INTRODUCTION: Pulmonary arterial hypertension (PAH) is a rare disorder associated
with abnormally elevated pulmonary pressures that, if untreated, leads to right
heart failure and premature death. The goal of drug development for PAH is to
develop effective therapies that halt, or ideally, reverse the obliterative
vasculopathy that results in vessel loss and obstruction of blood flow to the
lungs. AREAS COVERED: This review summarizes the current approach to candidate
discovery in PAH and discusses the currently available drug discovery methods
that should be implemented to prioritize targets and obtain a comprehensive
pharmacological profile of promising compounds with well-defined mechanisms.
EXPERT OPINION: To improve the successful identification of leading drug
candidates, it is necessary that traditional pre-clinical studies are combined
with drug screening strategies that maximize the characterization of biological
activity and identify relevant off-target effects that could hinder the clinical
efficacy of the compound when tested in human subjects. A successful drug
discovery strategy in PAH will require collaboration of clinician scientists with
medicinal chemists and pharmacologists who can identify compounds with an
adequate safety profile and biological activity against relevant disease
mechanisms.
