N-Unsaturated fatty acid amides of tryptophan ester homologues and anti-cholesteric use thereof

摘要

Ethylenically unsaturated fatty acid amides of tryptophan derivatives e.g. alpha -[1-oxo-9-octadecenylamino)]-1H-indole-3-propanoic acid, ethyl ester, are useful as pharmaceutical agents and are obtainable by reacting a mixed anhydride of a long chain unsaturated carboxylic acid with an appropriate tryptophan ester.
