The present invention relates to a new cinnamoyl-cinnamic acid derivative selected from the group constituted by: (i) the m-cinnamoyl-cinnamic acid derivatives of formula ##STR1## in which: X.sub.o,X.sub.1,X.sub.2,X.sub.3,X.sub.4, which are identical or different, each represent an atom of hydrogen, a halogen, a lower alkyl group, a lower alkoxy group, the group NRR' (where R and R' identical or different, each represent an atom of hydrogen or a lower alkyl group), the group NO.sub.2, CF.sub.3 or OH; R.sub.1 represents an atom of hydrogen or a lower alkyl group; R.sub.2 represents an atom of hydrogen or the methyl group; Y represents a group OH, OR.sub.3 (where R.sub.3 is a lower alkyl group), NRR' (where R and R' are defined as hereinabove) or the group O(CH.sub.2).sub.n NR.sub.4 R.sub.5 (where n is an integer of value 1 to 5--and preferably 2 or 3)--; and R.sub.4 and R.sub.5, identical or different, each represent an atom of hydrogen, a lower alkyl group and may form with the nitrogen atom to which they are bonded a heterocyclic group of 5 to 7 vertices capable of being substituted and of comprising one or more other heteroatoms such as N and O); (ii) their geometrical isomers; and (iii) their salts. It also relates to its method of preparation and its use as pharmaceutical.
