Abstract: This invention provides aryl and heteroaryl compounds of Formula (I) as described herein, and methods of their preparation. Also provided are pharmaceutical compositions made with the compounds of Formula (I) and methods for making such compositions. The compounds of Formula (I) may activate an erythropoietin receptor and thus, may be useful to induce red blood cell production. The compounds of Formula (I) and compositions including compounds of Formula (I) may be useful in a variety of applications including the management, treatment and/or control of diseases caused at least in part by deficient (or inefficient) EPO production relative to hemoglobin level.
