  The present invention provides a cobalamin-drug conjugate suitable for the treatment of tumor related diseases. Cobalamin is indirectly covalently bound to an anti-tumor drug via a cleavable linker and one or more optional spacers. Cobalamin is covalently bound to a first spacer or the cleavable linker via the 5′-OH of the cobalamin ribose ring. The drug is bound to a second spacer of the cleavable linker via an existing or added functional group on the drug. After administration, the conjugate forms a complex with transcobalamin (any of its isoforms). The complex then binds to a receptor on a cell membrane and is taken up into the cell. Once in the cell, an intracellular enzyme cleaves the conjugate thereby releasing the drug. Depending upon the structure of the conjugate, a particular class or type of intracellular enzyme affects the cleavage. Due to the high demand for cobalamin in growing cells, tumor cells typically take up a higher percentage of the conjugate than do normal non-growing cells. The conjugate of the invention advantageously provides a reduced systemic toxicity and enhanced efficacy as compared to a corresponding free drug.

  本发明提供了一种适用于治疗肿瘤相关疾病的钴胺素-药物结合物。钴胺素通过可切割的连接剂间接共价结合到抗肿瘤药物上，还可以通过一个或多个可选的间隔物。钴胺素通过其核糖环的5'-OH与第一间隔物或可切割连接剂共价结合。药物通过其现有或添加的功能基团与可切割连接剂的第二间隔物结合。在给药后，结合物与转钴胺素（其任何同工异构体）形成复合物。然后，该复合物结合到细胞膜上的受体并被细胞摄取。一旦进入细胞，细胞内酶将切割结合物，从而释放药物。根据结合物的结构，特定类别或类型的细胞内酶影响切割。由于生长细胞对钴胺素的需求量较高，肿瘤细胞通常摄取结合物的比例高于正常非生长细胞。本发明的结合物与相应的游离药物相比，具有较低的全身毒性和增强的疗效。

  The invention provides a therapeutic drug and targeting conjugate, pharmaceutical compositions containing these conjugates in pharmaceutical composition, and uses of these conjugates in anti-neoplastic and other therapeutic regimens. Also provided are novel intermediates thereof. The conjugates provide a therapeutic drug fragment or prodrug fragment bound to a targeting moiety via a linker which comprises a substrate cleavable by a protease such as Cathepsin B. The targeting moiety is a ligand which targets a cell surface molecule, such as a cell surface receptor on an anti-neoplastic cell. The ligand may function solely as a targeting moiety or may itself have a therapeutic effect. Following administration of the therapeutic drug and targeting conjugate of formula I and exposure of the conjugate to the protease specific for the substrate, the linker is cleaved and the targeting moiety is separated from the conjugate, which causes the drug fragment or prodrug fragment to convert to the drug or prodrug. The recited conjugates are useful in anti-neoplastic therapies. Also provided are methods of making the therapeutic drug and targeting conjugates and intermediates thereof, and kits comprising the therapeutic drug and targeting conjugates.

  该发明提供了一种治疗药物和靶向共轭物，包含这些共轭物的药物组合物，以及这些共轭物在抗肿瘤和其他治疗方案中的用途。还提供了其新颖的中间体。这些共轭物通过一个由蛋白酶如半胱氨酸蛋白酶B可切割的底物组成的连接物将治疗药物片段或前药片段与靶向基团结合。靶向基团是一个以细胞表面分子为靶点的配体，例如抗肿瘤细胞上的细胞表面受体。该配体可能仅作为靶向基团，也可能本身具有治疗效果。在给药公式I的治疗药物和靶向共轭物并使共轭物暴露于特异于底物的蛋白酶的情况下，连接物被切割，靶向基团与共轭物分离，导致药物片段或前药片段转化为药物或前药。所述的共轭物在抗肿瘤疗法中很有用。还提供了制备治疗药物和靶向共轭物及其中间体的方法，以及包含治疗药物和靶向共轭物的试剂盒。

  Peptide-drug conjugates comprising p-aminobenzyl carbamoyl or p-aminobenzolyl carbonate self-immolating linkers are disclosed. The peptide-drug conjugates comprise a peptide moiety that can be cleaved by cellular proteases, bound to the self-immolating linker, which linker is bound to a cytotoxic drug moiety. Upon cleavage of the peptide moiety, the linker self- immolates, releasing the cytotoxic drug in active form. Dimeric structures of the peptide drug conjugates comprising two molecules of cytotoxic drug per conjugate are also disclosed.
