The alpha v integrin antagonists as novel anticancer agents: an update

Expert Opin Investig Drugs. 2002 Dec;11(12):1765-74. doi: 10.1517/13543784.11.12.1765.


Integrins are involved in many cellular processes, including some pathological ones associated with various cancers, both solid tumours and metastases. Since integrins are involved in such critical processes as gene expression, which lead to cellular proliferation, migration, survival and angiogenesis, they represent potential targets for therapeutic intervention. The alpha(v)beta(3) integrin is one of the most widely studied integrins because it is one of the most promiscuous. Published studies provide compelling evidence that small molecule antagonists have the potential to treat both solid tumours and metastases, serve as diagnostic imaging agents and be used for site-directed delivery of drugs to solid tumours. The alpha(v)beta(3) integrin antagonists also inhibit blood vessel formation associated with tumour growth. Therapeutic candidates have included antibodies, cyclic peptides, peptidomimetics and small molecules. A number of potent small-molecule antagonists of the alpha(v)beta(3) integrin have now been identified and are progressing in the clinic. This review focuses on the role of alpha(v)beta(3) in cancer. The rationale for the development of the therapeutic and diagnostic candidates based on the key role of alpha(v)beta(3) is discussed.
