  • Tumor invasion processes are the main cause of death in cancer patients.
  • tumor cells not only have a strong ability to proliferate, but also a strong ability to destroy tissue and infiltrate into nearby tissues, including blood vessels and lymphatics, then to migrate through the bloodstream or lymphatic circulation to tissues located at parts of the body far removed from the primary tumor.
  • tumor cells have the ability to circulate and then form secondary tumors, also called metastases, in tissues distant from the primary tumor.
  • metastases is a multi-stage physiological phenomenon, in which tumor cells break away from the primary tumor, invade the extracellular matrix, enter through the blood vessels, enter the vasculature by intravasation, and then stop migration into the blood or lymphatic circulation at a distant site, extravasate out of the circulation, then attach to a distant tissue and proliferate to form a secondary tumor.
  • epithelium is the most abundant tissue type in the human or animal body. This is probably one of the reasons why more than 90% of human cancers originate from the malignant transformation of epithelial cells.

Description

Utilisation d'inhibiteurs d'aminopeptidase ou de composés azaindole pour la prévention ou le traitement de métastases cancéreuses d'origine épithéliale Use of aminopeptidase inhibitors or azaindole compounds for the prevention or treatment of cancer metastases of epithelial origin
Domaine de l'inventionField of the invention
La présente invention se rapporte au domaine du traitement thérapeutique des cancers, et plus particulièrement à la prévention ou au traitement des métastases, dans le cas de cancer chez l'homme ou l'animal.The present invention relates to the field of therapeutic treatment of cancers, and more particularly to the prevention or treatment of metastases, in the case of cancer in humans or animals.
Art antérieurPrior art
De manière générale, environ 35% des patients nouvellement diagnostiqués comme étant affectés d'un cancer sont exempts de métastases. Ces patients peuvent être guéris par des traitements locaux dirigés contre la tumeur, tels que la chirurgie ou l'exposition à certains rayonnements. L'autre partie des patients nouvellement diagnostiqués comprend (i) les patients ayant déjà des métastases détectables (30% des patients) et (ii) les patients n'ayant pas de métastases détectables au moment du diagnostic (35% des patients). Le traitement de cette autre partie des patients est en général un traitement systémique incluant, par exemple, l'administration de médicaments chimio-thérapeutiques qui interfèrent avec la croissance des cellules cancéreuses.In general, approximately 35% of patients newly diagnosed with cancer are free of metastases. These patients can be cured by local treatments directed against the tumor, such as surgery or exposure to certain radiation. The other part of newly diagnosed patients includes (i) patients already having detectable metastases (30% of patients) and (ii) patients with no detectable metastases at the time of diagnosis (35% of patients). The treatment of this other part of the patients is generally a systemic treatment including, for example, the administration of chemotherapeutic drugs that interfere with the growth of the cancer cells.
Les processus d'invasion tumorale constituent la cause essentielle de la mortalité chez les patients affectés d'un cancer.Tumor invasion processes are the main cause of death in cancer patients.
On sait que, dans certains cancers, les cellules tumorales ont non seulement une forte capacité à proliférer, mais aussi une forte capacité à détruire les tissus et à s'infiltrer dans les tissus voisins, y compris dans les vaisseaux sanguins et les vaisseaux lymphatiques, puis à migrer par la circulation sanguine ou la circulation lymphatiquevers des tissus localisés à des endroits du corps très éloignés de la tumeur primaire. Ainsi, dans certains cancers, les cellules tumorales ont la capacité de circuler puis de former des tumeurs secondaires, aussi appelées métastases, dans des tissus distants de la tumeur primaire.It is known that, in some cancers, tumor cells not only have a strong ability to proliferate, but also a strong ability to destroy tissue and infiltrate into nearby tissues, including blood vessels and lymphatics, then to migrate through the bloodstream or lymphatic circulation to tissues located at parts of the body far removed from the primary tumor. Thus, in some cancers, tumor cells have the ability to circulate and then form secondary tumors, also called metastases, in tissues distant from the primary tumor.
La formation de métastases est un phénomène physiologique à étapes multiples, au cours duquel des cellules tumorales se détachent de la tumeur primaire, envahissent la matrice extra-cellulaire, pénètrent au travers des vaisseaux sanguins, entrent dans le système vasculaire par intravasation, puis arrêtent leur migration dans la circulation sanguine ou lymphatique à un site distant, sortent de la circulation par extravasation, puis se fixent dans un tissu distant et prolifèrent pour former une tumeur secondaire.The formation of metastases is a multi-stage physiological phenomenon, in which tumor cells break away from the primary tumor, invade the extracellular matrix, enter through the blood vessels, enter the vasculature by intravasation, and then stop migration into the blood or lymphatic circulation at a distant site, extravasate out of the circulation, then attach to a distant tissue and proliferate to form a secondary tumor.
Par ailleurs, l'épithélium représente le type de tissu le plus abondant dans l'organisme humain ou animal. C'est sans doute l'une des raisons pour lesquelles plus de 90% des cancers chez l'homme ont pour origine la transformation maligne de cellules épithéliales. En particulier, le cancer épithélial de type colo-rectal constitue la deuxième cause de mortalité par cancer dans les pays industrialisés.In addition, the epithelium is the most abundant tissue type in the human or animal body. This is probably one of the reasons why more than 90% of human cancers originate from the malignant transformation of epithelial cells. In particular, colorectal epithelial cancer is the second leading cause of cancer death in industrialized countries.
Dans la plupart des cas de cancers, y compris pour les cancers épithéliaux, la mortalité n'est pas due à la tumeur primaire, mais aux métastases qui disséminent de manière systémique dans l'organisme, à partir de la tumeur primaire. Cette progression maligne qui conduit à l'invasion tumorale, qui se manifeste cliniquement par la génération de métastases, est conditionnée initialement par la perte d'adhésion cellulaire de certaines cellules tumorales ainsi que par une augmentation de la motilité cellulaire, ce qui entraîne que ces cellules tumorales invasives quittent le tissu de la tumeur primaire puis colonisent un ou plusieurs tissus cibles, parfois très distants du site de la tumeurs primaire, dans l'organisme humain ou animal. Dans les cancers épithéliaux, la progression maligne est accompagnée d'une perte des jonctions inter-cellulaires réalisées par la E-cadhérine, au niveau de la tumeur primitive.In most cases of cancer, including epithelial cancers, the mortality is not due to the primary tumor, but to metastases that spread systemically in the body, from the primary tumor. This malignant progression that leads to tumor invasion, which is clinically manifested by the generation of metastases, is initially conditioned by the loss of cellular adhesion of certain tumor cells as well as an increase in cell motility, which results in these Invasive tumor cells leave the tissue of the primary tumor and then colonize one or more target tissues, sometimes very distant from the site of the primary tumors, in the human or animal body. In epithelial cancers, the malignant progression is accompanied by a loss of inter-cellular junctions made by E-cadherin, at the level of the primary tumor.
Parmi les cancers épithéliaux, les cancers colo-rectaux représentent les seconds cancers les plus fréquents dans les pays industrialisés. L'évolution du cancer colo-rectal est une succession d'événements qui débute par une phase d'initiation due à une dérégulation génomique affectant les propriétés prolifératives des cellules. La seconde phase est une phase de progression tumorale qui conduit à des changements de morphologie cellulaire et à l'émergence de clones cellulaires transformés. Enfin, la dernière phase consiste en la phase d'invasion consécutive à la transition épithélio- mésenchymateuse, transition définie comme la capacité d'une cellule épithéliale à se séparer des cellules voisines et à migrer vers d'autres sites de l'organisme.Among epithelial cancers, colorectal cancers represent the second most common cancers in industrialized countries. The evolution of colorectal cancer is a succession of events that begins with an initiation phase due to a genomic dysregulation affecting the proliferative properties of cells. The second phase is a phase of tumor progression that leads to changes in cell morphology and the emergence of transformed cell clones. Finally, the last phase consists of the invasion phase following the epithelio-mesenchymal transition, defined as the ability of an epithelial cell to separate from neighboring cells and migrate to other sites in the body.
Dans la pratique, il a été montré que les traitements thérapeutiques anticancéreux systémiques ont peu d'effet sur les métastases, et en particulier sur les macro-métastases, qui résident dans des organes distants du site de la tumeur primaire, tels que le poumon, le foie, la moelle osseuse ou le cerveau. Ainsi, les patients cancéreux décèdent souvent du fait des cancers métastatiques provoqués par les métastases des cellules cancéreuses.In practice, it has been shown that systemic anti-cancer therapeutics have little effect on metastases, and particularly on macro-metastases, which reside in organs distant from the primary tumor site, such as the lung, the liver, bone marrow or brain. Thus, cancer patients often die due to metastatic cancers caused by metastases of cancer cells.
De plus, jusqu'à présent, la recherche de molécules anti-invasives a généralement été basée (i) soit sur la capacité des composés candidats à inhiber la croissance des cellules tumorales, (ii) soit sur l'aptitude des composés candidats à inhiber la migration des cellules. Mais, selon la première stratégie, les composés sélectionnés n'ont pas d'effet sur la dissémination des cellules invasives et donc pas d'effet sur le processus métastatique lui-même. Et, dans le second cas, les composés peuvent avoir une activité d'inhibition de la capacité des cellules à migrer dans l'organisme et à former des métastatses, mais n'ont pas d'effet sur les cellules métastatiques qui ont déjà migré.Moreover, until now, the search for anti-invasive molecules has generally been based on (i) the ability of candidate compounds to inhibit the growth of tumor cells, (ii) the ability of the candidate compounds to inhibit cell migration. But, according to the first strategy, the selected compounds have no effect on the spread of invasive cells and therefore no effect on the metastatic process itself. And, in the second case, the compounds may have an activity of inhibiting the ability of cells to migrate into the body and forming metastases, but have no effect on metastatic cells that have already migrated.
Il existe donc un besoin dans l'état de la technique pour l'identification de substances actives possédant la capacité de prévenir ou de traiter les métastases chez des patients affectés d'un cancer, afin d'accroître significativement les chances de guérison de ces patients.There is therefore a need in the state of the art for the identification of active substances having the ability to prevent or treat metastases at patients with cancer, to significantly increase the chances of recovery of these patients.

Description détaillée de l'inventionDetailed description of the invention
La présente invention fournit de nouveaux moyens pour prévenir ou traiter les métastases dans divers cancers, en particulier dans les cancers épithéliaux, y compris dans des cancers colo-rectaux, des cancers mammaires, des cancers du foie, des cancers du pancréas, des cancers de la prostate et des cancers de l'utérus.. De manière surprenante, il a été montré selon l'invention que des composés inhibiteurs d'aminopeptidase et des composés de la famille des azaindoles ont la capacité d'inhiber ou de bloquer les propriétés invasives de cellules cancéreuses initialement aptes à générer des métastases.The present invention provides novel means for preventing or treating metastasis in various cancers, particularly in epithelial cancers, including colorectal cancers, breast cancers, liver cancers, pancreatic cancers, Prostate and cancers of the uterus. Surprisingly, it has been shown according to the invention that aminopeptidase inhibiting compounds and compounds of the azaindole family have the ability to inhibit or block invasive properties. of cancer cells initially capable of generating metastases.
Plus précisément, il est montré selon l'invention que des composés inhibiteurs d'aminopeptidase et des composés de la famille des azaindoles ont la capacité d'inhiber ou de bloquer les propriétés de migration de cellules métastatiques originaires de divers cancers épithéliaux, tels que des cancers colo-rectaux ou bien encore des cancers mammaires.More specifically, it is shown according to the invention that aminopeptidase inhibiting compounds and compounds of the azaindole family have the capacity to inhibit or block the migration properties of metastatic cells originating from various epithelial cancers, such as colo-rectal cancers or breast cancers.
L'identification des propriétés anti-métastatiques de ces composés a permis au demandeur de mettre au point des compositions pharmaceutiques pour prévenir ou traiter les métastases cancéreuses chez l'homme ou l'animal, comprenant, à titre de principe actif au moins un composé choisi parmi un composé inhibiteur d'aminopeptidase et un composé azaindole. Cette identification de propriétés préventives ou thérapeutiques nouvelles a rendu possible l'utilisation de ces composés pour la fabrication de compositions pharmaceutiques à activité anti-métastatique. Ainsi, la présente invention est relative à un composé choisi parmi un composé inhibiteur d'aminopeptidase et un composé aza-indole pour la prévention ou le traitement de métastases cancéreuses chez l'homme ou l'animal.The identification of the anti-metastatic properties of these compounds has enabled the applicant to develop pharmaceutical compositions for preventing or treating cancer metastases in humans or animals, comprising as active ingredient at least one selected compound. from an aminopeptidase inhibitor compound and an azaindole compound. This identification of new preventive or therapeutic properties has made possible the use of these compounds for the manufacture of pharmaceutical compositions with anti-metastatic activity. Thus, the present invention relates to a compound selected from an aminopeptidase inhibiting compound and an aza-indole compound for the prevention or treatment of cancer metastasis in humans or animals.
La présente invention a aussi pour objet l'utilisation d'un composé choisi parmi un composé inhibiteur d'aminopeptidase et un composé aza-indole pour la fabrication d'un médicament destiné à la prévention ou au traitement des métastases cancéreuses chez l'homme ou l'animal.The present invention also relates to the use of a compound selected from an aminopeptidase inhibiting compound and an aza-indole compound for the manufacture of a medicament for the prevention or treatment of cancer metastases in humans or the animal.
Comme cela est illustré dans les exemples, les composés inhibiteurs d'aminopeptidase et les composés aza-indole identifiés selon l'invention ont la capacité d'induire une réversion du phénotype invasif de cellules cancéreuses telles que des cellules de carcinome colo-rectal métastatiques et des cellules d'adénocarcinome mammaire métastatiques.As illustrated in the examples, the aminopeptidase inhibiting compounds and the aza-indole compounds identified according to the invention have the capacity to induce a reversion of the invasive phenotype of cancer cells such as metastatic colorectal carcinoma cells and metastatic mammary adenocarcinoma cells.
De plus, le demandeur a montré que les composés inhibiteurs d'aminopeptidase et les composés aza-indole identifiés selon l'invention ne sont pas cytotoxiques.In addition, the Applicant has shown that the aminopeptidase inhibiting compounds and the azaindole compounds identified according to the invention are not cytotoxic.
Sans vouloir être lié par une quelconque théorie, le demandeur pense que les propriétés anti-métastatiques des composés inhibiteurs d'aminopeptidase et des composés aza-indole identifiés selon l'invention sont dues à la capacité commune de la totalité de ces composés à induire le rétablissement des jonctions cellulaires associées à l'expression de la E-cadhérine à la surface des cellules cancéreuses métastatiques.Without wishing to be bound by any theory, the applicant believes that the anti-metastatic properties of the aminopeptidase inhibiting compounds and of the aza-indole compounds identified according to the invention are due to the common ability of all these compounds to induce the restoration of cellular junctions associated with the expression of E-cadherin on the surface of metastatic cancer cells.
La capacité des composés anti-métastatiques de l'invention à induire l'expression de la E-cadhérine à la surface des cellules cancéreuses et ainsi induire le rétablissement des jonctions cellulaires associées à cette expression de la E-cadhérine peut être vérifiée, notamment en réalisant le test décrit dans la demande PCT publiée sous le n ° WO 2006/134305 (Centra National de la Recherche Scientifique - ROUX Pierre et DE TOLEDO Marion).The ability of the anti-metastatic compounds of the invention to induce the expression of E-cadherin on the surface of the cancerous cells and thus induce the recovery of cellular junctions associated with this expression of E-cadherin can be verified, in particular by performing the test described in the PCT application published under No. WO 2006/134305 (National Center for Scientific Research - ROUX Pierre and TOLEDO Marion).

Part Material and Methods. As a negative control, the cells of the SW620 line incubated in the culture medium alone were used in the absence of an anti-metastatic compound. An average O.D. of 0.147 was obtained.
Comme contrôle positif, on a utilisé des cellules de la lignée HCT1 16 incubées dans le milieu de culture seul, en l'absence de composé anti-métastatique. On a obtenu une D. O. moyenne de 0,734.As a positive control, cells of the HCT1 line 16 were used, incubated in the culture medium alone, in the absence of an anti-metastatic compound. An average O.D. of 0.734 was obtained.
Les essais ont été réalisés en incubant les cellules de la lignée SW620 avec chacun des composés (I) à (Vl).The tests were carried out by incubating the cells of the SW620 line with each of the compounds (I) to (VI).
Dans ces essais, la D. O. moyenne obtenue avec chacun des composés (I) à (Vl) a toujours été supérieure à 0,300, ce qui signifie que les composés (I) à (Vl) sont capables d'induire l'étalement cellulaire, la formation d'îlots cellulaires compacts, et d'induire la génération de néo-jonctions inter-cellulaires de type E-cadhérine.In these tests, the average OD obtained with each of the compounds (I) to (VI) has always been greater than 0.300, which means that the compounds (I) to (VI) are capable of inducing cell spreading, formation of compact cell islands, and to induce the generation of E-cadherin-type inter-cellular neo-junctions.
