Metals are essential cellular components that have been hand-picked by nature to perform a range of activities in biochemical processes that are absolutely necessary for living creatures. Metals are required in order for biochemical processes to take place, hence live organisms cannot exist without them. The existence of transition metal complexes is essential to a variety of chemical and biological processes, including catalysis, the synthesis of materials, photochemistry, and the operation of biological systems. Medicinal inorganic chemistry offers the ability to make advantage of the specific properties of metal ions throughout the process of producing new drugs. For medicinal purposes, a wide variety of metals and salts derived from those metals have been used throughout the whole of human history. As the field of inorganic chemistry continues to make progress toward development, the relevance of transition metal complexes as therapeutic molecules is becoming more crucial. Because of recent advancements in inorganic chemistry, it is now possible to create a wide range of transition metal complexes with organic ligands of interest. These complexes have the potential to be used as therapeutic agents. It was previously believed that it was impossible to construct complexes like this. The purpose of this study is to offer an overview of the function of metals as well as recent developments in the field of medical bioinorganic chemistry. The study focuses on unique tactics for the production of revolutionary metal-based drugs and their prospective applications.
