Cooperative enhancement of antibacterial activity of sanguinarine drug through p-sulfonatocalix[6]arene functionalized silver nanoparticles

Chem Commun (Camb). 2019 Nov 26;55(95):14275-14278. doi: 10.1039/c9cc07378g.

Abstract

The amelioration of antibacterial efficacy along with the reduced minimum inhibitory concentration (MIC) of sanguinarine (SGR) drug have been demonstrated through the uptake of SGR by p-sulfonatocalix[6]arene functionalized silver nanoparticles. The large upward pKa shift and enhanced stability of SGR resulting from the favorable supra-nanomolecular strategy are deciphered into an improved antibacterial drug against different pathogenic micro-organisms including multi drug resistant bacteria.
