COMPOSES ANTIMITOTIQUES DERIVES D'ALCALOÏDES DE VINCA, LEUR PREPARATION ET LEUR APPLICATION EN THERAPEUTIQUE. ANTIMITOTIC COMPOUNDS DERIVED FROM VINCA ALKALOIDS, THEIR PREPARATION AND THEIR USE IN THERAPEUTICS.
IntroductionIntroduction
Les alcaloïdes du Catharanthus roseus et leurs dérivés, communément dénommés alcaloïdes de Vinca, sont largement utilisés dans le traitement de la pathologie cancéreuse.The alkaloids of Catharanthus roseus and their derivatives, commonly known as Vinca alkaloids, are widely used in the treatment of cancer pathology.
Dans le cadre de nos travaux visant à synthétiser de nouveaux composés dérivés de ces alcaloïdes et pouvant conduire à de nouvelles applications en chimiothérapie anticancéreuse, nous avons adopté une démarche originale en appliquant la chimie en milieu superacide à ces composés hautement fonctionnalisés. La numérotation employée pour décrire les différents composés cités répond aux normes définies par " The International Union ofPure and Applied Chemistry (IUPAC)". La vinflunine est un dérivé indolique de la famille de la vinblastine et de la vincristine.As part of our work to synthesize new compounds derived from these alkaloids and may lead to new applications in cancer chemotherapy, we have adopted an original approach by applying superacid chemistry to these highly functionalized compounds. The numbering used to describe the various compounds mentioned meets the standards defined by "The International Union of Pharmaceutical and Applied Chemistry (IUPAC)". Vinflunine is an indole derivative of the vinblastine and vincristine family.
Vinblastine R=CH3 Vincristine R=CHOVinblastine R = CH 3 Vincristine R = CHO
Ces composés font partie des alcaloïdes antimitotiques, extraits de Catharanthus roseus, et sont utilisés depuis de nombreuses années en chimiothérapie anticancéreuse. Les difficultés d'obtention de ces dérivés par extraction à partir des plantes ont conduit plusieurs groupes de recherche à identifier de nouvelles substances voisines ayant les mêmes propriétés et à mettre au point leur procédé d'obtention par hémisynthèse. Ainsi la vindesine et la vinorelbine (Navelbine) ont pu être obtenues et commercialisées pour le
traitement de cancers. La structure chimique des ces composés présente comme caractère principal l'association de deux monomères alcaloïdes, la catharanthine et la vindoline.These compounds are part of the antimitotic alkaloids, extracted from Catharanthus roseus, and have been used for many years in anticancer chemotherapy. The difficulties in obtaining these derivatives by extraction from plants have led several research groups to identify new neighboring substances having the same properties and to develop their method of production by semisynthesis. Thus vindesine and vinorelbine (Navelbine) could be obtained and marketed for cancer treatment. The chemical structure of these compounds has as main character the association of two alkaloid monomers, catharanthine and vindoline.
Vindesine VinorelbineVindesine Vinorelbine
Dans le cadre de la mise au point de nouvelles voies synthétiques pour obtenir la vinorelbine, la réactivité de ce composé en milieu super acide a conduit à identifier une nouvelle molécule, la 20',20'-difluoro-3',4'-dihydrovinorelbine, ou vinflunine. L'intérêt thérapeutique de ce composé a également pu être vérifié au cours des mêmes travaux.As part of the development of new synthetic routes for vinorelbine, the reactivity of this compound in a super acidic medium led to the identification of a new molecule, 20 ', 20'-difluoro-3', 4'-dihydrovinorelbine , or vinflunine. The therapeutic interest of this compound could also be verified during the same work.

Les alcaloïdes antitumoraux du Catharanthus roseus sont des poisons du fuseau mitotique, c'est-à-dire qu'ils inhibent la polymérisation de la tubuline en microtubules. Ce phénomène a pour conséquence de bloquer la division cellulaire au stade de la mitose, entraînant à terme la mort des cellules.The antitumor alkaloids of Catharanthus roseus are mitotic spindle poisons, that is, they inhibit the polymerization of tubulin into microtubules. This phenomenon has the effect of blocking cell division at the stage of mitosis, eventually leading to cell death.
L'activité cytotoxique des composés préparés selon l'invention a donc été évaluée en mesurant l'inhibition de la prolifération cellulaire de lignées tumorales d'origine humaine, telle la lignée A549. Cette activité est exprimée par l'IC50, concentration de produit testé capable d'inhiber à 50 % la prolifération cellulaire. La méthode employée est la mesure par luminescence de l'ATP résiduel après 72h00 d'incubation en utilisant le kit « ATP Lite » commercialisé par Perkin Elmer.
A titre d'exemple, les propriétés cytotoxiques de quelques composés de l'invention sont reportées dans le Tableau 3.The cytotoxic activity of the compounds prepared according to the invention was therefore evaluated by measuring the inhibition of the cell proliferation of tumor lines of human origin, such as the A549 line. This activity is expressed by the IC 50 concentration of tested product capable of inhibiting 50% cell proliferation. The method used is the luminescence measurement of the residual ATP after 72 hours of incubation using the "ATP Lite" kit marketed by Perkin Elmer. By way of example, the cytotoxic properties of some compounds of the invention are reported in Table 3.
Tableau 3 : Cytotoxicité des produits de l'invention évalués sur la lignée A549.Table 3: Cytotoxicity of the products of the invention evaluated on the A549 line.
Compte-tenu de ces propriétés cytotoxiques, les composés selon la présente invention peuvent être utilisés en thérapeutique humaine dans le traitement de la pathologie cancéreuse et les préparations pharmaceutiques contenant ces principes actifs peuvent être mises en forme pour l'administration par voie intraveineuse ou sous-cutanée voire orale, sous forme de capsules, comprimés, gélules adaptés à la clinique humaine.
In view of these cytotoxic properties, the compounds according to the present invention can be used in human therapy in the treatment of cancer pathology and pharmaceutical preparations containing these active principles can be shaped for intravenous or subcutaneous administration. dermal or even oral, in the form of capsules, tablets, capsules adapted to the human clinic.
