Open Access research with a European policy impact...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the European Policies Research Centre (EPRC).

EPRC is a leading institute in Europe for comparative research on public policy, with a particular focus on regional development policies. Spanning 30 European countries, EPRC research programmes have a strong emphasis on applied research and knowledge exchange, including the provision of policy advice to EU institutions and national and sub-national government authorities throughout Europe.

Abstract

It has been shown that 6-acetyl-7,7-dimethyl-5,6,7,8-tetrahydropteridin-4(3H)-one can act as a competent cofactor for the production of nitric oxide by neuronal nitric oxide synthase (nNOS). More information was sought on the structural features that could contribute to strong binding within the enzyme whilst maintaining a fast electron transfer rate. This study was concerned with expansion at the C2-position of the pteridine scaffold. The evidence suggests that expansion at the C2-position had a deleterious effect with respect to Km and as a consequence electron transfer rate. Unexpectedly, several lines of evidence suggested that a methyl substituent on nitrogen at C2 reduced the electron density in the pyrimidine and dihydropterin rings.
