The invention relates to chimera molecules for targeting and releasing therapeutic compounds in mammals, especially humans. The inventive molecules comprise essentially three functional segments or domains: a targeting segment that can preferentially bind to the surface of the targeted cells, a therapeutic segment comprising the biologically active compound, and a linker segment between the targeting segment and the therapeutic segment, the linker segment being cleavable onto the target site. The invention also relates to the preparation of said molecules, to synthesis intermediates or domains thereof, to pharmaceutical compositions containing the same, and to the use thereof, especially in the pharmaceutical field. The molecules and compositions according to the invention are especially adapted to the targeting of pathological cells engaged in an apoptotic phase, and to the treatment of pathologies or associated tissues, especially cancers and inflammation.
该发明涉及嵌合分子,用于在哺乳动物,尤其是人类中靶向和释放治疗化合物。这种创新的分子主要包括三个功能段或结构域:一个能够优先结合到目标细胞表面的靶向段,一个包含
