The undecapeptide physalaemin was investigated by n.m.r. spectroscopy in DMSO solution under acidic and neutral conditions. Large changes of the NH chemical shifts and the temperature gradients of the NH protons occurred on going from pH 3.5 to pH 7.

Two cyclic tetrapeptides [Boc-cyclo(-Xxx-Pro-Asn-Lys-)OMe (Xxx = Asp or Glu)] were synthesized and investigated by NMR spectroscopy. They were designed in order to mimic the salt bridge found in physalaemin. Isomers of the urethane bond were observed

The 5,11b-methanomorphanthridine structure of brunsvigine is unambiguously identified through NMR, CD and mass spectrometry. The structure of brunsvigine is related to the other 5,11b-methanomorphanthridine alkaloids by methylation as well as through

The average vicinal coupling constants of 1-bromo-2-chloroethane at different temperatures have been obtained in a gas-phase 1 H NMR study of 1,2-disubstituted ethanes. Analysis of the experimental data, assuming a ”static” model with constant va

The structure of vermeerin, a sesquiterpenoid dilactone from Geigeria africana Gries, was shown to be I. Vermeerin is the dilactone of the physiologically active vermeeric acid which causes “vomiting disease” among sheep in South Africa.

It is shown that the average coupling constant [Jav = 1 3 (Jt + 2Jg)] for the system CCH2CH(NH2)CO2− derived from different measurements and calculated from data reported in literature does not change appreciably although the molecules contai
