Patent ID: 7547729

Claim:
A compound derived from substituted 1,3-diphenylprop-2-en-1-one represented by general formula (I) below: in which X 7 represents a group corresponding to the following formula: G 7 -R 7 in which G 7 is an oxygen or sulfur atom and R 7 is an alkyl chain substitued by a substituent from group 1 or a substituent from group 2, optionally R 7 can also be substituted by an aryl group, the substituents from group 1 are selected in the group consisting of carboxy groups having the formula: —COOR a , carbamoyl groups having the formula: —CONR b R c or the tetrazolyl group, the substituents from group 2 are selected in the group consisting of sulfonic acid (—SO 3 H) and sulfonamide groups having the formula: —SO 2 NR b R c , with R a , R b and R c , which are the same or different, representing a hydrogen atom or an alkyl group substituted or not, X 2 , X 4 , X 6 and X 8 , which are the same or different, represents alkyl groups, X 1 and X 5 are hydrogen atoms; X 3 represents a halogen atom or a thionitroso group or correspond to the formula (G 3 -R 3 ) n G′ 3 -R′ 3 in which: n can have the values 0 or 1 G 3 and G′ 3 , which are the same or different, represent a single bond, an oxygen atom or a sulfur atom, R 3 and R′ 3 , which are the same or different, represent an alkyl, alkenyl, aryl or heterocycle group, R′ 3 can also represent a hydrogen atom, X 3 not representing a heterocycle bound directly to the aromatic ring of the 1,3-diphenyl prop-2-en-1-one.
