Flavones. 1. Synthesis and antihypertensive activity of (3-phenylflavonoxy)propanolamines without beta-adrenoceptor antagonism.

Journal of Medicinal Chemistry, 1987
The synthesis of a series of (3-phenylflavonoxy)propanolamines is described. These compounds were evaluated for potential antihypertensive activity in spontaneously hypertensive rats, as well as for in vivo and in vitro evidence of beta-adrenoceptor ...

Beta-Adrenergic blocking agents. Nitrogen heteroaryl-substituted 2-propanolamines and ethanolamines.

Journal of Medicinal Chemistry, 1973
AbstractEine Reihe von Methylheterocyclen (I) wird in Form ihrer Lithiumderivate (II) mit den Aminoacetonitrilen (III) zu den Enaminen (IV) umgesetzt, die durch Hydrolyse, Reduktion mit Natriumborhydrid und hydrierende Debenzylierung in Propanolamine (VII) umgewandelt werden.

Persistence and Biodegradation of Monoethanolamine and 2-Propanolamine at an Abandoned Industrial Site

Environmental Science & Technology, 2005
Soil and groundwater samples were collected at the site of a former chemical processing plant in areas impacted by accidental releases of MEA (monoethanolamine) and IPA (2-propanolamine or isopropanolamine). Although their use had ceased ca. 10 years before sample collection, soils collected at contamination sites had MEA concentrations ranging from ca.

3-(Acyloxy)propanolamines : agents with β-adrenergic blocking activity

European Journal of Medicinal Chemistry, 1994
Abstract A series of totally aliphatic 3-(acyloxy)propanolamine derivatives were prepared and their pA2-values were determined employing the guinea-pig atrium. Compounds with an acetyl or methyl succinoyl half ester moiety showed a pronounced β1-adrenergic blocking activity.

o-Allyloxy-phenoxy-propanolamine, eine neue Gruppe adrenergischer β-Rezeptoren-Blocker

Experientia, 1967
The synthesis of a new class of adrenergicβ-receptor blocking agents based upon ao-allyloxy-phenoxy-propanolamine structure is described. The structure activity relationships were studied, and the structural elements responsible for an optimal pharmacological effect are discussed.

A new series of tricyclic (aryloximino)propanolamines displaying very high selective .beta.2-blocking properties

Journal of Medicinal Chemistry, 1989
A new class of indanones 4 easily obtained by aryne type condensations, followed by transposition of the benzocyclobutanols 3 thus formed, were transformed into the corresponding oximinopropanolamines 7.

Crystal structure and magnetic properties of a Cu4O4 cubane complex with N-(2-hydroxybenzyl)-propanolamine

Inorganic Chemistry Communications, 2001
Abstract The crystal structure of [ Cu ( L 1 )] 4 ( 1 ) (H2L1=N-(2-hydroxybenzyl)-propanolamine) contains a Cu4O4 cubane core, involving four intramolecular hydrogen bonds. Magnetic studies reveal a good linear correlation between 2J and the bridge angle φ; the more antiferromagnetic trend than the literature correlations for ...

A first-principle study of CO2 binding by monoethanolamine and mono-n-propanolamine solutions

Chemical Physics, 2015
Abstract Monoethanolamine (MEA) and mono- n -propanolamine (MPA) molecules were investigated for CO 2 binding using Density Functional Theory. MPA was predicted to bind CO 2 better than MEA along the bimolecular and trimolecular pathways. The additional CH 2 in MPA provided additional polarization to reduce the electrostatic repulsion for the ...
