Competition-based, quantitative chemical proteomics in breast cancer cells identifies new target profiles for sulforaphane

Chem Commun (Camb). 2017 May 4;53(37):5182-5185. doi: 10.1039/c6cc08797c.

Abstract

Sulforaphane is a small molecule isothiocyanate which exhibits anticancer potential, yet its biological targets remain poorly understood. Here we employ a competition-based chemical proteomics strategy to profile sulforaphane's targets and identify over 500 targets along with their relative affinities. These targets provide a new set of mediators for sulforaphane's bioactivity, and aid understanding of its complex mode of action.
