Abstract:
The structural characteristics of an immunostimulating agent (3-(5-thioxo-L-prolyl)-L-thiazolidine-4-carboxylic acid) have been established using a combination of 1H and 13C NMR spectroscopy, molecular mechanic calculations (in vacuo and in solution) and X-ray crystallographic analyses. Conformational calculations and NMR spectra identify two classes of conformers, cis and trans, around the peptide bond between the rings, while in the solid state only the cis form has been found.
