Design, synthesis and RNase A inhibition activity of catechin and epicatechin and nucleobase chimeric molecules (vol 18, pg 5411, 2008)

Several novel catechin/epicatechin and nucleobase chimeric molecules 1–6 have been synthesized via azide-alkyne click chemistry. The structures of these hybrids have been confirmed by NMR and mass spectroscopic data. The synthesized molecules were tested for their RNase A inhibition activities. Gel-based assays showed inhibition in micromolar concentrations. The extent of inhibition was found to be dependent upon the nature of base as well as the configuration at C-3 position of catechin.
