## Synopsis Cyclolinopeptide A, a cyclic nonapeptide isolated from linseed, has lately attracted large interest for i t s cytoprotective activity. The recent elucidation of its solid state structure has prompted us to undertake a detailed conformational analysis in solution. Room-temperature 'H-nm
Nuclear magnetic resonance spectroscopy was combined with X-ray crystallography to determine the solution and solid-state conformations of glyburide (C23H28ClN305S). In solution, there is apparently free rotation about several of the single bonds. Crystals of glyburide belong to space group P2,ln wi
