4-Alkyl-2,6-di-(secondary or tertiary alkyl)amino-3-formylpyridines

4-Alkyl-2,6-di(secondary or tertiary alkylamino) pyridines, compositions

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.

Hydroxyalkyl-substituted-amino-quinolines

Disclosed are bi-4-[1-(quinazolinyl-4)piperidyls] and bis{4-[1-(quinazolinyl-4)piperidyl]alkanes}, e.g. 1,3-bis{4-[1-(6,7-dimethylquinazolinyl-4)piperidyl]propane}, having pharmacological activity in animals and useful for example, as anti-obesity and anti-diabetic agents. Said compounds may be prepared by reacting a 4-haloquinazoline with bi-4-piperidyl or a bis(piperidyl-4)alkane.

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.

Hydroxyalkyl-piperazino-quinoline nitrates

Disclosed are compounds of the class of quinazolines substituted at the 2-position by lower alkyl and at the 4-position by an amino function bearing a hydroxy-alkyl nitrate moiety, e.g., 4-(5-hydroxypentyl) amino-2-methyl-6,7-dimethoxy-quinazoline nitrate. The compounds and their corresponding hydroxy intermediates have various pharmacological activities in animals and are useful, for example, as anti-anginal agents and as agents in the treatment of shock.

2-Alkyl-4-substituted amino-quinazolines and nitrates thereof in the

Disclosed are compounds of the class of furo[3,2-c]pyridines substituted at the 4-position by an amino function bearing a hydroxy-alkyl nitrate moiety, e.g., 4-[ 4-(2-hydroxyethyl)-1-piperazino]-furo[3,2-c]pyridine nitrate. The compounds have pharmacological activity in animals and are useful, for example, as anti-anginal agents. Also disclosed are the corresponding hydroxy intermediates which are useful in preparation of the nitrates and also as anti-anginal agents or as agents in the treatment of shock.

4-(Hydroxy-substituted-amino)-furo[3,2-c]pyridines

Disclosed are compounds of the class of isoquinolines substituted at the 1-position by an amino function bearing a hydroxy-alkyl nitrate moiety, e.g., 1-(5-hydroxypentyl)-amino-6,7-methylene-dioxyisoquinoline nitrate. The compounds have various pharmacological activities in animals and are useful, for example, as anti-hypertensive agents, anti-anginal agents and in the treatment of shock. Also disclosed are the corresponding hydroxy intermediates which are useful in preparation of the nitrates and also as hypotensive agents or as agents in the treatment of shock.

1-(4-Hydroxyalkylpiperazino)-isoquinoline nitrates

Disclosed are N,N'-Bis(4-Quinazolinyl)alkanediamines, e.g., N,N'-Bis(7-chloro-4-quinazolinyl)-1,9-nonanediamine, having pharmacological activity in animals and useful for example, as anti-obesity agents. Said compounds may be prepared by reacting a 4-haloquinazoline with an alkanediamine.
