[1,4]Benzodioxanylmethyl-, [1,4]benzodioxanylmethylaminopropyl- and ph
enoxyethylaminoethyl-substituted lactams were synthesised and their hy
potensive activity was investigated. Some of these compounds show mode
rate to high hypotensive effect, but they had more toxic and/or side e
ffects than GYKI-12 743.
