In an effort to synthesize more effective non-nucleoside reverse transcriptase inhibitors (NNRTIs) against the HIV-1 infection, a new series of novel 4-nitroimidazole derivatives combined with 5-hydroxy-4-pyridinone moiety were designed by molecular docking studies, prepared and characterized by spectroscopic techniques. All the synthesized compounds were in vitro evaluated for their inhibitory effect against the HIV-1 replication in the MT-4 cells. Results showed that none of these synthesized compounds displayed any specific anti HIV-1 activity. Surprisingly, these compounds showed high cytotoxicity against MT-4 cells with low selectivity index (50 = 1.3 μM and EC50 = 1.8 μM respectively).

A series of compounds containing 2-substituted imidazoles has been synthesized from imidazole and tested for its biological activity against human African trypanosomiasis (HAT). The 2-substituted 5-nitroimidazoles such as fexinidazole (7a) and 1-[4-(1-methyl-5-nitro-1H-imidazol-2-ylmethoxy)-pyridin-2- yl-piperazine (9e) exhibited potent activity against T. brucei in vitro with low cytotoxicity and good solubility. The presence of the NO2 group at the 5-position of the imidazole ring in 2-substituted imidazoles is the crucial factor to inhibit T. brucei.

Peroxynitrite reacts with 2′,3′,5′-tri-O-acetyl-guanosine to yield a novel compound identified as 1-(2,3,5-tri-O-acetyl-β-D-erythro-pentofuranosyl) -5-guanidino-4-nitroimidazole (6). This characterization was achieved using a combination of UV/vis spectroscopy and ESI-MS. Additionally, 1 -(β-D-erythro-pentofuranosyl) 5-guanidino-4-nitroimidazole (6a) was synthesized by an independent route, characterized by UV/vis spectroscopy, ESI-MS, and 1H- and 13C NMR, and shown to be identical to deacetylated 6. This product is extremely stable in aqueous solution at both pH extremes and is formed in significant yields. These characteristics suggest that this lesion may be useful as a specific biomarker of peroxynitrite-induced DNA damage. We also observed formation of 2′,3′,5′-tri-O-acetyl-8-nitroguanosine (2′,3′,5′-tri-O-acetyl-8-NO2Guo), 2-amino-5-[(2,3,5 tri-O-acetyl-β-D-erythro-pentofuranosyl)amino]-4H-imidazol-4-one (2′,3′,5′-tri-O-acetyl-Iz), and the peroxy-nitrite-induced oxidation products of 2′,3′,5′-tri-O-acetyl-8-oxoGuo. The formation of 6 and 2′,3′,5′-tri-O-acetyl-8-NO2Guo was rationalized by a mechanism invoking formation of the guanine radical.
