- 1,2,4-Triazolo-[1,5-a]pyridine HIF Prolylhydroxylase Domain-1 (PHD-1) Inhibitors with a Novel Monodentate Binding Interaction
-
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.

- BICYCLIC COMPOUND AND PHARMACEUTICAL USE THEREOF
-
The present invention provides a compound represented by the formula wherein R1 is a hydrocarbon group optionally having substituent(s), amino optionally having substituent(s), hydroxy optionally having a substituent or a heterocyclic group optionally having substituent(s); R2 is a hydrogen atom or a hydrocarbon group optionally having substituent(s); Xa and Xb are each C, N, O or S; Xc and Xd are each C or N; m is 0-2; n is 1-3; ring A is a 5-membered ring optionally having substituent(s); ring B is a 6-membered ring optionally having substituent(s); and ring C is a 3- to 5-membered ring optionally having substituent(s), provided that when Xa, Xc and Xd are each C, then Xb is N or S, or a salt thereof, which is useful as an agent for the prophylaxis or treatment of a disease relating to an action of melatonin, and the like.
