Abstract |
Given the therapeutic efficacy of fasudil hydrochloride (F) and dichloroacetate (DCA) on pulmonary arterial hypertension (PAH), a new salt fasudil dichloroacetate (FDCA) was designed, synthesized and biologically evaluated. FDCA exhibited comparable ROCK II inhibitory activity relative to fasudil hydrochloride, and suppressed the expression of TNF-α and IL-6 in both PDGF-BB and hypoxia-treated pulmonary arterial smooth muscle cells (PASMCs) and endothelial cells (PAECs). Significantly, FDCA lowered mean pulmonary artery pressure (mPAP) and right ventricular systolic pressure (RVSP), and decreased right ventricular hypertrophy (RVH) in monocrotaline (MCT)-induced PAH rats. Meanwhile, FDCA remarkably decreased pulmonary artery medial thickness (PAMT) and hyperplasia, restoring the elasticity of elastic fiber, reduced cardiac hypertrophy, and attenuated fibrosis of heart and lung. Collectively, FDCA exhibited triple activities of pulmonary vasodilation, vascular remodeling inhibition and RVH inhibition, suggesting that it may be a promising agent for PAH intervention.
