Iron(III) and nickel(II) complexes bearing a thiosemicarbazone framework were synthesized by a one‐pot synthesis method. The structures were characterized by elemental analysis, IR, 1 H NMR, APCI Mass, conductivity, magnetic moment measurements. Molecular and crystal structures of the iron(III) complex were obtained from single‐crystal X‐ray diffraction. The findings showed that the metal atom adopts a slightly distorted square‐pyramidal coordination, with the four donor atoms of the thiosemicarbazone ligand defining the basal plane and a chloride atom occupying the apical position. In the crystal lattice, the structure is stabilized by intermolecular O─H···O and C─H···O interactions. The cytotoxic activity was studied by MTT assay, the expression levels of cytochrome P450 (CYP) enzymes by Western blot, and the lipophilicity (LogP) by using the shake‐flask method, another pharmacokinetic parameter. The findings showed that the IC 50 values decreased with the decrease of the LogP values of the substances. Cytochrome P450 expression levels were found specific for each compound and each cell line. As a result, the pharmacokinetic properties of the newly synthesized thiosemicarbazone compounds are crucial for oral administration and provide us with clues for prospective in vivo studies.
