170 results about "Glutathione S-transferase" patented technology

Glutathione S-transferases (GSTs), previously known as ligandins, comprise a family of eukaryotic and prokaryotic phase II metabolic isozymes best known for their ability to catalyze the conjugation of the reduced form of glutathione (GSH) to xenobiotic substrates for the purpose of detoxification. The GST family consists of three superfamilies: the cytosolic, mitochondrial, and microsomal—also known as MAPEG—proteins. Members of the GST superfamily are extremely diverse in amino acid sequence, and a large fraction of the sequences deposited in public databases are of unknown function. The Enzyme Function Initiative (EFI) is using GSTs as a model superfamily to identify new GST functions.

Vivo use of glutathione s-transferase activated nitric oxide donors

The present invention provides for a method of simultaneously treating both cancer and the Multidrug Resistance Phenotype via inhibition of cellular thiols, such as Glutathione S-Transferase (GST). This enzyme is overproduced in leukemia and solid tumor cells and is one of the main pathways involved in the Multidrug Resistance phenotype. The treatment provides for the administration of a chemically inert pro-drug, designed to be a specific substrate for the GST enzyme that, once cleaved, liberates the bioactive toxin Nitric Oxide (NO) intracellularly at the site of a malignant growth. NO then acts to inhibit the growth of the malignant cells and to induce cellular differentiation and apoptosis therein, effectively treating an existing cancerous condition. Additionally, once NO is liberated from the pro-drug, the remaining structure acts to inhibit further GST activity, providing a treatment for the Multidrug Resistant phenotype.
