The present invention relates to cytostatics which have a tumour-specific action as a result of linkage to α
v
β
3
integrin antagonists via preferred linking units. The preferred linking units guarantee serum stability of the conjugate of cytostatic and α
v
β
3
integrin antagonist and at the same time the desired intracellular action in tumour cells as a result of their enzymatic or hydrolytic cleavability with release of the cytostatic.
本发明涉及细胞毒药物,由于与αvβ3整合素拮抗剂通过优选连接单元的连接而具有肿瘤特异性作用。优选连接单元保证细胞毒药物和αvβ3整合素拮抗剂的结合物在血清中的稳定性,同时由于它们在肿瘤细胞内的酶解或水解性而释放细胞毒药物,从而实现所需的细胞内作用。
