1,2,4-Triazolo-[1,5-a]pyridine HIF Prolylhydroxylase Domain-1 (PHD-1) Inhibitors With a Novel Monodentate Binding Interaction
摘要:
Herein we describe the identification of 4-{[1,2,4]triazolo[1,5-a]pyridin-5-yl}benzonitrile-based inhibitors of the hypoxia-inducible factor prolylhydroxylase domain-1 (PHD-1) enzyme. These inhibitors were shown to possess a novel binding mode by X-ray crystallography, in which the triazolo N1 atom coordinates in a hitherto unreported monodentate interaction with the active site Fe2+ ion, while the benzonitrile group accepts a hydrogen -bonding interaction from the side chain residue of Asn315. Further optimization led to potent PHD-1 inhibitors with good physicochemical and pharmacokinetic properties.

A series of imidazo-fused heterocycles substituted with an aryloxy)alkylamine side chain were prepared as modifications to butoprozine (I) and found to possess calcium channel blocking activity similar in potency to that of bepridil in trachea smooth muscle and similar to that of verapamil in nitrendipine binding affinity in rabbit cardiac muscle. Of the various imidazo-fused heterocycles prepared, the imidazo[1,2-a]pyridines were also found to be potent local anesthetic agents. While most compounds in this series were equipotent to lidocaine in our initial screen, compounds 2 and 35 showed local anesthetic activity approximately 100 times more potent than lidocaine in our preliminary assays. These compounds represent a novel structural class of local anesthetic agents, and compound 2 is under further investigation.
