New vascular disrupting agents in upper gastrointestinal malignancies.
Antivascular approaches aim to cause rapid and catastrophic shutdown in the vascular function of the tumour, leading to extensive tumour cell death. Tumour vascular disrupting agents (VDAs) are a new class of cancer therapies that target the existing vasculature of tumours, taking advantage of the relative instability of tumour vasculature and its supporting structures. Treatment with VDAs induces a rapid collapse and regression of tumour vessels, with a consequent deprivation of blood and oxygen which leads to ischemic or hemorrhagic necrosis of the tumour. In this review, an overview of the most recently developed vascular disrupting agents is reported, focusing on the biological effects exerted by these compounds on endothelial cells and tumour vasculature, potentially effective in the treatment of several malignancies including upper gastrointestinal tumours. In particular, we have focused on the antimitotic agent combretastatin and its numerous synthetic analogues such as combretastatin A-4-phosphate, OXI4503, and AVE8062, and on the colchicine analogue ZD6126.

[Advances in the study of the anti-tumor activity of small molecule vascular disrupting agents].
Vascular disrupting agents (VDAs) have presented a new kind of anti-cancer drug in recent years. VDAs take advantage of the weakness of established tumor endothelial cells and their supporting structures. In contrast to anti-angiogenic therapy, which inhibits the outgrowth of new blood vessels, vascular targeting treatments selectively attack the existing tumor vasculature. Here we summarized the anti-tumor activities, mechanisms and clinical applications of small molecule VDAs. Topics: Angiogenesis Inhibitors; Animals; Antineoplastic Agents; Bibenzyls; Diphosphates; Endothelial Cells; Humans; Molecular Structure; Neoplasms; Neovascularization, Pathologic; Oligopeptides; Organophosphorus Compounds; Serine; Stilbenes; Tubulin Modulators; Xanthones | 2010 |

Preclinical evaluation of vascular-disrupting agents in Ewing's sarcoma family of tumours.
The effects of the tubulin-binding vascular-disrupting agents (VDAs), combretastatin A4 phosphate (CA4P), OXi4503/CA1P and OXi8007, in subcutaneous mouse models of the Ewing's sarcoma family of tumours (ESFTs) have been investigated alone and in combination with doxorubicin. Delay in subcutaneous tumour growth was observed following treatment of mice with multiple doses of OXi4503/CA1P but not with CA4P or OXi8007. A single dose of OXi4503/CA1P caused complete shutdown of vasculature by 24h and extensive haemorrhagic necrosis by 48h. However, a viable rim of proliferating cells remained, which repopulated the tumour within 10 days following the withdrawal of treatment. Combined treatment with doxorubicin 1h prior to administration of OXi4503/CA1P enhanced the effects of OXi4503/CA1P causing a synergistic delay in tumour growth (p<0.001). This study demonstrates that OXi4503/CA1P is a potent VDA in ESFT and in combination with conventional cytotoxic agents represents a promising treatment strategy for this tumour group.
