Abstract:
Niacin is an effective drug for raising HDL cholesterol and reducing coronary risks, but patients show low compliance with treatment due to severe facial flushing upon taking the drug. A series of bicyclic pyrazole carboxylic acids were synthesized and tested for their ability to activate the niacin receptor. One analog, 23, showed improved potency and lacked flushing at doses that effectively altered the lipid profile of rats.

Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...
