Introduction of Selenosemicarbazone

Abstract
This paper is designed to explain the introduction of selenosemicarbazone. Selenosemicarbazones are schiff bases characterized by the presence of selenium and azomethine nitrogen offering a ready co-ordination site due to the presence of a lone pair of electrons on these donor atoms. Selenosemicarbazone can adopt a variety of different coordination modes. selenosemicarbazone and their complexes showed good biological activity such as antifungal , antiparasitic , antibacterial , antimalarial , anticancer , anti-oxidant, anti-proliferative , anti-angiogenic and antidiabetic activity . Keywords - Selenosemicarbazone, Co-ordination, Biological activity.
