Synthesis and Spectroscopic Characterization of Schiff Base Metal Complexes, Biological Activity, and Molecular Docking Studies.

New cobalt(II), copper(II), and zinc(II) Schiff metal complexes were synthesized by the condensation reaction of 4-nitrobenzene-1,2-diamine with 3-4-(diethylamino)-2-hydroxybenzaldehyde. Fourier transform infrared, nuclear magnetic resonance, ultraviolet-visible, electron paramagnetic resonance, and high-resolution electrospray ionization mass spectrometry and powder X-ray diffraction were used to characterize the synthesized HL and its metal complexes. Conductance measurements, magnetic moment estimation, and metal estimation have all been determined and discussed.

Prospective in vitro A431 cell line anticancer efficacy of zirconia nanoflakes derived from Enicostemma littorale aqueous extract.

Biomedical applications of zirconia nanomaterials were limited in biological systems. In this research, 8-15 nm size zirconia nanoflakes (ZrNFs) were fabricated and their nature, morphology, and biocompatibility were evaluated. The synthesis was carried out using Enicostemma littorale plant extract as an effective reducing and capping agent.
