    • The invention relates to novel materials based on biodegradable polyamino acids that are useful for vectorizing active principle/s (AP). The aim of the invention is to supply a new polymeric raw material that is used for vectorizing AP and optimally fulfills all requirements concerning biocompatibility, biodegradability, the ability to be easily associated with numerous active principles or solubilize said active principles and to release the active principles in vivo. Said polymers can also be readily and economically transformed into particles vectorizing active principles according to the grafting rate of the hydrophobic groups, said particles being able to form stable aqueous colloidal suspensions. Said aim is achieved by the inventive amphiphile polyamino acids comprising aspartic and/or glutamic units that carry grafts which encompass at least one hydrophobic unit and are linked to the aspartic and/or glutamic units via a rotula containing two amide functions, more particularly via a spacer of the lysine or ornithine type. Said amide functions ensure better stability during hydrolysis than comparable products known in prior art. The invention also relates to new pharmaceutical, cosmetic, dietetic, or phytosanitary compositions based on the inventive polyamino acids.

    • The present invention relates to novel biodegradable materials based on modified polyamino acids that are useful in particular in the vectorization of active principle(s) (APs). The invention is also directed to novel pharmaceutical, cosmetic, health-food or plant-protection compositions based on these polyamino acids.The aim of the invention is to provide a novel polymeric starting material which can be used for AP vectorization and which satisfy all the requirements: biocompatibility, biodegradability, ability to easily associate with or dissolve numerous active principles and to release these active principles in vivo. This goal is achieved by the present invention, which relates to novel polyglutamates modified by cationic groups, which, if they can be deprotonated, exhibit a pKa equal to or greater than 7, and by hydrophobic groups comprising from 8 to 30 carbon atoms.These polyglutamates modified by cationic groups are easily and economically converted into particles for the vectorization of active principles, these particles being themselves capable of forming stable aqueous colloidal suspensions. These modified polyglutamates exhibit the advantage of being less viscous than other analogous polymers while retaining an ability to associate proteins, such as insulin. Some are soluble in water at acidic pH and become insoluble at physiological pH (7.4) and should thus, during subcutaneous injection, precipitate on the site of injection.
    • 本发明涉及基于改性聚氨基酸的新型可生物降解材料，其特别用于活性成分（AP）的向量化。 本发明还涉及基于这些聚氨基酸的新型药物，化妆品，保健食品或植物保护组合物。 本发明的目的是提供一种新颖的聚合起始材料，其可用于AP向量化，并且其满足所有要求：生物相容性，生物降解性，容易地与许多活性成分缔合或溶解的能力，并在体内释放这些活性成分。 该目的通过本发明来实现，本发明涉及由阳离子基团修饰的新的聚谷氨酸，如果它们可以去质子化，表现出等于或大于7的pKa，以及含有8至30个碳原子的疏水基团。 通过阳离子基团改性的这些聚谷氨酸可容易且经济地转化成用于活性成分载体化的颗粒，这些颗粒本身能够形成稳定的水性胶态悬浮液。 这些改性的聚谷氨酸显示出比其它类似聚合物粘稠度较低的优点，同时保留了使蛋白质如胰岛素相关联的能力。 一些在酸性pH下溶于水，在生理pH（7.4）下变得不溶，因此皮下注射时，在注射部位沉淀。
