Abstract
|
|
|
In certain neurodegenerative diseases damaging levels of nitric oxide (NO) are
produced by neuronal nitric oxide synthase (nNOS). It, therefore, is important
to develop inhibitors selective for nNOS that do not interfere with other NOS
isoforms, especially endothelial NOS (eNOS), which is critical for proper
functioning of the cardiovascular system. While we have been successful in
developing potent and isoform-selective inhibitors, such as lead compounds 1 and
2, the ease of synthesis and bioavailability have been problematic. Here we
describe a new series of compounds including crystal structures of NOS-inhibitor
complexes that integrate the advantages of easy synthesis and good biological
properties compared to the lead compounds. These results provide the basis for
additional structure-activity relationship (SAR) studies to guide further
improvement of isozyme selective inhibitors.
