Abstract

In last years, hhere have been some notable developments as several areas of inorganic pharmaceutical that have potentially for � reacting importance for future medicial applications and reasearch. One of the highly significant developmeats in the field of oncology and hematology is the application role selenium compounds. Selenium ions play an important role in biological systems, and without their catalytic presence interrace or ultratrace amouts many essential co � factors for many biochemical reactions would endogenous antioxidant enzymes. Selenium is an essential component of several endogenous antioxidant enzymes. Selenium affects the transugtion of multiple defense and regair genes to protect against metal � induced pathologies. Selenium creates stable compleces a wide variety of organic molecules that canprovide required biological afinity and therapeutical activity veritable for tangeling specific locations in the body. The aim of this revier is a critical evalution of selenium complexes used for therapy or diagnosis of various diseases in oncology.
