Abstract: AIM: To observe the influence of alkyl-1,2,5,6-tetrahydro-3-substitutedPyridine analogy compounds on the function of endothelial cells.METHODS: The effects ofl-NAME,indomethacin,pilocarpine and atropine on the novel compounds were observed using the isolated rat aorta and guineaPig ileum model.RESULTS: Among 100 compounds,4leading compounds were found,which included HH91,HH95,HH98,and HH103.The endothelium-dependent relaxation mediated by HH103 could be blocked byl-NAME,but not by indomethacin,pilocarpine and atropine.CONCLUSION: The novel compounds can mediate endothelium-dependent relaxation and had unique structure-activity relationship.The function of endothelium-dependent relaxation mediated by HH103 isPerformed byPromoting the secrete of NO,but different from that of ACh.
