  New classes of CRTH2 antagonists, the pyridazine linker containing indole acetic acids, are described. The initial hit 1 had good potency but poor permeability, metabolic stability, and PK. Initial optimization led to compounds of type 2 with low oxidative metabolism but poor oral bioavailability. Poor permeability was identified as a liability for these compounds. Addition of a linker between the indole and diazine moieties afforded a series with good potency, low rates of metabolism, moderate permeability, and good oral bioavailability in rodents, 32 was identified as the development track candidate. It was potent in cell based, binding, and whole blood assays and exhibited good PK profile. It was efficacious in mouse models of contact hypersensitivity (1 mg/kg b.i.d.) and house dust (20 mg/kg q.d.) when dosed orally. In sheep asthma, administration at 1 mg/kg iv completely blocked the LAR and AHR and attenuated the EAR phase.
