“…However the acetato-bridged derivatives due to their typical open book shape do not show mesomorphism, except the cyano and fluoro substituted complexes, which exhibit a monotropic Smectic A mesophase. 132 The melting points decrease in the order NO2 > CN > CH3 > Cl > F for the acetate complexes, and F > NO2 > Cl > CH3 > CN for the chloro-bridged derivatives.…”

“…(E)-2-hydroxy-4-(phenyldiazenyl)benzaldehyde (hpdb in Figure 3) was synthesized by following the reported methodologies [36,37]. Measures of 1.0 g of aniline and 5 mL of a 2:1 mixture of concentrated HCl and water were added to a 100 mL beaker and the resulting solution was stirred at room temperature.…”

The azo-azomethine imines, R1-N=N-R2-CH=N-R3, are a class of active pharmacological ligands that have been prominent antifungal, antibacterial, and antitumor agents. In this study, four new azo-azomethines, R1 = Ph, R2 = phenol, and R3 = pyrazol-Ph-R’ (R = H or NO2), have been synthesized, structurally characterized using X-ray, IR, NMR and UV–Vis techniques, and their antifungal activity evaluated against certified strains of Candida albicans and Cryptococcus neoformans. The antifungal tests revealed a high to moderate inhibitory activity towards both strains, which is regulated as a function of both the presence and the location of the nitro group in the aromatic ring of the series. These biological assays were further complemented with molecular docking studies against three different molecular targets from each fungus strain. Molecular dynamics simulations and binding free energy calculations were performed on the two best molecular docking results for each fungus strain. Better affinity for active sites for nitro compounds at the “meta” and “para” positions was found, making them promising building blocks for the development of new Schiff bases with high antifungal activity.
