The design and synthesis of two closely related series of prostacyclin receptor agonist compounds that showed excellent human IP receptor potency and efficacy is described. Compounds from this series showed in vivo activity after SC dosing in the monocrotaline model of PAH in rat.
A new class of divalent thrombin inhibitors is described that contains an alpha-keto-amide transition-state mimetic linking an active site binding group and a group that binds to the fibrinogen-binding exosite. The X-ray crystallographic structure of the most potent member of this new class, CVS995, shows many features in common with other divalent thrombin(More)
A series of pyrimidine analogues derived from ATC0175 were potent antagonists of human MCH-R1 in vitro. Significantly improved receptor selectivity was achieved with several analogues from this series, but no improvement in brain partitioning was noted. One example from this series was shown to inhibit food intake and decrease body weight in a chronic(More)
The design and synthesis of a new series of potent non-prostanoid IP receptor agonists that showed oral efficacy in the rat monocrotaline model of pulmonary arterial hypertension (PAH) are described. Detailed profiling of a number of analogues resulted in the identification of 5c (ralinepag) that has good selectivity in both binding and functional assays(More)
