It has been reasoned out that induction of greater quantities of Reactive oxygen (ROS) with in the tumor cells is a cancer treatment strategy known as Chemodynamic therapy (CDT). Depending on the administration of Fenton reaction facilitators like Fe2+, CDT benefits from the fact that over generated ROS amongst the tumor microenvironment. Production of a peptides- H2S donor conjugate (PHDC) which was complexed with Fe2+ known as AAN-PTC- Fe2+ was achieved by Zhu., et al. This AAN-tripeptide was particularly cleaved by legumain, an enzyme which was over expressed in glioma cells for liberation of carbonyl Sulfide (COS). Whereas COS hydrolysis by enzyme carbonic anhydrase (CA) which generated H2S, a hampering agent of catalase (CAT), an enzyme which leads to detoxification of H2O2. Fe2+ in combination with H2S escalated intracellular ROS quantities as well as diminished viability in C6 glioma cells in contrast to controls having absence of either Fe2+, AAN sequence or capacity of production of H2S. AAN-PTC- Fe2+ worked better compared to temozolomide whereas demonstrating no cytotoxicity against cardiomyocytes. Hence this study illustrated an H2S-augmented, enzyme responding manifesto regarding synergistic cancer treatment.
