The present invention is directed to novel bifunctional CTI-CTI and CBI-CTI dimers of the formula:
F
1
-L
1
-T-L
2
-F
2
where F
1
, L
1
, T, L
2
and F
2
are as defined herein, useful for the treatment for proliferative diseases, where the inventive dimers can function as stand-alone drugs, payloads in antibody-drug-conjugates (ADCs), and linker-payload compounds useful in connection with the production or administration of such ADCs; and to compositions including the aforementioned dimers, linker-payloads and ADCs, and methods for using these dimers, linker-payloads and ADCs, to treat pathological conditions including cancer.
本发明涉及新颖的具有双重功能的CTI-CTI和CBI-CTI二聚物,其公式为:
F1-L1-T-L2-F2
其中F1、L1、T、L2和F2如本文所述定义,用于治疗增殖性疾病,其中发明的二聚物可以作为独立药物、抗体药物偶联物(ADCs)中的有效载荷以及与生产或施用此类ADCs相关的连接器有效载荷化合物;以及包括前述二聚物、连接器有效载荷和ADCs的组合物,以及使用这些二聚物、连接器有效载荷和ADCs治疗包括癌症在内的病理状况的方法。
