Herein the authors 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 crystallog., 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 Asn 315. Further optimization led to potent PHD-1 inhibitors with good physicochem. and pharmacokinetic properties. In the experiment, the researchers used many compounds, for example, 4-Bromo-2-fluoro-3-methylbenzonitrile (cas: 1114546-30-3SDS of cas: 1114546-30-3).
4-Bromo-2-fluoro-3-methylbenzonitrile (cas: 1114546-30-3) belongs to nitriles. Trimerization of aromatic nitriles requires harsh reaction conditions, high temperatures, long reaction times, and pressure. In addition, Nitriles can react with alkynes, which leads to an increase in carbon chain length (carbocyanation).SDS of cas: 1114546-30-3
