Two-domain vascular disruptive agents in cancer therapy

Current Cancer Drug Targets
Stanisław Szala

Abstract

The two-domain vascular drug constructs are selective anti-cancer agents capable of specific targeting and subsequent elimination of endothelial cells lining tumor blood vessels. The destruction of existing vasculature within tumor tissue causes insufficient oxygenation of adjacent neoplastic cells and their necrotic death. The recognition (cognitive) domain of the vascular disruptive agents is responsible for recognizing markers specific for endothelial cells. This domain can be formed by variable regions of antibodies or by suitable ligands (such as those binding various integrin or growth factor receptors). The effector domain, in turn, can be constructed from proteins participating in blood clotting process, as well as from toxins, cytokines, radioactive isotopes or pro-apoptotic factors. This article outlines issues important for constructing such two-domain vascular disruptive agents and emphasizes the modularity of their assembly. Several pharmacokinetic and pharmacodynamic properties of these novel agents are discussed. Compared to known cytostatic substances exerting anti-angiogenic effects, such vascular disruptive agents can be much more effective as cytotoxic agents, especially in combination with proven anti-cancer...Continue Reading

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function. Discover the latest research on adhesion molecule and their role in health and disease here.

Angiogenesis Inhibitors to Treat Cancer

Cancer treatments including angiogenesis inhibitors prevent tumor cells from receiving nutrients and oxygen. Here is the latest research on angiogenesis inhibitors for the treatment of cancer.

Cancer Metabolism: Therapeutic Targets

Targeting the mechanisms by which cancer cells acquire energy for metabolic needs is a therapeutic target. Discover the latest research on cancer metabolism and therapeutic targets.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
