Definitions
- the present invention relates to cancer therapy and relates to new anticancer agents having a specific mechanism of action. It also relates to a selection of chemical compounds as well as their therapeutic application in humans.
- the present invention relates to the use of new non-nucleotide chemical compounds which interact with specific structures of deoxyribonucleic acid (DNA) or ribonucleic acid (RNA).
- DNA deoxyribonucleic acid
- RNA ribonucleic acid
- These new compounds consist of a distributing agent linked to two nitrogen heteroaromatic groups, at least one of the nitrogen atoms of which is in quaternized form. They are particularly useful for very selectively stabilizing DNA folded into G-quadruplex structure (tetrads of guanines), as well when the G-quadruplex is formed by one, two or four strands of DNA.
- These new compounds are useful in the treatment of cancers and act in particular as telomerase inhibiting agents.
- telomerase inhibition via the stabilization of these G-quadruplexes can either be the arrest of cell mitosis and the death of rapidly dividing cells within one to a few weeks by a deprotection mechanism telomeric DNA, the induction of cancer cell senescence, as a result of the progressive shortening of telomeric DNA (Oncogene 2002, 21, 553-63; Oncogene 2002, 21, 592-97).
- Another therapeutic application, in the treatment of cancer, of the stabilization of DNA structures in G-quadruplex can be done by the inactivation of the promoter regions, rich in repetitions of guanines, oncogenes such as c-myc (J Biol. Chem. 2001, 276, 4640-46; Proc.
- Another therapeutic application, in the treatment of cancer, of the stabilization of DNA structures in G-quadruplexes can be the inhibition of helicases specific for DNA structures in G-quadruplexes, involved in mitosis. These helicases are also directly involved in various genetic diseases such as Bloom's syndromes (Cell 1995, 83, 655-66), Werner (Science 1996, 272, 258-62), Rothmund-Thomson (Nature Genetics 1999, 22, 82-4) or ataxia telangiectaxis.
- the compounds of the present invention have in particular the advantage from the therapeutic point of view of blocking telomerase.
- telomerase makes it possible to add repeated DNA sequences of the TTAGGG type, called telomeric sequences, at the end of the telomer, during cell division.
- telomerase makes the cell immortal. Indeed, in the absence of this enzymatic activity, the cell loses 100 to 150 bases per division, which makes it quickly senescent.
- telomeres maintained at a stable length during cell division.
- the telomerase was highly activated and that it allowed the addition of repeated motifs of telomeric sequences at the end of the telomer and therefore allowed the conservation of the length of the telomer. It has been shown for some time that more than 85% of cancer cells have positive tests for the presence of telomerase while somatic cells do not have this characteristic.
- telomerase is thus a highly wished target for treating cancer cells.
- the first obvious approach to blocking telomerase was the use of nucleotide structures (Proc. Natl. Acad. Sci. USA 1996, 93, 2635-39). Since then, various approaches have been developed to inhibit telomerase (Curr. Pharm. Des. 2002, 8, 2491-504). Among these approaches, the development of DNA ligands in G-quadruplexes is arousing growing interest (Mini Rev. Med. Chem. 2003, 3, 11-21).
- telomestatin a molecule capable of binding to a G-quadruplex DNA structure, in a very selective manner compared to a double stranded DNA (J. Amer. Chem. Soc. 2001, 123, 1262-1263).
- a highly selective DNA molecule in G-quadruplex will have the double advantage of targeting DNA structures in G-quadruplex while avoiding undesirable mechanisms of toxicity linked to non-selective attachment to the genome.
- WO 0296903 describes the preparation of heterocyclic diamides of general formula (I) below, as DNA ligands in G-quadruplex and their use as telomerase inhibitors: (I) nitrogen aromatic cycle - (NR 3 ) p - (CO) n- distributor - (CO) m - (NR ' 3 ) q - aromatic or non-aromatic cycle with n, m, p and q identical or different represent l 'integer 0 or 1, in which

- Step 1 The operation is carried out as in step 3 of Example 2, but starting from 140 mg of 2,6-pyridine-dicarboxylic-2 - [(quinolin-6-yl) amide], obtained with 1 step 1 of Example 9, 73 ⁇ L of 1- (2-aminoethyl) piperidine, 100 mg of EDCI and 7 mg of HOBT in 5 ml of dichloromethane and 5 ml of DMF for 48 hours at temperature room.
- Step 2 The procedure is as in step 2 of Example 1, but starting with 200 mg of 2,6-pyridine-dicarboxylic acid-2 - [(quinolin-6-yl) amide] -6- [ 2- (piperidin-1-yl) -ethylamide], obtained above, in 2 ml of DMF and 6 ml of iodomethane.
- Step 1 The procedure is as in step 1 of Example 1, but starting from 502 mg of 4-bromo-2,6-pyridine-dicarboxylic acid, which can be prepared according to Tetrahedron lett. 2001, 42, 4849-51, and 588 mg of 3-aminoquinoline, which can be prepared according to Tetrahedron. Lett. 2001, 42, 3251-54, 821 mg of EDCI and 55 mg of HOBT in 23 ml of DMF with stirring for 20 hours at room temperature. 935 mg of 4-bromo-2,6-pyridine-dicarboxylic acid-bis - [(quinolin-3-yl) amide] is obtained in the form of a gray-green powder, used as it is in the following step .
- Step 2 The procedure is as in step 2 of Example 1, but starting with 300 mg of 4-bromo-2,6-pyridine-dicarboxylic-bis - [(quinolin-3-yl) amide] acid] , obtained above in 8 mL of DMF and 12.63 mL of iodomethane. Then obtained after recrystallization from ethanol, 296 mg of diodide of 4-bromo-2,6-pyridine-dicarboxylic acid-bis - [(1-methyl-quinolinio-3-yl) amide], in the form d '' a yellow solid with the following characteristics:
