“…On the contrary condensation of 1,2‐diaminobenzene with thiophene‐2‐carboxaldehyde produced a different type of azomethine, which was used as ligand in the preparation of complexes 242 (Figure 29) of several transition metals, along with phenantroline as coligand. [ 220 ] Evaluation by the disc diffusion method showed that the zinc and nickel complexes had only moderate activity against all bacterial strains used in the study, while the cobalt and copper complexes had significant antibacterial activity. The diameters of the inhibition zone determined for complexes 242 (M = Cu) at various concentrations were consistently greater than the diameters of the inhibition zone of streptomycin for all the bacterial strains.…”

Thiophene, as a member of the group of five-membered heterocycles containing one heteroatom, is one of the simplest heterocyclic systems. Many synthetic strategies allow the accurate positioning of various functionalities onto the thiophene ring. This review provides a comprehensive, systematic and detailed account of the developments in the field of antimicrobial compounds featuring at least one thiophene ring in their structure, over the last decade.

“…The Cu(II) complex in comparison to all other complexes, is more toxic and effective towards the microbes-S. aureus, B. species, and K. pneumonia with inhibitory zone values of 31.3, 25.7 and 19.7 mm respectively, and to the standard (streptomycin) with respective inhibition values of 22.0, 22.0 and 24.0 mm. Result of this kind, in which test compounds have greater antibacterial efficacy than the standard-streptomycin has been reported [36][37][38].…”

A series of some 3d (Mn, Fe, Co, Ni, Cu and Zn) metal(II) complexes of mixed-ligands-N,N′-dimethyldithiocarbamate (SDTC) and 4,4,4-trifluoro-1-(2-naphthyl)-1,3-butanedione (TFNB) have been synthesized and presented for antioxidant, antibacterial and antifungal studies. The complexes were examined for their in-vitro antioxidant potentials by employing ferrous ion chelating and DPPH scavenging methods, while the in-vitro antimicrobial screening of the unbound ligands and their mixed metal(II) complexes against bacteria-Staphylococcus aureus, Bacillus cereus (Gram (+ve)), Klebsiella pneumoniae, Pseudomonas aeruginosa and Escherichia coli (Gram (−ve)), and fungi-Aspergillus niger, Aspergillus flavous, Fusarium species using agar and disc diffusion methods respectively. The studies revealed that Co(II) complex had the highest antioxidant potential with the percentage scavenging inhibition of 75.04%. The antimicrobial screening of the complexes against the bacterial microbes showed that Cu(II) complex had the best activity with inhibitory zone range of 19.7-31.3 mm; while Fe(II) complex possesses highest fungicidal activities within the inhibitory zone range of 28.7-38.0 mm; compared to other complexes against the fungi strains. Molecular docking approach indicated that Cu(II) complex had higher binding affinity with π-sulphur and Van der Waals interactions.
