title: Effects of the isocarbacyclin methyl ester clinprost incorporated into lipid microspheres, in focal ischemia of stroke-prone spontaneously hypertensive rats.
abstract: The effects of TTC-909, the isocarbacyclin methyl ester clinprost (CAS 88931-51-5), incorporated into lipid microspheres, on ischemia-induced decrease in norepinephrine (NE) contents in stroke-prone spontaneously hypertensive rats (SHR-SP) with an occluded middle cerebral artery (MCA) were examined. Occluding of MCA led to infarction limited to the cerebral cortex and also a severe decrease in NE contents in peripheral regions of the infarction. TTC-909 was injected immediately after MCA occlusion, and then daily for 6 consecutive days. As TTC-909 in a dose of 200 ng/kg significantly (p < 0.05) prevented decreases in NE contents, TTC-909 may have cytoprotective effects on neuronal damage related to ischemia in humans.
