The invention relates to new thiazole compounds, of antithrombotic, vasodilating, antiallergic, antiinflammatory and 5-lipoxygenase inhibitory activity, of the formula: ##STR1## wherein A is lower alkylene or carbonyl; R.sup.1 and R.sup.2 are each halogen, lower alkyloxy, lower alkylthio or lower alkylsulfinyl; R.sup.3 is acyl derived from an aliphatic carboxylic or carbamic acid; and R.sup.4 is hydrogen, lower alkyl, amidino or acyl derived from an aliphatic carboxylic or carbamic acid, or the pharmaceutically acceptable salt thereof.
Novel naphthyridine-, quinoline- and benzoxazine-carboxylic acids as antibacterial agents are described as well as methods for their manufacture, formulation, and use in treating bacterial infections including the description of certain novel intermediates used in the manufacture of the antibacterial agents.
derivatives and relatedcompounds were synthesized and evaluated for histamineH2-receptorantagonist and gastric acid antisecretory activities. Among them, compounds I-17, I-48 and I-49 showed high activities in these tests. In addition, compound I-17 possessed potent inhibitory activities on each of the gastric ulcers induced by stress, ethanol and HCl-aspirin. On the other hand, compound I-48 demonstrated

4-dihydro-4-oxo-7-(4-thiazolyl)-3-quinolinecarboxylic acids and 1-ethyl-1,4-dihydro-4-oxo-7-(2-thiazolyl)-3-quinolinecarboxylic acids were prepared. Also prepared was 10-[2-(aminomethyl)-4-thiazolyl]-9-fluoro-2,3-dihydro-3-methyl-7-oxo-7H-pyrido[1,2,3-de][1,4]benzoxazine-6-carboxylic acid. Analogs with basic amine substituents on the thiazole moiety were found to have antibacterial activity.

Formation of 5-acetamido-substituted thiazoles was found to be readily effective on heating 2-(acylamino)thioacetamides with acetic anhydride. In additon, preparation of some starting 2-(acylamino)thioacetamides is described and 5-acetamidothiazole-4-carboxamides obtained by the thiazole formation reaction were led to some thiazolo[5, 4-d]pyrimidines.
