The invention described herein relates to certain pyridazinedione N-substituted glycine derivatives of formula (I) which are antagonists of HIF prolyl hydroxylases and are useful for treating diseases benefiting from the inhibition of this enzyme, anemia being one example.
Claims10
A compound which is N-{[2-[(4-bromo-2-fluorophenyl)methyl]-5-hydroxy-6-(1-methylethyl)-3-oxo-2,3-dihydro-4-pyridazinyl]carbonyl}glycine or a salt thereof.
A method for treating anemia in a mammal, which method comprises administering an effective amount of N-{[2-[(4-bromo-2-fluorophenyl)methyl]-5-hydroxy-6-(1-methylethyl)-3-oxo-2,3-dihydro-4-pyridazinyl]carbonyl}glycine or a salt thereof to a mammal suffering from anemia which can be treated by inhibiting HIF prolyl hydroxylases.
