.

The full assignment of 1H and 13C NMR signals of galactosylceramide 3-sulfate (galactosyl sulfatide) and 1H signals of galactosylceramide 6-sulfate was achieved by using 1H-1H DQF-COSY and 1H-13C heteronuclear COSY. Analyses were performed on a mixture of galactosyl sulfatides with four representative ceramide types consisting of a combination of non-hydroxy or 2-hydroxy fatty acids and sphingenine or 4D-hydroxysphinganine (trihydroxysphinganine) as the long-chain bases. The 1H and 13C NMR parameters of galactosyl sulfatide with 4-hydroxysphinganine as well as 13C signals of complex lipids with 4-hydroxysphinganine were elucidated for the first time. Not only sulfation of the galactosyl residue, but also modification of the aglycon, including hydroxylation of fatty acids and hydration of the double bond in sphingoid bases, altered the chemical shifts substantially. In addition, the unique long-range coupling constants, 4J(H,H) and 5J(H,H), in the galactosyl residue of galactosyl sulfatide could be determined.
