A copper(II) complex with a thioether and ether containing azophenol ligand: Synthesis, spectra, X-ray structure and DFT computations
摘要:
A new ONSO donor azophenol ligand (HL) having thioether-S and ether-O atoms has been synthesized and characterized by various spectroscopic techniques. The hydrazoketo and azoenol equilibrium of the ligand has been studied by a theoretical study. The copper(II) complex, having the formula [Cu(L)(H2O)](ClO4), has been synthesized and structurally characterized by a single crystal X-ray study. The electronic structures of HL and the Cu(II) complex have been interpreted by OFT studies. The electronic spectra of the compounds have been interpreted by TDDFT calculations.

The severe acute respiratory syndrome (SARS) coronavirus 3CL protease is an attractive target for the development of anti-SARS drugs. In this paper, cinanserin (1) analogs were synthesized and tested for the inhibitory activities against SARS-coronavirus (CoV) 3CL protease by fluorescence resonance energy transfer (FRET) assay. Four analogs show significant activities, especially compound 26 with an IC50 of 1.06 μM.
