The increased awareness regarding the quality and safety of poultry products and related health properties, in addition to the prohibition of antibiotic growth promoters from the European Union markets have raised attention of producers to plant-based feed additives as unconventional alternatives. Phytogenic feed supplements, such as spices, intact herbs and their extracts, prebiotics, probiotics, and essential oils are the conventional alternatives of antibiotic growth promoters in poultry production sector (Abd

An organometallic azomethine ferrocenyl ligand (FCAP) and its transition metal complexes ([M (FCAP)2], where M = VO2+, Mn2+ cations, and [M (FCAP) (CH3COO− or NO3−)], where M = Zn2+ and Pd2+ cations) were prepared. Their structures were confirmed via various spectral and physicochemical studies performed. The crystallinity of the investigated metal chelates was confirmed by X‐ray diffraction data. The spectral data of the FCAP azomethine ligand and its metal chelates were explained concerning the structural changes due to complex formation. From the electronic spectra and the magnetic moments, the information about geometric structures can be concluded. The activation thermodynamic parameters of the thermal degradation for FCAP complexes were calculated utilizing the method of Coats–Redfern. in vitro antimicrobial, anticancer, and antioxidant activities of FCAP azomethine ligand and its complexes were screened. All the investigated metal chelates exhibited superiority on the free FCAP ligand in successful treatment. Moreover, the binding nature of the investigated complexes with calf thymus DNA (ctDNA) was examined by various methods such as spectrophotometry, viscosity, and, gel electrophoresis. Their binding feature to ctDNA was proposed to be electrostatic, intercalation, or replacement mode. Furthermore, molecular docking inspection has been conducted to clarify the nature of the binding and binding affinity of protein synthesized compounds (PDB:3hb5).
