Metal complexes play an essential role in pharmaceutical sciences for their multiple and important activities. Schiff bases are versatile pharmacophores able to form chelating complexes with several metals in different oxidation states. Complexes with Schiff bases are widely described in the literature for their multiple actions and numerous advantages, such as low cost and easy synthesis. They show multiple biological activities, including antimicrobial, antioxidant, antimalarial, antinflammatory and antitumor. Schiff bases may also form complexes with lanthanides and actinides acting as catalysts (e.g., in various synthetic processes) and antitumor agents. This review intends to extend on our previous paper regarding Schiff bases as antitumorals, highlighting the importance, in the field of the anticancer agents, of these tools as ligands of metal complexes.

Metal complexes are currently potential therapeutic compounds. The acquisition of resistance by cancer cells or the effective elimination of cancer-affected cells necessitates a constant search for chemical compounds with specific biological activities. One alternative option is the transition metal complexes having potential as antitumor agents. Here, we present the current knowledge about the application of transition metal complexes bearing nickel(II), cobalt(II), copper(II), ruthenium(III), and ruthenium(IV). The cytotoxic properties of the above complexes causing apoptosis, autophagy, DNA damage, and cell cycle inhibition are described in this review.

Schiff Base Metal Complexes

Metal complexes synthesized from Schiff bases and furthermore Schiff bases are versatile in nature. Such types of compounds were prepared from the condensation of an amino compound with carbonyl compounds (aldehyde or ketone) during which the carbonyl group is replaced by an imine or azomethine group. Schiff bases and their derivatives are widely employed in industries, polymers, dyes and medicative and pharmaceutical fields and additionally exhibit biological activities like antibacterial, antifungal, anti-inflammatory, antimalarial, antiviral, and antipyretic properties. Many Schiff base metal complexes exhibit glorious catalytic activities in numerous mechanisms. Their several applications in homogenous and heterogeneous catalysis were according troughout last decade. Several Schiff base complexes were helpful for their application as catalysts in reactions involving at high temperatures because of the high thermal and moisture stabilities. This text totally based on literature review with examples of the most promising applied Schiff bases and their complexes in several areas, summarizing the applications of Schiff bases and their numerous derivatives and complexes.

Potential Antitumor

Cisplatin-based metal drugs have been widely used clinically as anticancer agents. However, these drugs also harm ordinary tissues because cisplatin kills cancer cells by attacking genomic DNA. Therefore, it has been shown that cisplatin-based metal drugs have some serious side effects that cannot be avoided. In order to replace the target site of genomic DNA, G-quadruplex nucleic acid is considered to be an alternative and attractive target for anticancer agents because G-quadruplex always folds into a parallel topology and is, therefore, more important than DNA. This review discussed the recent advancements in the rational design and the development of metal complexes containing anticancer drugs to interact and stabilize or cleave the G4 structure selectively. Further, we also highlighted the G4-interacting transition metal complexes, interacting modes, and their potentials to serve as anticancer drugs in the medical field. The significance of this survey lies in designing the metallodrugs from the most fundamental characteristic of electronic structural engineering to an increasingly reasonable dimension of bio-science.

Schiff bases, named after Hugo Schiff, are highly reactive organic compounds broadly used as pigments and dyes, catalysts, intermediates in organic synthesis, and polymer stabilizers. Lots of Schiff bases are described in the literature for various biological activities, including antimalarial, antibacterial, antifungal, anti-inflammatory, and antiviral. Schiff bases are also known for their ability to form complexes with several metals. Very often, complexes of Schiff bases with metals and Schiff bases alone have demonstrated interesting antitumor activity. Given the innumerable vastness of data regarding antitumor activity of all these compounds, we focused our attention on mono- and bis-Schiff bases alone as antitumor agents. We will highlight the most significant examples of compounds belonging to this class reported in the literature.

Unusual Structure

Schiff bases are versatile ligands which are synthesized from the condensation of primary amines with carbonyl groups. Synthesis of Schiff base transition metal complexes by using Schiff base as ligands appears to be fascinating in view of the possibility of obtaining coordination compounds of unusual structure and stability. These transition metal complexes have received exceptional consideration because of their active part in metalloenzymes and as biomimetic model compounds due to their closeness to natural proteins and enzymes. These compounds are very important in pharmaceutical fields because of their wide spectrum of biological activities. Most of them show biological activities including antibacterial, antifungal, antidiabetic, antitumor, antiproliferative, anticancer, herbicidal, and anti-inflammatory activities. The biological activity of the transition metal complexes derived from the Schiff base ligands has been widely studied. This review summarizes the importance, Scope and antimicrobial activities of Schiff base metal complexes.
