By using a bispecific monoclonal antibody recognising both carcinoembryonic antigen (CEA) and the cytostatic vinca alkaloid drugs we have been able to show specific tumour localisation of vinca alkaloids. In vitro studies with sections of human colorectal tumours have demonstrated that the hybrid-hybrid 28.19.8 monoclonal is able to specifically localise vindesine to cells expressing CEA. Furthermore, the hybrid-hybrid 28.19.8 localises in vivo preferentially to tumour tissues in nude mice bearing the MAWI human xenograft tumour. This tumour-bound hybrid-hybrid monoclonal antibody induces profound changes in the bio-distribution of vinca alkaloid drugs, targeting them specifically to tumour tissues.
通过使用一种双特异性单克隆抗体,该抗体可识别癌胚抗原(CEA)和细胞生长抑制剂长春花生物碱类药物,我们得以展示长春花生物碱类药物在肿瘤部位的特异性定位。对人结肠肿瘤切片进行的体外研究表明,杂交-杂交单克隆抗体28.19.8能够将长春地辛特异性定位到表达CEA的细胞上。此外,杂交-杂交单克隆抗体28.19.8在体内优先定位于携带MAWI人异种移植肿瘤的裸鼠的肿瘤组织。这种与肿瘤结合的杂交-杂交单克隆抗体可诱导长春花生物碱类药物的生物分布发生显著变化,使其特异性靶向肿瘤组织。
