Reduced glutathione or simply glutathione (γ-glutamylcysteinylglycine; GSH) is found in the cytosol of most cells of the body. GSH in the epithelial lining fluid (ELF) of the lower respiratory ...

It responds to elevated glutathione (GSH) levels, a molecule abundant in tumour cells. Upon encountering high GSH levels, the hydrogel triggers a controlled drug release directly into the tumour ...

Carrier-free nano-prodrugs (NPDs) were developed for selective drug release in cancer cells using stimulus-responsive systems: esterases, reactive oxygen species (ROS), and glutathione (GSH).
