NEW AMMONIUM DERIVATIVES, A PROCESS FOR THEIR PREPARATION AND PHARMACEUTICAL COMPOSITIONS CONTAINING THEM
The présent invention relates to new ammonium dérivatives, to a process for their préparation and to pharmaceutical compositions containing them.
The compounds of the présent invention are new and hâve very valuable pharmacological characteristics in the field of apoptosis and oncology.
Apoptosis, or programmed cell death, is a physiological process that is crucial for embryonic development and maintenance of tissue homeostasis.
Apoptotic-type cell death involves morphological changes such as condensation of the nucléus, DNA fragmentation and also biochemical phenomena such as the activation of caspases which cause damage to key structural components of the cell, so inducing its disassembly and death. Régulation of the process of apoptosis is complex and involves the activation or repression of several intracellular signalling pathways (Cory et al. Nature Review Cancer 2002. 2, 647-656).
Deregulation of apoptosis is involved in certain pathologies. Increased apoptosis is associated with neurodegenerative diseases such as Parkinson’s disease, Alzheimer’s disease and ischaemia. Converseiy, déficits in the implémentation of apoptosis play a significant rôle in the development of cancers and their chemoresistance, in auto-immune diseases, inflammatory diseases and viral infections. Accordingly, absence of apoptosis is one of the phenotypic signatures of cancer (Hanahan et al. Cell 2000, 100, 57-70).
The anti-apoptotic proteins of the Bcl-2 family are associated with numerous pathologies. The involvement of proteins of the Bcl-2 family is described in numerous types of cancer, such as colon cancer, breast cancer, small-cell lung cancer, non-small-cell lung cancer, bladder cancer, ovarian cancer, prostate cancer, chronic lymphoid leukaemîa, lymphoma, myeloma, acute myeloid leukemia. pancreatic cancer, etc. Overexpression of the antiapoptotic proteins of the Bcl-2 family is involved in tumorigenesis, in résistance to chemotherapy and in the clinical prognosis of patients affected by cancer. Notably, Mcl-l, an anti-apoptotic Bcl-2 family member, is overexpressed in varions types of cancer (Beroukhim et al. Nature 2010, 899-905). There is, therefore, a therapeutîc need for compounds that inhibit the anti-apoptotic activity of the proteins of the Bcl-2 family.
Recently, thienopyrimidine dérivatives hâve been described as potent Mcl-l inhibitors useful for the treatment of cancers (WO 2015/097 i 23).
The présent invention provides novel ammonium dérivatives that hâve pro-apoptotic properties making it possible to use them in pathologies involving a defect in apoptosis, 5 such as, for example, in the treatment of cancer and of immune and auto-immune diseases.
Moreover, the compounds of the présent invention hâve high solubility as well as remarkable and unexpected pharmacological effects which could lead to very interesting candidates for oncology.

PHARMACOLOGICAL STUDY
EXAMPLE A: Inhibition of Mcl-1 bv the fluorescence polarisation technique
The relative binding potency of each compound was determined via Fluorescence Polarisation (FP). The method utiiised a Fluorescein labelled ligand (Fluorescein-pAlaAhx-A-REIGAQLRRMADDLNAQY-OH; mw 2,765) which binds to the Mcl-1 protein (such that Mcl-1 corresponds to the UniProtKB® primary accession number: Q07820) leading to an increased anisotropy measured in milli-polarisation (mP) units using a reader. The addition of a compound which binds competitively to the same site as the ligand will resuit in a greater proportion of unbound ligand in the System indicated by a decrease in mP units.
An 11 point serial dilution of each compound was prepared in DMSO and 2 μΐ transferred into fiat bottomed, low binding, 384-well plate (final DMSO concentration 5 %). 38 μΙ of buffer (10 mM 4-(2-hydroxyethyl)-l-piperazineethanesulfonic acid [HEPES], 150 mM NaCl, 0.05 % Tween 20, pH 7.4), containing the Fluorescein labelled ligand (final concentration 1 nM) and Mcl-1 protein (final concentration 5 nM) was then added.
Assay plates were incubated -2 hours at room température before FP was measured on a Biomek Synergy2 reader (Ex. 528 nm, Em. 640 nm, Cut off 510 nm) and mP units calculated. The binding of increasing doses of test compound was expressed as a percentage réduction in mP compared to a window established between ‘5 % DMSO only’ and ‘100% inhibition* controls. Il-point dose response curves were plotted with XL-Fit software using a 4-Parameter Logistic Model (Sigmoidal Dose-Response Model) and the inhibitory concentrations that gave a 50 % réduction in mP (IC50) were determined. Results are presented in Table 1 below.
The results show that the compounds of the invention inhibit interaction between the Mcl-1 protein and the fluorescent peptide described hereinbefore.
EXAMPLE B: /» vitro cvtotoxicitv
The cytotoxicity studies were carried out on the H929 multiple myeloma tumour line.
The cells are distrîbuted onto microplates and exposed to the test compounds for 48 hours.
The cell viability is then quantified by a colorimétrie assay, the Microculture Tétrazolium Assay (Carmichael et al. Cancer Res. 1987, 47, 936-942).
The results are expressed in IC50 (the concentration of compound that inhibits cell viability by 50 %) and are presented in Table l below.
The results show that the compounds of the invention are cytotoxic.

EXAMPLE C: Quantification of the cleaved form of PARP in vivo
The ability of the compounds of the invention to induce apoptosis, by measurîng cleaved PARP levels, is evaluated in a xenograft model of AMO-l multiple myeloma cells.
5.106 AMO-l cells are grafted sub-cutaneously into immunosuppressed mice (SCID 5 strain). 12 to 14 days after the graft, the animais are treated by intraveinous routes with the varions compounds. After treatment. the tumour masses are recovered and lysed, and the cleaved form of PARP is quantified in the tumour lysâtes.
