VDA chemical products
Vascular disrupting agents (VDAs) are chemical compounds designed to selectively target and disrupt the established blood vessels that supply tumors with oxygen and nutrients. Unlike traditional anti-angiogenic therapies that aim to inhibit the formation of new blood vessels (angiogenesis), VDAs specifically attack existing tumor vasculature, leading to rapid and extensive shutdown of blood flow to the tumor. This process, known as vascular disruption, deprives tumor cells of essential nutrients and oxygen, resulting in necrosis and tumor cell death. VDAs typically act by binding to tubulin within endothelial cells lining the blood vessels, causing destabilization and subsequent collapse of the vessel structure. Examples of VDAs include combretastatin A-4 phosphate and CA4P derivatives, which have been studied in preclinical and clinical settings for their potential as effective treatments in various cancers.
