Novel acrylic amide derivatives of the Formula (I) ##STR1## wherein R.sup.1 represents a hydrogen or a halogen atom or a C.sub.1-4 alkyl, a C.sub.1-4 alkoxy or a nitro group. n is an integer of 0 to 2, A represents an amino acid residue derived from a naturally occurring amino acid or an antipode thereof which is bonded to the acrylic acyl residue through its amino group; or a residue derived from thiazolidinecarboxylic acid, bonded to the acrylic acyl group through its nitrogen, or a derivative of the above residues wherein any free carboxy group is esterified with a C.sub.1-4 alkyl group or is amidated; or A represents a group of the formula ##STR2## wherein R.sub.2 is a hydrogen atom or a phenyl, C.sub.1-4 alkyl or C.sub.1-4 alkoxycarbonyl group, and their salts which have cytoprotective and antiulcer to activities. A process is also described for the preparation of said compounds.
