Abstract: Supplemented livestock feedstuffs and methods of feeding using as active ingredient a chemical compound having histamine H.sub.2 antagonist activity improve the utilization of food by meat producing animals. A specific compound of use as the active ingredient is metiamide.
Abstract: 3-Furylmethyl- and thienylmethyl-6-halo-7,8-dihydroxy-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzaz epines have potent dopaminergic activity. As such they have utility an antihypertensive and anti-Parkinsonism agents.
Abstract: Imidodisulfamide derivatives useful in the treatment of allergic conditions are prepared by reaction of an appropriately substituted phenylcycloalkylamine and bis(chlorosulfonyl)imide in the presence of a non-nucleophilic organic base. Pharmaceutical compositions and methods of inhibiting the symptoms of an allergic response are also disclosed.
Abstract: Imidosulfamide derivatives useful in the treatment of allergic conditions are prepared by reaction of an appropriately substituted tetrahydroisoquinoline and chlorosulfonylisocyanate in the presence of a non-nucleophilic organic base. Pharmaceutical compositions and methods of inhibiting the symptoms of an allergic response are also disclosed.
Abstract: The preparation and use as intermediates is described for 7,8-dihydroxy-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepines whose structures are characterized by having either an aralkyl or lower alkanoyl group at position 2 or an .alpha.-hydroxyalkyl or .alpha.-chloroalkyl group at position 6.
Abstract: A process for preparing 3-chloro-6-(2-hydroxyphenyl)pyridazines by the reaction of 6-(2-hydroxyphenyl)-3(2H)-pyridazinones with phosphorus oxychloride and a disubstituted formamide. The chloropyridazine compounds are useful intermediates for preparing compounds which have .beta.-adrenergic blocking and vasodilator activity and are useful as antihypertensive agents.
Abstract: 4-Phenyl-1,2,3,4-tetrahydroisoquinolines whose structures have two hydroxy groups substituted at the 3,4-position on the 4-phenyl ring have been found to have renal vasodilating activity upon internal administration. The active ingredients are prepared by cyclizing N-(2-substituted benzyl)-1-(3,4-dimethoxyphenyl)-aminoethanol using either a Lewis acid or an acid cyclizing agent followed by demethylation at the 3,4-dimethoxyphenyl moiety.
Abstract: A new series of compounds having renal vasodilating activity described. The compounds are 2-allyl-8-halo-4-(p-hydroxyphenyl)-1,2,3,4-tetrahydroisoquinolines.
Abstract: Pharmaceutical compositions having as active diuretic ingredients certain 4-guanidinopyridines are described. Representative diuretic compounds are 5-amino-6-chloro-4-guanidinopyrimidine and 6-amino-5-nitro-4-guanidinopyrimidine.
Abstract: 2,4-Amino, guanidinopyrimidines have diuretic activity. A representative species of these compounds is 2-guanidino-4-amino-6-chloroguanidine which is prepared by the stepwise replacement of first the 2-halo of a 2,4,6-trihalopyrimidine by guanidino and then the 4-halo by ammonia.
Abstract: A group of new chemical compounds are described which are intermediates for preparing 7,8-amino, hydroxy-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepines. The intermediates are distinguished in structure by a benzyloxy substituent at either the 7 or 8-position.
