Nitric oxide synthases (NOSs) are flavohemeproteins that catalyze the oxidation of L-arginine to L-citrulline with formation of the signaling molecule nitric oxide (NO). In addition to their fundamental role in NO biosynthesis, NOSs are also involved in the formation of

We have completed a phase I/II suicide gene therapy clinical trial in patients with prostate cancer, using an E1/E3-deleted replication-deficient adenovirus (CTL102) encoding the bacterial nitroreductase enzyme in combination with prodrug CB1954. This study has provided an opportunity to monitor

Prodrug activation gene therapy is a developing approach to cancer treatment, whereby prodrug-activating enzymes are expressed in tumour cells. After administration of a non-toxic prodrug, its conversion to cytotoxic metabolites directly kills tumour cells expressing the activating enzyme, whereas the

DNA-damaging agents are widely used in cancer treatment despite their lack of tumor specificity. Human NQO2 (quinone oxidoreductase-2) is an atypical oxidoreductase because no endogenous electron donor has been identified to date. The enzyme converts CB1954 [5-(aziridin-1-yl)-2,4-dinitrobenzamide], in the presence

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
