structure‐guided selection of fragments was used to identify three unexplored classes of humanDHODH inhibitor compounds: 4‐hydroxycoumarins, fenamicacids, and N‐(alkylcarbonyl)anthranilicacids. Structure‐guided selection of fragments targeting the inner subsite of the DHODH ubiquinone binding site made these findings possible with screening of fewer than 300 fragments in a DHODH assay. Fragments from the
Novel 3-substituted-4-aminoalkoxy-5,6-condensed ring-2-pyranones are disclosed as having utility as pharmacologically active compounds, in particular vasodilatory, hypotensive, anti-ischemic and anti-tussive activity. The compounds may be 3-phenyl-4-morpholinoalkoxy-coumarins. Administration may be by the oral or parenteral route. Intermediates useful in the production of these compounds are also disclosed.
