Several new dioxomolybdenum(VI) complexes containing tridentate ONS donor ligand (H2L) derived from pyridoxal and S-benzyldithiocarbazate have been synthesized by refluxing MoO2(acac)2 with Schiff base ligand and Lewis base (B) (where, B = pyridine, γ-picoline, 1-methylimidazole, tetrahydrofuran) in 1:1:1.5 M proportions in methanol. The complexes having general formula MoO2LB (1–4) are thoroughly characterized by elemental analyses and various spectroscopic techniques (IR, 1H NMR, UV-Vis and mass spectra). The structures of the complexes have been optimized by D. Functional Theory (DFT) calculations The hexa coordinated metal center possesses a distorted octahedral geometry in all the complexes. The redox behavior of the complexes is studied by cyclic voltammetry. The oxo-transfer reactivity of the MoO2LB complexes with PPh3 has also been examined The interactions of the complexes with Bovine Serum Albumin (BSA) protein are investigated spectroscopically by absorption, fluorescence titration and fluorescence life time measurements. The values of the Stern-Volmer constant (KSV), binding constant (Kb) and number of binding sites (n) are determined which indicates significant binding with BSA protein. Fluorescence spectral change also indicates efficient FRET from the protein to ligand and complexes. Mol. docking studies have also been carried out to understand the binding modes and interaction patterns of the dioxomolybdenum(VI) complexes with BSA. This study involved multiple reactions and reactants, such as 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5Name: 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride).
3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride (cas: 65-22-5) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Name: 3-Hydroxy-5-(hydroxymethyl)-2-methylisonicotinaldehyde hydrochloride
