Objective:
To investigate the experimental therapeutic effects of iptakalim hydrochloride (Ipt) on renoprotection in spontaneously hypertensive rats.
Methods:
30 SHR were treated ig with Ipt 1, 3, 9 mg.kg(-1).d(-1), benazepril 3 mg.kg(-1).d(-1) once a day for 12 weeks. Age-matched WKY rats were used as normal control. The blood pressure, heart rates, proteinuria were assessed, and renal tissues were examined by light microscopy. The levels of blood and renal tissue ET-1 and TGF-beta1 were detected respectively by radioimmunoanalysis and enzyme linked immune absorption assay (ELISA).
Results:
During 12 weeks experimental period, the systolic blood pressure (SBP) and heart rates (HR) of the untreated SHR were increased progressively. Ipt (3, 9 mg.kg(-1).d(-1)) could decrease effectively and inhibit the increasing tendency of HR. In addition, Ipt (1, 3, 9 mg.kg(-1).d(-1)) reduced urinary proteinuria, alleviated obviously the small vascular remodeling of renal and decreased the levels blood and renal ET-1 and TGF-beta1. Ipt (3, 9 mg.kg(-1).d(-1)) alleviated obviously the small vascular remodeling of renal compared with Ipt (1 mg.kg(-1).d(-1)).
Conclusions:
Ipt (1, 3, 9 mg.kg(-1).d(-1)) decreased SBP and protected the kidney of SHR. The renoprotection of Ipt may be involved in inhibiting of blood and renal tissue ET-1 and TGF-beta1.

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...
