Acrylic Coupling Derivative Acquisition New Acrylic Coupling Derivatives Pharmaceutical Compositions Containing Ss and Their Use in Medicine

摘要

Novel acrylic amide derivative of the formula CHEM wherein R1 represents a hydrogen or a halogen atom or a C1-4alkyl, a C1-4alkoxy or a nitro group. n is an integer of 0 to 2, A represents an amino acid residue derived from a naturally occuring amino acid or an antipode thereof which is connected to the acrylic acyl residue through its amino group; or a residue derived from thiazolidinecarboxylic acid connected to the acrylic acyl group through its nitrogen, or a derivative of the above residues wherein any free carboxy group is esterified with a C1-4alkyl group or is amidated; or A represents a group of formula CHEM wherein R2 is a hydrogen atom or a phenyl, a C1-4alkyl or a C1-4alkoxycarbonyl group, and their salts which have interesting cytoprotective and antiulcer activities are provided. A process is also described for the preparation of said compounds.
