Synthesis and hypotensive activity of benzopyran derivatives.

Chemical and Pharmaceutical Bulletin, 1987
A series of dihydrobenzopyranyloxypropanolamines and dihydrobenzopyranylethanolamines containing a nitroxy moiety was synthesized. The cardiovascular effects of these compounds were investigated in anesthetized dogs. Some of the compounds exhibited hypotensive activity in combination with β-adrenergic blocking and vasodilating action.
