  Synthesis and Biological Evaluation of Novel Prodrugs of Anthracyclines for Selective Activation by the Tumor-Associated Protease Plasmin

  摘要：

  New prodrugs of daunorubicin and doxorubicin designed for selective activation by the serine protease plasmin are described. The low toxic prodrugs 3, 4, and 5 are converted to the corresponding cytotoxic drugs upon proteolysis by the tumor-associated protease plasmin. Application of a self-eliminating spacer was essential for enzyme activation. A prodrug containing a chloro-substituted spacer was synthesized with the aim of enhancing the rate of conversion by plasmin. All prodrugs were highly stable in buffer solution and in serum and on the average 15-fold less cytotoxic than the parent drugs in seven human tumor cell lines. A marked in vitro selectivity was demonstrated by incubation of the doxorubicin prodrugs with a plasmin generating MCF-7 breast cancer cell. line transfected with urokinase-type plasminogen activator (u-PA) in comparison with the nontransfected nonplasmin generating cell line. Prodrugs 4 and 5 showed the same cytotoxic effect as the free parent drug doxorubicin in the u-PA transfected cells, indicating complete conversion of the prodrug by plasmin. Addition of the plasmin inhibitor Trasylol drastically increased the ID50 values in the u-PA transfected MCF-7 cells for both prodrugs 4 and 5.

  The first prodrugs of camptothecin and 9-aminocamptothecin that are activated by the tumour-associated protease plasmin are reported. The tripartate prodrugs consist of a tripeptide sequence recognised by plasmin, which is linked to the 20-hydroxyl group of the camptothecins via a 1,6-elimination spacer. After selective N-protection of 9-aminocamptothecin with an Aloc group, the promoiety (tripeptide-spacer conjugate) was linked to camptothecin or 9-Aloc-9-aminocamptothecin via a 20-carbonate linkage by reacting parent drugs with the p-nitrophenyl carbonate activated promoiety in the presence of DMAP. Both prodrugs showed to be stable in buffer solution and both parent drugs were released upon incubation in the presence of plasmin. Furthermore, the prodrugs showed an average 10-fold decreased cytotoxicity with respect to their parent drugs upon incubation in seven human tumour cell lines. (C) 2002 Elsevier Science Ltd.

  Doxazolidine (doxaz) is a new anthracycline anticancer agent. While structurally similar to doxorubicin (dox), doxaz acts via a distinct mechanism to selectively enhance anticancer activity over cardiotoxicity, the most significant clinical impediment to successful anthracycline treatment. Here, we describe the synthesis and characterization of a prodrug platform designed for doxaz release mediated by secreted proteolytic activity, a common association with invasiveness and poor prognosis in cancer patients. GaFK-Doxaz is hydrolyzable by the proteases plasmin and cathepsin B, both strongly linked with cancer progression, as well as trypsin. We demonstrate that activation of GaFK-Doxaz releases highly potent doxaz that powerfully inhibits the growth of a wide variety of cancer cells (average IC50 of 8 nM). GaFK-Doxaz is stable in human plasma and is poorly membrane permeable, thereby limiting activation to locally secreted proteolytic activity and reducing the likelihood of severe side effects.

Prodrugs in which the novel spacer systems were incorporated between a specific tripeptide specifier and the parent drug doxorubicin or paclitaxel proved to be significantly faster activated by plasmin in comparison with prodrugs containing conventional spacer systems. It is expected that the generally applicable novel spacer systems reported herein will
