Cinnamoyl-cinnamic acid derivative, its preparation and its use as a therapeutic agent

Abstract

Abstract 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 <IMAGE> (I) in which: Xo,X1,X2,X3,X4, 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 NO2, CF3 or OH; R1 represents an atom of hydrogen or a lower alkyl group; R2 represents an atom of hydrogen or the methyl group; Y represents a group OH, OR3(where R3 is a lower alkyl group), NRR' (where R and R' are defined as hereinabove) or the group O(CH2)nNR4R5(where n is an integer of value 1 to 5-and preferably 2 or 3)-; and R4 and R5, 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.
