Abstract: There is a method of treating or preventing pulmonary arterial hypertension (PAH) or associated pulmonary arterial hypertension (APAH) in a patient. The method has the step of systemically administering to the patient a therapeutically effective amount of one or more compounds: (S)-ethyl 8-(2-amino-6-((R)-1-(5-chloro-[1,1?-biphenyl]-2-yl)-2,2,2-trifluoroethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-3-carboxylate or a pharmaceutically acceptable salt thereof, or (S)-8-(2-amino-6-((R)-1-(5-chloro-[1,1?-biphenyl]-2-yl)-2,2,2-trifluoroeth-oxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-3-carboxylic acid or a pharmaceutically acceptable salt thereof, or a combination of the foregoing. There is also a method of treating or preventing PAH or APAH in a patient by systemically administering a therapeutically effective amount of a THP1 inhibitor from about 1 mg/kg/day to about 50 mg/kg/day. There is a method for treating PAH or APAH in a patient with a single daily dose.

Abstract: This invention provides, among other things, novel compounds useful for treating protozoal infections, pharmaceutical compositions containing such compounds, as well as combinations of these compounds with at least one additional therapeutically effective agent.
