Abstract: La présente invention concerne de nouvelles microparticules de polyaminoacides amphiphiles transporteurs de principe(s) actif(s) -PA-, en particulier protéinique(s) et peptidique(s), ainsi que de nouvelles formulations pharmaceutiques à libération modifiée contenant lesdites microparticules de PA. Le but de l'invention est de mettre au point de nouvelles microparticules chargées en PA obtenues par agrégation de nanoparticules de polyaminoacides amphiphiles, et ayant des propriétés améliorées, notamment sous forme solide sèche, au regard de leur aptitude à la dispersion, et, s'agissant de la suspension reconstituée, de sa stabilité et de son aptitude à être facilement manipulée et injectée. L'invention concerne dans un premier aspect, des microparticules de polyaminoacide amphiphile (PO) contenant au moins un PA (associé de façon non covalente), formant spontanément une suspension colloïdale de nanoparticules dans l'eau, à pH 7,0, en condition isotonique; lesdites microparticules étant caractérisées a. en ce qu'elles sont obtenues par atomisation d'une solution ou d'une suspension colloïdale de PO comprenant au moins un PA, b. par une taillecomprise entre 0,5 et 100 µm, c. et en ce qu'elles sont dispersables en suspension colloïdale. L'invention concerne également le procédé de préparation de ces microparticules, une formulation liquide comprenant une suspension de ces microparticules PO/PA, un procédé et un nécessaire de reconstitution de cette formulation, et une forme sèche de cette formulation.

Abstract: The novel positively charged pro-drugs of prostaglandins, prostacyclins and related compounds in the general formula (2) 'Structure 2' were designed and synthesized. The compounds of the general formula (2) 'Structure 2' indicated above can be prepared from protected prostaglandins, prostacyclins, and related compounds, by reaction with suitable alcohols, thiols, or amines and coupling reagents, such as N, N'-Dicyclohexylcarbodiimide, N, N'-Diisopropylcarbodiimide, O-(Benzotriazol-1-yl)-N,N,N',N'-tetramethyluronium tetrafluoroborate, O-(Benzotriazol-1-yl)-N,N,N',N'-tetramethyluronium hexafluorophosphate, Benzotriazol-1-yl-oxy-tris (dimethylamino)phosphonium hexafluorophosphate, et al. The positively charged amino groups of these pro-drugs not only largely increases the solubility of the drugs in water, but also bonds to the negative charge on the phosphate head group of membranes and pushes the pro-drug into the cytosol. The results suggest that the pro-drugs diffuse through human skin ~1000 times faster than do prostaglandins, prostacyclins, and related compounds. In plasma, more than 90% of these pro-drugs can change back to the parent drugs in a few minutes. The prodrugs can be used medicinally in treating any prostaglandins, prostacyclins, and related compounds-treatable conditions in humans or animals. The prodrugs can be administered transdermally for any kind of medical treatments and avoid most of the side effects of prostaglandins, prostacyclins, and related compounds. Controlled transdermal administration systems of the prodrug enable prostaglandins, prostacyclins, and related compounds to reach constantly optimal therapeutic blood levels to increase effectiveness and reduce the side effects of prostaglandins, prostacyclins, and related compounds. Another great benefit of transdermal administration of these pro-drugs is that administering medication, especially to children, will be much easier.
