Definitions
- the present invention relates to cancer therapy and relates to new anticancer agents having a very specific mechanism of action. It also relates to new 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). These new compounds consist of a distributing agent linked to an aminoaromatic group. These new compounds are useful in the treatment of cancer and act in particular as telomerase inhibiting agents. They are particularly useful for stabilizing DNA in a G-quadruplex structure (guanine tetrads).
- the therapeutic application of telomerase inhibition via the stabilization of these G-quadruplexes is the arrest of cell mitosis and the death of rapidly dividing cells such as cancer cells and possibly the induction of cell senescence cancerous.
- telomeres have the therapeutic advantage of blocking telomerase.
- telomerase makes it possible to add repeated DNA sequences of the T T A G G type, called telomeric sequences, at the end of the telomer, during cell division.
- telomerase makes the cell immortal. In fact, in the absence of this enzymatic activity, the cell loses 100 to 150 bases each division, which makes it rapidly sinking. When rapidly dividing cancer cells appeared, these cells appeared to have telomeres maintained at a stable length during cell division.
- telomerase was highly activated and that it allowed the addition of repeating motifs of telomeric sequences at the end of the telomer and therefore allowed the conservation of the length of the telomer in cancer cells. It has appeared for some time that more than
