Abstract: Oxothia compounds, especially 2-oxo-2,3-dihydro-benzo[b]-thiophene compounds of the formula ##STR1## in which Ph represents an optionally substituted 1,2-phenylene radical, X represents oxygen or sulphur, R.sub.1 represents an organic radical bonded via a carbon atom and R.sub.2 denotes hydrogen or an optionally substituted hydrocarbon radical of aliphatic character, and their salts are useful as peripheral analgetics and/or as antiphlogistic uricosuric and/or thrombolytic agents.

Abstract: The invention relates to the dextrorotatory enantiomer of trans-5,6-di-p-methoxyphenyl-2,3,5,6-tetrahydroimidazo[2,1-b]thiazole and its pharmaceutically acceptable salts and to pharmaceutical preparations containing them.The new compounds have valuable pharmacological properties, especially anti-inflammatory and anti-rheumatic effects.

Abstract: Oxothia compounds, especially 2-oxo-2,3-dihydro-benzo[b]-thiophene compounds of the formula ##STR1## in which Ph represents an optionally substituted 1,2-phenylene radical, X represents oxygen or sulphur, R.sub.1 represents an organic radical bonded via a carbon atom and R.sub.2 denotes hydrogen or an optionally substituted hydrocarbon radical of aliphatic character, and their salts are useful as peripheral analgetics and/or as antiphlogistic uricosuric and/or thrombolytic agents.

Abstract: Compounds of the formula ##STR1## in which R.sub.1 and R.sub.2 independently of one another are substituted or unsubstituted aryl or hetero-aryl groups, R.sub.3 is hydrogen or lower alkyl and R.sub.4 is a substituted or unsubstituted aliphatic hydrocarbon radical, and their pharmaceutically usable salts. These compounds possess immunoregulatory, antithrombotic and antiinflammatory properties and can be used as active ingredients in medicaments. They are prepared, for example, by reacting compounds of the formulae ##STR2## in which one of the radicals X and Y is mercapto, which can be in the form of a salt, and the other is a radical replaceable by etherified mercapto, with one another.

Abstract: New carboxylic acid hydrazides of the formula ##STR1## in which R represents an optionally esterified carboxy group,and salts of the compound of the formula I, in which R represents carboxy, possess antithrombotic properties and can be used as medicinal active substances in pharmaceutical preparations.

Abstract: The invention relates to novel ortho-aminoacetophenones of the formula I ##STR1## and their tautomers, in which Z is hydrogen, halogen, lower alkyl, cycloalkyl, lower alkoxy, trifluoromethyl, nitro or substituted or unsubstituted sulphamoyl, m is 1 or 2, R is hydrogen, aryl or lower alkyl, R.sub.1 is hydrogen or lower alkyl, R.sub.2 is lower alkyl, cycloalkyl, aryl, cycloalkyl-lower alkyl, aryl-lower alkyl or substituted or unsubstituted pyridyl, R.sub.

Abstract: Novel benzoheterocyclylglyoxylic acid derivatives of the formula ##STR1## in which Z is free, etherified or acylated hydroxyl, X is thio or oxy, R is free or etherified hydroxyl, R.sub.1 is lower alkyl, cycloalkyl, hydroxyl, lower alkoxy, substituted or unsubstituted phenoxy, substituted or unsubstituted amino, acyl, carboxyl, halogen, nitro or, if Z is acylated hydroxyl and/or X is oxy, hydrogen, R.sub.2 is hydrogen, lower alkyl, hydroxyl or halogen and R.sub.3 and R.sub.4 are each hydrogen or lower alkyl, or in which two adjacent radicals R.sub.1, R.sub.2, R.sub.3 and R.sub.4 together form lower alkylene having 3 to 5 chain carbon atoms or 1,4-butadienylene and the other two radicals are each hydrogen, and their pharmaceutically acceptable salts are useful as anti-allergic agents.

Abstract: Compounds of the formula ##SPC1##Wherein Ar denotes an optionally substituted phenyl group or hetero-aromatic group with 5 or 6 ring members wherein the atom directly bonded to the quinoline ring is a carbon atom, R.sub.1 represents hydrogen, halogen, lower alkyl, lower alkoxy or trifluoromethyl and R.sub.2 and R.sub.3 independently of one another denote hydrogen or a lower alkyl group, esters and amides of these carboxylic acids or salts of such compounds, have anti-inflammatory and analgesic activity; they are active ingredients of pharmaceutical compositions and can be used for the relief and removal of pain as well as for the treatment of rheumatic, arthritic and other inflammatory complaints; an illustrative example is .alpha.-methyl-2-(2-thienyl)-6-quinolineacetic acid.
