Abstract: Organometallic compounds have recently found applications in medicinal chemistry and as diagnostic tools in chemical biology. Naturally occurring biomolecules, viz., cobalamine, NiFe hydrogenase, Acetyl-CoA synthase, etc., also contain metal-carbon bonds. Among organometallic compounds having medicinal importance, (arene)ruthenium complexes, radioactive technetium complexes and ferrocene conjugates are notable ones. Applications of photoactive organometallic complexes or metal complexes conjugated with an organometallic moiety are of recent origin. Photodynamic therapy (PDT) is a promising method to treat cancer cells in presence of light. This review primarily focuses on different aspects of the chemistry of organometallic complexes showing photocytotoxic activities. Half-sandwich tungsten, iron or ruthenium complexes are known to show photonuclease and/or photo-crosslinking activity. Photoinduced organometallic CO releasing molecules also exert photocytotoxic activity. Attempts have been made in this review to highlight the photocytotoxic behavior of various metal complexes when conjugated with a photoactive organometallic moiety, viz., ferrocene.
