Abstract: Novel 1-aryloxy-3-amidoamidoalkylamino-2-propanol derivatives, processes for their manufacture, pharmaceutical compositions containing them and methods of using them in the treatment of heart diseases. Representative of the compounds disclosed is 1-(o-cyanophenoxy)-3-.beta.-(2-thenamidoacetamido)ethylaminopropan-2-ol.
Abstract: 4-(Thien-2-oyl- and thien-3-oylphenyl)pentan-2-ones and 4-(thien-2-oyl- and thien-3-oylphenyl)butan-2-ones, the corresponding pentan-2-ols and butan-2-ols, and esters of the latter alkanols are anti-inflammatory agents. The compounds, of which 4-[4-(2-thienoyl)phenyl]pentan-2-one is a representative embodiment, can be prepared by acylation of the corresponding 4-phenylpentan-2-one, 4-phenylbutan-2-one, or an ester of the corresponding pentan-2-ol or butan-2-ol, with a thienylcarboxylic acid, or by acylation of a 4-(4-carboxyphenyl)pentan-2-one, 4-(4-carboxyphenyl)butan-2-one or an ester of the corresponding pentan-2-ol or butan-2-ol with thiophene, optionally in either case with subsequent reduction of the resultant alkanone and with optional esterification of the resultant alkanol.
