摘要:
New compounds of the general formula (I), ##STR1## wherein R.sub.1 and R.sub.2 each stand for a saturated or unsaturated, straight-chained or branched alkyl group, an aralkyl group, a saturated or unsaturated cycloalkyl group or an aryl group, orR.sub.1 and R.sub.2 together with the adjacent nitrogen atom may form an optionally substituted heterocyclic group optionally containing a further oxygen or nitrogen hetero atom,But if R.sub.1 stands for methyl, R.sub.2 may only stand for a group other than methyl, are prepared by reacting a compound of the general formula ##STR2## wherein X stands for halogen, with a secondary amine of the general formula (III),r.sub.1 --nh--r.sub.2 (iii)wherein R.sub.1 and R.sub.2 each have the same meanings as defined above.The new compounds of the general formula (I), as well as their pharmaceutical acceptable acid addition salts or quaternary ammonium salts are active primarily in the induction of liver microsomal enzyme, but they also possess antipyretic activity.

(iii)the new compounds of the general formula (I), as well as their pharmaceutical acceptable acid addition salts or quaternary ammonium salts are active primarily in the induction of liver microsomal enzyme, but they also possess antipyretic activity.
摘要:
The invention relates to the preparation of biologically active polypeptides containing the aspartyl group, particularly an aspartyl-glycine moiety, using the active-ester technique.According to the method of the invention, human adrenocorticotropic hormone and its fragments characteristic to the individual species, as well as the blocked derivatives of such compounds are prepared by the pentafluorophenol method, i.e., the carboxy group of the acylating component is activated by converting it into pentafluorophenyl ester in the coupling reaction carried out with blocked peptides containing the aspartyl group or an aspartylglycine moiety. The acylation is carried out preferably using equimolar quantities of the respective reactants. The free peptides obtained after removing the blocking groups can be converted into their acid addition salts or pharmaceutically acceptable complexes or condensates.Human adrenocorticotropic hormone and its derivatives are valuable substances of therapeutical activity.
