- the process for preparing the compounds according to the invention uses mono-, di- or oligosaccharide-based basic synthons prepared as previously reported in the literature and chosen taking into account in particular the orthogonality of the protective groups.
- These synthons are then coupled to each other so as to provide a fully protected equivalent of a compound according to the invention.
- This protected equivalent is then converted to a compound according to the invention using methods well known to those skilled in the art.
- the compounds of the invention additionally containing an azasugar (or substituted piperidine) unit, their synthesis requires the preparation of a precursor of this unit bearing protective groups compatible with the subsequent couplings to mono-, di-, or oligosaccharides.

- the activity of heparanase is evidenced by its ability to degrade fondaparinux.
- the concentration of fondaparinux is determined by its anti-factor Xa activity.
- Heparanase is produced by Sanofi-Synthélabo (Labège, France).
- heparanase inhibitor varying dilutions: from 1 nM to 10 ⁇ M
- a fixed concentration of heparanase for each batch, preliminary experiments make it possible to determine the enzymatic activity sufficient for the degradation of 0.45 ⁇ g / ml of fondaparinux added.
- the mixture is brought into the presence of fondaparinux and left for 1 hour at 37 ° C.
- the reaction is stopped by heating at 95 ° C. for 5 minutes.
- the residual fondaparinux concentration is finally measured by addition of factor Xa and its specific chromogenic substrate (Ref S2222).
- the anti-factor Xa activity of fondaparinux is measured in the following way:
- 100 ⁇ l of the solution obtained in step a) are mixed with 100 ⁇ l of AT (0.5 ⁇ / ml). It is maintained for 2 minutes at 37 ° C. and 100 ⁇ l of factor Xa (7 nkat / ml) are then added. It is maintained for 2 minutes at 37 ° C. and then 100 ⁇ l of chromogenic substrate (Ref .: S2222) (1 mM) are added. It is maintained for 2 minutes at 37 ° C. and then 100 ⁇ l of acetic acid (50%) are added. The reading of the optical density is carried out at 405 nm.
- the compounds according to the present invention have Cl 50 values of between 10 nM and 10 ⁇ M.

- the HT1080 invasion measurements are carried out on Becton Dickinson falcon HTS Fluoroblok Multiwell Insert System Kit in 24-well plates (Ref: 351 158). These measurement chambers provide the cells with conditions for evaluating their invasive properties in vitro.
- the kit consists of a plate associated with culture inserts containing a 8 micron pore-filled PET membrane on which a uniform layer of Matrigel Matrix (Becton Dickinson, P / N 354230) is deposited.
- Matrigel is a soluble basement membrane extracted from the EHS tumor (Engelbreth-Holm-Swarm) which, thanks to its composition, solidifies a structure equivalent to a basement membrane.
- the Matrigel layer occludes the pores of the membrane, thus blocking the migration of non-invasive cells through the membrane.
- Invasive cells (tumor or non-tumor) will be able to detach and invade the Matrigel layer before migrating through the membrane.
- Quantification of cell migration is performed by calcein labeling AM (Molecular Probes C-3100).
- the fluorescent signal emitted is measured using a Perkin Elmer Wallac VICTOR 3 reader and can be directly correlated with the number of cells invading the Matrigel gel. By comparing them with controls carried out in the same experiment as the products studied (response in the presence of 0% and 5% fetal calf serum), it is possible to determine a percentage inhibition of the cellular invasion in the presence of products.
- a series of independent determinations (ranging from 2 to 4) made it possible to show that at a concentration of between 1 nM and 10 ⁇ M, the compounds according to the invention inhibit, on average, the cellular invasion with a percentage of between 8 and 60. %.
- compound No. 20 inhibits cell invasion by 53 ⁇ 11%.
- the compounds of formula (I) according to the present invention thus have a good affinity for heparanases and exhibit an inhibitory effect of heparanases.
- Tumor biopsies revealed the same correlation (Vlodavsky et al., Isr. J. Med. ScL, (1988), Vol. 24 (9-10), p.464-470). There is therefore a correlation between the increased heparanase secretion and the metastatic potential of tumor cells (Vlodavsky et al., Invasion Matastasis, (1994), Vol.14, p.290-302, Nature Medicine, (1999) Vol.5: 793-802).
- ECM Heparanases, secreted by tumor cells, degrade HSPGs and HS, major components of ECM. ECM thus perforated, circulates the tumor cells and metastatic and also allows the invasion of neoformed blood vessels (angiogenesis) (Suzanne A. Eccles, Nat. Med., (1999), Vol.5 (7), p.793 -809).
- Angiogenesis is a process of generating new capillaries from preexisting vessels or by mobilizing and differentiating bone marrow cells. Thus, both uncontrolled proliferation of endothelial cells and mobilization of angioblasts from the bone marrow are observed in neovascularization processes of tumors.
- cancer or carcinoma
- metastatic tumor cells such as melanomas, mesothelioma, lymphoma, leukemia, fibrosarcoma, rhabdomyosarcoma, mastocytoma, but also carcinomas affecting a tissue such as the colon, rectum, prostate, lungs, breasts, pancreas, intestine, kidneys, ovaries, uterus, cervix uterus, bladder, liver and stomach.
- Carcinomas infiltrate adjacent tissues and spread (metastasize) to other distant organs, eg, liver, lungs, brain or bones.
- a compound having heparanase inhibitory activity such as the compounds of the invention may therefore be useful for the treatment of such cancers (Fang J et al., Proc Natl Acad Sci USA, (2000), Vol.97 (8), pp. 3884-3889, Kondraganti et al., Cancer Res., (2000), Vol.60 (24), pp. 6851-6855), and in particular colorectal cancer, prostate cancer, lung cancer, breast, pancreas, kidney, bladder and ovaries.
- the p75 receptor a receptor for neurotrophin family (NT) molecules
- NT neurotrophin family
- a compound such as the compounds of the invention possessing a heparanase inhibitory activity, may therefore be useful for the treatment of inflammatory diseases, especially inflammatory chronic diseases such as rheumatoid arthritis or IBD (Inflammatory Bowel Disease), consisting of two forms of inflammatory bowel disease: UC (ulcerative colitis) and
- CD Crohn's
- a compound, a heparanase inhibitor, according to the invention can present a therapy of choice in these pathologies.
- heparanases are known to be involved in some cases of renal failure where renal filtration and reabsorption functions may be impaired (FASEB J, (2004), Vol.18, pp. 252-263).
- a compound, a heparanase inhibitor, according to the invention may present a therapy of choice in such pathologies.
- ECM HSPGs also appear to play a role as major regulators of cell growth and activation via modulation of growth factors, in particular FGFs (Fibroblast Growth Factors).
- FGFs Fibroblast Growth Factors
- the activity of heparanases involves the release of growth factors such as FGFs, which in particular stimulate angiogenesis and promote tumor progression (Bashkin et al., Biochemistry, (1989), Vol.28, p. 1743).
- FGFs Fibroblast Growth Factors
- heparanases represent relevant targets for the treatment of diseases in which FGFs are involved.
- FGFs are significantly involved via autocrine, paracrine or juxtacrine secretions in the phenomena of deregulation of the stimulation of the growth of cancer cells.
- FGFs initiate tumor angiogenesis, which plays a major role in both tumor growth and metastasizing phenomena.
- Angiogenesis is a process of generating new capillaries from preexisting vessels or by mobilizing and differentiating bone marrow cells.
- endothelial cells and mobilization of angioblasts from the bone marrow are observed in neovascularization processes of tumors. It has been shown in vitro and in vivo that several growth factors stimulate endothelial proliferation, and in particular FGF-1 or ⁇ -FGF and FGF-2 or b-FGF.
- ⁇ -FGF and ⁇ -FGF play an important role in the growth and maintenance of prostate cells (DoII JA et al., Prostate, (2001), Vol.305, p.49-293.
- Several studies show the presence of ⁇ -FGF and ⁇ -FGF and their FGFR receptors in both human breast tumor lines (including MCF7) and in tumor biopsies.
- Glioma cells produce in vitro and in vivo a-FGF and b-FGF and have different FGF receptors on their surface.
- CML chronic myelomonocytic leukemia
- Proliferation and migration of vascular smooth muscle cells contribute to intimal hypertrophy of the arteries and thus play a prominent role in atherosclerosis and restenosis after angioplasty and endoarterectomy.
- In vivo studies show, after carotid injury by "balloon injury", local production of ⁇ -FGF and b-FGF.
- vascular disorders due to diabetes are characterized by impaired vascular reactivity and blood flow, hyperpermeability, exacerbated proliferative response, and increased matrix protein deposition. More specifically, a-FGF and b-FGF are present in the pre-retinal membranes of patients with diabetic retinopathies, in the membranes of the underlying capillaries and in the vitreous humor of patients suffering from proliferative retinopathies.
- Rheumatoid arthritis is a chronic disease with an unknown etiology. While it affects many organs, the most severe form of RA is synovial inflammation of the progressive joints leading to destruction. Angiogenesis seems to significantly affect the progression of this pathology. Thus, ⁇ -FGF and b-FGF were detected in the synovial tissue and in the joint fluid of RA patients, indicating that this growth factor is involved in the initiation and / or progression of this pathology. In AIA (adjuvant-induced model of arthritis) models in rats, over-expression of b-FGF has been shown to increase the severity of the disease. that an anti-b-FGF neutralizing antibody blocks the progression of RA (Yamashita et al., J. Immunol., (2002), Vol.57, pp. 168-450, Manabe et al., Rheumatol, (1999) Vol.20: 38-714).
