  Discovery of Isoquinolinone Indole Acetic Acids as Antagonists of Chemoattractant Receptor Homologous Molecule Expressed on Th2 Cells (CRTH2) for the Treatment of Allergic Inflammatory Diseases

  摘要：

  Previously we reported the discovery of CRA-898 (1), a diazine indole acetic acid containing CRTH2 antagonist. This compound had good in vitro and in vivo potency, low rates of metabolism, moderate permeability, and good oral bioavailability in rodents. However, it showed low oral exposure in nonrodent safety species (dogs and monkeys). In the current paper, we wish to report our efforts to understand and improve the poor PK in nonrodents and development of a new isoquinolinone subseries that led to identification of a new development candidate, CRA-680 (44). This compound was efficacious in both a house dust mouse model of allergic lung inflammation (40 mg/kg qd) as well as a guinea pig allergen challenge model of lung inflammation (20 mg/kg bid).
