Abstract: Endometriosis is a chronic inflammatory systemic sex hormone-dependent gynecological disease, characterized by the presence and growth of endometrial tissue (glands and stroma) outside the uterine cavity, predominantly, but not exclusively, in the pelvic compartment. Here, the inventors show that the use of Neuropilin/VEGF binding inhibitors, so called, Neuropilin antagonist (NRPa), bring new perspective to treat and cure endometriosis in women suffering thereof. NRPa alone is efficient to inhibit primary endometrial cell proliferation and apoptosis/necrosis program cell death of targeted cells. The effective NRPa concentration needed is very low (NRPa-48 IC50=10?7M) and is dependent of the NRPa structure. Moreover, the association of NRPa with progestogen drug increases the anti-proliferative effect. Therefore, the present invention relates to the use of neuropilin antagonists for the treatment of endometriosis.

Abstract: Neuropilin-1 is henceforth a relevant target in cancer treatment, however way-of-action is remains partly elusive and the development of small inhibitory molecules is therefore required for its study. Here, the inventors report that two neuropilin small-sized antagonists (NRPa-47, NRPa-48), VEGF-A165/NRP-1 binding inhibitors, are able to decrease VEGF-Rs phosphorylation and to modulate their downstream cascades in triple negative breast cancer cell line (MDA-MB-231). In particular, the inventors showed for the first time, how NRPa may altered tumor cell signaling and contributed in the down-modulation of the cancer therapeutic key factor p38?-kinase phosphorylation. More importantly, the association of NRPa with a p38? inhibitor leads to additional and/or synergistic effect of these drugs (depending of the dose used) for significantly reducing breast cancer cell proliferation Thus, the efficient association of NRPa and p38?-kinase inhibitors are thus credible for the treatment of cancer.
