Effects of CL 115,347, (+/-)-15-deoxy-16-hydroxy-16-vinyl-PGE2 methyl ester, on cardiovascular responses and plasma catecholamines in pithed stroke-prone spontaneously hypertensive rats during sympathetic stimulation.
    Prostaglandins, 1984, Volume: 27, Issue:2

    The effect of CL 115,347, a topically active antihypertensive PGE2 analog, and PGE2 on changes in blood pressure (BP), heart rate (HR) response and plasma epinephrine (E) and norepinephrine (NE) levels induced by stimulation of the sympathetic spinal cord outflow were studied in pithed stroke-prone spontaneously hypertensive rats (SHRSP). Surgical pithing significantly reduced plasma E but not NE levels suggesting that the sympathoadrenal medullary system differentially affects E and NE release. Sympathetic stimulation of the spinal cord of pithed SHRSP increased HR, BP, plasma E and NE levels. Topically applied CL 115,347 (0.001-0.2 mg/kg) dose-dependently decreased BP, while intravenously infused PGE2 (30 micrograms/kg/min) did not alter BP except for a brief initial drop. Topical application of CL 115,347 (0.1 mg/kg) also inhibited BP responses to sympathetic stimulation without effects on HR or plasma E or NE levels. Intravenous infusion of PGE2 (30 micrograms/kg/min) inhibited both BP and HR responses to spinal cord stimulation but did not alter plasma catecholamine levels. These studies in SHRSP suggest that CL 115,347 and PGE2 modulate cardiovascular responses mainly via postjunctional effects, but act differently on the cardiovascular elements, viz. CL 115,347 acts primarily on blood vessels while PGE2 acts on blood vessels and heart.
