nucleotides, despite the fact that their biological effects are closely linked to their chemical properties. To this end, a selection of chemical reactions have been performed on 8‐nitroguanine nucleosides and oligodeoxynucleotides. Reactions with alkylating reagents reveal how the 8‐nitro substituent affects the reactivity of the purine ring, by significantly decreasing the reactivity of the N2 position

reaction product of nitric oxide and superoxide anion, and a powerful oxidant, was found to nitrate as well as oxidize adenine, guanine, and xanthine nucleosides. A highly sensitive reverse-phase HPLC method with a dual-mode electrochemical detector, which reduces the nitro product at the first electrode and detects the reduced product by oxidation at the second electrode, was applied to detect femtomole
Azido- and fluoro- derivatives of 8-nitroguanosine were developed, and will contribute to the exploration of proteinS-guanylation by endogenous nitrated nucleosides.

The present invention provides a broad-spectrum, long-lasting, and non-toxic combination of synthetic immunostimulatory agents, which are useful for activating the immune system of a mammal and treating diseases such as cancer and autoimmune disease. These agents include TLR-ligands and ligand analogs which induce interferon production, in combination with inhibitors of inosine monophosphate dehydrogenase (IMPDH), that further enhance the induction of interferon production.
