Chemical conjugates which comprise an oligopeptide covalently bonded, either directly or through a chemical linker, to a peptide or small molecule that binds to an anti-apoptotic Bcl-2 family protein, inhibits the expression of the Bcl-2 family protein, or inhibits the function of the Bcl-2 family protein. Such a peptide or small molecule that binds to an anti-apoptotic Bcl-2 family protein, inhibits the expression of the Bcl-2 family protein, or inhibits the function of the Bcl-2 family protein may be conveniently referred to as a therapeutic agent. The oligopeptides are chosen from oligomers that are selectively recognized by the free prostate specific antigen (PSA) and are capable of being proteolytically cleaved by the enzymatic activity of the free prostate specific antigen.
化学共轭物是由寡肽与与抗凋亡Bcl-2家族蛋白结合、抑制Bcl-2家族蛋白表达或抑制Bcl-2家族蛋白功能的肽或小分子,通过化学连接剂直接共价键合而成。这样的肽或小分子可方便地称为治疗剂。寡肽是从被游离的前列腺特异性抗原(PSA)选择性识别的寡聚体中选择的,并能够被游离的前列腺特异性抗原酶解活性所切割。
