The present application describes modulators of chemokine receptor activity of formula (I):
or pharmaceutically acceptable salt forms thereof, useful for the prevention of asthma and other allergic diseases, as well as autoimmune pathologies such as rheumatoid arthritis and atherosclerosis, including methods of preparing and intermediates thereof.
The invention described herein relates to certain pyrimidinedione 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.
Disclosed are isolated, unnatural polypeptides containing cyclically-constrained β-amino acid residues and cyclically-constrained γ-amino acid residues. The compounds are unnatural and because they contain rotationally constrained residues that are not amenable to enzymatic degradation, the compounds are useful to probe protein-protein and other large molecule interactions.
