N.sub.1 -acyl-N.sub.2 -phenyl-1,3-diaminopropan-2-ols are disclosed which possess ulcer-inhibiting activities. Further disclosed are pharmaceutical compositions which are effective in the treatment and prophylaxis of ulcers and which comprise as a pharmacologically active ulcus-inhibiting ingredient N.sub.1 -acyl-N.sub.2 -phenyl-1,3-diaminopropan-2-ols, or a pharmaceutically acceptable acid addition salt thereof, and a pharmaceutically acceptable diluent. Further disclosed are processes for the preparation of the N.sub.1 -acyl-N.sub.2 -phenyl-1,3-diaminopropan-2-ols.

N.sub.1 -Acyl-N.sub.2 -phenyl-diaminopropanols and pharmaceutical

Disclosed is a process for the production from raw lecithin of pure lecithin directly usable for physiological purposes, comprising the steps of contacting raw lecithin with gas as the extraction medium under supercritical conditions with respect to pressure and temperature in an extraction stage to produce a gas containing an extract; passing the gas containing the extract from the extraction stage into a separation stage; varying at least one of the pressure and the temperature of the gas in the separation stage to separate the extract-containing gas into the gas and the extract; recycling the gas after the step of varying the pressure and/or temperature; and removing pure lecithin from the extraction stage.

N.sub.1 -benzoyl-N.sub.2 -phenyl-1,3-diaminopropan-2-ols are disclosed which exhibit a stabilizing effect on the gastric mucosa and enhance the stability and resistance of the gastic mucosa against harmful effects caused by, e.g., excessive alcohol consumption or drugs. The compounds are useful in the prophylaxis and treatment of gastritis. Further disclosed are pharmaceutical compositions which are effective in stabilizing the gastric mucosa and in the treatment and proplylaxis of gastritis and which comprise as a pharmacologically active ingredient N.sub.1 -benzoyl-N.sub.2 -phenyl-1,3-diaminopropan-2-ols, or a pharmaceutically acceptable acid addition salt thereof, and a pharmaceutically acceptable diluent. Further disclosed are processes for the preparation of the N.sub.1 -benzoyl-N.sub.2 -phenyl-1,3-diaminopropan-2-ols.

N.sub.1 -acyl-N.sub.2 -phenyldiaminopropanols and pharmaceutical

Pharmaceutical compositions are disclosed, which are effective in the treatment and prophylaxis of ulcers and which comprise as a pharmacologically active ulcus-inhibiting ingredient a compound selected from the group of N.sub.1 -acyl-N.sub.2 -(4-chlorophenyl)-1,3-diaminopropan-2-ols, having the formula I ##STR1## wherein R.sub.1 represents 3,4-dimethoxyphenyl, 2-fluorophenyl, 2-trifluoromethylphenyl, or furyl, and pharmaceutically acceptable acid addition salts thereof, and a pharmaceutically acceptable diluent. Further disclosed is a new process for the preparation of the compounds of formula I.

Pharmaceutical compositions of N.sub.1 -acyl-N.sub.2

New 1,4-benzodiazepine derivatives are disclosed which are substituted in 2-position by cyanomethylene or carbamoylmethylene and have the formula ##STR1## wherein R.sub.1 represents hydrogen, halogen, or nitro, R.sub.2 represents hydrogen or lower alkyl, R.sub.3 represents phenyl which may be substituted by halogen or CF.sub.3, and R.sub.4 represents cyano or carbamoyl. The compounds exhibit tranquilizing activities. The cyanomethylene-compounds are prepared by oxidizing corresponding cyanomethyl compounds with Cr-VI-oxide in an acidic reaction medium. The cyanomethylene-group can subsequently be hydrolyzed into the carbamoylmethylene group.
