Patent ID: 7999101

Claim:
A compound of formula (I): wherein E is a 2,4,6-substituted 1,3,5-triazine; R1 and R2, being identical or different, but never simultaneously equal to H, are selected from the group consisting of: H, —R7-NH 2 , —CH 2 —NH—NH 2 , and a linear or branched alkyl with from 1 to 10 carbon atoms, or, R1 and R2, together with the nitrogen atom to which they are bound, form a 5 or 6 member heterocyclic ring or morpholine; R7 is selected from the group consisting of: a linear or branched alkyl with from 2 to 10 carbon atoms; a linear or branched alkenyl, with from 3 to 10 carbon atoms and from 1 to 5 double bonds; an aryl; and a (C 1 -C 20 ) alkyl-aryl-(C 0 -C 20 ) alkyl; R3 and R4, being identical or different, but never simultaneously equal to H, are selected from the group consisting of: H, —R8-SH, —R8-NH—NH 2 , —R8-CO—R9, and —R8-NH 2 , R8 is selected from the group consisting of: a linear or branched alkyl with from 2 to 10 carbon atoms; a linear or branched alkenyl, with from 3 to 10 carbon atoms and from 1 to 5 double bonds; an aryl; and a (C 1 -C 20 ) alkyl-aryl-(C 0 -C 20 ) alkyl; R9 is selected from the group consisting of: H and a linear or branched alkyl with from 1 to 10 carbon atoms; R5 and R6, being identical or different, but never simultaneously equal to H, are selected from the group consisting of: H, a linear or branched alkyl with from 6 to 20 carbon atoms, a linear or branched alkenyl with from 6 to 20 carbon atoms and with from 1 to 10 double bonds, and a (C 1 -C 20 ) alkylaryl.
