    摘要:
    由于人血浆中的酯酶活性低,因此在人体内测试的许多酯和碳酸酯前药可能不如在临床前动物中有效。在这封信中,PTX和SN-38通过碳酸盐连接基连接到2-硝基咪唑的N -1位。据推测,2-氨基咪唑可能有助于促进碳酸酯键的分子内水解。前药在不同pH值的缓冲液中以及在人血浆中显示出相当大的稳定性。此外,在硝基还原酶存在下显示出快速降低。的体外细胞毒性试验表明,缺氧条件下可以增加前药的毒性。潜在地,该化合物物种可能形成一类新的有希望的抗肿瘤剂。

  • NEOADJUVANT USE OF ANTIBODY-DRUG CONJUGATES
    申请人:Immunomedics, Inc.
    公开号:US20160095939A1
    公开(公告)日:2016-04-07
    The present invention concerns improved methods and compositions for neoadjuvant use of antibody-drug conjugates (ADCs) in cancer therapy, preferably ADCs comprising an anthracycline or camptothecin, more preferably SN-38 or pro-2-pyrrolinodoxorubicin (P2PDox). The ADC is administered as a neoadjuvant, prior to treatment with a standard anti-cancer therapy such as surgery, radiation therapy, chemotherapy, or immunotherapy. Neoadjuvant use of the ADC substantially improves the efficacy of standard anti-cancer therapy and may debulk a primary tumor or eliminate micrometasteses. In most preferred embodiments, neoadjuvant ADC in combination with a standard anti-cancer therapy is successful in treating cancers that are resistant to standard treatments, such as triple-negative breast cancer (TNBC).
    本发明涉及改进的方法和组合物,用于抗体药物联合物(ADC)在癌症治疗中的新辅助使用,优选包含环类或喜树碱的ADC,更优选是SN-38或pro-2-pyrrolinodoxorubicin(P2PDox)的ADC。ADC作为新辅助治疗在标准抗癌疗法(如手术、放疗、化疗或免疫疗法)之前给予。ADC的新辅助使用显著提高了标准抗癌疗法的疗效,并可减少原发肿瘤或消除微小转移。在最优选实施例中,新辅助ADC与标准抗癌疗法结合治疗对标准治疗有抵抗的癌症,如三阴性乳腺癌(TNBC)具有成功的疗效。
  • Antibody Conjugates of 7-Ethyl-10-hydroxycamptothecin (SN-38) for Targeted Cancer Chemotherapy

    CPT-11 is a clinically used cancer drug, and it is a prodrug of the potent topoisomerase I inhibitor, SN-38 (7-ethyl-10-hydroxycamptothecin). To bypass the need for the in vivo conversion of CPT-11 and increase the therapeutic index, bifunctional derivatives of SN-38 were prepared for use in anti body-based targeted therapy of cancer. The general synthetic scheme incorporated an acetylene-azide click cycloaddition step in the design, a short polyethylene glycol spacer for aqueous solubility, and a maleimide group conjugation. Conjugates of a humanized anti-CEACAM5 monoclonal antibody, hMN-14, prepared using, these SN-38 derivatives were evaluated in vitro for stability in buffer and human serum and for antigen-binding and cytotoxicity in a human colon adenocarcinoma cell line. Conjugates of hMN-14 and SN-38 derivatives 16 and 17 were found promising for further development.
