  • Publication number: 20040053323
    Abstract: Methods of screening for iNOS activity inhibitors are provided using the binding activity of candidate compounds towards the iNOS monomer (or a mutant thereof) as an index. Dimerization of iNOS is the final step in the acquisition of iNOS enzyme activity. The screening methods according to this invention enable quick screening of iNOS inhibitory compounds that have excellent specificity and rapid action properties through simple manipulations.
