Abstract: 4-Phenoxypiperidines of the general formula I ##STR1## wherein R.sup.1 denotes a hydrogen atom, an alkyl group with 1 to 5 carbon atoms, an alkenyl group with 3 to 5 carbon atoms, a cycloalkylmethyl group with 3 to 7 carbon atoms in the cycloalkyl part or a phenylalkyl group with 1 to 3 carbon atoms in the alkyl part,R.sup.2 denotes a hydrogen atom, a nitro group, an amino group or an acylamino group andR.sup.3 denotes a phenyl group or a benzyl group,and their N-oxides and their acid-addition salts are new compounds. They have an antiptotic and analgesic action and are suitable for the treatment of depressions and painful conditions. Processes for the preparation of the new compounds are provided.

Abstract: 11-Acyl-2-phenyl- and 11-acyl-5,6-dihydropyrimido[4,5-b][1,5]benzodiazepin-5-ones, their acid-addition salts and their N-oxides provide protective action for the stomach and intestines of warm-blooded animals and inhibit the formation of gastric and intestinal ulcers.

Abstract: 2-Benzylpyrrolidines bearing from 1 to 4 nuclear substituents on the benzyl ring are pharmacologically active, particularly on the CNS, on blood pressure and on pain sensation for warm-blooded animals. They are synthesized, e.g., by reducing appropriate 2-benzylpyrrolidines and are formulated into medicament compositions according to established conventional techniques.

Abstract: 2-[(O-ALKYLAROYLHYDRAZONO)PROPEN-1-YL]-5-NITROFURANS [1] ARE PREPARED BY CONDENSING 3-(5-NITRO-2-FURYL)ACRYLALDEHYDE [2] WITH AN O-ALKYLAROYL HYDRAZIDE [3]. Compounds [1] are bactericides, protozoacides and fungicides and are administrable to animals in therapeutically-acceptable compositions.
