A novel pyrazolone complex P-FAH-Cu-bpy induces death of Escherichia coli and Staphylococcus aureus by disrupting cell structure and blocking energy.

A novel pyrazolone-based copper complex [Cu(L)(bpy)]∙CH3OH (P-FAH-Cu-bpy) was synthesized and previously characterized to have antitumor properties. This study aimed to investigate its antibacterial properties and action modes against Escherichia coli and Staphylococcus aureus. By agar diffusion assay, P-FAH-Cu-bpy showed strong antibacterial activity against E.

Novel Copper(II) Complex with a 4-Acylpyrazolone Derivative and Coligand Induce Apoptosis in Liver Cancer Cells.

A novel pyrazolone-based copper complex [CuL(phen)(CHOH)][CuL(phen)]·CHCHOH·CHOH (P-FAH-Cu-phen) was synthesized and characterized. The asymmetric structural unit of P-FAH-Cu-phen was composed of two independent complex units [CuL(phen)(CHOH)] and [CuL(phen)]:Cu1 center with six coordination mode and Cu2 center with five coordination mode. The growth of BEL-7404 cells and H22 cells was significantly inhibited by P-FAH-Cu-phen with IC values of 1.
