A mononuclear N,N,N,O donor schiff base Cu(II) complex inhibits bacterial biofilm formation and promotes apoptosis and cell cycle arrest in prostate cancer cells.

In this work, we report a distorted square pyramidal mononuclear copper(II) complex [Cu(L)(NCS)] (1) which was obtained by the reaction of the aqueous solution of ammonium thiocyanate to a methanolic solution of copper nitrate trihydrate and corresponding Schiff-base ligands. Schiff bases, HL (CHNO) act as a tetradentate Schiff base, derived from 1:1 condensation of o-hydroxyacetophenone and diethylenetriamine. The synthesized complex has been successfully characterized based on elemental analysis and Infrared (IR) spectroscopy.

Development of Copper Nanoparticle Conjugated Chitosan Microparticle as a Stable Source of 2nm Copper Nanoparticle Effective against Methicillin- resistant .

Background: Copper nanoparticle (CuNP) has well-established antimicrobial activity. Instability in an aqueous medium due to aggregation into larger particles, conversion into metal ions, and oxidation into metal oxides are the major limitations of its practical use against bacterial infections.

Objective: Development of CuNP Conjugated Chitosan Microparticles as a reservoir that will release CuNP effective against notorious bacteria like Methicillin-resistant Staphylococcus aureus.
