Two potentially complementary approaches to improve the anti-cancer strategy gene-directed enzyme prodrug therapy (GDEPT) are discovery of more efficient prodrug-activating enzymes, and development of more effective prodrugs. Here we demonstrate the utility of a flexible screening system based on the

NTR (nitroreductase NfsB from Escherichia coli) is a flavoprotein with broad substrate specificity, reducing nitroaromatics and quinones using either NADPH or NADH. One of its substrates is the prodrug CB1954 (5-[aziridin-1-yl]-2,4-dinitrobenzamide), which is converted into a cytotoxic agent; so NTR/CB1954

We report a phase I/II clinical trial in prostate cancer (PCa) using direct intraprostatic injection of a replication defective adenovirus vector (CTL102) encoding bacterial nitroreductase (NTR) in conjunction with systemic prodrug CB1954. One group of patients with localized PCa scheduled

The present work identifies a new mouse model of inductible acute glomerular injury leading to focal segmental glomerulonephritis. We take advantage of the suicide gene/prodrug nitroreductase/CB1954 combination, in which nitroreductase converts CB1954, a monofunctional alkylating agent, into its toxic form.
DNA damage and repair mechanism is vital for maintaining DNA integrity. Damage to cellular DNA is involved in mutagenesis, the development of cancer among others.
