Abstract: The present invention relates to novel bis-hydrazone derivatives of formula (I): wherein Ar1 and Ar2 may be identical or different and are each independently selected from the group consisting of groups of formula (II) and (III): Y1 and Z1 are independently CH or NRc+, provided that al least one of Y1 and Z1 is NRc+ and at least one of Y1 and Z1 is CH, and Ra, Rb, Rc, X2? and L as defined in the claims, or a hydrate or a solvate thereof. Compositions and kits comprising same are also described. Said bis-hydrazone derivatives of formula (I), compositions and kits are useful as drugs, in particular for treating or preventing cancers associated with the Epstein-Barr Virus.

Abstract: Triphenylamine derivatives useful as fluorophores in biology, in particular for two-photon microscopy; and compositions comprising these derivatives, to the use of these compositions and of the derivatives themselves for labelling biological molecules (or “biomolecules”) such as nucleic acids, oligonucleotides, proteins, polypeptides, plasmids, and the like, for their examination in particular by two-photon microscopy, and to biomolecules labelled with the said derivatives.

Abstract: The present invention relates to Penta-hexa-, hepta-, octa-, nona- and, deca-heteroaryl derivatives, comprising a combination of heterocycle 1 (Het-1)a and/or heterocycle 2 (Het-2)b and/or heterocycle 3 (Het-3)c and/or heterocycle 4 (Het-4)d of formulae I, II, III and IV respectively, the N-oxides, the pharmaceutically acceptable addition salts. The compounds claimed are suitable for the treatment of cancer.

Abstract: The invention concerns the use of aromatic compounds capable of binding with G-quadruplex structures to produce medicines with anti-telomerase effect. Said compounds correspond to formula (I) wherein: R1, R2 and R3, identical or different, represent a hydrogen atom, or a —CH2—NH—(CH2)n—X group, wherein n is an integer from 2 to 4, and X is selected among —NH2—, —N(CH3)2 radicals, a heterocyclic radical such as piperidyl, imidazolyl, morpholinyl radical, or an indole-type condensed heterocyclic radical, —Z represents CH or N, each compound comprising two nitrogen atoms in the Z positions. The invention is useful for producing anticancer medicines.
