Development of new treatment strategies and chemotherapeutic agents is urgently needed to combat the growing multidrug resistant species of Candida. In this direction, a new series of Cu (II), Co (II), Ni (II) and Zn (II) heteroleptic complexes were synthesized, characterized and evaluated for antifungal activity. Based on spectral characterization and physical measurements, an octahedral geometry was assigned to [Co(L1)(L2)ClH₂O] (C2), [Ni(L1)(L2)ClH₂O] (C3), [Zn(L1)(L2)ClH₂O] (C4) complexes, while a distorted octahedral geometry was assigned to [Cu(L1)(L2)ClH₂O] (C1) complex. All the synthesized compounds were tested for antifungal activity against 11 Candida albicans isolates, including fluconazole (FLC)‐resistant isolates, by determining minimum inhibitory concentrations (MIC) and minimum fungicidal concentrations (MFC), following CLSI guidelines. The mechanism of their antifungal activity was …
