The present invention relates to the field of oncology, laboratory tools and methods, and especially anti-tumor DNA crosslinking agents. Most patients with advanced solid tumors develop resistance to chemotherapy due to the ability of cancer cells to repair or tolerate sustained DNA damages. The inventors showed that the compounds according to the present invention allow the detection and visualization of alkylated DNA damages induced by PBDs without altering their DNA crosslinking ability. This enables the study of the effect and properties of PBDs. In particular, the present invention relates new derivates of PBD molecules and their synthesis. The present invention also relates to a method for visualizing DNA crosslinking; to a method for assessing the resistance of a tumor to a crosslinking agent and to a method for identifying a molecule or treatment for improving the efficiency of a crosslinking agent.
本发明涉及肿瘤学、实验室工具和方法领域,特别是抗肿瘤DNA交联剂。大多数晚期实体肿瘤患者由于癌细胞修复或耐受持续DNA损伤的能力而对化疗产生抗药性。发明人表明,根据本发明的化合物允许检测和可视化由PBDs诱导的烷基化DNA损伤,而不会改变它们的DNA交联能力。这使得可以研究PBDs的效果和性质。具体来说,本发明涉及PBD分子的新衍生物及其合成。本发明还涉及一种可视化DNA交联的方法;一种评估肿瘤对交联剂抗性的方法,以及一种识别分子或治疗方法以提高交联剂效率的方法。
