The present invention concerns multifunctional antibody construct containing at least one antibody Ab and two distinct payloads D1and D2of structure (1) or (2). Wherein L1, L2, L3, L4and L5are linkers; x1 and x2 are each individually an integer in the range of 1 – 8, wherein x1 + x2 = 2 - 10; BM is a branching moiety; m and n are each independently 0 or 1; x3 is an integer in the range of 1 - 4; and D1and D2are two distinct payloads selected from the group consisting of polypeptides, small molecules, cytotoxins and oligonucleotides, wherein at least one of D1and D2is a polypeptide. The multifunctional antibody construct according to invention are suitable for use in medicine, such as for use in the treatment of cancer, a viral infection, a bacterial infection, a neurological disease, an autoimmune disease, an eye disease, hypercholesterolemia and amyloidosis.
本发明涉及一种多功能抗体构造体,该构造体包含至少一种抗体Ab和两种不同的结构(1)或(2)的有效载荷D1和D2。其中,L1、L2、L3、L4和L5是连接物;x1和x2分别是1-8范围内的整数,其中x1 + x2 = 2-10;BM是分支基团;m和n各自独立地为0或1;x3是1-4范围内的整数;D1和D2是从包括多肽、小分子、细胞毒素和寡核苷酸在内的一组不同有效载荷中选择的两种不同有效载荷,其中至少一个是多肽。本发明的多功能抗体构造体适用于医学,例如用于治疗癌症、病毒感染、细菌感染、神经系统疾病、自身免疫性疾病、眼部疾病、高胆固醇血症和淀粉样变性疾病。
