- the compounds of formula I are potent antagonists of FGF-1 and 2
- Their ability to inhibit both the formation of new vessels from differentiated endothelial cells and to block the differentiation of adult human bone marrow cells CD34 + CD133 + in endothelial cells has been demonstrated in vitro.
- their ability to inhibit pathological angiogenesis has been demonstrated in vivo.
- the compounds of formula I have been shown to be potent antagonists of the FGF-1 receptor.
- FGFs are significantly involved via autocrine, paracrine or juxtacrine secretions in the phenomena of deregulation of the stimulation of cancer cell growth.
- FGFs affect tumor angiogenesis which plays a major role both in the growth of the tumor but also in the phenomena of metastasization.
- Angiogenesis is a process of generation of new capillary vessels from preexisting vessels or by mobilization and differentiation of bone marrow cells.
- endothelial cells an uncontrolled proliferation of endothelial cells and a mobilization of angioblasts from the bone marrow are observed in the neovascularization processes of tumors.
- growth factors have been shown in vitro and in vivo to stimulate endothelial proliferation, including FGF-1 or a-FGF and FGF-2 or b-FGF. These two factors induce the proliferation, migration and production of proteases by endothelial cells in culture and neovascularization in vivo.
- a-FGF and b-FGF receptors interact with endothelial cells via two classes of receptors, high affinity tyrosine kinase receptors (FGFs) and low affinity heparan sulfate proteoglycan receptors (HSPGs). located on the surface of cells and in extracellular matrices. While the paracrine role of these two factors on endothelial cells is widely described, a-FGF and b-
- a-FGF and b-FGF and their receptors represent very relevant targets for therapies aimed at inhibiting angiogenesis processes (Keshet E, Ben-Sasson SA.,. J. Clin. Invest, (1999), vol 501, ppl04-1497; Presta M, Rusnati M, Dell'Era P, Tanghetti E, Urbinati C, Giuliani R et al, New York: Plénum Publishers, (2000), pp7- 34, Billottet C, Janji B, Thiery JP, Jouanneau J, Oncogene, (2002) vol 21, pp8128- 8139).
- A-FGF and b-FGF play an important role in the growth and maintenance of prostate cells. It has been shown in both animal and human models that an alteration of the cellular response to these factors plays a key role in the progression of prostate cancer. Indeed, in these pathologies, there is both an increase in the production of a-FGF and b-FGF by fibroblasts and endothelial cells present at the level of the tumor and an increase in the expression of FGF receptors on tumor cells. . Thus paracrine stimulation of prostate cancer cells takes place, and this process would be a major component of this pathology.

- Glioma cells produce in vitro and in vivo a-FGF and b-FGF and have different FGF receptors on their surface. This therefore suggests that these two factors, through an autocrine and paracrine effect, play a pivotal role in the progression of this type of tumor. In addition, like most solid tumors, the progression of gliomas and their ability to induce metastases is very dependent on the angiogenic processes in the primary tumor. FGF-1 receptor antisense has also been shown to block the proliferation of human astrocytomas. In addition, naphthalenesulfonate derivatives are described to inhibit the cellular effects of a-FGF and b-FGF in vitro and the angiogenesis induced by these growth factors in vivo.
- a compound possessing an antagonist activity of a-FGF and / or b-FGF and / or FGF receptors can represent a therapy of choice in these pathologies (Yamada SM, Yamaguchi F, Brown R , Berger MS, Morrison RS, Glia, (1999), vol 76, pp28-66; Auguste P, Gt ⁇ rsel DB, Lemière S, Reimers D, Cuevas P, Carceller F et al., Cancer Res., (2001), vol 26, pp 61-1717).
- b-FGF has been detected in many lymphoblastic and hematopoietic tumor cell lines. FGF receptors are also present on the majority of these lines, suggesting a possible autocrine cellular effect of a-FGF and b-FGF inducing the proliferation of these cells. Furthermore, it has been reported that angiogenesis of the bone marrow by paracrine effects was correlated with the progression of some of these pathologies. More specifically, it has been shown in CLL (chronic lymphocytic leukemia) cells that b-FGF induces an increase in the expression of anti apoptotic protein (Bcl2) leading to an increase in the survival of these cells and therefore participates in important way to their cancerization.

- vascular coarctation myocardial infarction
- various vascular disorders morphological, molecular and functional changes such as hypertrophy of cardiac myocytes, accumulation of matrix proteins and re-expression of fetal genes.
- B-FGF is involved in this pathology. Indeed, the addition of b-FGF to cultures of cardiomyocytes of newborn rats modifies the profile of the genes corresponding to the contractile proteins leading to a profile of fetal type genes. In addition, adult rat myocytes show a hypertrophic response under the effect of b-FGF, this response being blocked by neutralizing anti-b-FGF antibodies.
- vascular disorders due to diabetes are characterized by impaired vascular reactivity and blood flow, hyperpermeability, response proliferative exacerbated and increased deposition of matrix proteins. 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.

- IBD inflammatory bowel disease
- UC ulcerative colitis
- CD Crohn's disease
- IBDs are characterized by immune dysfunction resulting in the inappropriate production of inflammatory cytokines inducing the establishment of a local microvascular system. This angiogenesis of inflammatory origin results in intestinal ischemia induced by vasoconstriction. Significant circulating and local levels of b-FGF have been measured in patients with these pathologies (Kanazawa S, Tsunoda T, Onuma E,
