Abstract
Abstract Disclosed are compounds of the class of quinolines substituted at the 2-, 3- or 4- position by an amino function bearing a hydroxyalkyl nitrate moiety, e.g. 4-(2-hydroxyethylpiperazino)quinoline nitrate. The compounds have various pharmacological activities in animals and are useful, for example, as hypotensive and anti-anginal agents. Also disclosed are the corresponding hydroxy intermediates which are useful in preparation of the nitrates and also as hypotensive and anti-anginal agents.
