  Synthesis of an immunoconjugate of camptothecin

  摘要：

  The first immunoconjugate of camptothecin has been synthesized wherein the drug is attached to the tumor-recognizing antibody BR96 via a Cathepsin B cleavable linker. Endocytosis of the immunoconjugate upon binding to the tumor cell followed by enzymatic cleavage of the linker inside the endosome ensures tumor-specific release of the drug. In this way, it is hoped that the dose-limiting side effects associated with camptothecin can be eliminated while the antitumor activity is preserved. (C) 2002 Elsevier Science Ltd.

• Cobalamin conjugates for anti-tumor therapy

  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。
• Monomethoxytrityl (MMT) as a versatile amino protecting group for complex prodrugs of anticancer compounds sensitive to strong acids, bases and nucleophiles

  日期：1997.7

  Cathepsin B-sensitive maleimidocaproyl-Phe-Lys linker compounds containing acid-sensitive anticancer drugs doxorubicin, mitomycin C and paclitaxel (taxol(R)) attached through a self-immolative p-aminobenzylcarbonyl spacer were prepared using monomethoxytrityl (MMT) as the amino protecting group for Lys. MMT could be removed cleanly and in high yield by dichloroacetic and chloroacetic acids in the presence of anisole with minimal workup. (C) 1997 Elsevier Science Ltd.
