The present invention relates to targeting an intracellular enzyme for release of covalently linked bioactives which results in a synergistic effect between the bioactives. The present invention relates to the use of bioactives that are directly connected covalently or through a covalent molecular linker which have increased therapeutic activity when released as the free bioactives by intracellular enzymes as compared to when the bioactives are administered individually (i.e. not covalendy linked). Further, methods are described of administering to patients in need thereof, bioactives as linked bioactives having increased therapeutic activity. Accordingly, this invention also relates to methods of treating patients for certain diseases.
本发明涉及靶向细胞内酶释放共价连接的
生物活性物质,从而使
生物活性物质之间产生协同效应。本发明涉及直接共价连接或通过共价分子连接体连接的
生物活性物质的使用,与单独施用
生物活性物质(即未共价连接)相比,这些
生物活性物质在作为游离
生物活性物质被细胞内酶释放时具有更高的治疗活性。此外,本发明还描述了向有需要的患者施用
生物活性物的方法,这些
生物活性物作为连接的
生物活性物具有更高的治疗活性。因此,本发明还涉及治疗患者某些疾病的方法。
