However, the preparation of a p-nitroanilide is not easy, in part due to the low nucleophilicity of the amino group of p-nitroaniline. A facile preparation of p-nitroanilide analog by the solid-phase method was investigated. 5-Amino-2-nitrobenzoic acid (Anb5,2) was used instead of p-nitroaniline (pNA) for preparation of p-nitroanilide analogs.

· A nucleoside is a molecule with a pentose sugar linked to a nitrogenous base or glycosylamines. A nucleoside can also be defined as a nucleotide without a phosphate group attached to it. The nucleosides present in DNA contain a 2` – deoxy – D- ribose sugar and nucleosides in RNA contain D-ribose sugar. The main difference is seen at the ...
