The nature of DNA containing the deoxyribosyl derivative of 5-nitroindole has been investigated. 5-Nitroindole has been shown to give good stability when present in duplexes opposite natural bases, with only slightly reduced melting temperatures. However, enhanced stability occurs when it
5-Nitroindole (NI), a mutagenic nitroarene, was assayed for cytotoxic effects on rat hepatocytes. After incubation with 25-100 microM NI, the adenylate energy charge of the hepatocytes decreased significantly as a result of the decrease in ATP and the increase in
Most models accounting for the efficiency and fidelity of DNA polymerization invoke the use of either hydrogen bonding contacts or complementarity of shape and size between the formed base pair. This report evaluates these mechanisms by quantifying the ability of

Hydrophobic base analogues (HBAs) have shown great promise for the expansion of the chemical and coding potential of nucleic acids but are generally poor polymerase substrates. While extensive synthetic efforts have yielded examples of HBAs with favorable substrate properties, their
3-Nitropyrrole and 5-nitroindole have been assessed as universal bases in primers for dideoxy DNA sequencing and in the polymerase chain reaction (PCR). In contrast to a previous report, we have found that the introduction of more than one 3-nitropyrrole residue
