The strong reputation of the Swiss Federal institute of Technology (ETH) is based on the fact that, since its foundation well over one hundred years ago, it has played a leading role in the engineering and natural science disciplines. Now, with the f

Interactions and cleavage reactions of ?-amino acids and ?-oligopeptides (up to nine residues, carrying the side chains of Ala, Val, Leu, Ile, Phe, Ser, Lys, and Hop) with biological systems, such as the most potent peptidases (pronase, proteinase K,

Upon treatment with NaH in DMF the homoallylic ethers 1a-g and the amine 1h undergo a rearrangement into the trisubstituted ( E )- olefins 2a-h . Experiments with isotopically labelled forms of 1a and 1b show that the [1,3]-shift is cleanly intramole

The constitution of secalosides A and B was elucidated through NMR spectroscopy using fast 2D-NMR experiments with pulsed-field gradients for coherence selection. Secalosides A and B are epimers at center C-3‘ of aglycon I and have the constitution

The β-hexapeptide (H-β-HVal-β-HAla-β-HLeu)2-OH (2) was prepared from the component L-β-amino acids by conventional peptide synthesis, including fragment coupling. A cyclo-β-tri- and a cyclo-β-hexapeptide were also prepared. The β-amino acids

A mixture of tripeptide isotopomers δ-(L-α-aminoadipyl)-L-cystelnyl-D [2-2H]-valine and δ-(L-α-aminoadipyl)-L-(34S-cysteinyl)-D-valine were converted by the enzyme isopenicillin-N-synthetase into isopenicillin N. The distribution of the 2H and 34

Isotopes are not normally considered to be distinguishable by X-ray crystal structure analysis. There is, of course, no problem as far as neutron diffraction is concerned, as neutron scattering amplitudes vary markedly and irregularly from one nuclid

Under the action of the appropriate synthase from ripe tomatoes a 1∶1 mixture of (3S, 4R)-[3,4-2H2] and (3R, 4S)-[3,4-2H2]-(2S)-adenosylmethionine is transformed into a 1∶1 mixture of the two meso forms of [2H2]-1-aminocyclopropanecarboxylic acid
