Abstract
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.

Chalcogen-modified nucleic acid analogues
Chalcogen-modified nucleosides, nucleotides and oligonucleotides have been of great interest to scientific research for many years. The replacement of oxygen in the nucleobase, sugar or phosphate backbone by chalcogen atoms (sulfur, selenium, tellurium) gives these biomolecules unique properties resulting from their altered physical and chemical properties. The continuing interest in ...read more
